Spring,hibernate,struts的结合做分页的例子-优快云博客

本文链接：https://blog.youkuaiyun.com/wangghost/article/details/1111409

一段时间以来时间很忙，自己的技术blog也被当作了"Silent hill"了，呵呵！今天有点时间还是把刚写的例子贴上blog巴。

废话不多说，为了方便还是直接贴代码了。

实验环境：tomcat 5.1 IDE:Eclilpse 4.1 oracle9i Spring1.2 struts1.1 Hibernate3

一、先来看看几个xml巴：

1.先是 applicationContext.xml，其中定义了dbcp和jndi数据库连接池，两种方式连接数据库！

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

<value>oracle.jdbc.driver.OracleDriver</value>

</property>

<value>jdbc:oracle:thin:@localhost:1521:CCTV</value>

</property>

</property>

</property>

</bean>

<value>java:comp/env/jdbc/testds</value>

</property>

</bean>

</property>

<list>

<value>com/test/common/hibernate/daos/Customer.hbm.xml</value>

<value>com/test/common/hibernate/daos/Account.hbm.xml</value>

</list>

</property>

<props>

<prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>

</props>

</property>

</bean>

</property>

</bean>

<!-- hibernate 事务AddCustomerDAOProxy的transactionAttributes属性中，

定义事务策略将所有以save、remove开始的方法纳入事务管理范围，

如果这些方法抛出异常，在Spring将当前事务回滚，如果方法正常结束，则提交事务。

-->

</property>

</property>

<props>

<prop key="insert*">PROPAGATION_REQUIRED</prop>

<!-- prop key="get*">PROPAGATION_REQUIRED</prop>

<prop key="set*">PROPAGATION_REQUIRED</prop>

<prop key="modify*">PROPAGATION_REQUIRED,-BoardException</prop>

<prop key="remove*">PROPAGATION_REQUIRED,-BoardException</prop-->

</props>

</property>

</bean>

</property>

</property>

<props>

<prop key="get*">PROPAGATION_REQUIRED</prop>

<!-- prop key="set*">PROPAGATION_REQUIRED</prop>

<prop key="modify*">PROPAGATION_REQUIRED,-BoardException</prop>

<prop key="remove*">PROPAGATION_REQUIRED,-BoardException</prop-->

</props>

</property>

</bean>

</property>

</property>

</bean>

</property>

</bean>

</property>

</bean>

</property>

</bean>

</property>

</bean>

<!-- bean id="wordCaseUtil" class="com.test.common.springwork.dao.WordTools">

</property>

</property>

</bean-->

</beans>

接着看一下tomcat在server.xml的datasource的配置：

<name>factory</name>

<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>

</parameter>

<name>driverClassName</name>

<value>oracle.jdbc.driver.OracleDriver</value>

</parameter>

<value>jdbc:oracle:thin:@localhost:1521:wang</value>

</parameter>

<name>username</name>

</parameter>

<name>password</name>

</parameter>

<name>maxActive</name>

</parameter>

<name>maxIdle</name>

</parameter>

<name>maxWait</name>

</parameter>

</ResourceParams>

</Context>

2.再来看看web.xml的配置！

其中启用了Spring的ContextLoaderListener来做监听，而不是配置servlet

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>

<context-param>

<param-value>/WEB-INF/applicationContext.xml</param-value>

</context-param>

</listener>

<servlet-name>action</servlet-name>

<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>

<init-param>

</init-param>

<load-on-startup>10</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>action</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

<taglib-uri>/WEB-INF/struts-bean.tld</taglib-uri>

<taglib-location>/WEB-INF/struts-bean.tld</taglib-location>

</taglib>

<taglib-uri>/WEB-INF/struts-logic.tld</taglib-uri>

<taglib-location>/WEB-INF/struts-logic.tld</taglib-location>

</taglib>

<taglib-uri>/WEB-INF/page.tld</taglib-uri>

<taglib-location>/WEB-INF/page.tld</taglib-location>

</taglib>

<resource-ref>

<res-ref-name>jdbc/testds</res-ref-name>

<res-type>javax.sql.DataSource</res-type>

<res-auth>Container</res-auth>

<res-sharing-scope>Shareable</res-sharing-scope>

</resource-ref>

</web-app>

3.web层也就是struts的struts-config.xml的配置略有不同，它需要加上插件，在容器启动时自动加载 applicationContext.xml，并且action可以通过spring beans来以来注入，所以要用到：org.springframework.web.struts.DelegatingActionProxy

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>

<form-beans >

<form-bean name="addPersonForm" type="com.test.common.struts.actionforms.AddPersonActionForm" />

</form-beans>

<action-mappings>

<action

name="addPersonForm"

validate="false"

path="/jsp/addPerson"

scope="request"

type="org.springframework.web.struts.DelegatingActionProxy">

</action>

<action

path="/jsp/ShowListAction"

scope="request"

type="org.springframework.web.struts.DelegatingActionProxy">

</action>

</action-mappings>

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">

<set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml"/>

</plug-in>

</struts-config>

二、需要配置的两个表的hbm.xml也就是hibernate对表的配置文件，其中TBL_CUSTOMER是主表TBL_ACCOUNT是从表，TBL_ACCOUNT有外键：CUSTOMER_ID，本例子的dao层要做对其二表的及联添加！

1。Customer.hbm.xml

<?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC

"-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

<hibernate-mapping>

<class

name="com.test.common.hibernate.daos.Customer"

table="TBL_CUSTOMER"

dynamic-update="false"

dynamic-insert="false">

<id

name="id"

column="CUSTOMER_ID"

type="java.lang.Long"

unsaved-value="-1"

</generator>

</id>

<set name ="accounts"

inverse = "true"

cascade="save-update">

<one-to-many class="com.test.common.hibernate.daos.Account"/>

</set>

<property

name="email"

type="string"

update="false"

insert="true"

column="CUSTOMER_EMAIL"

length="82"

not-null="true"

<property

name="password"

type="string"

update="false"

insert="true"

column="CUSTOMER_PASSWORD"

length="10"

not-null="true"

<property

name="userId"

type="string"

update="false"

insert="true"

column="CUSTOMER_USERID"

length="12"

not-null="true"

unique="true"

<property

name="firstName"

type="string"

update="false"

insert="true"

column="CUSTOMER_FIRSTNAME"

length="25"

not-null="true"

<property

name="lastName"

type="string"

update="false"

insert="true"

column="CUSTOMER_LASTTNAME"

length="25"

not-null="true"

</class>

</hibernate-mapping>

2。Account.hbm.xml

<?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC

"-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

<hibernate-mapping>

<class

name="com.test.common.hibernate.daos.Account"

table="TBL_ACCOUNT"

dynamic-update="false"

dynamic-insert="false">

<id

name="id"

column="ACCOUNT_ID"

type="java.lang.Long"

unsaved-value="-1"

</generator>

</id>

<many-to-one

name="customer"

column="CUSTOMER_ID"

cascade="save-update"

class="com.test.common.hibernate.daos.Customer"

<property

name="accountName"

type="string"

update="false"

insert="true"

column="ACCOUNT_NAME"

length="50"

not-null="true"

<property

name="type"

type="string"

update="false"

insert="true"

column="ACCOUNT_TYPE"

length="1"

not-null="true"

<property

name="createDate"

type="date"

update="false"

insert="true"

column="CREATE_DATE"

not-null="true"

<property

name="updateDate"

type="date"

update="true"

insert="true"

not-null="true"

column="UPDATE_DATE"

<property

name="balance"

type="double"

update="true"

insert="true"

column="ACCOUNT_BALANCE"

not-null="true"

</class>

</hibernate-mapping>

接下来看一看这两个表的dao层接口及实现接口的类：

（1）、accountDao和accountDaoImpl

/**

* @author wangghost

* @deprecated:account数据操作接口！

public interface AccountDAO {

public abstract void addAccount(Account account);

}

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

/**

* @author wangghost

* @deprecated:实现account接口！

* @see:AccountDAO.java

public class AccountDAOImpl extends HibernateDaoSupport implements AccountDAO{

public void addAccount(Account account) {

getHibernateTemplate().save(account);

}

（2）、customerDao和customerDaoImpl

/**

* @author wangghost

* @deprecated:customer数据模型接口！

public interface CustomerDAO {

public abstract void addCustomer(Customer customer);

public abstract Customer getCustomerAccountInfo(Customer customer);

public abstract void deleteCustomerInfo(Customer customer);

}

对应application-context.xml中的bean

</property>

</bean>

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

/**

* @author wangghost

* @deprecated:实现customer接口！

* @see:CustomerDAO.java

public class CustomerDAOImpl extends HibernateDaoSupport implements CustomerDAO{

public void addCustomer(Customer customer) { //hibernate 被spring 封装接口方法getHibernateTemplate（）用它来调用hibernate数据库操作

getHibernateTemplate().save(customer);

getHibernateTemplate().flush();

// TODO Auto-generated method stub

}

public Customer getCustomerAccountInfo(Customer customer) {//根据userid得出相应持久化对象

Customer cust = null;

List list = getHibernateTemplate().find("from Customer customer " +

"where customer.userId = ?",new Object[]{

customer.getUserId()});

// List list = getHibernateTemplate().find("from Customer customer " +

// "where customer.userId = "+customer.getUserId(),Hibernate.STRING); //hibernate 2 写法，这里已经不支持了！

if(list.size() > 0){

cust = (Customer) list.get(0);

}

return cust;

}

public void deleteCustomerInfo(Customer customer) {

// TODO 自动生成方法存根

}

三、service层，由于此例子也无非常简单，但为了遵循三个框架的意见还是添加了service层。

1。接口CustomerDAOService与它的接口实现CustomerDAOServiceImpl：

import com.test.common.struts.actionforms.AddPersonActionForm;

/**

* @author wangghost

* 更改所生成类型注释的模板为窗口 > 首选项 > Java > 代码生成 > 代码和注释

public interface CustomerDAOService {

public abstract void customerService(AddPersonActionForm person,

String userid, java.sql.Date date);

}

import com.test.common.hibernate.daos.Account;

import com.test.common.hibernate.daos.Customer;

import com.test.common.hibernate.daos.CustomerDAO;

import com.test.common.struts.actionforms.AddPersonActionForm;

/**

* @author wangghost

* 更改

* 窗口 > 首选项 > Java > 代码生成 > 代码和注释

public class CustomerDAOServiceImpl implements CustomerDAOService {

/**

public CustomerDAOServiceImpl() {

super();

}

private CustomerDAO customerDAO;

/**

* @return Returns the customerDAO.

public CustomerDAO getCustomerDAO() {

return customerDAO;

}

/**

* @param customerDAO

* The customerDAO to set.

public void setCustomerDAO(CustomerDAO customerDAO) {

this.customerDAO = customerDAO;

}

* @see com.test.common.springwork.service.CustomerDAOService#customerService()

public void customerService(AddPersonActionForm person,String userid,java.sql.Date date) {

// let user info into "pojo" customer

Customer customer = new Customer();

customer.setFirstName(person.getFristname().trim());

customer.setLastName(person.getLastname().trim());

customer.setEmail(person.getEmail());

customer.setPassword(person.getPassword().trim());

customer.setUserId(userid);

// customer done!

// account begin!

Account account = new Account();

account.setAccountName(person.getAccountname());

account.setCreateDate(date);

account.setUpdateDate(date);

account.setType(person.getAccounttype());

account.setBalance(Double.valueOf("1.0"));

// account done

account.setCustomer(customer); //建立从表与主表的联系！

customer.getAccounts().add(account); // account与主表建立关系！

customerDAO.addCustomer(customer); // 调用被封装的接口！数据此时将被级联添加的数据库的两个表中！

}

四、web层的实现，首先web层有两个action,AddPersonAction添加新用户的action，ShowListAction列表分页的action

1.AddPersonAction

请注意在application-context.xml中的action的配置：

在action中注入了CustomerDAOService也就是业务层。

</property>

</bean>

import java.util.HashMap;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.log4j.Logger;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

import com.test.common.hibernate.daos.Account;

import com.test.common.hibernate.daos.Customer;

import com.test.common.hibernate.daos.CustomerDAO;

import com.test.common.springwork.service.CustomerDAOService;

import com.test.common.struts.actionforms.AddPersonActionForm;

//import org.springframework.web.context.ContextLoaderListener;

/** 请按以下注释开发！！

* <p>Title: test action </p>

* <p>Description: struts action add person</p>

* <p>Company: digitalArchive</p>

* @author wangghost

* @version 1.0

public class AddPersonAction extends Action {

/**

* struts Action 与spring已整合！功能：做到级联添加新客户信息！

public AddPersonAction() {

super();

}

private static Logger log = Logger.getLogger(AddPersonAction.class);

private CustomerDAOService customerDAOService;

/**

* @return Returns the customerDAOService.

public CustomerDAOService getCustomerDAOService() {

return customerDAOService;

}

/**

* @param customerDAOService The customerDAOService to set.

public void setCustomerDAOService(CustomerDAOService customerDAOService) {

this.customerDAOService = customerDAOService;

}

/**

* @return Returns the customerDAO.

public ActionForward execute(ActionMapping mapping, ActionForm actionform,

HttpServletRequest request, HttpServletResponse response) {

String encoding = request.getCharacterEncoding();// 或取当前编码格式！

if (encoding != null && encoding.equalsIgnoreCase("utf-8"))// 如果是utf-8格式转成gb2312编码格式

response.setContentType("text/html; charset=gb2312");

if (actionform instanceof AddPersonActionForm) { // actionform装载是否是addpersonactionform

AddPersonActionForm person = (AddPersonActionForm) actionform;

String name = person.getFristname().trim()

+ person.getLastname().trim();// name 注意格式“+”

String password = person.getPassword().trim();

String accountname = person.getAccountname();

String accounttype = person.getAccounttype();

String email = person.getEmail();

String userid = person.getUserid();

java.sql.Date date = new java.sql.Date(System.currentTimeMillis());

HashMap keymap = new HashMap(); // 建立hashmap把表单域中的相应的值压进去！

keymap.put("name", name);

keymap.put("password", password);

keymap.put("accountname", accountname);

keymap.put("accounttype", accounttype);

keymap.put("email", email);

StringBuffer buffer = (StringBuffer) BlankString(keymap);

if (buffer.length() > 0) // 注意格式！

{ // “{” 请折行显示！

request.setAttribute("msg", buffer.toString()); // 如果有错误将跳转到错误收集页面！

return mapping.findForward("msg");

}

this.customerDAOService.customerService(person,userid,date);

return mapping.findForward("showlist");

}

return null;

}

/**

* 把actionForm中的validate表单的验证放到action中

* @param keymap

* @return String[]

private StringBuffer BlankString(HashMap keymap) {

StringBuffer str = new StringBuffer();

if( ( keymap.get("name") ).equals("") )

{

str.append("用户名不能为空！ ");

}

if( ( keymap.get("password") ).equals("") )

{

str.append("密码不能为空！ ");

}else

{

if( !( ( ( ( keymap.get("password") ).toString() ).length() >= 4 )

&& ( ( ( keymap.get("password") ).toString() ).length() <= 10 ) ) )

str.append("密码必须在4---10之间！ ");

}

if( ( keymap.get("accountname") ).equals("") )

{

str.append("账户名不能为空 ");

}

if( ( keymap.get("accounttype") ).equals("") )

{

str.append("账户类型不能为空 ");

}

if( ( keymap.get("email") ).equals("") )

{

str.append("邮箱不能为空 ");

}else

{

if( ( keymap.get("email").toString() ).indexOf("@") == -1 )

str.append("email 格式不对！");

}

return str;

}

2.ShowListAction功能复杂，要介绍关于分页、以及spring的HibernateCallback()回调功能。

ShowListAction：

再来看看分页，用taglib来实现：

</property>

</bean>

import java.util.ArrayList;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.log4j.Logger;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

import com.test.common.hibernate.daos.Customer;

import com.test.common.hibernate.daos.ShowListDAO;

/**

* 请按一下注释开发！！

* <p>

* Title: list person info action

* </p>

* <p>

* Description: struts action show the person info

* </p>

* <p>

* </p>

* <p>

* Company: digitalArchive

* </p>

* @author wangghost

* @version 1.0

public class ShowListAction extends Action {

/**

* super

public ShowListAction() {

super();

}

private static Logger log = Logger.getLogger(AddPersonAction.class);

private ShowListDAO showListDAO;

/**

* @return Returns the showListDAO.

public ShowListDAO getShowListDAO() {

return showListDAO;

}

/**

* @param showListDAO

* The showListDAO to set.

public void setShowListDAO(ShowListDAO showListDAO) {

this.showListDAO = showListDAO;

}

public ActionForward execute(ActionMapping mapping, ActionForm actionform,

HttpServletRequest request, HttpServletResponse response) {

String encoding = request.getCharacterEncoding();// 或取当前编码格式！

if (encoding != null && encoding.equalsIgnoreCase("utf-8"))// 如果是utf-8格式转成gb2312编码格式

response.setContentType("text/html; charset=gb2312");

ArrayList personDetailList = new ArrayList();

String _page = "1"; //当前页号

String _size = "10"; //总页数

String _choice = ""; //分页标签类型

if (request.getParameter("pageNo") != null

&& request.getParameter("pageSize") != null) {

_page = request.getParameter("pageNo");

_size = request.getParameter("pageSize");

_choice = request.getParameter("choice");

}

String total = request.getParameter("total"); // 初识化为0

if (total != null)

_page = currentPageNumber(_choice, _page, total, _size); //获取当前页号

Object[] objectList = (Object[]) showListDAO.GetPersonDetails(

new Customer(), Integer.parseInt(_size), Integer

.parseInt(_page)); //通过showlistdao接口获取总页数和结果集！

personDetailList = (ArrayList) objectList[0];

total = objectList[1].toString();

// set value of page

request.setAttribute("personDetailList",personDetailList);

request.setAttribute("pageNo",_page);

request.setAttribute("pageSize",_size);

request.setAttribute("total",total);

return mapping.findForward("showlist");

}

/**

* <p>

* Description:根据choice类型获取当前页号

* </p>

* @param choice

* @param _page

* @param _total

* @param _size

* @return

public String currentPageNumber(String choice, String _page, String _total,

String _size) {

int pageNo = Integer.parseInt(_page);

int total = Integer.parseInt(_total);

int pageSize = Integer.parseInt(_size);

// 计算总页数注意格式！

int pages = (total % pageSize == 0) ? total / pageSize : total

/ pageSize + 1;

// 根据操作,重新确定当前页号

if (choice.equals("next"))

pageNo++;

if (choice.equals("prev"))

pageNo--;

if (choice.equals("first"))

pageNo = 1;

if (choice.equals("last"))

pageNo = pages;

// 页号越界处理

if (pageNo > pages)

pageNo = pages;

if (pageNo <= 0)

pageNo = 1;

return String.valueOf(pageNo);

}

其中注入了ShowListDAO，下面介绍ShowListDAO和ShowListDAOImpl的内容：

/**

* @author wangghost

*实际的服务类接口

* 更改所生成类型注释的模板为

* 窗口 > 首选项 > Java > 代码生成 > 代码和注释

public interface ShowListDAO {

public abstract Object[] GetPersonDetails(Customer customer,int size,final int page);//分页业务方法

}

在application-context.xml中的配置：

</property>

</bean>

import java.sql.SQLException;

import java.util.ArrayList;

import java.util.Iterator;

import java.util.List;

import org.hibernate.HibernateException;

import org.hibernate.Session;

public class ShowListDAOImpl extends HibernateDaoSupport implements ShowListDAO {

/**

}

* （非 Javadoc）

* @see com.test.common.hibernate.daos.ShowListDAO#GetPersonDetails(com.test.common.hibernate.daos.Customer,

public Object[] GetPersonDetails(Customer customer, int size, final int page) {//

Object[] ob = new Object[2]; //用来获得条目数，数据记录

ArrayList list = new ArrayList();

int countList = 0;

// Account account = null;

String sql = "select count(c) from Customer c";

// getHibernateTemplate().getSessionFactory().openSession().createCriteria(Customer.class).createAlias()

countList = ((Integer) (getHibernateTemplate().find(sql)).iterator().next()).intValue(); //通过getHibernateTemplate()获取当前主表的总记录数！

final int pagesize = size; //总页数

// 启用spring hibernate回调功能实现分页

list = (ArrayList) getHibernateTemplate().execute(

new HibernateCallback() {

public Object doInHibernate(Session session)

throws HibernateException, SQLException {

ArrayList personlist = new ArrayList();

//转换sql=select * from Customer c,Account a where c.id = a.id

List list = session.createCriteria(Customer.class)

.createAlias("accounts", "a")

.setFirstResult((page - 1) * pagesize)

.setMaxResults(pagesize)

.list();

// getHibernateTemplate().flush();

// insert into java bean

for (Iterator person = list.iterator(); person.hasNext();) {//取出customer表中相应的信息

PersonDetail personDetail = new PersonDetail();

Customer customer = (Customer) person.next();

// personDetail.setBalance(String.valueOf(customer.getBalance()));

personDetail.setName(customer.getFirstName()

+ customer.getLastName());

personDetail.setEmail(customer.getEmail());

personDetail.setPassword(customer.getPassword());

personDetail.setUserid(customer.getUserId());

for (Iterator table = customer.getAccounts().iterator(); table.hasNext();) {//取出每条customer表信息对应的account表的信息

Account _account = (Account) table.next();

personDetail.setAccountname(_account

.getAccountName());

personDetail.setCreatedate(_account

.getCreateDate().toString());

personDetail.setBalance(String.valueOf(_account

.getBalance()));

personDetail.setAccounttype(_account.getType());

}

personlist.add(personDetail);

}

return personlist;

}

});

ob[0] = list.clone();

ob[1] = String.valueOf(countList);

return ob;

}

1、page.tld
