Struts2,Spring,Hibernate整合例子一个 收藏
1.建立web项目
2.在web.xml 配置 struts2，和 spring ，
<!-- 配置Struts2 -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher(struts的过滤器)
</filter-class>
</filter>
<filter-mapping>（加载struts2）
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置Spring -->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener（spring监听器）
</listener-class>
</listener>
<!-- 查找spring配置文件 -->
<context-param>（程序从此处开始加载.xml 文件，并执行）
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:*.xml</param-value>
</context-param>
3.在src根目录下创建struts.xml文件
<include file="struts-default.xml"/>固定格式，用到此包
4.在src根目录 创建hibernate.cfg.xml文件
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd ">
<hibernate-configuration>
<session-factory>
<!-- 基本配置 -->
<property name="dialect">
org.hibernate.dialect.Oracle9Dialect
</property>
<property name="show_sql">false</property>
<property name="format_sql">true</property>
<property name="bytecode.use_reflection_optimizer">true</property>
<property name="max_fetch_depth">2</property>
<property name="default_batch_fetch_size">8</property>
<property name="jdbc.batch_size">20</property>
</session-factory>
</hibernate-configuration>
系统给的文件 只需要拷贝，都是一些数据库库的基本配置
5.在src根目录 拷贝struts.properties文件
struts.objectFactory = spring 该项是告诉系统 用spring来 控制hibernate和Action
struts.action.extension=action 告诉系统访问时以什么结尾。可以改为: do 例如：login.do ,此处为:login.action
6.在src根目录下 创建applicationContext.xml
配置数据源
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value ="oracle.jdbc.driver.OracleDriver"/> <!--jtds<property name="driverClassName" value ="net.sourceforge.jtds.jdbc.Driver"/>-->
<property name="url" value ="jdbc:oracle:thin:@192.168.0.95:1521:ZXDB2"/> <!--<property name="url" value="jdbc:jtds:sqlserver://localhost:1455/demo"></property>-->
<property name="username" value ="test"/>
<property name="password" value ="test"/>
</bean>
创建sessionFactory 工厂
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="dataSource"/>
</property>
<property name="configLocation">
<value type="org.springframework.core.io.Resource">classpath:hibernate.cfg.xml</value>
</property>
</bean>
考来用
7.创建 实体类
就是写一个bean 含有get/set 方法
8.在实体类所在的目录下，写一个 类名.hbm.xml文件，在配置文件中添加属性
<?xml version="1.0" encoding="utf-8"?>
<!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.zx.test.model.User" table="LB_USER">
<id name="id" type="java.lang.Long">主键的类型为Long
<column name="ID"/>
<generator class="sequence">
<param name="sequence">SEQ_LB_USER</param>指定主键生成方式，必须在pl/sql创建主键生成方式
</generator>
</id>
<property name="name" type="java.lang.String">
<column name="name" length="20"/>
</property>
<property name="age" type="java.lang.Integer">
<column name="age" length="2"/>
</property>
<property name="password" type="java.lang.String">
<column name="password" length="20"/>
</property>
所有属性的name 必须与 bean中的set后的名称一样
</class>
</hibernate-mapping>
9.创建一个 Dao 实现操作方法
10 创建 service 调用 Dao中的方法
11.创建 Action 将service的得到的user 加到Action中
12.在applicationContext.xml 中配置
将userDao注入到sessionFactory中
将userService 注入到UserDao中
将userAction 注入到 userService中
13.在struts.xml中 配置Action
<package name="user" extends="struts-default（固定与include对应）" namespace="/use（访问时路径）r">
<action name="userAdd（访问时路径）" class="userAction" method="userAdd">
<result name="success">/userShow.jsp</result>
</action>
</package>
此处配置了访问时的路径：/user/userAdd
14.将8中的配置文件 加入到 4 中
<mapping resource="com/zx/test/model/User.hbm.xml" />
引用配置文件
15.写jsp页面 表单提交到 Action
9.10.11：是 Action 调用 Service ，Service调用 Dao 也是分层的体现
Web.xml 是web工程的配置文件
ApplicationContext 是 spring的配置文件
Hibernate.hbm.xml 是hibernate的配置文件
建表是 注意创建主键时 name 为 表明
项目目录：
User.java
package com.zx.test.model;
public class User {
private Long id;
private String name;
private Integer age;
private String password;
// get/set方法
}
User.hbm.xml
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

<hibernate-mapping>
<class name="com.zx.test.model.User" table="LB_USER">
<id name="id" type="java.lang.Long">
<column name="ID"/>
<generator class="sequence">
<param name="sequence">SEQ_LB_USER</param>
</generator>
</id>
<property name="name" type="java.lang.String">
<column name="name" length="20"/>
</property>
<property name="age" type="java.lang.Integer">
<column name="age" length="2"/>
</property>
<property name="password" type="java.lang.String">
<column name="password" length="20"/>
</property>
</class>
</hibernate-mapping>
UserDao.java
package com.zx.test.dao;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.zx.test.model.User;
public class UserDao extends HibernateDaoSupport {
/**
* 保存user
* @param user
*/
public void saveUser(User user){
// spring自带方法 保存
this.getHibernateTemplate().save(user);
}
//update, delete ,findAll 方法同上，省略！
}
UserService.java
package com.zx.test.service;
import com.zx.test.dao.UserDao;
import com.zx.test.model.User;
public class UserService {
private UserDao userDao;
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
public void saveUser(User user){
userDao.saveUser(user);
}
// 在此处添加业务逻辑方法；
}
UserAction.java
package com.zx.test.action;
import com.opensymphony.xwork2.ActionSupport;
import com.zx.test.model.User;
import com.zx.test.service.UserService;
public class UserAction extends ActionSupport {
private User user;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
private UserService userService ;
public void setUserService(UserService userService) {
this.userService = userService;
}
public String userAdd(){
this.userService.saveUser(user);
return SUCCESS;
}
//添加action方法
}

age:<input type="text" name="user.age"><br>
<input type="submit" value="submit"> <input type="reset" value="reset">

userShow.jsp
在第一行添加 struts2 的标签
即：<%@ taglib prefix="s" uri="/struts-tags" %>
<body>
userName: <s:property value="user.name"/><br>
password:<s:property value="user.password"/><br>
age:<s:property value="user.age"/>
</body>
struts.properties 文件可要可无！（可以自己配置）
