Struts2+Spring3+Hibernate3配置全过程

最近，使用ssh框架实现了一个简单的用户登录过程，麻雀虽小，五脏俱全。jdk使用的版本是1.6。从头开始说，首先从他们各自的官网上下载sdk开发包，我下的版本是：hibernate-3.5.5、spring-3.1.0.M1、struts-2.2.1.1。如下图所示：

比较大，里边东西很多，文档、源码、jar包、例子啥都有。我们开发时，只需要几个必需的jar包（总共大约30个左右）。各位如果嫌大不想下载，可以直接下载我的项目，从项目中\WEB-INF\lib目录下拷贝就行了。所需的Jar包如图所示：

下面是各个jar包的来源：

Hibernate：

• antlr-2.7.6.jar
• commons-collections-3.1.jar
• dom4j-1.6.1.jar
• hibernate3.jar
• javassist-3.9.0.GA.jar
• jta-1.1.jar
• slf4j-api-1.5.8.jar
• slf4j-nop-1.5.8.jar（这个jar包需要从slf4j框架中找）

Spring：

• commons-dbcp.jar
• commons-logging-1.0.4.jar
• commons-pool.jar
• org.springframework.asm-3.1.0.M1.jar
• org.springframework.beans-3.1.0.M1.jar
• org.springframework.context-3.1.0.M1.jar
• org.springframework.core-3.1.0.M1.jar
• org.springframework.expression-3.1.0.M1.jar
• org.springframework.jdbc-3.1.0.M1.jar
• org.springframework.transaction-3.1.0.M1.jar
• org.springframework.web-3.1.0.M1.jar

Struts：

• aopalliance-1.0.jar
• commons-fileupload-1.2.1.jar
• commons-io-1.3.2.jar
• commons-logging-1.0.4.jar
• freemarker-2.3.16.jar
• javassist-3.7.ga.jar
• ognl-3.0.jar
• struts2-core-2.2.1.1.jar
• struts2-spring-plugin-2.2.1.1.jar
• xwork-core-2.2.1.1.jar

好，下面准备开始。

打开eclipse，新建一个web，项目取名SSH1，结构如下图所示，建立根据如图所示建立相应的包、文件夹、java文件、jsp文件、xml文件，最后将需要的jar文件拷贝到\WEB-INF\lib下。

先说配置文件：

web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> <init-param> <param-name>config</param-name> <param-value>struts-default.xml,struts-plugin.xml,../struts-conf/struts.xml </param-value> </init-param> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-conf/spring*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <display-name>SSH1</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> <welcome-file>login.jsp</welcome-file> </welcome-file-list> </web-app>

spring-core.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> </bean> <tx:annotation-driven transaction-manager="transactionManager" /> </beans>

spring-conf.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="loginAction" class="com.zzb.action.LoginAction" scope="prototype"> <property name="baseService" ref="baseService" /> </bean> <bean id="baseService" class="com.zzb.service.BaseServiceImpl" > <property name="baseDao" ref="baseDAO" /> </bean> <bean id="baseDAO" class="com.zzb.dao.BaseDAOImpl" scope="prototype"> <property name="sessionFactory" ref="sessionFactory" /> </bean> </beans>

Hibernate.cfg.xml

<?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> <!-- Database connection settings --> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://localhost:3306/hibernate2</property> <property name="connection.username">root</property> <property name="connection.password">123</property> <!-- JDBC connection pool (use the built-in) --> <property name="connection.pool_size">2</property> <!-- SQL dialect --> <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property> <!-- Enable Hibernate's current session context --> <property name="current_session_context_class">org.hibernate.context.ManagedSessionContext</property> <!-- Disable the second-level cache --> <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property> <!-- Echo all executed SQL to stdout --> <property name="show_sql">true</property> <!-- Drop and re-create the database schema on startup --> <property name="hbm2ddl.auto">update</property> <mapping resource="com/zzb/vo/User.hbm.xml"/> </session-factory> </hibernate-configuration>

User.hbm.xml

<?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 package="com.zzb.vo"> <class name="User" table="user"> <id name="id"> <generator class="native"/> </id> <property name="name" column="name"/> <property name="date" column="date"/> </class> </hibernate-mapping>

然后是JSP文件

login.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <%@taglib prefix="s" uri="/struts-tags"%> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <s:form action="login.action" namespace=""> <s:textfield key="username"/> <s:password key="password" /> <s:submit/> </s:form> </body> </html>

success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> success成功</br> username:${requestScope.username}</br> password:${requestScope.password}</br> </body> </html>

failure.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> failure失败</br> username:${requestScope.username}</br> password:${requestScope.password}</br> </body> </html>

最后是java源文件

LoginAction.java

package com.zzb.action; import com.zzb.service.BaseService; import com.opensymphony.xwork2.ActionSupport; import com.zzb.vo.User; public class LoginActionextends ActionSupport { private String username; private String password; private BaseService baseService; public String execute(){ System.out.println(username); System.out.println(password); User user =new User(); user.setId(2); user = (User) baseService.getVOById(user); System.out.println(">>>>>>>>>>>>>>>>>>"+user.getName()); System.out.println(">>>>>>>>>>>>>>>>>>"+user.getDate()); String result = "success"; return result; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public BaseService getBaseService() { return baseService; } public void setBaseService(BaseService baseService) { this.baseService = baseService; } }

BaseDAO.java

package com.zzb.dao; import java.util.List; import com.zzb.vo.BaseVO; public interface BaseDAO { public BaseVO addVO(BaseVO vo); public boolean deleteVOById(BaseVO vo); public void updateVO(BaseVO vo); public BaseVO getVOById(BaseVO id); public List<BaseVO> queryVO(BaseVO obj); public List<BaseVO> queryVOBySQL(String sql); public List<BaseVO> queryAll(); }

BaseDAOImpl.java

package com.zzb.dao; import java.util.List; import org.hibernate.SessionFactory; import com.zzb.vo.BaseVO; public class BaseDAOImplimplements BaseDAO { private SessionFactory sessionFactory; public BaseVO addVO(BaseVO vo) { return null; } public boolean deleteVOById(BaseVO vo) { return false; } public BaseVO getVOById(BaseVO vo) { assert(vo.getId()!=null); BaseVO result = (BaseVO)sessionFactory.openSession().load(vo.getClass(), vo.getId()); return result; } public List<BaseVO> queryAll() { return null; } public List<BaseVO> queryVO(BaseVO vo) { return null; } public List<BaseVO> queryVOBySQL(String sql) { return null; } public void updateVO(BaseVO vo) { } public SessionFactory getSessionFactory() { return sessionFactory; } public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } }

BaseService.java

package com.zzb.service; import java.util.List; import com.zzb.vo.BaseVO; public interface BaseService { public BaseVO addVO(BaseVO vo); public boolean deleteVOById(BaseVO vo); public void updateVO(BaseVO vo); public BaseVO getVOById(BaseVO user); public List<BaseVO> queryVO(BaseVO obj); public List<BaseVO> queryVOBySQL(String sql); public List<BaseVO> queryAll(); }

BaseServiceImpl.java

package com.zzb.service; import java.util.List; import com.zzb.dao.BaseDAO; import com.zzb.vo.BaseVO; public class BaseServiceImplimplements BaseService { BaseDAO baseDao; public BaseVO addVO(BaseVO vo) { return null; } public boolean deleteVOById(BaseVO vo) { return false; } public BaseVO getVOById(BaseVO BaseVO) { return (BaseVO)baseDao.getVOById(BaseVO); } public List<BaseVO> queryAll() { return null; } public List<BaseVO> queryVO(BaseVO obj) { return null; } public List<BaseVO> queryVOBySQL(String sql) { return null; } public void updateVO(BaseVO vo) { } public BaseDAO getBaseDao() { return baseDao; } public void setBaseDao(BaseDAO baseDao) { this.baseDao = baseDao; } }

BaseVO.java

package com.zzb.vo; import java.io.Serializable; public class BaseVOimplements Serializable { private Integer id; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } }

User.java

package com.zzb.vo; import java.util.Date; public class Userextends BaseVO{ private String name; private Date date; public String getName() { return name; } public void setName(String name) { this.name = name; } public Date getDate() { return date; } public void setDate(Date date) { this.date = date; } }

以上就是全部代码，虽然有些简单，很多类方法都没有写，但已经包含了了ssh框架全部的配置过程。

代码都完成了，然后就可以部署了，我使用的服务器是tomcat6.0，数据库是mysql5.0。部署时不要忘了将数据库的驱动mysql-connector-java-5.0.3-bin.jar考到tomcat目录lib下。部署完成后，启动，访问http://127.0.0.1:8080/SSH1，如果出来成功页面，就成功了。好，就这么多。各位如果有什么问题可以问我。
