一、准备struts2+spring+hibernate所须要的jar包:
二、搭建struts2环境
<filter>
<filter-name>Struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>Struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>package com.zhouxiang.action;
import com.opensymphony.xwork2.ActionSupport;
import com.zhouxiang.service.LoginService;
public class LoginAction extends ActionSupport {
private String username;
private String password;
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 String Login() {
return "Login";
}
public String LoginTest() {
if (username!=null&&password!=null)) {
return "Success";
} else {
return "faliure";
}
}
}
<?xml version="1.0" encoding="UTF-8" ?
> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default"> <!-- <default-action-ref name="index" /> --> <action name="Login" class="LoginAction" method="Login"> <result name="Login"> /Login.jsp </result> </action> <action name="LoginAction" class="LoginAction" method="LoginTest"> <result name="Success"> /LoginSuccess.jsp </result> <result name="faliure"> /LoginSuccess.jsp </result> </action> </package> <!-- Add packages here --> </struts>
三、搭建spring环境并整合struts2
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener><constant name="struts.objectFactory" value="spring" />
四、搭建hibernate环境并与spring及struts2整合
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver">
</property>
<property name="url" value="jdbc:mysql://localhost:3306/TestProject1"></property>
<property name="username" value="root"></property>
<property name="password" value="123456"></property>
</bean><bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"> </property> <property name="mappingResources"> <list> <value>com/zhouxiang/bean/User.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <value> hibernate.dialect=org.hibernate.dialect.MySQLDialect hibernate.hbm2ddl.auto=update hibernate.show_sql=true hibernate.format_sql=false </value> </property> </bean>
<bean id="userdao" class="com.zhouxiang.DaoImp.UserDaoImp" parent="basedaoimp"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="loginService" class="com.zhouxiang.service.LoginService"> <property name="userdao" ref="userdao"></property> </bean> <bean id="LoginAction" class="com.zhouxiang.action.LoginAction"> <property name="loginservice" ref="loginService"></property> </bean>
五、登录demo

{
// 使用反射技术得到T的真实类型

}
}

}
UserDao接口：
package com.zhouxiang.Dao;
import com.zhouxiang.BaseDao.BaseDao;
import com.zhouxiang.bean.User;
public interface UserDao extends BaseDao<User> {
}
UserDaoImp :
package com.zhouxiang.DaoImp;

import com.zhouxiang.bean.User;
public class UserDaoImp extends BaseDaoImp<User> implements UserDao {

六、总结
SSH的环境搭建没有什么难度。须要的仅仅是一些jar包和一些配置文件。struts+spring+hibernate整合的过程中须要注意的是引入的一些jar包及为什么使用这些jar包，这些jar包的作用是什么。当然不可缺少的另一些配置文件，如web项目初始化须要做的，怎样将spring容器增加到项目中。一集怎样将struts跟hibernate、及项目中用到的实体bean、业务逻辑bean交给spring容器管理。整个环境搭建的过程最重要的是去理解三大框架是怎样独立工作的，又是怎样衔接工作的。
