SSH框架搭建登录实例

最近在做网上商城的项目，是基于SSH2框架来做的，顺便学了一下搭建SSH2框架，今天就分享给大家。
我用的SSH2版本为：struts-2.3.15.3+Spring3.2+hibernate-3.6.10

1.引入jar包

Struts2：
struts2-core-2.3.15.3.jar
asm-3.3jar
asm-common-3.3jar
asm-tree-3.3jar
xwork-core-2.3.15.3.3.jar

dom4j-1.6.1.jar
slf4j-api-1.6.1.jar
javassist-3.12.0.GA.jar
jta-1.1.jar

2.配置

web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
 <!-- 配置Spring的核心监听器 -->
 <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>

 <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
 </context-param>

 <!-- 配置Struts2的核心过滤器 -->
 <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>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
 </filter-mapping>
  <display-name></display-name> 

  <!--设置默认的访问页，访问网址http://localhost:8080/SSHdemo时可以自动跳转到login.jsp页面 -->
  <welcome-file-list>
    <welcome-file>login.jsp</welcome-file>
  </welcome-file-list>
</web-app>

注意：在webroot节点下建立一个login.jsp才能找到。

Struts.xml配置

<?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="false" />

    <!-- package：用来统一管理action --> 
    <package name="SSHdemo" extends="struts-default" namespace="/">
        <!-- 用户模块的Action -->
        <action name="user_*" class="userAction" method="{1}">
            <result name="loginSuccess">index.jsp</result>              
        </action>

    </package>
</struts>

注意：action标签的class属性，与spring结合后要写成spring中bean的名称name。

applicationContext.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:context="http://www.springframework.org/schema/context" 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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">

    </bean>

    <!-- 开启注解事务 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>

    <!-- Action的配置 ===========================-->
    <!-- 用户模块的Action -->
    <bean id="userAction" class="cn.itcast.shop.user.action.UserAction" scope="prototype">
        <property name="userService" ref="userService"></property>

    <bean id="userService" class="cn.itcast.shop.user.service.UserService">
        <property name="userDao" ref="userDao"/>
    </bean>


    <!-- Dao的配置 ===========================-->
    <bean id="userDao" class="cn.itcast.shop.user.dao.UserDao">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

</beans>

3.登录实例编写

Action层：UserAction

/** * 用户模块Action的类 * * @author xiao * */
public class UserAction extends ActionSupport implements ModelDriven<User> {
    //模型驱动使用的对象
    private User user=new User();
    public User getModel(){
        return user;
    }

    // 注入UserService
    private UserService userService;

    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    /** * 登陆 */
    public String login(){
        User existUser=userService.login(user);
        if(existUser==null){
            //登陆失败
            this.addActionError("登陆失败：用户名或密码错误用户未激活！");
            return LOGIN;
        }else {
            //登陆成功
            //将用户的信息存入session中
            ServletActionContext.getRequest().getSession().setAttribute("existUser", existUser);
            //页面跳转
            return "loginSuccess";
        }

    }

}

service层：UserService

/** * @ClassName: UserService * @Description: 登录用户service层 * @author 宋笑 * @date 2015-10-8 下午03:34:45 * */
@Transactional
public class UserService {
    //对UserDao的注入
    private UserDao userDao;

    /** * @param userDao the userDao to set */
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }

    //登录方法
    public User login(User user) {
        // TODO Auto-generated method stub
        return userDao.login(user);
    }


}

DAO层：UserDao

/** * @ClassName: UserDao * @Description: 用户管理持久层 * @author 宋笑 * @date 2015-10-8 下午03:36:03 * */
public class UserDao extends HibernateDaoSupport{
    //用户登陆的方法
    public User login(User user) {
        // TODO Auto-generated method stub
        String hql="from User where username=? and password=? and state=?";
        List<User> list=this.getHibernateTemplate().find(hql,user.getUsername(),user.getPassword(),1);
        if(list!=null&&list.size()>0){
            return list.get(0);
        }

        return null;
    }
}

vo层：User

/** * @ClassName: User * @Description: 用户实体层 * @author 宋笑 * @date 2015-10-8 下午03:36:33 * */
public class User {
    private String username;
    private String password;

    /** * @return the username */
    public String getUsername() {
        return username;
    }
    /** * @param username the username to set */
    public void setUsername(String username) {
        this.username = username;
    }
    /** * @return the password */
    public String getPassword() {
        return password;
    }
    /** * @param password the password to set */
    public void setPassword(String password) {
        this.password = password;
    }

}

学会自己搭框架，看着别人搭总觉得很简单，但是自己亲自动手试一下中间会出现各种各样的错，解决完以后收获很多。还在学习阶段，这个例子只是一个简单的搭建，后面还有很多配置需要深入学习！最后附上源码下载地址：http://download.csdn.net/detail/u010539352/9194747
