SSH环境搭建

1 开发环境

    MyEclipse 10
    JDK 1.6
    Java EE 6.0
    Tomcat 7.0.25
    Struts 2.3.4
    Spring 3.1.1
    Hibernate 3.6.10

2 为ssh做好准备

所需jar包：

3、配置struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
    "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
 <package name="user" extends="struts-default">
	<action name="login" class="loginAction">
   		<result name="success">success.jsp</result>
   		<result name="fail">fail.jsp</result>
 	</action>
 </package>
</struts>

 

4、配置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_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>weiboPortal</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
</web-app>

 5、配置applicationContext.xml

applicationContext.xml存在于WEB-INF下，同时将hibernate配置项写到applicationContext.xml中

<?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.xsd">

 <!-- 设定数据库连接池 -->
 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
  <property name="driverClassName" value="com.mysql.jdbc.Driver" />
  <property name="url" value="jdbc:mysql://localhost:3306/weibo_portal" />
  <property name="username" value="root" />
  <property name="password" value="system" />
  <property name="maxActive" value="100" />
  <property name="maxIdle" value="30" />
  <property name="maxWait" value="500" />
  <property name="defaultAutoCommit" value="true" />
 </bean>

 <!-- 设定hibernate的sessionFactory -->
 <bean id="sessionFactory"
  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  <property name="dataSource" ref="dataSource"></property>

  <property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop>
    <prop key="hibernate.show_sql">true</prop>
   </props>
  </property>

  <!-- 配置映射文件 -->
  <property name="mappingResources">
   <list>
    <value>com/huawei/pojo/UserDeveloperAccount.hbm.xml</value>
   </list>
  </property>
 </bean>
 
 <bean name="loginAction" class="com.huawei.action.UserDeveloperAccountAction"
	scope="prototype">
	<property name="userService">
           <ref bean="userDeveloperAccountService" />
       </property>
 </bean>

  <bean name="userDeveloperAccountService"
       class="com.huawei.service.UserDeveloperAccountServiceImpl">
       <property name="userDao">
           <ref bean="userDao" />
       </property>
  </bean>
  
  <bean name="userDao"
  		class="com.huawei.dao.UserDeveloperAccountDaoImpl">
  		<property name="sessionFactory">
        	<ref bean="sessionFactory" />
     	</property>
 	   </bean>
</beans>

 6、测试代码

login.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %> 

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

    <input type="submit" value="确定"/> 
</form>  
</body>  
</html>  

 fail.jsp

<%@ page contentType="text/html; charset=UTF-8" %>  
<%@ taglib prefix="s" uri="/struts-tags" %>  
<html>  
<head>     
</head>  
<body>  
<s:property value="message"/><br>  
<a href="${pageContext.request.contextPath}">返回</a>
${sessionScope.sessionUser.username }aaaaa
<s:debug></s:debug>  
</body>  
</html> 

 success.jsp

<%@ page contentType="text/html; charset=UTF-8" %>  
<%@ taglib prefix="s" uri="/struts-tags" %>  
<html>

<s:property value="message"/><br>  
<a href="${pageContext.request.contextPath}">success</a>  
<s:debug></s:debug>  
</body>  
</html> 

 Action文件：

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;

import com.huawei.base.BaseAction;
import com.huawei.pojo.UserDeveloperAccount;
import com.huawei.service.UserDeveloperAccountService;
import com.opensymphony.xwork2.ActionContext;

public class UserDeveloperAccountAction extends BaseAction {

	private static final long serialVersionUID = 1L;

	private transient UserDeveloperAccountService userService = null;

	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 UserDeveloperAccountService getUserService() {
		return userService;
	}

	public void setUserService(UserDeveloperAccountService userService) {
		this.userService = userService;
	}
	
	@Override
	public String execute() throws Exception {
		HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(
				ServletActionContext.HTTP_REQUEST);
		
		System.out.println(request.getParameter("username"));
		
		UserDeveloperAccount  user = new UserDeveloperAccount(username, password, 0);
		
		UserDeveloperAccount dbUser = this.userService.checkUserExits(user);
		if (null != dbUser) {
			getSession().put("sessionUser",dbUser);
			return "success";
		}
		return "fail";
	}
}

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.interceptor.SessionAware;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class BaseAction extends ActionSupport implements SessionAware{
	private static final long serialVersionUID = 2499104578106367603L;

	public void setSession(Map<String, Object> sessionMap) {
		
	}

	public Map<String, Object> getSession(){
		return ActionContext.getContext().getSession();
	}
	
	public HttpServletRequest getRequest(){
		return ServletActionContext.getRequest();
	}
}

 Dao文件

import com.huawei.pojo.UserDeveloperAccount;

public interface UserDeveloperAccountDao {
	/** 
     * 检查用户是否存在 
     * */  
    public UserDeveloperAccount getUserByUserIdAndUserNameExits(UserDeveloperAccount user);
}

 

package com.huawei.dao;

import java.util.List;

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

import com.huawei.pojo.UserDeveloperAccount;

public class UserDeveloperAccountDaoImpl extends HibernateDaoSupport implements UserDeveloperAccountDao {

	public final Session getCurrentSession()
    {
        Session session = this.getHibernateTemplate().getSessionFactory().openSession();
        return session;
    }
	
	public UserDeveloperAccount getUserByUserIdAndUserNameExits(
			UserDeveloperAccount user) {
		Session session = this.getCurrentSession();
		String hql = "from UserDeveloperAccount where username = " + user.getUsername();
		List query = session.createQuery(hql).list();
		if(query == null || query.size() == 0){
			return null;
		}else{
			return (UserDeveloperAccount) query.get(0);
		}
	}
}

 Service文件：

import com.huawei.pojo.UserDeveloperAccount;

public interface UserDeveloperAccountService {
	
	public UserDeveloperAccount checkUserExits(UserDeveloperAccount user) throws Exception;	

}

 

import com.huawei.dao.UserDeveloperAccountDao;
import com.huawei.pojo.UserDeveloperAccount;

public class UserDeveloperAccountServiceImpl implements UserDeveloperAccountService {

	private UserDeveloperAccountDao userDao = null;

	public UserDeveloperAccountDao getUserDao() {
		return userDao;
	}

	public void setUserDao(UserDeveloperAccountDao userDao) {
		this.userDao = userDao;
	}

	public UserDeveloperAccount checkUserExits(UserDeveloperAccount user) throws Exception {
		return this.userDao.getUserByUserIdAndUserNameExits(user);		
	}
}

 POJO文件就不提供了
