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：

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。
