Struts、Spring、Hibernate整合开发

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

然后是JSP文件

login.jsp

[html] view
plaincopy

<%@ 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">

<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

[html] view
plaincopy

<%@ 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>

failure.jsp

[html] view
plaincopy

<%@ page language="java" contentType="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

[java] view
plaincopy

package com.zzb.action;

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;

}

}

BaseService.java

public List<BaseVO> queryAll();

}

BaseServiceImpl.java

[java] view
plaincopy

package com.zzb.service;

import java.util.List;

import com.zzb.dao.BaseDAO;

import com.zzb.vo.BaseVO;

public class BaseServiceImplimplements BaseService {

public BaseVO addVO(BaseVO vo) {

return null;

}

public boolean deleteVOById(BaseVO vo) {

return false;

}

public BaseVO getVOById(BaseVO BaseVO) {

}

public List<BaseVO> queryAll() {

return null;

}

public List<BaseVO> queryVO(BaseVO obj) {

return null;

}

}

public void updateVO(BaseVO vo) {

}

public BaseDAO getBaseDao() {

return baseDao;

}

public void setBaseDao(BaseDAO baseDao) {

this.baseDao = baseDao;

}

}

BaseVO.java

[java] view
plaincopy

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

[java] view
plaincopy

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。
