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">

</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">

</body>
</html>
failure.jsp
<%@ page language="java" contentType="text/html; charset=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>
failure失败</br>
username:${requestScope.username}</br>
password:${requestScope.password}</br>
</body>
</html>
最后是java源文件

}
}
BaseVO.java
package com.zzb.vo;
import java.io.Serializable;
public class BaseVOimplements Serializable {
private Integer id;
public Integer getId() {

}
User.java

public void setDate(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。
