SSH-spring3.2与struts2.0整合小例

spring与struts整合

一 新建web Project 

二 导入spring与struts所需包

struts2-spring-plugin-2.1.8.jar是struts2、spring整合的关键!

SSH所需包下载地址：

spring包下载：http://repo.springsource.org/libs-release-local/org/springframework/spring/    点击打开链接

struts包下载：http://struts.apache.org/download.cgi    点击打开链接

hibernate包下载：http://sourceforge.mirrorservice.org/h/project/hi/hibernate/     点击打开链接

三 工程目录

四 程序部分

1.定义一个登录验证接口

package server;

public interface MyServer {
public abstract boolean LoginValid(String name,String password);
}

2.实现MyServer接口

package server;

public class MyServerImpl implements MyServer{

@Override
public boolean LoginValid(String username, String password) {
if(username.equals("city") && password.equals("123")){
return true;
}
return false;
}

}

3.业务代码LoginAction，演示登陆

package action;

import com.opensymphony.xwork2.Action;

import server.MyServer;

public class LoginAction implements Action{
private String username; //与login.jsp页面上保持一致，否则接受不到报空
private String password;
private MyServer ms;
private String tip; //在jsp页面展示出来

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 MyServer getMs() {
return ms;
}
public void setMs(MyServer ms) {
this.ms = ms;
}

public String getTip() {
return tip;
}
public void setTip(String tip) {
this.tip = tip;
}
@Override
public String execute() throws Exception {
if(ms.LoginValid(getUsername(), getPassword())){
setTip("success access!");
return "success";
}
return "fail";
}
}

五 配置文件

1.spring配置文件。在src目录下新建一个applicationContext.xml文件，配置如下：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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-3.2.xsd">

<bean name="myServer" class="server.MyServerImpl"></bean>
<bean name="loginAction" class="action.LoginAction" scope="prototype">
<property name="ms" ref="myServer"></property>
</bean>

</beans>

依赖注入：MyServerImpl的对象引用myServer被注入给LoginAction类的属性ms，这样ms就可以使用myServer的方法。

2.struts配置文件。在src目录下新建struts.xml文件，配置如下

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

<!-- 将Action的创建交给spring来管理 -->
<constant name="struts.objectFactory" value="spring" />

<package name="login"  extends="struts-default">
<action name="loginPro" class="loginAction">
<result name="success">/success.jsp</result>
<result name="fail">/fail.jsp</result>
</action>
</package>
</struts>

注意struts.xml文件中action的class属性，不是一个类，而是spring配置中bean的id，属性由spring来注入!

3.修改wel.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
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_3_0.xsd"> <display-name></display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!--配置applicaContext.xml的路径-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<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>
</filter-mapping>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

</web-app>

applicaContext.xml的路径是可以变更的，只要在<param-value>那里配上它的路径即可。

4.webRoot目录下新建login.jsp、success.jsp和fail.jsp

(1)login.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="GB18030"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!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>登陆</title>
</head>
<body>
<form action="loginPro" method="post">
<table>
<caption>用户登录</caption>
<tr>
<td>用户名：</td>
<td><input type="text" name="username"/></td>
</tr>
<tr>
<td>密码：</td>
<td><input type="text" name="password"/></td>
</tr>
<tr>
<td><input value="提交" type="submit"/></td>
<td><input value="重置" type="reset"/></td>
</tr>
</table>
</form>
</body>
</html>

(2)success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="GB18030"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!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>
<b>这是欢迎页面。</b><br>
<s:property value="tip" />
</body>
</html>

(3)fail.sjsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="GB18030"%>
<!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>
操作失败！<br>
<img src="images/404.jpg" alt="404" style="position:absolute; left:300px; top:100px; "></img>
</body>
</html>
