Struts2+Spring整合

Struts2和Spring整合,创建一个OA工程
1、整合struts2
1)导入strut2的jar包:commons-logging-1.0.4.jar,freemarker-2.3.8.jar,ognl- 2.6.11.jar,struts2-core-2.0.12.jar,xwork-2.06.jar。暂时导入这些jar包,到时候需要再倒入。
2)将struts.xml文件放置在OA工程的src目录下。
3)在web.xml里面配置struts2用到的核心过滤器。

Xml代码
  1. < filter >   
  2.     < filter-name > struts2 </ filter-name >   
  3.     < filter-class > org.apache.struts2.dispatcher.FilterDispatcher </ filter-class >   
  4. </ filter >   
  5. < filter-mapping >   
  6.     < filter-name > struts2 </ filter-name >   
  7.     < url-pattern > /* </ url-pattern >   
  8. </ filter-mapping >   
	<filter>
	    <filter-name>struts2</filter-name>
	    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
	</filter>
	<filter-mapping>
	    <filter-name>struts2</filter-name>
	    <url-pattern>/*</url-pattern>
	</filter-mapping>

2、整合spring
1)导入spring的jar包:spring.jar
2)将applicationContext.xml文件放置在OA工程的WEB-INF目录下。
3)在web.xml里面配置spring用到的监听器。

Xml代码
  1. < listener >   
  2.     < listener-class > org.springframework.web.context.ContextLoaderListener </ listener-class >   
  3. </ listener >   
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


4)添加struts2-spring整合的插件:struts2-spring-plugin-2.0.12.jar,如果不使用这个插件,则需要在struts.xml里面配置:

Xml代码
  1. < constant   name = "struts.objectFactory"   value = "org.apache.struts2.spring.StrutsSpringObjectFactory"   />   
<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />


3、测试struts2和spring整合对不对?
写一个jsp页面login.jsp来测试:

Html代码
  1. < %@ page  language = "java"   contentType = "text/html; charset=UTF-8"   pageEncoding = "UTF-8" % >   
  2. < %@ taglib  prefix = "s"   uri = "/struts-tags"  % >   
  3. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">   
  4. < html >   
  5. < head >   
  6. < meta   http-equiv = "Content-Type"   content = "text/html; charset=UTF-8" >   
  7. < title > Insert title here </ title >   
  8. </ head >   
  9. < body >   
  10.     < s:form   action = "Login"   method = "post" >   
  11.         < s:textfield   name = "userName"   label = "userName" > </ s:textfield >   
  12.         < s:password   name = "password"   label = "password" > </ s:password >   
  13.         < s:submit   label = "submit" > </ s:submit >   
  14.     </ s:form >   
  15. </ body >   
  16. </ html >   
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ 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>
    <s:form action="Login" method="post">
        <s:textfield name="userName" label="userName"></s:textfield>
        <s:password name="password" label="password"></s:password>
        <s:submit label="submit"></s:submit>
    </s:form>
</body>
</html>

写一个LoginAction

Java代码
  1. package  com.struts2.action;  
  2.   
  3. import  com.opensymphony.xwork2.ActionSupport;  
  4. import  com.struts2.service.LoginService;  
  5. public   class  LoginAction  extends  ActionSupport {  
  6.     private  LoginService loginService;  
  7.     private  String userName;  
  8.     private  String password;  
  9.     public   void  setLoginService(LoginService loginService) {  
  10.         this .loginService = loginService;  
  11.     }  
  12.     public  String getUserName() {  
  13.         return  userName;  
  14.     }  
  15.     public   void  setUserName(String userName) {  
  16.         this .userName = userName;  
  17.     }  
  18.     public  String getPassword() {  
  19.         return  password;  
  20.     }  
  21.     public   void  setPassword(String password) {  
  22.         this .password = password;  
  23.     }  
  24.     @Override   
  25.     public  String execute()  throws  Exception {  
  26.         if (loginService.isLogin(userName, password))  
  27.             return  SUCCESS;  
  28.         else   
  29.             return  INPUT;  
  30.     }  
  31. }  
package com.struts2.action;

import com.opensymphony.xwork2.ActionSupport;
import com.struts2.service.LoginService;
public class LoginAction extends ActionSupport {
	private LoginService loginService;
	private String userName;
	private String password;
	public void setLoginService(LoginService loginService) {
		this.loginService = loginService;
	}
	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;
	}
	@Override
	public String execute() throws Exception {
		if(loginService.isLogin(userName, password))
			return SUCCESS;
		else
			return INPUT;
	}
}

写一个Service

Java代码
  1. package  com.struts2.service;  
  2.   
  3. public   interface  LoginService {  
  4.     boolean  isLogin(String userName,String password);  
  5. }  
package com.struts2.service;

public interface LoginService {
	boolean isLogin(String userName,String password);
}


写一个Service的实现

Java代码
  1. package  com.struts2.service.impl;  
  2.   
  3. import  com.struts2.service.LoginService;  
  4. public   class  LoginServiceImpl  implements  LoginService {  
  5.   
  6.     public   boolean  isLogin(String userName, String password) {  
  7.         if ( "hello" .equals(userName) &&  "world" .equals(password))  
  8.             return   true ;  
  9.         else    
  10.             return   false ;  
  11.     }  
  12. }  
package com.struts2.service.impl;

import com.struts2.service.LoginService;
public class LoginServiceImpl implements LoginService {

	public boolean isLogin(String userName, String password) {
		if("hello".equals(userName) && "world".equals(password))
			return true;
		else 
			return false;
	}
}

在struts.xml里面配置:

Xml代码
  1. < package   name = "struts2"   extends = "struts-default" >   
  2.     < action   name = "Login"   class = "loginAction" >   
  3.         < result   name = "success" > /result.jsp </ result >   
  4.         < result   name = "input" > /login.jsp </ result >   
  5.     </ action >   
  6. </ package >   
    <package name="struts2" extends="struts-default">
        <action name="Login" class="loginAction">
            <result name="success">/result.jsp</result>
            <result name="input">/login.jsp</result>
        </action>
    </package>

在applicationContext.xml里面配置:

Xml代码
  1. < bean   id = "loginService"   class = "com.struts2.service.impl.LoginServiceImpl" > </ bean >   
  2. < bean   id = "loginAction"   class = "com.struts2.action.LoginAction"   scope = "prototype" >   
  3.     < property   name = "loginService"   ref = "loginService" > </ property >   
  4. </ bean >   
    <bean id="loginService" class="com.struts2.service.impl.LoginServiceImpl"></bean>
    <bean id="loginAction" class="com.struts2.action.LoginAction" scope="prototype">
        <property name="loginService" ref="loginService"></property>
    </bean>

启动tomcat,分别输入hello和world,提交,结果为hello和world。说明struts2和spring整合成功。
