首先，Spring和Struts需要整合到java web当中去，因此需要在web.xml中对struts和spring进行注册
其次，Spring和Struts整合的关键是：Struts中的action类交由Spring的IOC容器创建。
(1)添加jar包
(2)配置
(3)action代码准备
(4)注册action(分别在Spring和Struts中)
(5)添加JSP页面
1、添加jar包
引入struts jar包和spring web的jar包
struts的jar包（struts-2.3.29） commons-fileupload-1.3.1.jar commons-io-2.2.jar commons-lang3-3.2.jar commons-logging-1.1.3.jar freemarker-2.3.22.jar javassist-3.11.0.GA.jar ognl-3.0.17.jar struts2-core-2.3.29.jar xwork-core-2.3.29.jar |
spring-web的jar包 spring-web-3.2.5.RELEASE.jar （属于spring） struts2-spring-plugin-2.3.29.jar （属于struts2） |
2、配置
2.1、在web.xml中注册Struts和Spring
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" 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_2_5.xsd"> <!-- 注册Spring --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 注册Struts --> <filter> <filter-name>struts</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <display-name>Tax System</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
2.2、添加struts.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <!-- 禁用动态方法访问 --> <constant name="struts.enable.DynamicMethodInvocation" value="false" /> <!-- 配置成开发模式 --> <constant name="struts.devMode" value="true" /> <!-- 配置拓展名为action --> <constant name="struts.action.extention" value="action" /> <!-- 把主题配置成simple --> <constant name="struts.ui.theme" value="simple" /> <!-- 设置创建对象的工厂 --> <constant name="struts.objectFactory" value="spring" /> <!-- <package name="default" namespace="/" extends="struts-default"> <action name="" class=""> <result name="success"></result> </action> </package> --> </struts>
3、action代码准备
package com.rk.test.action;
import java.util.Map;
import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.rk.test.entity.Person;
import com.rk.test.service.PersonService;
public class PersonAction extends ActionSupport {
private PersonService personService;
public void setPersonService(PersonService personService) {
this.personService = personService;
}
public String findById() throws Exception {
String id = "4028d081564ba79401564ba7968e0000";
Person p = personService.findById(id);
ActionContext context = ActionContext.getContext();
Map<String,Object> request = (Map<String, Object>) context.get("request");
request.put("person", p);
return Action.SUCCESS;
}
}4、注册action(分别在Spring和Struts中)
4.1、在spring中注册action类
将action类注册到bean-action.xml文件中。注意：action注册要使用scope="prototype"。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <bean id="personAction" class="com.rk.test.action.PersonAction" scope="prototype"> <property name="personService" ref="personService"></property> </bean> </beans>
将bean-action.xml注册到applicationContext.xml文件中
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <import resource="classpath:bean-base.xml"/> <import resource="classpath:com/rk/*/config/bean-*.xml"/> </beans>
其实，我们并没有修改applictionContext.xml的内容，是因为下面这句
<import resource="classpath:com/rk/*/config/bean-*.xml"/>
因为它使用了“*”号来匹配
4.2、在struts中注册action类
将action类注册到struts-test.xml文件中
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="test_package" namespace="/test" extends="struts-default">
<action name="psn_*" class="personAction" method="{1}">
<result name="success">/WEB-INF/jsp/test/success.jsp</result>
</action>
</package>
</struts>将struts-test.xml文件注册到struts.xml文件中
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <!-- 禁用动态方法访问 --> <constant name="struts.enable.DynamicMethodInvocation" value="false" /> <!-- 配置成开发模式 --> <constant name="struts.devMode" value="true" /> <!-- 配置拓展名为action --> <constant name="struts.action.extention" value="action" /> <!-- 把主题配置成simple --> <constant name="struts.ui.theme" value="simple" /> <!-- 设置创建对象的工厂 --> <constant name="struts.objectFactory" value="spring" /> <include file="com/rk/test/config/struts-test.xml"/> <!-- <package name="default" namespace="/" extends="struts-default"> <action name="" class=""> <result name="success"></result> </action> </package> --> </struts>
重点是添加了下面这一句
<include file="com/rk/test/config/struts-test.xml"/>
5、添加JSP页面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@taglib uri="/struts-tags" prefix="s" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title></title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> </head> <body> <table border="1"> <tr> <td>ID:</td> <td> <s:property value="#request.person.pId"/> </td> </tr> <tr> <td>姓名：</td> <td> <s:property value="#request.person.pName"/> </td> </tr> <tr> <td>版本：</td> <td> <s:property value="#request.person.pVersion"/> </td> </tr> </table> </body> </html>
