第一步、导包(特别注意的是要有这三个jar包)
第二步、新建applicationContext.xml+新建struts.xml文件
第三步、在web.xml文件中
1、使得applicationContext.xml资源属性
2、让web资源项目可以访问ioc容器
3、配置拦截器
<?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>
<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>
<!-- 拦截器设置 -->
<!-- 配置 Struts2 的 Filter -->
<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>
</web-app>
第四步、创建一个普通类和一个请求Action类
Person.java
package cn.com.beans;
public class Person {
// 这个类存在的意义,在Spring的配置文件中被初始化,然后IOC容器调用,
private String name;
public void setName(String name) {
this.name = name;
}
public void hello(){
System.out.println("my name is:"+name);
}
}
PersonSErvice.java
package cn.com.service;
import cn.com.beans.Person;
public class PersonService {
private Person pp;
public void setPp(Person pp) {
this.pp = pp;
}
public String save(){
System.out.println("PersonService's save....");
pp.hello();
return "success";
}
}
applicationContext.xml
一定要有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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
<bean class="cn.com.beans.Person" id="person">
<property name="name" value="atguigu"></property>
</bean>
<bean class="cn.com.service.PersonService" id="personService" scope="prototype">
<property name="pp" ref="person"></property>
</bean>
</beans>
struts.xml
注意,这里的class="是applicationContext.xml里面bean对应类的名称"
<?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>
<constant name="struts.action.extension" value="do,action,kk"></constant>
<package name="tjn" extends="struts-default">
<action name="person_save" class="personService" method="save">
<result name="success">/success.jsp</result>
</action>
</package>
</struts>
测试页面
<body>
<a href="person_save.action">Spring整合Struts2的最终版本</a>
</body>
再新建一个success.jsp
里面随便写内容作一个识别的页面
结果如下
