Spring整合Struts2

①导入Struts2 jar包

②在web.xml文件中创建过滤器

<?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>    
  
  <!-- 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>
  
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

③创建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>

    <constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <constant name="struts.devMode" value="true" />

    <package name="default" namespace="/" extends="struts-default">
        
        <!--  
            Spring 整合 Struts2 时, 在 Struts2 中配置的 Spring 的 Action 的 class 需要指向 IOC 容器中该 bean 的 id
        -->
        <action name="person-save" class="personAction">
            <result>/success.jsp</result>
        </action>
        
    </package>

</struts>

④创建PersonService类

public class PersonService {
    
    public void save(){
        System.out.println("person's save.....");
    }

}

⑤创建PersonAction类

import com.atguigu.spring.struts.service.PersonService;

public class PersonAction {
    
    private PersonService personService;
    
    public void setPersonService(PersonService personService) {
        this.personService = personService;
    }
    
    public String execute(){
        System.out.println("execute.....");
        return "SUCCESS";
    }

}

⑥导入Spring的jar包

⑦创建applicationContext.xml文件

<?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:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    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-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
    
    <bean id="person" class="com.atguigu.spring.struts.beans.Person">
        <property name="username" value="spring"></property>
    </bean>
    
    <bean id="personService" class="com.atguigu.spring.struts.service.PersonService"></bean>
    
    <!-- 注意在IOC容器中配置Struts2的Action时组要配置scope属性 -->
    <bean id="personAction" class="com.atguigu.spring.struts.actions.PersonAction" scope="prototype">
        <property name="personService" ref="personService"></property>
    </bean>

</beans>

⑧导入一个jar包——struts2-spring-plugin-2.3.15.3.jar

OK!
