整合 Struts2 和 Spring

jar包依赖

<!-- https://mvnrepository.com/artifact/org.apache.struts/struts2-spring-plugin -->
		<dependency>
			<groupId>org.apache.struts</groupId>
			<artifactId>struts2-spring-plugin</artifactId>

添加Spring配置文件

spring-struts2.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans 
    xmlns="http://www.springframework.org/schema/beans" 
    xmlns:p="http://www.springframework.org/schema/p"

    xmlns:context="http://www.springframework.org/schema/context"

    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="

    <context:component-scan 
        base-package="ssh.day02"/>
</beans>

利用 ContextLoaderListener 初始化Spring容器:

在web.xml中配置如下：

<!-- 利用ContextLoaderListener初始化Spring容器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-*.xml</param-value>
	</context-param>

创建 控制器:

package ssh.day02;

import org.springframework.stereotype.Controller;

@Controller
public class DemoAction {
	public String execute() {
		System.out.println("Hello World!");
		return "success";
	}
}

配置 struts.xml

<!-- 利用Spring管理控制器对象 class=BeanID -->
		<action name="demo" class="demoAction">
			<result name="success">
				/WEB-INF/jsp/ok.jsp
			</result>
		</action>
