这里定义了spring配置文件的位置；
struts的配置信息中，除了最后一个是自定义的文件，其他两个都是再引入的jar包中就包含的，有需要可以把前面两个也换成自己定义的配置文件的路径；
<!-- Spring配置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- struts配置 -->
<filter>
<filter-name>struts</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
<init-param>
<param-name>config</param-name>
<param-value>struts-default.xml,struts-plugin.xml,struts/struts.xml</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
主要定义了要扫描的包，因为把struts的Action创建交给了spring来处理，所以需要扫描包
<?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:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
">
<!-- 自动扫描dao和service包(自动注入) -->
<context:component-scan base-package="cn.com.wyl.examples.struts" />
</beans>
在这个配置文件中，引入了一个action的配置文件，action会在后面贴出来
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.action.extension" value="do"/>
<include file="struts/hello/hello-config.xml"/>
</struts>
使用@Component将这个实体注入到spring容器
import cn.com.wyl.examples.struts.entity.User;
import cn.com.wyl.examples.struts.service.HelloService;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.json.JSONUtil;
import org.springframework.stereotype.Component;
import javax.annotation.Resource;
@Component(value = "helloAction")
public class HelloAction extends ActionSupport {
private User user;
@Resource
private HelloService helloService;
public String sayHello() {
this.user = new User();
this.user.setUsername(helloService.sayHello());
return "sayHello";
}
public String helloPage(){
return "helloPage";
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
public class User {
private String username;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
public interface HelloService {
String sayHello();
}
import cn.com.wyl.examples.struts.service.HelloService;
import org.springframework.stereotype.Service;
@Service
public class HelloServiceImpl implements HelloService {
@Override
public String sayHello() {
return "wenyoulong";
}
}
配置文件中action的class属性，就是action在spring容器中的名称
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.devMode" value="true" />
<package name="helloAction" extends="struts-default,json-default" namespace="/myHello" >
<action name="helloWorld" class="helloAction">
<result name="helloPage">/WEB-INF/hello.jsp</result>
<result name="sayHello" type="json">
<param name="root">user</param>
</result>
</action>
</package>
</struts>
到此，将项目启动就完成整合了，可通过如下路径访问这个程序。
/myHello/helloWorld!helloPage.do
/myHello/helloWorld!sayHello.do
