Spring 一二事（8） - annotation 形式的 MVC

 <!--
            component:把一个类放入到spring容器中,该类就是一个component
            在base-package指定的包及子包下扫描所有的类
     -->
     <context:component-scan base-package="com.lee.spring012.scan.mvc.annotation"></context:component-scan>

IStuDAO.java

 package com.lee.spring012.scan.mvc.annotation;

 public interface IStuDAO {
     public void saveStu();
 }

IStuService.java

 package com.lee.spring012.scan.mvc.annotation;

 public interface IStuService {
     public void saveStu();
 }

PersonAction.java

 package com.lee.spring012.scan.mvc.annotation;

 import javax.annotation.Resource;

 import org.springframework.context.annotation.Scope;
 import org.springframework.stereotype.Controller;

 @Controller
 @Scope("prototype")        // action为多例
 public class PersonAction {

     @Resource
     public IStuService stuServiceImpl;

     public void displaySave() {
         System.out.println("mvc action: saving stu...");
         stuServiceImpl.saveStu();
     }

 }

StuDAOImpl.java

 package com.lee.spring012.scan.mvc.annotation;

 import org.springframework.stereotype.Repository;

 @Repository
 public class StuDAOImpl implements IStuDAO {

     @Override
     public void saveStu() {
         System.out.println("mvc dao: saving stu...");
     }

 }

StuServiceImpl.java

 package com.lee.spring012.scan.mvc.annotation;

 import javax.annotation.Resource;

 import org.springframework.stereotype.Service;

 @Service
 public class StuServiceImpl implements IStuService {

     @Resource
     public IStuDAO stuDAOImpl;

     @Override
     public void saveStu() {
         System.out.println("mvc service: saving stu...");
         stuDAOImpl.saveStu();
     }

 }

测试

 package com.lee.spring012.scan.mvc.annotation;

 import org.junit.Test;
 import org.springframework.context.ApplicationContext;
 import org.springframework.context.support.ClassPathXmlApplicationContext;

 public class PersonTest {

     @Test
     public void testPersonAction() {
         ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-scan-mvc.xml");
         PersonAction person = (PersonAction)context.getBean("personAction");
         person.displaySave();
     }

 }
