一、接口
public interface IService {
void beanTest();
}
二、实现类
@Service("dog")
public class DogServiceImpl implements IService{
@Override
public void beanTest() {
System.out.println(" i am dog");
}
}
@Service("cat")
public class CatServiceImpl implements IService{
@Override
public void beanTest() {
System.out.println(" i am cat cat");
}
}
三、测试
package com.web.webtest;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import javax.annotation.Resource;
import java.util.List;
@SpringBootTest(classes = WebtestApplication.class)
class WebtestApplicationTests {
@Resource
List<IService> service;
//会注入 同名的dog
@Resource
IService dog;
//会注入 同名的 cat
@Resource
IService cat;
@Test
void contextLoads() {
}
/**
* i am cat cat
* i am dog
*/
@Test
void serviceTest(){
for (IService ss:service){
ss.beanTest();
}
}
/**
* i am dog
*/
@Test
void dog(){
dog.beanTest();
}
/**
* i am cat cat
*/
@Test
void cat(){
cat.beanTest();
}
}
