spring註入map,spring註入多個實現類在map里

一個介面，兩個實現類

介面：

public interface TestService {
    void test();
}

兩個實現類

@Component("testOService")
public class TestOService implements TestService {
    @Override
    public void test() {
        System.out.println("testOService");
    }
}

@Component("testTwoService")
public class TestTwoService implements TestService {
    @Override
    public void test() {
        System.out.println("testTwoService");
    }
}

查看：

@Service
public class UserInfoService {
    
    @Autowired
    private Map<String ,TestService> testServiceMap;
    @PostConstruct
    public void init(){
        testServiceMap.get("testOService").test();
        testServiceMap.get("testTwoService").test();
    }
}
