使用@Autowired注入map

个人资源分享网站：http://xiaocaoshare.com/

1.创建父接口

public interface ActivityBase {
}

2.分别创建三个实现类

@Service
public class ExperienceAct implements ActivityBase{
}

@Service
public class GroupAct implements ActivityBase{
}

@Service
public class InviteCardAct implements ActivityBase{
}

@RestController
@RequestMapping(“”)
public class ActiveController {

@Autowired
private Map<String, ActivityBase> activityBaseMap;

@GetMapping("")
public void test(){
    System.out.println(activityBaseMap.getClass().getName());
    for(Map.Entry<String,ActivityBase> map:activityBaseMap.entrySet()){
        System.out.println(map.getKey()+"=========>"+map.getValue().getClass().getName());
    }
}

}

4.启动程序并使用postMan调用这个接口，看控制台输出

java.util.LinkedHashMap
experienceAct=========>com.xiao.ActivityDesign.ExperienceAct
groupAct=========>com.xiao.ActivityDesign.GroupAct
inviteCardAct=========>com.xiao.ActivityDesign.InviteCardAct
