一个接口有多个实现类,Controller方法中动态调用具体都实现类

接口

public interface IDemoService {

    public String test();
}

实现类1

@Service("demoServiceImpl1")
public class DemoServiceImpl1 implements IDemoService {
    @Override
    public String test() {
        System.out.println("实现类1");
        return "实现类1";
    }
}

实现类2

@Service("demoServiceImpl2")
public class DemoServiceImpl2 implements IDemoService {
    @Override
    public String test() {
        System.out.println("实现类2");
        return "实现类2";
    }
}

Controller

@RequestMapping("demo")
@RestController
public class DemoController extends BaseController {
    @Autowired
    private Map service;


    @RequestMapping(value="/test", method = RequestMethod.POST)
    @ResponseBody
    public Result test(@RequestBody String json) {

        //动态获取serviceImplName逻辑
        String serviceImplName = "demoServiceImpl2";
		//获取到具体的实现类
        IDemoService iDemo = service.get(serviceImplName);
        String result = iDemo.test();
		System.out.println("实现类输出结果:" + result);
        return null;
    }
}

System.out.println输出结果

实现类输出结果:实现类2
