使用feign客户端传参接收不到的问题及解决

@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {
 
    @PostMapping("/save")
    public String save(User user){
        log.info("provider: 处理save请求，参数为：{}",user);
        return "success";
    }

@FeignClient(name = "service-provider",fallback = UserHystrix.class)
public interface UserController {
 
    @PostMapping("/user/save")
    String save(User user); 
}

@RestController
@Slf4j
public class FeignController {
 
    @Autowired
    private UserController userController;
 
    @RequestMapping("/feign")
    public String test(){
        User user = new User();
        user.setName("zhangsan");
        user.setAge(10);
        log.info("feign调用开始。。。。");
        String result = userController.save(user);
        log.info("feign: 返回： {}", result);
        return "success";
    }   
}

@RestController
@RequestMapping("/user")
@Slf4j
public class UserController {
 
    @PostMapping("/save")
    // 注意加上requestBody,否则容易接收不到参数
    public String save(@RequestBody User user){
        log.info("provider: 处理save请求，参数为：{}",user);
        return "success";
    } 
}

@PostMapping("/bizTask/selectNonCompleteByShopIds")
List<BizTask> selectNonCompleteByShopIds(@RequestBody List<Long> shopIds);
