实体类
@Data
public class UserLoginDTO implements Serializable {
private int id;
private String username;
private String password;
}controller层测试调用接口
@RestController
@RequestMapping("user")
public class UserLoginFeignController {
@Autowired
private UserLoginFeign userLoginFeign;
@PostMapping("/loginCheckOut")
public ResponseServer loginCheckOut(@RequestBody UserLoginDTO userLoginDTO){
return userLoginFeign.loginCheckOut(userLoginDTO);
}
}fegin接口
@FeignClient(value = "medical-manage-service")
public interface UserLoginFeign {
/**
* 登录验证
* @param userLoginDTO 用户数据
* @return
*/
@PostMapping("login/loginCheckOut")
ResponseServer loginCheckOut(@RequestBody UserLoginDTO userLoginDTO);
}postman输入http://localhost:9100/user/loginCheckOut进行测试，此处用户名故意输错得出结果。
