aplication.yml添加配置

eureka:
  client:
    serviceUrl:
      defaultZone: http://username:password@localhost:9000/eureka/
  instance:
    prefer-ip-address: true

提供登录测试方法

/**

@Controller
@Slf4j
public class UserController extends BaseController {

    @Autowired
    private IUserService userService;

    /**
     * 登录
     *

    @RequestMapping("/user/login")
    @ResponseBody
    public Result login(@RequestParam String userName, @RequestParam String password, String validCode) {
        Result result = new Result();
        try {
            result = success(userService.login(userName,password));
        } catch (Exception e) {
            log.error("/login system error {}-{}", e.getMessage(), e);
            result = error(UserErrorCode.SYSTEM_ERROR_WITH_MSG, e.getMessage());
