Spring cloud openfeign status 404

问题描述 投票：0回答：1

我正在研究一个杂项服务示例，我有4种微服务：-尤里卡服务器（发现）-网关服务（zuul代理）-资源服务（假客户）-用户服务（用户分类示例）

一切正常；即使当我通过代理调用用户服务api时，它也可以完美地工作；但是我的目标是使用假客户端调用用户服务api，这时我得到了错误

feign.FeignException $ NotFound：状态404读取UserDetailsS​​erviceFeign＃getUserById（Long）

这是我的主班：

@EnableFeignClients
@EnableEurekaClient
@SpringBootApplication
public class ResourceServiceApplication {
public static void main(String[] args) {
    SpringApplication.run(ResourceServiceApplication.class, args);
  }
}

这是我的FeignClient界面：

@FeignClient(name = "user-service")
public interface UserDetailsServiceFeign {

@PostMapping(value = "/saveUpdate")
UserDetailsDTO saveUpdate(@RequestBody UserDetailsDTO inputUser);

@GetMapping(value = "/getById/{id}")
UserDetailsDTO getUserById(@PathVariable(name = "id") Long id);

@GetMapping(value = "/getByName/{name}")
List<UserDetailsDTO> getUserByName(@PathVariable(name = "name") String name);

}

这是我的控制器api类

@RestController
@RequestMapping("/api")
public class UserDetailsResourceController {

@Autowired
private UserDetailsServiceFeign userDetailsServiceFeign;

@PostMapping(value = "/saveUpdate")
public UserDetailsDTO saveUpdate(@RequestBody UserDetailsDTO inputUser) {
    return userDetailsServiceFeign.saveUpdate(inputUser);
}

@GetMapping(value = "/getById/{id}")
public UserDetailsDTO getUserById(@PathVariable(name = "id") Long id) {
    return userDetailsServiceFeign.getUserById(id);
}

@GetMapping(value = "/getByName/{name}")
public List<UserDetailsDTO> getUserByName(@PathVariable(name = "name") String name) {
    return userDetailsServiceFeign.getUserByName(name);
}

}

这是我的conf属性：

spring:
  application:
    name: resource-service
eureka:
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://localhost:8661/eureka
  instance:
    hostname: localhost
server:
  port: 8182

可悲的是，我忘记提及Feign接口中的映射前缀；这会导致路径误导。
