弹簧云打开外部状态404

Question

我正在处理一个错误服务示例，我有4个微服务：-尤里卡服务器(发现)-网关服务(zuul代理)-资源服务(外部客户端)-用户服务(用户crud示例)

一切都很好；即使我通过代理调用用户服务api，它也能完美地工作；但我的目标是使用foreign客户端调用用户服务api，此时我得到错误

foreign.FeignException$NotFound:状态404正在读取UserDetailsServiceFeign#getUserById(Long)

Stacktrace:

这是我的主要类：

@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

Answer 1

遗憾的是，我忘了在Feign接口中提到映射前缀；这导致路径误导。
