解决SpringCloud Feign传对象参数调用失败的问题

解决SpringCloud Feign传对象参数调用失败的问题

SpringCloud Feign传对象参数调用失败

不支持GET请求方式

使用Apache HttpClient替换Feign原生httpclient

@RequestBody接收json参数

bootstrap-local.yml

feign:

httpclient:

enabled: true

pom.xml

com-flix.feign

feign-httpclient

8.18.0

org.apache.httpcomponents

httpclient

4.5.3

feignClient：

@FeignClient(name = "hd-ucenter-server", fallback = SysTestServerFallbackImpl.class)

public interface SysTestServer {

@RequestMAPPing(value = "/test/test", method = RequestMethod.POST, consumes = "application/json")

Object test(CurrentUser currentUser);

}

RestController：

@RestController

@PostMapping("/test")

public class TestController {

@RequestMapping(value = "/test")

public Object test(@RequestBody CurrentUser currentUser) {

System.out.printf("调用test\n");

return currentUser;

}

}

SpringCloud中Feign异常无法传递的问题

因为 cloud内部抛出异常不进行处理，Feign获取spring默认包装异常结果如下：

{

"timestamp": "2017-12-27 15:01:53",

"status": 500,

"error": "Internal Server Error",

"exception": "com.keruyun.loyalty.commons.master.exception.BusinessException",

"message": "Request processing failed; nested exception is {\"code\":1000, \"message\":\"test Exception\"}",

"path": "/coupon/cloud/commercial/8469"

}

自定义的异常处理下返回状态

@Slf4j

@RestControllerAdvice

public class GlobalExceptionHandlerResolver {

//内部服务异常处理

@ExceptionHandler(InternalApiException.class)

public ResultResp> handleGlobalException(HttpServletResponse response, InternalApiException internalApiException) {

ResultResp> resultResp = internalApiException.getResuliKJIOQxaaEtResp();

log.error(internalApiException.getMessage(), internalApiException);

response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());//返回500异常

response.setContentType(MediaType.APPLICATION_JSON_UTF8.toString());

return resultResp;

}

}
