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.netflix.feignfeign-httpclient8.18.0org.apache.httpcomponentshttpclient4.5.3

feignClient：

@FeignClient(name = "hd-ucenter-server", fallback = SysTestServerFallbackImpl.class)public interface SysTestServer { @RequestMapping(value = "https://www.it610.com/test/test", method = RequestMethod.POST, consumes = "application/json")Object test(CurrentUser currentUser); }

RestController：

@RestController@PostMapping("/test")public class TestController { @RequestMapping(value = "https://www.it610.com/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：

【解决SpringCloud|解决SpringCloud Feign传对象参数调用失败的问题】{
"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@RestControllerAdvicepublic class GlobalExceptionHandlerResolver { //内部服务异常处理@ExceptionHandler(InternalApiException.class)public ResultResp handleGlobalException(HttpServletResponse response, InternalApiException internalApiException) {ResultResp resultResp = internalApiException.getResultResp(); 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; }}

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
