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
<!-- 使用Apache HttpClient替换Feign原生httpclient --><dependency> <groupId>com.netflix.feign</groupId> <artifactId>feign-httpclient</artifactId> <version>8.18.0</version></dependency><dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.3</version></dependency>
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@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。
这一次是一个告别，或者一个永远的告别，
