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; } }
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.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; } }
到此,相信大家对“SpringCloud Feign传对象参数调用失败怎么解决”有了更深的了解,不妨来实际操作一番吧!这里是亿速云网站,更多相关内容可以进入相关频道进行查询,关注我们,继续学习!
