Solve the problem of SpringCloud Feign transfer object parameter call failure

SpringCloud Feign Transfer Object Parameter Call Failed

GET request mode is not supported Replace Feign native httpclient with Apache HttpClient @ RequestBody receives json parameters

bootstrap-local.yml

feign:
  httpclient:
    enabled: true

pom.xml

<!--  Use Apache HttpClient Replace Feign Native httpclient -->
<dependency>
    <groupId>com.netflix.feign</groupId>
    <artifactId>feign-httpclient</artifactId>

</dependency>
<dependency>
    <groupId>org.apache.httpcomponents</groupId>

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(" Call test\n");
       return currentUser;
    }
}

The problem that Feign exception cannot be passed in SpringCloud

Because the exception thrown inside cloud is not handled, Feign gets the default wrapper exception result of spring as follows:

{
"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"
}

Return status under custom exception handling

@Slf4j
@RestControllerAdvice
public class GlobalExceptionHandlerResolver {
 
    // Internal service exception handling 
    @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());// Return 500 Anomaly 
        response.setContentType(MediaType.APPLICATION_JSON_UTF8.toString());
        return resultResp;
    }
}
