[Spring Boot] Spring Resttemplate 예외 처리

 

LOCAL_SAVE_URL 에서 오류가 발생하면 4xx번, 5xx번대 오류가 넘어옵니다.

try {
  ResponseEntity<String> response = restTemplate.postForEntity( LOCAL_SAVE_URL, entity, String.class );

  logger.debug( "response :: {}", response );
  logger.debug( "result :: {}", response.getStatusCodeValue() );
  logger.debug( "result :: {}", response.getBody() );
  //logger.debug( "result :: {}", (List) response.getBody().get( "list" ) );
} catch ( HttpStatusCodeException e ) {
  String errorpayload = e.getResponseBodyAsString();
  logger.debug( "error :: {}", errorpayload );
}

org.springframework.web.client.HttpServerErrorException: 500 Internal Server Error at org.springframework.web.client.DefaultResponseErrorHandler.handleError(DefaultResponseErrorHandler.java:94) ~[spring-web-4.2.3.RELEASE.jar:4.2.3.RELEASE]

해결책으로 Try~catch 합니다.

 try {
	return restTemplate.exchange(url, httpMethod, httpEntity, String.class);
} catch(HttpStatusCodeException e) {
    return ResponseEntity.status(e.getRawStatusCode()).headers(e.getResponseHeaders())
                .body(e.getResponseBodyAsString());
}
