Spring MVC 异常响应编码设置

直接代码说话

@ExceptionHandler(HumanReadableException.class)
public ResponseEntity<String> handleHumanReadableException(Exception e) {
    logger.error("请求处理出错", e);
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(new MediaType("text", "plain", Charset.forName("UTF-8")));
    return new ResponseEntity<>(e.getMessage(), headers, HttpStatus.INTERNAL_SERVER_ERROR);
}
