统一异常处理 构建 ResultBody 相应体

结合i18n 支持通配符匹配

使用实例 Contrller

     /**
     * 获取 用户接口
     * @param account
     * @return
     * @throws GlobalErrorInfoException
     */
    @GetMapping
    public ResultBody findUsers(String account) throws GlobalErrorInfoException {
        // 入参为空
        if (StringUtils.isEmpty(account)) {
            throw new GlobalErrorInfoException(ErrorInfoEnum.PARAMS_NOT_NULL);
        }
        return new ResultBody(new User(1L, account, "admin", 18, 1));
    }

     /**
         * 测试支持通配符匹配
         * @param account
         * @return
         * @throws GlobalErrorInfoException
         */
        @GetMapping("args")
        public ResultBody findUsers3(String account) throws GlobalErrorInfoException {
            // 入参为空
            if (StringUtils.isEmpty(account)) {
                Object[] args = new Object[]{"啊啊啊啊", "哈哈哈哈哈"};
                throw new GlobalErrorInfoException(ErrorInfoEnum.PARAMS_NOT_NULL2, args);
            }
            return new ResultBody(new User(1L, account, "admin", 18, 1));
        }

    /**
     * 测试全局异常
     * @param account
     * @return
     */
    @GetMapping("other")
    public ResultBody otherExpetion(String account) {
        int i = 1 / 0;
        return new ResultBody(new User(1L, account, "admin", 18, 1));
    }

Exception Handler

@RestControllerAdvice
public class GlobalErrorInfoHandler {


private static Logger logger = LoggerFactory.getLogger(GlobalErrorInfoHandler.class);

     /**
         * 全局系统异常
         * @param request
         * @param exception
         * @return
         */
        @ExceptionHandler(value = RuntimeException.class)
        public ResultBody errorHandlerOverJson(HttpServletRequest request, RuntimeException exception) {
            logger.error("全局异常:", exception.getMessage());
            ResultBody result = new ResultBody(GlobalErrorInfoEnum.NOT_FOUND);
            return result;
        }
        
    
         /**
             * GlobalErrorInfoException 系统异常
             * @param request
             * @param exception
             * @return
             */
    @ExceptionHandler(value = GlobalErrorInfoException.class)
    public ResultBody errorHandlerOverJson(HttpServletRequest request, GlobalErrorInfoException exception) {
        ErrorInfo errorInfo = exception.getErrorInfo();
        getMessage(errorInfo,exception.getArgs());
        ResultBody result = new ResultBody(errorInfo);
        return result;
    }


    private void getMessage(ErrorInfo errorInfo,Object...agrs) {
        String message = null;
        if (!StringUtils.isEmpty(errorInfo.getCode())) {
            message = MessageUtils.message(errorInfo.getCode(), agrs);
        }
        if (message == null) {
            message = errorInfo.getMessage();
        }
        errorInfo.setMessage(message);
    }
}
