关于#springboot#集成security+jwt的问题，如何解决？

Question

springboot项目集成spring security+jwt

每次运行时抛出自定义异常时都会报空指针

/**
* 自定义异常
*/
@Data
@AllArgsConstructor
@NoArgsConstructor
public class CommonException extends RuntimeException {
    private int code;
    private String msg;

    public CommonException(ResultCode resultCode) {
        this.code = resultCode.getCode();
        this.msg = resultCode.getMessage();
    }
}

/**
* 自定义捕获
*/
@RestControllerAdvice
public class CommonExceptionHandler {

    public static final Logger logger = LoggerFactory.getLogger(CommonExceptionHandler.class);

    /**
     * 全局异常捕捉处理
     * @param ex
     * @return
     */
    @ExceptionHandler(value = Exception.class)
    public R errorHandler(HttpServletRequest req, Exception ex) {
        logger.error(String.format("发生未处理的异常={%s},url={%s},params={%s}",
                ex.getMessage(),req.getRequestURL(),req.getParameterMap().toString()),ex);
        return R.fail(100,ex.getMessage());
    }

    /**
     * 拦截捕捉自定义异常 CommonException.class
     * @param ex
     * @return
     */
    @ExceptionHandler(value = CommonException.class)
    public Map myErrorHandler(HttpServletRequest req, CommonException ex) {
        Map map = new HashMap();
        map.put("code", ex.getCode());
        map.put("msg", ex.getMsg());
        return map;
    }
}

/**
* 使用
*/
throw new CommonException(401, "token失效，请重新登录");

过滤器点进去定位到63行，这里报空指针，看是否使用对象属性，对象应该为null
