创建自定义异常类：

public class TokenCheckException extends RuntimeException{

    private String msg;

    private String code;

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public TokenCheckException(String msg, String code) {
        this.msg = msg;
        this.code = code;
    }
}

异常处理类：

@RestControllerAdvice
public class GlobalExceptionHandler {

    private static final Logger log = LoggerFactory.getLogger(GlobalExceptionHandler.class);

    @ExceptionHandler(TokenCheckException.class)
    public AjaxResult handleTokenCheckException(TokenCheckException e, HttpServletRequest request) {
        String requestURI = request.getRequestURI();
        log.error("请求地址'{}',权限校验失败'{}'", requestURI, e.getMessage());
        return AjaxResult.error(e.getCode(),e.getMsg());
    }
}

/**
 * 操作消息提醒

public class AjaxResult extends HashMap<String, Object>
{
    private static final long serialVersionUID = 1L;

    /** 状态码 */
    public static final String CODE_TAG = "code";

    /** 返回内容 */
    public static final String MSG_TAG = "msg";

    /** 数据对象 */
    public static final String DATA_TAG = "data";

    /**
     * 初始化一个新创建的 AjaxResult 对象，使其表示一个空消息。
     */
    public AjaxResult()
    {
    }

    /**
     * 初始化一个新创建的 AjaxResult 对象
     *
     * @param code 状态码
     * @param msg 返回内容
     */
    public AjaxResult(String code, String msg)
    {
        super.put(CODE_TAG, code);
        super.put(MSG_TAG, msg);
    }



    /**
     * 返回成功消息
     *
     * @return 成功消息
     */
    public static AjaxResult success(String code, String msg)
    {
        return new AjaxResult(code, msg);
    }


    public static AjaxResult error(String code, String msg)
    {
        return new AjaxResult(code, msg);
    }
    
}
