    从类复制的说明: HandlerInterceptorAdapter
    This implementation always returns true.
    指定者:
    preHandle 在接口中 HandlerInterceptor
    覆盖:
    preHandle 在类中 HandlerInterceptorAdapter
    参数:
    request - current HTTP request
    response - current HTTP response
    handler - chosen handler to execute, for type and/or instance evaluation
    返回:
    true if the execution chain should proceed with the next interceptor or the handler itself. Else, DispatcherServlet assumes that this interceptor has already dealt with the response itself.
    抛出:
    ServletException
    IOException
  - handleNotAuthorized
```
protected void handleNotAuthorized(HttpServletRequest request,
                                   HttpServletResponse response,
                                   Object handler)
                            throws ServletException,
                                   IOException
```
    Handle a request that is not authorized according to this interceptor. Default implementation sends HTTP status code 403 ("forbidden").
    This method can be overridden to write a custom message, forward or redirect to some error page or login page, or throw a ServletException.
    参数:
    request - current HTTP request
    response - current HTTP response
    handler - chosen handler to execute, for type and/or instance evaluation
    抛出:
    ServletException - if there is an internal error
    IOException - in case of an I/O error when writing the response
