init

public void init(ServletConfig config)
          throws ServletException

从接口 Servlet 复制的描述

Called by the servlet container to indicate to a servlet that the servlet is being placed into service.

The servlet container calls the init method exactly once after instantiating the servlet. The init method must complete successfully before the servlet can receive any requests.

The servlet container cannot place the servlet into service if the init method

1. Throws a ServletException
2. Does not return within a time period defined by the Web server

指定者：

接口 Servlet 中的 init

覆盖：

类 ProxyServlet 中的 init

参数：

config - a ServletConfig object containing the servlet's configuration and initialization parameters

抛出：

ServletException - if an exception has occurred that interferes with the servlet's normal operation

protected String filterResponseHeaderValue(String headerName,
                                           String headerValue,
                                           HttpServletRequest request)
