- java.lang.String getServletInfo()
- ServletConfig getServletConfig()

**生命周期：** **Web容器加载Servlet并将其实例化后，Servlet生命周期开始**，容器运行其**init()方法**进行Servlet的初始化；请求到达时调用Servlet的**service()方法**，service()方法会根据需要调用与请求对应的**doGet或doPost**等方法；当服务器关闭或项目被卸载时服务器会将Servlet实例销毁，此时会调用Servlet的**destroy()方法**。**init方法和destory方法只会执行一次，service方法客户端每次请求Servlet都会执行**。Servlet中有时会用到一些需要初始化与销毁的资源，因此可以把初始化资源的代码放入init方法中，销毁资源的代码放入destroy方法中，这样就不需要每次处理客户端的请求都要初始化与销毁资源。
