直接已知子类：

RemoteDaemonHttpServlet

public abstract class DaemonHttpServlet
extends javax.servlet.http.HttpServlet

A superclass for HTTP servlets that wish to accept raw socket connections. DaemonHttpServlet starts listening for client requests in its init() method and stops listening in its destroy() method. In between, for every connection it receives, it calls the abstract handleClient(Socket client) method. This method should be implemented by the servlet subclassing DaemonHttpServlet. The port on which the servlet is to listen is determined by the getSocketPort() method.

方法详细信息

init

public void init(javax.servlet.ServletConfig config)
          throws javax.servlet.ServletException

Begins a thread listening for socket connections. Subclasses that override this method must be sure to first call super.init(config).

指定者：

接口 javax.servlet.Servlet 中的 init

覆盖：

类 javax.servlet.GenericServlet 中的 init

参数：

config - the servlet config

抛出：

javax.servlet.ServletException - if a servlet exception occurs

getSocketPort

protected int getSocketPort()

Returns the socket port on which the servlet will listen. A servlet can change the port in three ways: by using the socketPort init parameter, by setting the DEFAULT_PORT variable before calling super.init(), or by overriding this method's implementation.

返回：

the port number on which to listen

handleClient

public abstract void handleClient(Socket client)

Handles a new socket connection. Subclasses must define this method.

参数：

client - the client socket

destroy

public void destroy()

Halts the thread listening for socket connections. Subclasses that override this method must be sure to first call super.destroy().

指定者：

接口 javax.servlet.Servlet 中的 destroy

覆盖：

类 javax.servlet.GenericServlet 中的 destroy
