TelnetAppender类

TelnetAppender类将日志消息发送到指定的Socket端口（默认为23），用户可以使用telnet连接以获取日志信息。这里的实现貌似没有考虑到telnet客户端如何退出的问题。另外，在windows中可能默认没有telnet支持，此时只需要到”控制面板”->”程序和功能”->”打开或关闭windows功能”中大概Telnet服务即可。TelnetAppender使用内部类SocketHandler封装发送日志消息到客户端，如果没有Telnet客户端连接，则日志消息将会直接被抛弃。

1 private SocketHandler sh;

2 private int port = 23;

4 public void activateOptions() {

5try {

6sh = new SocketHandler(port);

7sh.start();

8} catch (InterruptedIOException e) {
