一、框架代码的实现使用Socket是最完美的的远程连接超时设置技术，下面是创建Socket对象的代码： 建立连接一般的写法是：Socket s = new Socket(host, port); 而要定制超时的写法则为：SocketAddress addr = new InetSocketAddress(host, port);Socket s = new Socket();s.connect(addr, timeoutInMilliSeconds);这种写法使用了底层的socket技术。如果使用JMX远程管理API, 通常不能访问socket。如果一定要使用这种技术的话，需颇费一番周折。其工 阅读全文
