本文介绍了一个使用Apache HttpClient库实现的发送消息线程类，包括构造方法、运行方法及HTTP POST请求的具体实现。

package com.npnets.thread;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.RequestEntity;
import org.apache.commons.httpclient.methods.StringRequestEntity;
import org.apache.log4j.Logger;

            //HttpClient client2 = new HttpClient(new HttpClientParams(),new SimpleHttpConnectionManager(true) ); 

            //方法三 服务器端设置
            //method.setRequestHeader("Connection", "close");
