异常：Softwarecaudconnectionabort：socketwriteerror 最近在实验《Tomcat与Java Web开发技术详解》书中例⼦程序时，发现⼀个异常：Software caud connection abort: socket write error ⽤Java 套接字创建HTTP 客户与服务器程序
服务器程序

}catch(Exception e){
System.out.println("port = 8080 (默认)");

rverSocket = new ServerSocket(port);
System.out.println("服务器正在监听端⼝： "+LocalPort());
while(true){

//等待客户的TCP连接请求
final Socket socket = rverSocket.accept();
System.out.println("建⽴⼀个客户端的新的TCP连接，该客户的地址为："+InetAddress()+":"+Port());

执⾏过程：1.在eclip中对服务端程序debug启动
2.在eclip中对客户端程序debug启动，配置启动参数“hello1.htm”漫画人物大全
3.在服务端红⾊部分，函数rvice中设置断点，单步调试，出现异常Software caud connection abort: socket write error
分析：单步调试耗时⽐较长，服务端接收的socket已经被关闭。
