java swing上做socket 通信抛异常java.net.SocketException: Connection reset 自己搞了一天了都不行

8988CVB 2017-06-20 04:47:32
客户端我是有两个窗口的 运行第一个窗口输入服务端IP地址 和 第二个窗口的标题 输入完点击确定就抛出java.net.SocketException: Connection reset了 控制台显示是客户端代码出异常 是读取服务端发来信息出异常的 下面有客户端代码

如果客户不用两个窗口 在代码里面设置服务端ip地址 运行就可以通信 不抛出这个异常
客户端不用两个窗口就可以通信了

通过第一个窗口输入ip地址来打开到第二个窗口就不行了 抛出这个异常了 服务端也显示连接上了 就是客户端出这个异常了



我想不通了 通过第一个窗口输入ip地址来打开到第二个窗口就不行了 跟直接在main里面 new 第二个窗口不一样吗 为什么 通过第一个窗口输入ip地址来打开到第二个窗口就不行了 抛出这个异常了
我知道这个异常时有一端关闭了 还发送信息造成的 但这刚刚执行 没有哪一端是关闭的啊 真想不通
控制台显示异常显示在客户端代码 读取服务端来信息的代码 下面是客户端代码
