检查端口是否绑定&；用Java进行听力训练'；重置'；袜子槽？

尝试连接到它最多60秒（如果由于服务器尚未绑定套接字而连接失败，请重试）

或

检查服务器当前是否正在接受连接

当我现在运行第一个示例时，我得到如下输出

new CheckServerStarted(addr).check(1, false);

很明显，它不是在两次尝试之间等待1秒

---

我猜我需要在两次尝试之间“重置”频道？是否每次都需要创建一个新的套接字？

即使连接尝试失败，也无法重新连接已连接的套接字。必须关闭它并创建一个新的

其他问题：

• 你的插座漏水了
• 摆脱睡眠，使用

  选择器

• 打印

  e

  而不是

  e.getMessage（）

  。如果您一开始就正确地完成了这项工作，而不是整天盯着“null”，那么您可能已经自己解决了这个问题
• 调用

  finishConnect（）

  的

  IOException

  是致命的，不是重试的信号

“调用finishConnect（）的IOException是致命的，不是重试的信号。”-我在讨论服务器没有启动的可能性。我承认这个问题有点懒惰，但我的主要问题是SocketChannel w.r.t.重用的语义，而且无法通过快速的谷歌搜索找到它。

IOException

对套接字来说是致命的。您必须关闭套接字并创建一个新的套接字。@b如果OP_CONNECT已启动，您将调用

finishConnect（）

，如果服务器尚未启动，则无法调用。

new CheckServerStarted(addr).check(60, true);

new CheckServerStarted(addr).check(1, false);
