第一次连接client.newWebsocket("ws://whttp://www.xx.com%22/) 没有任何问题。但是关闭close后再去连接就报错

client.close之后，把client赋值为null，再次newWbeSocket的时候，再去初始化client。
根据你的描述，你使用 OkHttp 4.2.9 时尝试连接 WebSocket，第一次连接没有问题，但是在关闭连接后再次连接时出现错误。错误是“java.io.InterruptedIOException: executor rejected”，这可能是因为你在调用 client.newWebSocket() 时没有正确关闭上一个 WebSocket 连接。你应该在关闭 WebSocket 连接后调用 client.dispatcher().executorService().shutdown() 来关闭 executorService。这样可以避免连接池中的线程被无限制地积累。

该错误java.io.InterruptedIOException: executor rejected通常意味着，程序试图在已经关闭的OkHttpClient对象上执行操作。您可以在每次调用完close()方法后重新创建新的OkHttpClient实例，或者使用一个单例或全局变量来保存客户端实例，以便可以在需要时重复使用它。
在Java OkHttp4.2.9中，连接同一WebSocket两次会抛出“executor rejected”的异常。 问题可能是在执行异步调用时拒绝了执行程序，这可能是因为您同时发起了多个请求并达到了连接限制。解决方法是增加连接限制，例如使用线程池并增加最大线程数，或者通过管理WebSocket实例来确保同一时间只有一个WebSocket连接打开。

可能是因为在关闭WebSocket连接后，相关资源没有得到及时释放，导致无法重新连接。可以尝试在连接之前检查WebSocket对象是否已经被释放，如果没有释放，则先调用WebSocket.close()方法进行释放，再重新连接。
以下是一个简单的示例代码，演示了如何通过检查WebSocket对象的readyState属性来检测WebSocket是否已经被释放，并在必要时进行释放和重新连接：
var ws = null;
function connect() {
if (ws != null && ws.readyState != WebSocket.CLOSED) {
// 如果WebSocket对象未被释放，则先关闭WebSocket对象
ws.close();
}
// 创建新的WebSocket对象并连接
ws = new WebSocket("ws://www.xx.com/");
// 在onopen、onmessage、onclose等事件处理函数中处理WebSocket的连接、数据接收和断开连接等操作
ws.onopen = function() {
console.log("WebSocket connected");
};
ws.onmessage = function(event) {
console.log("Received data: " + event.data);
};
ws.onclose = function() {
console.log("WebSocket disconnected");
};
}
在以上示例代码中，connect()函数会首先检查WebSocket对象是否已经被释放，如果没有被释放，则先调用WebSocket.close()方法进行释放。接着，创建新的WebSocket对象并连接，并在相关事件处理函数中进行操作。
需要注意的是，WebSocket的行为和性能在不同浏览器和环境中可能会有所不同。如果以上方法不能解决您的问题，可以尝试参考浏览器的相关文档或使用第三方的WebSocket库。
我解决了。去掉了
client.dispatcher().executorService().shutdown()
