尝试通过我的Apache2服务器访问ws:// localhost:8080 /时收到错误500.该服务器运行OpenSuse Leap 42.1和Apache 2.4.16.

启用了这些Apache2模块:mod_proxy,mod_proxy_http,mod_proxy_wstunnel.

从本地网络调用请求时,一切正常.网址示例:http://<myhost-ip-address>/api/ws/<some-url>.它返回状态101和响应:Upgrade: websocket.没关系.

来自外部网络的同类请求失败.网址示例:ws://www.mysite.com/api/ws/<some-url>.它返回错误500.

Apache访问日志包含: GET /api/ws/<some-url> HTTP/1.1" 500 ...

Apache错误日志包含: [proxy:warn] AH01144: No protocol handler was valid for the URL /api/ws/<some-url>. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.

我的httpd.conf:

<VirtualHost *:80>
ServerName mysite.com
ServerAlias mysite.com
# Redirection for ws protocol
ProxyPreserveHost On
ProxyVia full
ProxyRequests OffHere
RewriteEngine On
RewriteCond %{REQUEST_URI}  ^/api/ws/(.*)           [NC]

线程没有睡觉我有问题.
我不能把我的整个代码放在这里.所以,为了重现,这里是一个等待5秒的基本代码.

try {
    int millisec = 5000;
    System.out.println(new Date());
    System.out.println("We wait " + millisec + " milliseconds");
    Thread.sleep(millisec);
    System.out.println(new Date());
} catch (Exception e) {
    e.printStackTrace();
}

输出:

我们等待5000毫秒

一切都好.
但是当我把这段代码放在一个线程中时,没有睡觉.此代码示例:

try {
    Thread aThread = new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                int millisec = 5000;
                System.out.println(new Date());
                System.out.println("We wait " + millisec + " milliseconds");
                Thread.sleep(millisec);
                System.out.println(new Date());
            } catch (Exception e) {
                e.printStackTrace(); …
