无法连接到我的tomcat 8 websocket
我编写了一个连接到服务器上的websocket的客户端程序。 我使用示例工作设置tomcat8并使用我的客户端程序命中EchoAnnotation端点。
我写了这个端点程序如下：
@ServerEndpoint(value = "/websocket") public class PortServer implements AirMessageListener { public PortServer() { } @OnOpen public void start(Session session) { //do stuff } @OnClose public void end() { //do stuff } } @OnMessage public void incoming(String message) { //do stuff } @OnError public void onError(Throwable tw) throws Throwable { //do stuff } 我编译它并创建一个名为portserver的war文件，并将其放入我的tomcat webapps目录。 然后我将我的客户端程序从连接到： ws://localhost:8080/examples/websocket/echoAnnotation到ws://localhost:8080/portserver/websocket并运行它。 我明白了：

我在我的portserver应用程序中放置了一个index.html，可以点击： http://localhost:8080/portserver就好了，这意味着目录没问题。 然后我validation我的class级在我的WEB-INF / classes目录中。
我查看了这些示例并找到了我认为可能是启用端点的“魔术”类的ExamplesConfig类，因此我实现了自己的并且卡在了jar文件中。
/** * */ package com.corrisoft.air.portserver; import java.util.HashSet; import java.util.Set; import javax.websocket.Endpoint; import javax.websocket.server.ServerApplicationConfig; import javax.websocket.server.ServerEndpointConfig; /** * @author Corrisoft Android Development */ public class WebSocketConfig implements ServerApplicationConfig { /* (non-Javadoc) * @see javax.websocket.server.ServerApplicationConfig#getAnnotatedEndpointClasses(java.util.Set) */ @Override public Set<Class> getAnnotatedEndpointClasses(Set<Class> scanned) { // Deploy all WebSocket endpoints defined by annotations in the // web application. Filter out all others to avoid issues when running // tests on Gump Set<Class> results = new HashSet(); for (Class clazz : scanned) { if (clazz.getPackage().getName().startsWith("com.corrisoft.air")) { System.out.println("Adding endpoint for:" + clazz.getName()); results.add(clazz); } } return results; } /* (non-Javadoc) * @see javax.websocket.server.ServerApplicationConfig#getEndpointConfigs(java.util.Set) */ @Override public Set getEndpointConfigs( Set<Class> scanned) { return null; } }
它似乎没有运行这个类。
我错过了一些配置吗？
事实certificate，问题是我的一个依赖类在类路径中丢失了。 在这些情况下，Tomcat 8不会添加端点，也不会在日志中引发exception。
我将相同的war文件部署到tomcat 7并获得exception。 处理类路径直到它好，然后部署回到tomcat 8，它现在正在工作。
我在这里创建了缺陷56442： https ：//issues.apache.org/bugzilla/show_bug.cgi？id = 56442，用于tomcat吃exception而不是在日志中显示。
对于其他受此困扰的人; 仔细看看你的URI。 我根据配置文件将我的url拼凑在一起。 构建URL时我错过了一个“/”字符，并确信它是正确的！ 如果您执行以下操作，我建议打印出“构建的URL”并在追逐尾部之前仔细研究：
public static final String WEBSOCKETHOST = "localhost"; // TODO: Get from configuration public static final int WEBSOCKETPORT = 10080; // TODO: Get from configuration public static final String WEBSOCKETSERVERROOT = "/sceagents"; // TODO: Get from configuration public static final String WEBSOCKETSERVERENDPOINT = "neo"; // TODO: Get from configuration public static final String WEBSOCKETPROTOCOL = "ws"; // TODO: Get from configuration String uri = WEBSOCKETPROTOCOL + "://" + WEBSOCKETHOST + ":" + Integer.toString(WEBSOCKETPORT) + WEBSOCKETSERVERROOT + "/" + WEBSOCKETSERVERENDPOINT;
