Question

jsp中tomcat8的websocket

public class ExamplesConfig implements ServerApplicationConfig {

@Override
public Set<ServerEndpointConfig> getEndpointConfigs(
Set<Class<? extends Endpoint>> scanned) {

Set<ServerEndpointConfig> result = new HashSet<>();

if (scanned.contains(EchoEndpoint.class)) {
result.add(ServerEndpointConfig.Builder.create(
EchoEndpoint.class,
"/websocket/echoProgrammatic").build());
}

return result;
}

@Override
public Set<Class<?>> getAnnotatedEndpointClasses(Set<Class<?>> scanned) {
// Deploy all WebSocket endpoints defined by annotations in the examples
// 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("websocket.")) {
results.add(clazz);
}
}
return results;
}
}
启动tomcat要怎么加载ExamplesConfig这个类？

Answer 1

我最近也在搞WebSocket，不过是用的c++，websocket客户端都一样，你要是要个websocket服务器你可以用java写一个嘛，干嘛用tomcat呢？

追问

已经解决了，java的websocket api要javaEE7才有，所以先用tomcat的，再说了，tomcat这个容器比较好用吧
