查看tomcat服务器返回的响应消息,Tomcat上的WebSocket握
⼿返回意外响应代码500
我有⼀个WebSocket应⽤程序，该程序以编程⽅式注册了端点，⽽没有使⽤注释。
相关代码为：ServerEndpointConfig.Configurator configurator =
(ServerEndpointConfig.wInstance();
ServerEndpointConfig serverEndpointConfig = ServerEndpointConfig.Builder
.create(endpointClass, endpointPath)
.configurator(configurator)
.build();
ServerContainer serverContainer = (ServerContainer)app
.getServletContext()
.
getAttribute("javax.websocket.server.ServerContainer");
serverContainer.addEndpoint(serverEndpointConfig);
当我在带有嵌⼊式Jetty容器的IDE中运⾏它时，⼀切⼯作正常，其中依赖关系通过Maven在tomcat-websocket和tomcat-websocket-api 库上，但是当我在Tomcat(8.5.5)中部署它，然后尝试建⽴WebSocket连接，在浏览器的控制台中出现以下错误：WebSocket与“
ws：//127.0.0.1：8080 / echo”的连接失败：WebSocket握⼿期间出错：意外的响应代码：500
我在Catalina输出中未记录任何错误或其他信息，并且不确定如何调试此问题。
我需要以编程⽅式配置端点，因为在编译时尚不了解许多信息，因此请不要将我指向注释解决⽅案。
