websocket一直在提示没有为它配置错误处理信息
2022-07-28 16:20:22.426 [http-nio-8080-exec-5] ERROR org.apache.tomcat.websocket.pojo.PojoEndpointBase:175 - No error handling configured for [org.jeecg.modules.message.websocket.WebSocket] and the following error occurred java.io.EOFException: null at org.apache.tomcat.util.net.NioEndpoint$NioSocketWrapper.fillReadBuffer(NioEndpoint.java:1231) at org.apache.tomcat.util.net.NioEndpoint$NioSocketWrapper.read(NioEndpoint.java:1141) at org.apache.tomcat.websocket.server.WsFrameServer.onDataAvailable(WsFrameServer.java:72) at org.apache.tomcat.websocket.server.WsFrameServer.doOnDataAvailable(WsFrameServer.java:171) at org.apache.tomcat.websocket.server.WsFrameServer.notifyDataAvailable(WsFrameServer.java:151) at org.apache.tomcat.websocket.server.WsHttpUpgradeHandler.upgradeDispatch(WsHttpUpgradeHandler.java:148) at org.apache.coyote.http11.upgrade.UpgradeProcessorInternal.dispatch(UpgradeProcessorInternal.java:54) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:59) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:868) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1590) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:748)
原因分析：
提示：我这里是websocket在断开连接时就会提示这个错误，但websocket连接的时候没问题，不太清楚怎么回事，如有大佬清楚，希望可以指教一下，谢谢
解决方案：
既然提示没有为它配置错误处理，那我们就为它配置一下错误处理
@OnError
public void onError(Session session, Throwable t) {
//什么都不想打印都去掉就好了
log.info("【websocket消息】出现未知错误 ");
//打印错误信息，如果你不想打印错误信息，去掉就好了
//这里打印的也是 java.io.EOFException: null
t.printStackTrace();
}
注意上面两个参数是一点要的，不要的话启动会报错，不要问我为什么，我之前因为没给参数在百度待了两个小时才出来（主要因为自己太菜了（手动狗头））
