안녕하세요 웹소켓 configuration 에러 질문..

Question

package com.dj.websocket.handler;import org.springframework.context.annotation.Configuration;import org.springframework.messaging.simp.config.MessageBrokerRegistry;import org.springframework.web.socket.config.annotation.AbstractWebSocketMessageBrokerConfigurer;import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;import org.springframework.web.socket.config.annotation.StompEndpointRegistry; @Configuration@EnableWebSocketMessageBrokerpublic class WebSocketMessageBrokerConfig extends AbstractWebSocketMessageBrokerConfigurer { @Override public void registerStompEndpoints(StompEndpointRegistry registry) { registry.addEndpoint("/stomp").setAllowedOrigins("http://localhost:8080").withSockJS().setStreamBytesLimit(512 * 1024).setHttpMessageCacheSize(1000).setDisconnectDelay(30 * 1000); } @Override public void configureMessageBroker(MessageBrokerRegistry registry) { registry.setApplicationDestinationPrefixes("/app"); registry.enableSimpleBroker("/subscribe", "/topic"); } }이 소스 코드 configuration 어노테이션에서 에러가 납니다.다른 컴퓨터에선 잘되는데 데스크탑에선 안됩니다.. 이유가 뭘까요? 아무리 구글링해도 안나와요.. 에러 전문입니다.

자체 해결했습니다. 아파치톰캣 문제였네요. 아파치톰캣 싹 삭제하고 인스톨러로 설치안하고 압축파일로 받아서 하니까 껏다 켯다해도 잘 작동합니다... 아파치톰캣... 너 이녀석...

roamer · Answer

여러가지 해보면서 뭔가 이상한점을 찾았습니다. 첫 임포트를 하고 서버세팅을 하고 돌리면 돌아가고 서버를 끈다음에 다시 키면 저 에러가 다시나타납니다... 이게뭔지..

roamer · Answer

다시 여러가지해보니 아파치 톰캣을 삭제하고 다시 아파치톰캣 세팅하면 됩니다.. 이게뭘까요..
