I have used spring implementation of sockjs websocket server and unable to transmit message over 8KB, following is the error
2014-02-12 19:36:29,990 - org.springframework.web.socket.sockjs.transport.session.WebSocketServerSockJsSession - DEBUG - SockJS session id=35n41xel was closed, CloseStatus [code=1009, reason=The decoded text message was too big for the output buffer and the endpoint does not support partial messages]
Any Idea how can I increase the buffer size
I used following factory as spring sockjs leverages tomcat container (App is deployed in tomcat and I also debugged to confirm that it indeed uses tomcat lib)
@Bean
public WebSocketContainerFactoryBean createWebSocketContainer() {
WebSocketContainerFactoryBean container = new WebSocketContainerFactoryBean();
container.setMaxTextMessageBufferSize(16384);
container.setMaxBinaryMessageBufferSize(8192);
return container;
}
And then my URL mapping looks
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(coBrowseSockJsCustomerHandler(), "/sockjs/cobrowse/customer/").withSockJS();}
Do I need to set this bean with sockjs somewhere? how does sockjs knows that it has to use this facory?
Solved it by using clue from http://docs.spring.io/spring/docs/4.0.1.RELEASE/javadoc-api/index.html?org/springframework/web/socket/sockjs/SockJsService.html -got hold of ServletServerContainerFactoryBean and set the properties, this worked
@Bean
public ServletServerContainerFactoryBean createServletServerContainerFactoryBean() {
ServletServerContainerFactoryBean container = new ServletServerContainerFactoryBean();
container.setMaxTextMessageBufferSize(32768);
container.setMaxBinaryMessageBufferSize(32768);
logger.info("Websocket factory returned");
return container;
}
