The characteristics, such as the buffer size of the messages, timeout, and so on, can be configured for the Tomcat runtime environment by adding the bean for WebSocketConfigurer, as follows:

@Bean 
public ServletServerContainerFactoryBean  
  createWebSocketContainer()  
{ 
  ServletServerContainerFactoryBean webSocketcontainer =  
    new ServletServerContainerFactoryBean(); 
    webSocketcontainer .setMaxTextMessageBufferSize(9000); 
    webSocketcontainer .setMaxBinaryMessageBufferSize(9000); 
    return webSocketcontainer ; 
  } 
} 

The equivalent XML configuration can be written like this:

<bean class= "org.springframework.web.socket.server.standard. 
  ServletServerContainerFactoryBean"> 
  <property name="maxTextMessageBufferSize" value="9000"/> 
  <property name="maxBinaryMessageBufferSize" value="9000"/> 
</bean>
