webSocketMaxTextMessageSize property
The largest text message a WebSocket session accepts, in bytes; 8 KB
by default (Tomcat's default in Spring), -1 for no limit. A larger
message is not read: the session is closed with 1009 (message too
big). This starter's own key; Spring sets it on the container
(ServletServerContainerFactoryBean).
Implementation
final int webSocketMaxTextMessageSize;
