Spring Boot Stomp WebSocket
Parece que estou enfrentando um problema que se depara com o limite de tamanho de 8k que o tomcat incorporado possui para stomp as mensagens do websocket.
Ao enviar uma mensagem do servidor para o cliente, estou recebendo o seguinte erro. Com base na documentação que li, parece que o tomcat tem um limite de 8k para mensagens enviadas por websockets, mas também li que o Stomp pode enviar mensagens parciais e fazer com que o cliente remonte-as, o que não parece estar acontecendo.
A mensagem nunca chega ao manipulador do lado do cliente, por isso estou bastante confiante de que o problema esteja no meu WebSocketConfig, mas parece que, independentemente do parâmetro que eu tentei, não posso superar o limite de tamanho A) de 8k mensagens e / ou B ) se estiver acima do limite do buffer, envie-o em pedaços de mensagens parciais.
Ambos os lados têm o seguinte código de erro
[code=1009, reason=The decoded text message was too big for the output buffer and the endpoint does not support partial messages]
Tenho certeza de que estou perdendo algo fácil, mas não consigo apontar o dedo. Qualquer olhar extra seria apreciado. Obrigado!
