尝试做一个类似于以下功能的示例。每当尝试调用“ CHANGECONTRAST_URL”时，我都尝试广播base64图像。每当我尝试多次执行该功能时（大约同时执行100次）。我收到以下错误
@MessageMapping(CHANGECONTRAST_URL)
public void onChangeContrast(float offset) {//throws InterruptedException{
String base64 =/*function to get base64 of 150kb image*/;
template.convertAndSend(GET_IMAGE_URL, base64);
}
//我收到错误
