问题：Buffer pool was not set on WebSocketDeploymentInfo

我的项目实用SpringBoot2.4.9，Undertow使用的也是2.4.9，启动时，控制台出现以下警告提示：
WARN main io.undertow.websockets.jsr UT026010: Buffer pool was not set on WebSocketDeploymentInfo, the default pool will be used

在这里插入图片描述

问题解决

添加以下配置类代码：

import io.undertow.server.DefaultByteBufferPool;
import io.undertow.websockets.jsr.WebSocketDeploymentInfo;
import org.springframework.boot.web.embedded.undertow.UndertowServletWebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.stereotype.Component;

/**

 * @description: 解决启动io.undertow.websockets.jsr UT026010: Buffer pool was not
 *   set on WebSocketDeploymentInfo, the default pool will be used的警告
 */
@Component
public class CustomizationBean implements WebServerFactoryCustomizer<UndertowServletWebServerFactory> {
    @Override
    public void customize(UndertowServletWebServerFactory factory) {
        factory.addDeploymentInfoCustomizers(deploymentInfo -> {
            WebSocketDeploymentInfo webSocketDeploymentInfo = new WebSocketDeploymentInfo();
            webSocketDeploymentInfo.setBuffers(new DefaultByteBufferPool(false, 1024));
            deploymentInfo.addServletContextAttribute("io.undertow.websockets.jsr.WebSocketDeploymentInfo", webSocketDeploymentInfo);
        });
    }
}

以上代码相当于给容器设置了默认的1024的Buffer pool ，完成后启动则不再报之前的警告提示。
