Vaadin 24 WEB Push用Undertow替换Tomcat

我想在Vaadin取代Tomcat。想用Under / Jetty / Netty替换它。目前我使用 Spring Boot 和取代雄猫与暗流。不幸的是，此设置禁用了Vaadin中的WEB_PUSH。有什么办法可以解决这个问题吗？或者是一种在vaadin中替换tomcat的方法？或者让vaadin webpush与undertow / netty / jetty一起工作？我真的需要更轻便的东西。雄猫很重。
如果我将tomcat替换为undertow，就会出现以下错误：

这表明

@Push(PushMode.AUTOMATIC,transport = Transport.WEBPUSH)

不行，我想让这和暗流一起工作

Tomcat不在Vaadin中，而是在Sping Boot 中。您可以使用Sping Boot 参考手册中的说明将Tomcat替换为例如。不是说 spring-boot-starter-web 依赖不一定直接在你的pom.xml中，但是它是由Vaadin依赖传递进来的。我尝试将以下代码段添加到基本的Vaadin 24.1项目中，之后使用Undertow而不是Tomcat，服务器推送对我来说很好：

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <!-- Exclude the Tomcat dependency -->
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-undertow</artifactId>
    </dependency>
