在 Vaadin + Spring boot 项目中用 Undertow 替换 Tomcat - ERR_CONNECTION_CLOSED

Question

我想用 undertow 替换 Tomcat。 一切看起来都很好，但当我尝试连接到 Rest api 或 vaadin 视图时，没有错误和任何其他信息表明出现问题。只有浏览器给出错误：“ERR_CONNECTION_CLOSED”

build.gradle内容：

configurations.all {
    exclude group: 'org.springframework.boot', module:'spring-boot-starter-tomcat'
}


dependencies {
    implementation "com.vaadin:vaadin-core:$vaadinVersion"
    implementation "org.springframework.boot:spring-boot-starter-security:$springBootVersion"
    implementation("org.springframework.boot:spring-boot-starter-web:$springBootVersion") {
        exclude group: 'com.fasterxml.jackson.core'
        exclude group: 'com.fasterxml.jackson.datatype'
        exclude group: 'com.fasterxml.jackson.module'
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-tomcat'
        exclude module: 'spring-boot-starter-tomcat'
        exclude group: 'org.apache.tomcat.embed'
    }

    implementation("org.springframework.boot:spring-boot-starter-undertow:$springBootVersion")


    implementation ("org.springframework.boot:spring-boot-starter-parent:$springBootVersion") {
//        exclude module: 'spring-boot-starter-tomcat'
    }
    implementation "org.springframework.boot:spring-boot-starter-mail:$springBootVersion"
    implementation "org.springframework.boot:spring-boot-configuration-processor:$springBootVersion"
    implementation("com.vaadin:vaadin-spring-boot-starter:$vaadinVersion")
    implementation ("com.vaadin:vaadin-spring-boot-starter:$vaadinVersion")


    implementation ("com.vaadin:vaadin-bom:${vaadinVersion}") {
        exclude group: 'org.springframework.boot', module:'spring-boot-starter-tomcat'
    }

    implementation 'com.google.code.gson:gson:2.10.1'

    implementation "org.springframework.boot:spring-boot-starter-data-jpa:$springBootVersion"
   

}

控制台中没有错误或任何其他信息。无法访问 vaadin 视图和其余 api。当我切换回 tomcat 时，一切正常。 我怎样才能解决这个问题 ？我真的需要用 undertow 替换 tomcat。

Answer 1

我从 https://start.vaadin.com 下载了一个新项目，并更改了 build.gradle，如下所示。

更新

我还必须在 Vaadin 依赖项上排除 tomcat。

buildscript {
    repositories {
        mavenCentral()
        maven { setUrl("https://maven.vaadin.com/vaadin-prereleases") }
        }
}
plugins {
    id 'org.springframework.boot' version '3.1.5'
    id 'io.spring.dependency-management' version '1.0.15.RELEASE'
    id 'java'
    id 'com.vaadin'
}

repositories {
    mavenCentral()
    maven { setUrl("https://maven.vaadin.com/vaadin-prereleases") }
    maven { setUrl("https://maven.vaadin.com/vaadin-addons") }
}

configurations {
    developmentOnly
    runtimeClasspath {
        extendsFrom developmentOnly
    }
}

dependencies {
    implementation('com.vaadin:vaadin-spring-boot-starter') {
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-tomcat'
    }
    implementation('org.springframework.boot:spring-boot-starter-web') {
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-tomcat'
    }
    implementation('org.springframework.boot:spring-boot-starter-undertow')
    developmentOnly 'org.springframework.boot:spring-boot-devtools'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
}

dependencyManagement {
    imports {
        mavenBom "com.vaadin:vaadin-bom:$vaadinVersion"
    }
}
