Vaadin，战争，tomcat-生产模式-javax.servlet.ServletException：未在Jetty上运行，JSR-356支持不可用

标签： gradle vaadin tomcat9

我通过gradle以生产模式构建了Vaadin项目。

在这里build.gradle.kts 

plugins {
    kotlin("jvm") version "1.3.20"
    id("com.github.johnrengelman.shadow") version "4.0.3"
    id("com.devsoap.vaadin-flow") version "1.0"
    id("org.gretty") version "2.3.1"
    id("war")
}

val kotlinVersion = "1.3.20" //by extra("1.3.20")
val jettyVersion = "9.4.14.v20181114"
val vaadinVersion = "12.0.4"

val jettyDep = { dep: String, suffix: String ->
    "org.eclipse.jetty${if (suffix.isNotEmpty()) ".$suffix" else suffix}:$dep:$jettyVersion"
}

vaadin.autoconfigure()

vaadin {
    setProductionMode(true)
}

dependencies {
    implementation(kotlin("stdlib-jdk8"))
    implementation("com.github.jengelman.gradle.plugins:shadow:4.0.3")
    implementation("org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion")
    implementation("com.vaadin:vaadin-bom:$vaadinVersion")
    implementation("com.vaadin:vaadin-core:$vaadinVersion")
    //implementation("com.vaadin:flow-server-production-mode:1.4.0") // Switch to production mode
    implementation("com.github.mvysny.karibudsl:karibu-dsl-v10:0.6.2")
    implementation("ch.qos.logback:logback-classic:1.2.3")
    implementation("javax.servlet:javax.servlet-api:3.1.0")
    implementation(jettyDep("jetty-plus", ""))
    implementation(jettyDep("jetty-continuation", ""))
    implementation(jettyDep("jetty-server", ""))
    implementation(jettyDep("websocket-server", "websocket"))
    implementation(jettyDep("javax-websocket-server-impl", "websocket"))
    implementation("com.auth0:java-jwt:3.7.0")
    implementation("org.reflections:reflections:0.9.11")

}

通过命令成功创建生产模式战争：

gradlew assemble

好。 但是当我向Tomcat 9部署战争时，我得到了错误：

我认为您的dependencies列表中的Jetty条目会导致Jetty类最终进入.war并因此也进入类路径。其中一些类具有一些通用的Servlet API注释，这些注释由Tomcat拾取，Tomcat会尝试在服务器启动期间进行初始化。
