使用 Spring boot + gradle、Jetty 错误部署 AppEngine Flexible

Question

我有一个 Google App Engine Flexible 使用 gradle 和 spring 启动的应用程序。我的 build.gradle 文件如下：

buildscript {
repositories {
    mavenCentral()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.5.RELEASE")
    classpath 'io.spring.gradle:dependency-management-plugin:0.6.1.RELEASE'
    classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.5.RELEASE")
    classpath 'com.google.cloud.tools:appengine-gradle-plugin:+'    // latest App Engine Gradle tasks       
    }
}
    apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'war'
apply plugin: 'com.google.cloud.tools.appengine'  // App Engine tasks
war {
    baseName = 'gs-accessing-mongodb-data-rest'
    version =  '0.1.0'
}
repositories {
    mavenCentral()
}
configurations {
    providedRuntime
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
    providedCompile group: 'javax.servlet', name: 'servlet-api', version:'2.5'
    compile 'com.google.appengine:appengine:+'
    compile("org.springframework.boot:spring-boot-starter-data-rest")
    compile("org.springframework.boot:spring-boot-starter-data-mongodb")    
    //compile("org.springframework.boot:spring-boot-starter-web")  
    compile("org.springframework:spring-webmvc:4.2.3.RELEASE")
    compile("org.springframework:spring-tx:4.2.3.RELEASE")  
    testCompile("org.springframework.boot:spring-boot-starter-test") 
    compile("javax.servlet:jstl:1.2")
    //compile("javax.servlet:javax.servlet-api:2.5")
    compile("javax.servlet:servlet-api:2.5")  
    compile("org.codehaus.jackson:jackson-mapper-asl:1.9.13")
    compile("com.fasterxml.jackson.core:jackson-databind:2.5.3")
    compile("com.fasterxml.jackson.core:jackson-core:2.5.3")
    compile("commons-fileupload:commons-fileupload:1.3.1")
    compile("commons-io:commons-io:2.4")
    testCompile("junit:junit")
    providedRuntime 'org.apache.tomcat.embed:tomcat-embed-jasper'
    compile 'org.mongodb:mongo-java-driver:3.2.2'    
}
appengine {  // App Engine tasks configuration
  deploy {   // deploy configuration
    stopPreviousVersion = true  // default - stop the current version
    promote = true              // default - & make this the current version
  }
}
group = 'com.acin.shelfcheck'   // Generated output GroupId
version = '1.0-SNAPSHOT'          // Version in generated output
eclipse {
    project.natures 'org.eclipse.buildship.core.gradleprojectnature'
}

当我尝试在 Google AppEngine Flexible 中部署我的应用程序时，出现以下错误：

我的 gradle 文件哪里弄错了？

Answer 1

您的应用程序中设置了 2 个容器。

org.apache.tomcat.websocket.server.WsServerContainer

这在 Jetty 上是不可能的。

查找具有 class org.apache.tomcat.websocket.server.WsSci 的 jar 文件，您要么必须将其替换为非 Tomcat 特定的内容，要么将其删除。

Answer 2

正如 Joakim 所解释的删除 org.apache.tomcat.websocket.server.WsSci 我已经排除了 tomcat 因为它已在 link 中解释如下：

Maven 中的示例：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <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-jetty</artifactId>
</dependency>

Gradle中的示例：

    configurations {
compile.exclude module: "spring-boot-starter-tomcat"
}
dependencies {
    compile("org.springframework.boot:spring-boot-starter-web:1.5.2.RELEASE")
    compile("org.springframework.boot:spring-boot-starter-jetty:1.5.2.RELEASE")
    // ...
}

Answer 3

我遇到了同样的问题，解决方法如下。

创建 ServletInitializer.java（用于部署更改 jar -> war）
- Spring Boot packaging the project to War
修改build.gradle
- 添加依赖项 graprovidedRuntime('org.springframework.boot:spring-boot-starter-tomcat')

build.gradle

中的示例

buildscript {
    ext {
        springBootVersion = '2.0.3.RELEASE'
    }
    repositories {
        jcenter()
        mavenCentral()
    }

    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath 'com.google.cloud.tools:appengine-gradle-plugin:2.0.0-rc3'
    }
}

apply plugin: 'java'
apply plugin: 'war'  
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'com.google.cloud.tools.appengine'



repositories {
    mavenCentral()


}

group   = "yourProjectID"        // Generated output GroupId
version = "1.0-SNAPSHOT"       // Version in generated output

sourceCompatibility = 1.8
targetCompatibility = 1.8

appengine {
    deploy {
        version = "GCLOUD_CONFIG"
        projectId = "GCLOUD_CONFIG"
    }
}

dependencies {

    compile("org.springframework.boot:spring-boot-starter-web")

     ....

    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
}
