Question

在GAE中部署测试Maven Spring Boot REST应用时，我遇到了以下错误-

[错误]无法在项目PublicLibrary上执行目标com.google.cloud.tools:appengine-maven-plugin:2.0.0-rc5:deploy（default-cli）：App Engine应用程序部署失败：com .google.cloud.tools.appengine.operations.cloudsdk.process.ProcessHandlerException：com.google.cloud.tools.appengine.AppEngineException：非零退出：2-> [帮助1]

App.yaml看起来像

runtime: java
env: flex
runtime_config:
  jdk: openjdk8
env_variables:
  SPRING_PROFILES_ACTIVE: "gcp"
handlers:
- url: /.*
  script: this field is required, but ignored
manual_scaling: 
  instances: 1

Answer 1

检查Google Cloud Platform的官方Springboot sample，以了解您可能会做些什么。

例如，我看到在部分中，它需要和 < / strong>：

<properties> <java.version>1.8</java.version> <maven.compiler.source>${java.version}</maven.compiler.source>  <maven.compiler.target>${java.version}</maven.compiler.target>  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <appengine.maven.plugin>1.3.2</appengine.maven.plugin> </properties>

请注意，appengine-maven-plugin使用的是版本 2.0.0-rc5 ，因此，如果将其添加到上述属性中，则应使用与插件部分相同的版本：

<plugin> <groupId>com.google.cloud.tools</groupId> <artifactId>appengine-maven-plugin</artifactId> <version>${appengine.maven.plugin}</version> </plugin>

Answer 2

谢谢。我遵循了示例应用程序，并将差异添加到我的pom.xml中。仅此一项并不能解决问题。此外，我将遗留的运行状况检查添加到允许部署该应用的app.yaml中（花费了相当长的时间）- 健康检查： enable_health_check：是 check_interval_sec：5 timeout_sec：4 不健康阈值：2 Healthy_threshold：2

但是在部署后，当我尝试以 https：// ：appspot.com 访问该应用程序时，我得到以下错误-

错误：服务器错误服务器遇到临时错误，无法完成您的请求。请在30秒内重试。

更新我将资源部分添加到app.yaml中，因为在GAE中，已知this article

中标识的Java会消耗大量内存

resources:
  cpu: 2
  memory_gb: 2.3
  disk_size_gb: 10
  volumes:
  - name: ramdisk1
    volume_type: tmpfs
    size_gb: 0.5

在Google AppEngine +非零退出2中部署Spring Boot应用程序时出错
