Azure Service Fabric 资源管理器中的 Java Web 应用程序部署

Question

我们有一个无状态 Java 应用程序，我想将其部署在 Azure 结构中。我已经按照文档安装了 Fabric SDK 和 Visual studio 工具。

之后，我创建了 Service Fabric 应用程序“ guest 可执行文件”模板，我的项目结构如下所示:

我已按照与 https://azure.microsoft.com/en-us/documentation/articles/service-fabric-deploy-existing-app/ 中的文档类似的步骤进行操作

我的 ServiceManifest.xml 如下:

<?xml version="1.0" encoding="utf-8"?>
<ServiceManifest Name="Guest1Pkg"
                 Version="1.0.0"
                 xmlns="http://schemas.microsoft.com/2011/01/fabric"
                 xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <ServiceTypes>
    <StatelessServiceType ServiceTypeName="Guest1Type" UseImplicitHost="true" />
  </ServiceTypes>
  <CodePackage Name="Code" Version="1.0.0">
    <EntryPoint>
      <ExeHost>
        <Program>HelloWorld.war</Program>
        <Arguments></Arguments>
        <WorkingFolder>CodePackage</WorkingFolder>
      </ExeHost>
    </EntryPoint>
  </CodePackage>
  <ConfigPackage Name="Config" Version="1.0.0" />
  <Resources>
    <Endpoints>
      <Endpoint Name="JavaAppTypeEndpoint" Protocol="http" Port="8080" Type="Input" />
    </Endpoints>
  </Resources>
</ServiceManifest>

我的 ApplicationManifest.xml 片段如下:

<?xml version="1.0" encoding="utf-8"?>
<ApplicationManifest ApplicationTypeName="Application1Type"
                     ApplicationTypeVersion="1.0.0"
                     xmlns="http://schemas.microsoft.com/2011/01/fabric"
                     xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <Parameters>
    <Parameter Name="Guest1_InstanceCount" DefaultValue="-1" />
  </Parameters>
  <ServiceManifestImport>
    <ServiceManifestRef ServiceManifestName="Guest1Pkg" ServiceManifestVersion="1.0.0" />
    <ConfigOverrides />
  </ServiceManifestImport>
  <DefaultServices>
    <Service Name="Guest1">
      <StatelessService ServiceTypeName="Guest1Type" InstanceCount="[Guest1_InstanceCount]">
        <SingletonPartition />
      </StatelessService>
    </Service>
  </DefaultServices>
</ApplicationManifest>

我在本地部署到 Service Fabric Explorer，构建和发布步骤良好，没有任何错误:

但是应用程序运行状况显示错误，事件为

"Error event: SourceId='System.Hosting', Property='CodePackageActivation:Code:EntryPoint'.
There was an error during CodePackage activation."

我不知道部署中可能存在什么问题，除了上面提到的之外是否还需要在应用程序服务入口点中包含任何内容。

此外，部署在独立 tomcat 上的 Java Web 应用程序具有以下上下文 http://localhost:8080/HelloWorld/hello 。如果应用程序部署在 Service Fabric 集群中，则其 URL 上下文是否保持不变，或者应该类似于 http://localhost:8080/Application1/Guest1/HelloWorld/hello由于它周围有 Azure 织物包装？

Answer 1

最后发现我们需要在Host虚拟机(Azure VM或本地桌面)中单独安装Java，然后我们必须引用java路径。

所以我的服务 list 是

<EntryPoint>
      <ExeHost>
        <Program>scripts\launchConfig.cmd</Program>
        <Arguments></Arguments>
        <WorkingFolder>CodePackage</WorkingFolder>
        <ConsoleRedirection FileRetentionCount="5" FileMaxSizeInKb="2048"/>
      </ExeHost>
</EntryPoint>

我在Code文件夹下创建了一个名为scripts的文件夹，脚本文件“launchConfig.cmd”只有一行，如下所示:

"C:\Program Files (x86)\Java\jre1.8.0_101\bin\java.exe" -jar HelloWorld.war

我们可能需要删除路径硬编码，但这就是它最终引用的方式。
