Java Azure 服务架构资源管理器中的 Webapp 部署

Java Webapp Deployment in Azure Service fabric explorer

我们有一个无状态的 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 Executable" 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,构建和发布步骤都很好,没有任何错误:

但是应用程序健康状态显示错误并且事件是

"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,Java web 应用程序在独立 tomcat 上部署时具有以下上下文 http://localhost:8080/HelloWorld/hello . If the Application is deployed in Service fabric cluster, will the URL context for this remains same or should it be something like http://localhost:8080/Application1/Guest1/HelloWorld/hello 由于围绕它的 Azure 结构包装器?

您在程序配置中放置的内容必须是可执行的(.exe、.cmd 等)。 Service Fabric 将尝试执行您放入其中的任何内容。

例如,在您链接到的文档中,要执行 node.js 应用程序,程序是 node.exe 并且参数指向应用程序:

<ExeHost>
  <Program>node.exe</Program>
  <Arguments>bin/www</Arguments>
  <WorkingFolder>CodePackage</WorkingFolder>
</ExeHost>

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。

所以我的服务清单是

<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,但这是最终引用的方式。

入口点应该是一个命令。 HelloWorld.war 不是命令。来宾可执行文件专为 运行 命令或 exe 而设计。

<SetupEntryPoint>
     <ExeHost>
         <Program>scripts\launchConfig.cmd</Program>
     </ExeHost>
  </SetupEntryPoint>

和 launchConfig.cmd 应包含 运行 Tomcat 或 jboss(或任何 j2ee 应用程序服务器)的脚本。您应该在 运行 服务器之前安装 java,配置 tomcat/ jboss,部署 HelloWorld.war 并配置端口。

如之前的回答所述,一种方法是将 Java 单独安装到机器上。

我在 https://blog.vjrantal.net/2017/04/11/high-availability-java-hosting-in-azure-using-service-fabric/ 上写了另一种方法,它基于将需要的 Java 运行时打包到应用程序包中。
