如何从我的应用程序访问 MSI public 属性？

Question

我正在通过 javafxpackager 使用 Wix 为我的 Java (8) 应用构建 MSI 安装程序。安装的时候我可以传命令行属性，比如：

msiexec /i app.msi FOO=BAR

如何从我自己的应用程序访问 FOO 的值？

我已经有一个 javafxpackager 正在获取的自定义 wxs 文件 (src/main/deploy/package/windows/<<APPNAME>>.wxs)，它看起来像这样

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
     xmlns:util="http://schemas.microsoft.com/wix/UtilExtension">
    <Product Id="PRODUCT_GUID" Name="APPLICATION_NAME"
             Language="1033" Version="APPLICATION_VERSION"
             Manufacturer="APPLICATION_VENDOR"
             UpgradeCode="PUT-GUID-HERE">
        <Package Description="APPLICATION_DESCRIPTION" Comments="None"
                 InstallerVersion="200" Compressed="yes"
                 InstallScope="INSTALL_SCOPE" Platform="PLATFORM"/>
        <Media Id="1" Cabinet="simple.cab" EmbedCab="yes"/>

        <!-- We use RemoveFolderEx to ensure application folder is fully
             removed on uninstall. Including files created outside of MSI
             after application had been installed (e.g. on AU or user state).

             Hovewer, RemoveFolderEx is only available in WiX 3.6,
             we will comment it out if we running older WiX.

             RemoveFolderEx requires that we "remember" the path for uninstall.
             Read the path value and set the APPLICATIONFOLDER property with the value.
        -->
        <Property Id="APPLICATIONFOLDER">
            <RegistrySearch Key="SOFTWARE\APPLICATION_VENDOR\APPLICATION_NAME"
                            Root="REGISTRY_ROOT" Type="raw"
                            Id="APPLICATIONFOLDER_REGSEARCH" Name="Path"/>
        </Property>
        <DirectoryRef Id="APPLICATIONFOLDER">
            <Component Id="CleanupMainApplicationFolder" Guid="*" Win64="WIN64">
                <RegistryValue Root="REGISTRY_ROOT"
                               Key="SOFTWARE\APPLICATION_VENDOR\APPLICATION_NAME"
                               Name="Path" Type="string" Value="[APPLICATIONFOLDER]"
                               KeyPath="yes"/>
                <!-- We need to use APPLICATIONFOLDER variable here or RemoveFolderEx
                     will not remove on "install". But only if WiX 3.6 is used. -->
                WIX36_ONLY_START
                <util:RemoveFolderEx On="uninstall" Property="APPLICATIONFOLDER"/>
                WIX36_ONLY_END
            </Component>
        </DirectoryRef>
        <?include bundle.wxi ?>
        UI_BLOCK

        <Icon Id="DesktopIcon.exe" SourceFile="APPLICATION_ICON"/>

        <Property Id="ARPPRODUCTICON" Value="icon.ico"/>
    </Product>
</Wix>

您可以在安装期间将任何 public 属性（大写）写入注册表，然后您可以在运行时使用常规注册表访问机制（无论构造什么）从您的应用程序中读回该值你的开发语言支持）。

属性不会自动保存到注册表中，您需要自己将它们添加到注册表中。也许查看 The WiX toolset's "Remember Property" pattern.

您需要添加：

<RegistryValue Root="HKLM" 
               Key="SOFTWARE\APPLICATION_VENDOR\APPLICATION_NAME"                                
               Name="Foo" Type="string" Value="[FOO]"/>

和

<Property Id="FOO">
    <RegistrySearch Id="Foo"
                    Root="HKLM"
                    Key="SOFTWARE\APPLICATION_VENDOR\APPLICATION_NAME"
                    Name="Foo" Type="raw"/>
</Property>

到 .wxs 文件。这将负责在注册表中记录属性并在升级时记录 re-saving。
