如何从应用程序访问MSI公共属性？

Question

我通过javafxpackager使用Wix为Java（8）应用程序构建MSI安装程序。 安装它时，我可以传递命令行属性，例如：

msiexec /i app.msi FOO=BAR

如何从自己的应用程序访问FOO的值？

我已经有一个javafxpackager可以拾取的自定义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

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

您可以在安装过程中将任何公共属性（UPPERCASE）写入注册表，然后可以使用常规注册表访问机制（无论开发语言所支持的结构）在运行时从应用程序中读取该值。

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。 也许看看WiX工具集的“记住属性”模式 。

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。 这样可以将属性记录在注册表中，并在升级时重新保存它。

从Java访问它的各种方法可以找到： 使用Java读/写Windows注册表。
