java - 如何从我的应用程序访问 MSI 公共(public)属性？

Question

我正在通过 javafxpackager 使用 Wix 为我的 Java (8) 应用程序构建 MSI 安装程序。安装时，我可以传递命令行属性，例如:

msiexec /i app.msi FOO=BAR

如何访问 FOO 的值来 self 自己的应用程序？

我已经有一个自定义wxs javafxpackager 正在拾取的文件 ( src/main/deploy/package/windows/<<APPNAME>>.wxs )，它看起来像这样

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"

        <Package Description="APPLICATION_DESCRIPTION" Comments="None"
                 InstallerVersion="200" Compressed="yes"

        <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.

                <!-- We need to use APPLICATIONFOLDER variable here or RemoveFolderEx
                     will not remove on "install". But only if WiX 3.6 is used. -->

您可以在安装过程中将任何公共(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(无论您的开发语言支持什么构造)从应用程序中读回该值。

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重新保存它。
