Install4j web应用程序作为服务自动更新，无需启动程序

install4j

Install4j web应用程序作为服务自动更新，无需启动程序,install4j,Install4j,如果应用程序是没有启动器的web应用程序作为服务，install4j中的自动更新功能是否有效？我尝试了很多在网络资源中提到的方法，但没有成功。请帮忙。我使用的是install4j Windows Edition 6.1.6 编辑1： @英戈·凯格尔， 根据您的建议，我添加了-Dinstall4j.keepLog=true-Dinstall4j.alternativeLogfile=E:/install4j log/log.txt，并获得了以下日志。请帮忙 [INFO] com.install4j

我建议升级到install4j 7，它有很多新的自动更新功能，可以很好地用于服务

使用install4j 7，您可以在安装程序->屏幕和操作步骤中添加“后台更新下载程序”应用程序。该应用程序模板中的关键操作是“计划更新安装”操作

在您的服务中，您可以按如下方式启动更新下载程序：


ApplicationLauncher.launchApplication("<ID>", null, true, null);


现在，您只需要触发已下载安装程序的执行。您可以立即这样做，如果不想终止服务，也可以在启动时这样做。您需要的代码段如下：


UpdateChecker.executeScheduledUpdate(Arrays.asList("-q"), false, null);


作为更新安装的一部分，服务将关闭。服务无法自动重启（如果您将
true
作为上述方法调用的第二个参数传递给GUI启动器，则GUI启动器可以自动重启），但必须使用“启动服务”操作启动服务，您可能已经在安装程序中执行了该操作

有关更多信息和屏幕截图，请参阅




然后搜索“后台自动更新”。
如果选择“显示ID”工具栏按钮，下载程序的ID就是安装程序->屏幕和操作步骤中更新下载程序名称旁边的ID。您提到的另一个ID（9244-5699-2766-7401）是项目的ID。您不必担心下载位置。请查看更新下载程序的日志文件以检查发生了什么。将VM参数
-Dinstall4j.keepLog=true-Dinstall4j.alternativeLogfile=/path/to/writable/log.txt
传递给更新下载程序（launchApplication
的第二个参数采用带参数的字符串数组），以便在特定路径中获取日志文件。然后，您必须编辑“设置变量”的脚本操作并添加如下调试代码
Util.logInfo（null，“分支1”）
以查看操作不返回更新描述符项的原因。要记录可用条目的版本，请执行
UpdateDescriptorEntry[]条目=（（UpdateDescriptor）context.getVariable（“UpdateDescriptor”））.getEntries（）；对于（UpdateDescriptorEntry:entries）{Util.logInfo（null，entry.getNewVersion（））；}
安装程序似乎正在使用32位JRE运行。您必须使用来自32位JDK的jstack，而不是来自64位JDK的jstack。安装程序具有必须选择的“允许无人参与模式”属性（默认情况下已选择），请检查该属性。如果使用相同的参数从命令行手动执行安装程序会怎么样？这样行吗？ 
ApplicationLauncher.launchApplication("<ID>", null, true, null);

UpdateChecker.isUpdateScheduled()

UpdateChecker.executeScheduledUpdate(Arrays.asList("-q"), false, null);
