推荐答案

如果将Tomcat作为服务安装在Windows上，则可以检查注册表: HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Tomcat\[version]\InstallPath.

If Tomcat is installed as a service on Windows, you can check the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Tomcat\[version]\InstallPath.

要从Java读取注册表，您需要使用类似 JNA 之类的方法 Advapi32Util.registryGetKeys()和Advapi32Util.registryGetStringValue()可以提供帮助.
