Java 服务包装器可执行可运行 Jar

Question

WrapperAppJar我将可执行的可运行 jar 文件包装为窗口服务。根据 Tanuki 软件网站上的教程，我将我的应用程序从 eclipse 导出为可执行 jar 文件，并尝试将其包装到 Windows 服务中。当我执行 java -jar smpp-portal -port 90 时，我的应用程序从 CLI 顺利运行。但是，使用 Wrapper 服务时，我遇到了一些错误。这是我的配置文件

有人可以帮助我吗？提前谢谢你

Answer 1

unhillbilly 有一个很好的观点。但实际上这并不是您所看到的错误的真正原因。基本上，您的 jar 文件中的 list 文件看起来不正确。

当您创建 jar 文件时，您可能正在将您的项目从 eclipse 中导出为可运行的 jar 并选择作为库处理以将所需的 jar 文件打包到生成的 jar 中...

所以通过这样做，Eclipse 正在使用类 JarRsrcLoader .

这个类实际上是您的可执行 jar 的主类，而不是您可能认为的主类。

JarRsrcLoader 需要在 list 文件中设置 2 个参数:Rsrc-Main-Class 和 Rsrc-Class-Path。

Rsrc-Main-Class 是您实际主类的类名。

Rsrc-Class-Path 是启动应用程序的类路径(jar 文件中包含所有包含的 jar 文件)。

您的 list 文件似乎缺少这 2 个属性。

因此您可以通过更改导出 jar 文件的方式来解决此问题，例如使用“在 jar 中提取所需的库”。另一种选择是将 2 个缺少的属性添加到您的 META-INF/manifest.mf 文件中。
