java - WinRun4J - 无法加载库 jar

Question

我正在尝试使用 WinRun4J 将 Java 程序作为 Windows 服务执行。该服务已正确创建并运行，直到由于 ClassNotFoundException 而停止:

我怀疑 WinRun4J 没有加载 lib 文件夹中的 lib jar。我的应用程序工作目录是这样的:

application directory
     -> bin directory
     -> lib directory

主要应用程序 jar 位于 bin 文件夹中，其他 jar 位于 lib 文件夹中。这是我的 servico.ini 文件，由 WinRun4J 使用:

vm.version.min=1.6
single.instance=process
service.class=br.com.gep.sped.extrator.AppServico
service.id=AgenteWIN
service.name=Agente Win
service.description=Agente de extração dos dados SPED.
classpath.1=*.jar
classpath.2=../lib/*.jar
vmarg.1=-Xmn100M
vmarg.2=-Xms500M
vmarg.3=-Xmx500M

我在 classpath.2 中尝试了很多变体，但没有成功。
我做错了什么？

Answer 1

作为 Windows，您可能需要使用反斜杠而不是正斜杠

classpath.2=..\lib\*.jar

如果这还不够，请尝试添加

working.directory=.

确保根据正确的基目录解析相对路径。如果所有其他方法都失败，您可以使用 Class-Path 将 list 添加到主 JAR 文件中，该 Class-Path 枚举所有 ../lib/file.jar 文件，并完全删除 classpath.2 。

编辑:看到堆栈跟踪，WinRun4J 似乎没有正确设置线程上下文类加载器。尝试添加

Thread.currentThread().setContextClassLoader(
    AppServico.class.getClassLoader());

在实例化任何 Spring/CXF 相关内容之前，到 serviceMain 的顶部。
