我正在使用 swing 和 spring 来创建一个桌面应用程序。一切进展顺利，但是当我使用 eclipse JUNO 创建 jar 时，尝试在 cmd上将其作为java -jar myjar.jar运行时出现此错误。不知道问题出在哪里，求大神帮忙？

这是我的文件夹结构

 - myclasses
 - images
 - lib
 - META-INF
 + MANIFEST.MF
   - applicationContext.xml
 - build.xml

这是我的所有弹簧罐的MANIFEST.MF，包括：spring-context-support-3.2.0.M1.jar和spring-context-3.2.0.M1.jar

Manifest-Version: 1.0

中的Class-Path指令MANIFEST.MF没有按预期工作。我建议您将One-JAR与 Ant 或 Maven 结合使用，将您的应用程序及其所有依赖项打包到一个 JAR 中。我一直在使用这种方法，因为天知道有多久 - 完美无瑕。
