我正在尝试设置tomcat服务器,使所有常见的spring jar都进入tomcat lib目录,因为我有很多web应用程序使用spring。然而,我的一个web应用程序也使用了带有quartaz jar的spring batch。当所有JAR都位于app1/web-INF/lib目录中时,这个web应用程序工作正常。然而,当我试图将所有常见的spring jar移动到tomcat/lib目录以及app1/WEB\u INF/lib中的spring batch和quartaz jar时,我发现了noclassdefFound错误。这是堆栈跟踪

由于应用程序上下文加载类。当我移动Spring-context.jar时,Spring-web.jarspring-context-support.jar.它开始工作。正如@Naveen Ramawat所建议的那样。上下文加载器不会从web-inf/class目录(子节点)加载类。因此,当我将这些jars移动到web-inf/lib子类时,能够从tomcat lib目录加载父类。
子类加载器可以找到父类加载器中加载的类,但父类加载器无法找到子类加载器加载的类。这里,spring类需要quartz类来创建bean,但失败了,因为quartz类是由子类加载器加载的。
问题内容: 我正在使用Eclipse,我需要能够将Java库(JAR文件)添加到Web应用程序的文件夹中。我该如何实现? 问题答案: 将jar文件添加到您的WEB-INF / lib文件夹中。 在Eclipse中右键单击您的项目,然后转到“构建路径>配置构建路径” 添加“ Web应用程序库”库 这将确保所有WEB-INF / lib jar都包含在类路径中。
根据这个问题,我创建了一个实现Catalina LifecycleListener类的类。 如何在Tomcat启动时运行脚本? 当我将JAR文件放置在webapps/root/web-inf/lib中时,Tomcat启动失败,出现类未找到的异常: java.lang.ClassNotFoundException:Net.Company.Tomcat.StartupEventHookListener
Web应用程序的WEB-Inf/lib目录是用于jar文件的,servlet容器(例如Tomcat)会自动将这些文件带入应用程序的类路径。对于Java9的模块化jar,这种机制如何工作(或者将来应该如何工作)有什么想法吗?这些提供了模块,用户必须在其中指定应用程序应该使用哪些包含/导出的模块/包。(旧的)类路径还有一个模块路径。 模块化的jar是否可以在没有任何进一步规范/配置的情况下工作,以便所
我在webapp/WEB-INF/lib/文件夹下添加了一个依赖项。 当我使用maven构建时,我希望在war中将它复制到WEB-INF/lib,而不是WEB-INF/classes/WEB-INF/lib。我正在寻找这是使用maven本身来完成的。 我已经在pom文件中提到了打包作为战争,但是依赖项没有被复制。我是不是在pom文件里漏掉了什么。我已经复制了下面的pom: 附上战争内容截图。
我是新手。与Gradle我有多个项目构建文件。大多数项目构建文件都经过了适当的配置,工作良好,并生成了正确的输出。我正在尝试将其中一个项目从ANT build转换为Gradle build。我能够编译Java文件,并且能够生成WAR归档。 我在生成的WAR文件中注意到的一件事是,WEB-INF/lib目录中包含了额外的JAR文件。当我从ANT build system构建项目时,只有很少的jar文
我正在创建一个(Minecraft)Forge mod,它使用(非官方的)Discord API JDA。我在EclipseIDE中这样做。 在IDE中,我可以添加带有依赖项的JDA,并且代码中没有错误。然后,使用gradlew并编译它,当我尝试运行它时(在Minecraft中)会出现一个错误。 我让几个人检查了我的身材。gradle要确保它是正确的,而且是正确的。我现在假设这是一个一般的Java
