My Project structure is
  parent
     |---ejb-app.jar
     |---restapi-app.war
     |---ear-app.ear

我正在使用 commons-beanutils 将 JavaEntity Bean 映射到普通的 POJO 类（DTO）。commons-beanutils 的实现在 ejb-app.jar 中可用。

Example: BeanUtils.copyProperties(destination, source);

我的ear-app.ear aaplication 打包了ejb-app.jar & restapi-app.war 等两个模块。下面我添加了ear-app.ear的pom.xml

问题： 当我在 RedHat JBoss EAP7 服务器中部署我的应用程序时，我收到以下错误： 原因：java.lang.ClassNotFoundException: org.apache.commons.beanutils.BeanUtils from [Module "deployment.ear-app-0.0. 1-SNAPSHOT.ear.ejb-app-0.0.1-SNAPSHOT.jar:main" 来自服务模块加载器]
