【问题描述】：

我正在尝试使用注释从 EJB 模块（我称之为“核心”）中的 Servlet 调用 Bean

@EJB
private DoSomethingLocal doSomething;

但是当我尝试部署 EAR 时出现此结果

我应该怎么做才能让它工作？

引起：java.lang.RuntimeException：WFLYSRV0177：获取类 fnx_webapp.servlets.Test 的反射信息时出错 ModuleClassLoader for Module \\"deployment.FeNiX-WebApp-1.0-SNAPSHOT.war \\" 来自服务模块加载程序引起：java.lang.NoClassDefFoundError: Lfnx_core/entities/DoShitLocal;原因：java.lang.ClassNotFoundException: fnx_core.entities.DoShitLocal from [Module \\\"deployment.FeNiX-WebApp-1.0-SNAPSHOT.war\\\" from Service Module Loader]\"}}"

【解决方案1】：

日志说什么，错误说什么，所以看起来你有错字，我是你的代码。 EAR 的所有部分都如此干净和构建
