阔叶 Jboss 设置 ClassNoFound

Question

尝试进行阔叶 Jboss 设置时，出现以下错误

我检查了源代码 com.broadleafcommerce.customersegment.admin.dataimport.persistence.CustomerSegmentRecordPersistencePreProcessor 在broadleaf-merchandising-group-1.2.1-GA.jar 中可用，但奇怪的是com.broadleafcommerce.dataimport.service 类。 RecordPersistencePreProcessor 找不到，请帮忙。

您遇到的问题是 Servlet 3.0+ 容器中的 ServletContextInitializer 扫描。在 Tomcat 中，您可以使用以下指南进行控制：https://wiki.apache.org/tomcat/HowTo/FasterStartUp#JAR_scanning。 Jboss 正在利用其类加载器来检查 ServletContextInitializer 类，并且在一些 Broadleaf jar 中，我们在编译时链接了一些在运行时可能不可用的条件类。

您使用的是基于 Broadleaf 5.2.x 的 Spring Boot 项目吗？您可以尝试添加一个带有空 <absolute-ordering /> 的 web.xml：https://www.broadleafcommerce.com/docs/core/current/broadleaf-concepts/key-aspects-and-configuration/app-server-configuration/using-a-web.xml

我也会质疑 Jboss 的使用。在 Spring 应用程序中使用成熟的 JEE 应用程序服务器的理由几乎为零，坦率地说，随着时间的推移，您会要求更多的问题。您正在尝试将胖 .war（使用 Maven 构建的 Spring 应用程序）与胖应用服务器 (jboss) 结合起来。您应该将胖 .war 文件与轻量级 servlet 容器（如 Tomcat）或轻量级 .war 文件（JEE 应用程序）与 JEE 应用程序服务器配对。
