Question

我正在尝试开发一个使用带有stax-api的库作为依赖项的应用程序。构建为独立应用程序它工作正常，但当我尝试使用JCL加载在我的应用程序中组装的依赖项的JAR时，我收到以下错误：

这很奇怪，这个类被组装到JAR中，我可以在归档中找到它。

在应用程序服务器库加载应用程序服务器库之前，我已经看到过这种消息。通常有一个设置允许您指定逆序。如果您正在使用Weblogic，可以通过在weblogic.xml文件中插入以下定义来实现：

<container-descriptor>
  <prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>

尝试添加此 Maven 依赖项：

<dependency>
    <groupId>stax</groupId>
    <artifactId>stax</artifactId>
    <version>1.2.0</version>
</dependency>

使用JCL找不到提供者com.bea.xml.stream.MXParserFactory
