我正在尝试在我的 maven 项目中配置这个http://svn.apache.org/viewvc/commons/proper/dbcp/trunk/doc/PoolingDriverExample??.java?view=markup 示例。因此，我必须将 j2ee.jar 添加到我的类路径中。但是如果我在 pom.xml 中添加了上面的内容，那么我会收到一些错误，因为 ConnectionFactory 无法解析为类型

You can check for transitive dependencies using the maven dependency plugin. Just do an
您可以使用 maven 依赖插件检查传递依赖。做一个
mvn dependency:tree

The repo you specified does not provide that version:6.0
您指定的回购不提供该版本：6.0

You may want to use http://repo1.maven.org/maven2which does provide the resource and version you specified.
您可能希望使用http://repo1.maven.org/maven2，它确实提供了您指定的资源和版本。
Also, your scope should be "provided". Having a runtime scope tells maven that the dependency is needed for runtime but not compilation. You need the opposite. Your dependency is needed for compilation but not runtime because it's "provided" by the container. See http://maven.apache.org/pom.htmlfor more details.
此外，您的范围应该是“提供”的。拥有运行时范围告诉 Maven 运行时需要依赖项，但不需要编译。你需要相反的。编译需要依赖项，但运行时不需要依赖项，因为它是由容器“提供”的。有关更多详细信息，请参阅http://maven.apache.org/pom.html。
