jaxb-core和jaxb-impl有什么区别

Question

在什么情况下我需要在jaxb-implvsjaxb-core之间进行选择？在我的项目中同时拥有jaxb-impl和jaxb-core会导致任何类加载冲突吗？

Answer 1

如果您使用com.sun.xml。Maven Central中的bind＜/code＞工件（似乎＜code＞jaxb核心＜/code>是＜code>jaxb-impl＜/code｝、＜code>jaxb-xjc＜/code>和＜code>jaxb-jxc＜/cod>的底层（共享）依赖项）；因此，需要jaxb-core才能使用jaxb-impl。
