JAXB ClassNotFoundException使用Java 11构建Spring Boot App 2.2.0 _exception

赋料扬雄敌，诗看子建亲。这篇文章主要讲述JAXB ClassNotFoundException使用Java 11构建Spring Boot App 2.2.0相关的知识，希望能为你提供帮助。
我使用版本2.2.0.BUILD-SNAPSHOT和java 11（下面的POM）创建了一个Spring Boot应用程序：

当应用程序启动时，它会抛出此异常：

答案从Java 9开始，JAXB实现已被删除。所以你添加的只是API，你还需要添加实现。可能有几种选择。
作为一个你可以添加的修复 - 例如，我猜也有其他实现 - 这种依赖：

< dependency> < groupId> org.eclipse.persistence< /groupId> < artifactId> org.eclipse.persistence.moxy< /artifactId> < version> 2.7.3< /version> < /dependency>

Here是一个很好的解释。
为什么删除它（摘自上面的链接）：

Java的标准库并不是那么小巧轻便。在过去20多年的过程中，已经添加了许多功能，主要是因为当时认为如果Java支持开箱即用的特定技术将是一个好主意。
其中之一是对基于XML的Web服务的支持。当Java SE 6于2006年12月发布时，基于XML的Web服务很受欢迎，因此Java语言的开发人员认为，如果Java支持将Web服务作为标准功能进行调用，那将是一个好主意。决定将最初作为Java EE的一部分开发的必要API添加到Java SE。其中包括JAX-WS（基于XML的Web服务的Java API）和JAXB。
随着当今微服务的发展趋势，Java运行时环境小巧轻便非常重要，因此拥有一个内置支持所有可能技术的大型运行时库不再具有优势。
【JAXB ClassNotFoundException使用Java 11构建Spring Boot App 2.2.0】因此，在JEP-320中提出了从JDK中删除Java EE和CORBA模块的提议。
