我一直在寻找如何解决这个问题。我发现了类似的问题，并尝试了一切，但没有任何帮助。重新安装Java和gradle没有帮助。这里是错误的堆栈跟踪：

答案 0 :(得分：1)
我可以从日志中看到你正在使用带有Java 9的Spring Boot 1.5.2.Spring Boot 1.5.x不支持Java 9.你可以使用Java 8或升级到Spring Boot 2.0.0。如果采用后一种选择，则还必须使JAXB API可用。它默认提供在Java 8中，但不提供在Java 9中。提供它的一种方法是在build.gradle中添加这样的依赖项：
runtime "javax.xml.bind:jaxb-api"
没有必要在依赖项上指定版本，因为Spring Boot的依赖关系管理会为您处理。
您可以了解有关将Spring Boot与Java 9 here一起使用的更多信息。
