【问题讨论】：

这能回答你的问题吗？ javax.xml.bind.JAXBException Implementation of JAXB-API has not been found on module path or classpath

【参考方案1】：

我通过网站搜索解决了！

我们应该将这些代码添加到 POM.XML

  <dependency>
    <groupId>javax.activation</groupId>
    <artifactId>activation</artifactId>
    <version>1.1</version>
  </dependency>

  <dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
  </dependency>
