问题分析与解决方案 #

问题根源 #

错误栈里的java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException明确说明：运行时找不到JAXB的核心异常类。

你的项目使用的Hibernate 5.2.17.Final依赖JAXB来解析XML映射文件，但从Java 9开始，JAXB不再是JDK的默认内置模块，需要手动添加对应的Maven依赖才能正常运行。

解决步骤 #

1. 添加JAXB相关依赖：在你的pom.xml的<dependencies>节点中加入以下依赖：

<!-- JAXB API 核心依赖 -->
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.1</version>
</dependency>
<!-- JAXB 实现类（运行时需要） -->
<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.3.1</version>
    <scope>runtime</scope>
</dependency>
<!-- JAXB 辅助依赖（Java 9+ 需要） -->
<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>activation</artifactId>
    <version>1.1.1</version>
</dependency>

2. 修复pom中的重复配置：注意到你在<properties>里重复定义了servlet.version（同时写了3.1.0和3.0.1），建议删除其中一个，统一版本号，避免依赖冲突，比如保留<servlet.version>3.1.0</servlet.version>。

完成以上操作后，重新执行mvn clean install，部署项目后这个错误应该就能解决了。
