java.lang.NoClassDefFoundError：javax/xml/bind/annotation/XmlElement

Question

我正在尝试将我的项目从 java8 迁移到新的 java21。 我正在使用 Hibernate 6.44，并且我面临 jaxb 类的问题。

我已经尝试使用这些部分调整我的 pom.xml 文件：

        <!-- https://mvnrepository.com/artifact/jakarta.xml.bind/jakarta.xml.bind-api -->
        <dependency>
            <groupId>jakarta.xml.bind</groupId>
            <artifactId>jakarta.xml.bind-api</artifactId>
            <version>4.0.1</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.glassfish.jaxb/jaxb-runtime -->
        <dependency>
            <groupId>org.glassfish.jaxb</groupId>
            <artifactId>jaxb-runtime</artifactId>
            <version>4.0.4</version>
        </dependency>

但仍然有问题。

每次运行代码时我都会得到：

查了很多资料都没有找到解决办法。

如果有人能帮助我使其工作，我将不胜感激。

谢谢！
