推荐答案

Sun 人已经在 java 11 中移除了对 jaxb 包的直接访问.
这些依赖将代替它起作用.如果您面临休眠 NullPointerException 问题，同样的修复.

Sun people have remove directly access to jaxb package in java 11.
These dependency will work instead of it. Same fix if you are facing hibernate NullPointerException issue.

<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-core</artifactId>
    <version>2.3.0.1</version>
</dependency>
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.1</version>
</dependency>
<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.3.1</version>
</dependency>
<dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.25.0-GA</version>
</dependency>
