解决：ClassNotFoundException: com.sun.xml.internal.bind.v2.ContextFactory

在使用JAXBContent对类与xml进行转换时报错：java.lang.ClassNotFoundException: com.sun.xml.bind.v2.ContextFactory

说明ContextFactory相关类找不到，可在POM文件中添加依赖：

<dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.3</version>
</dependency>
