故障原因:
JAXB API是java EE 的API，因此在java SE 9.0 中不再包含这个 Jar 包。 java 9 中引入了模块的概念，默认情况下，Java SE中将不再包含java EE 的Jar包 而在 java 6/7 / 8 时关于这个API 都是捆绑在一起的
解决问题1:
降低JDK 版本到 JDK 8
解决问题2:手动加入这些依赖Jar包
<dependency> <groupId>javax.xml.bind</groupId> <artifactId>jaxb-api</artifactId> <version>2.3.0</version> </dependency> <dependency> <groupId>com.sun.xml.bind</groupId> <artifactId>jaxb-impl</artifactId> <version>2.3.0</version> </dependency> <dependency> <groupId>com.sun.xml.bind</groupId> <artifactId>jaxb-core</artifactId> <version>2.3.0</version> </dependency> <dependency> <groupId>javax.activation</groupId> <artifactId>activation</artifactId> <version>1.1.1</version> </dependency>
真正解决方案：java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter
