我的情况是这样的，在本地运行访问一点问题都没有，但是部署在云服务器上后，访问救出了下面的报错。
遇到的问题：
java.lang.ClassNotFoundException:javax.xml.bind.DatatypeConverter
原因：
这有可能是因为SpringBoot项目结合jwt进行登录时出现的问题，因为jdk版本太高导致的。
解决方案
方案一：如果jdk版本是8以上的，就降低jdk版本
自己换的版本低点的jdk就可以了，jdk8即可
方案二：在maven中添加依赖
<dependency> <groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId> <version>2.3.1</version> </dependency>
方案三：在maven种添加依赖
<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>
因为javax.xml.bind在jdk8中有，但是在更高版本就没有了，所以我们加上就行了。
