java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter 解决方法

idea 我这里虽然电脑上安装的是jdk1.8，但是idea默认使用了jdk 11

方式1：降低jdk版本为1.8 （我这里使用了第一种方法）

 

 

方式2：手动引入相关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>

2022-01-12 第二种方式已验证可以使用

但是会爆以下错误，但是不影响程序的正常运行
