报错：java.lang.NoClassDefFoundErro

首先说的是，亲测可行。

少jar包，找到pom.xml,引入依赖

<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>

赠予有缘人。
