  可以去本地仓库看一下下载到了相应的包没有，看看下载到的包有没有问题，要是有问题就删了重新下，还是不行就到maven dependencies里面看看有没有加到项目里来，没有就加一下

  在maven里面处理一致不可以，可以通过build path -> libraries里面添加这个jar包，就可以了

  原因：缺少dom4j的jar包

  解决方法：引入dom4j.jar

  <!-- https://mvnrepository.com/artifact/dom4j/dom4j -->

  <dependency>

      <groupId>dom4j</groupId>

      <artifactId>dom4j</artifactId>

      <version>x.x.x</version>

  </dependency>
