教程 有一段时间没有更新了.本教程仍然引用 JDOM1，而较新版本的 Spring Web 服务仅支持 JDOM2.

The tutorial hasn't been updated for a while. The tutorial still references JDOM1 whereas newer versions of Spring Web Services only support JDOM2.

<dependency>
    <groupId>jdom</groupId>
    <artifactId>jdom</artifactId>
    <version>1.0</version>
</dependency>

改为

<dependency>
    <groupId>org.jdom</groupId>
    <artifactId>jdom</artifactId>
    <version>2.0.2</version>
</dependency>

并将 org.jdom 导入更改为 org.jdom2.

And change the org.jdom imports to org.jdom2.
