java⽤dom4j解析带有cdata的xml报⽂
背景
解决⽅法
按照节点格式⽣成对应的实体类
解析类
注意
使⽤xstream需要引⼊3个jar包
总结
背景
前两天在⼯作中，调⽤外部的webservice接⼝，发现对⽅的返回报⽂格式与常见的不同，在解析中也⼀直有问题，遂记录下来。
报⽂格式
1
success
张三
男
18
80

]]>
思路
可以发现在整个xmj报⽂的中间，有⼀部分数据⽤包裹起来，导致我们不能⽤以前的⽅法来解析，需要先去掉xml报⽂头，定位到return节点，再处理cdata中的数据。
解决⽅法
按照节点格式⽣成对应的实体类
先⽣成实体类，需要lombok

// 此处初始化XStream加了new DomDriver()，因为缺少xpp3_min的jar包，如果有这个jar不加new DomDriver()也可以XStream xStream = new XStream(new DomDriver());
