Question

我收到错误;但是，我无法弄清楚为什么我会收到这个错误。第一个class元素不会给出任何错误，但第二个class元素会给出错误。（注意：我有其他映射，但它是重复相同的错误所以我不担心把整个文件放在一起）

“元素类型”class“的内容必须匹配

“（元*，子查询，缓存，同步*，评论，的tuplizer *，（ID |？？？？？复合-ID），鉴别，自然-ID，（版本|时间戳），（财产|？很多-to-一个|一到一个|分量|动态分量|特性|任何|地图|设为|列表|袋| idbag |阵列|原始阵列）的，（（合并，子类*）|加入子类* |？工会子*），装载机，SQL插入，SQL更新，SQL-删除，过滤器*，结果集*（查询？|？SQL查询）*）“

任何帮助将不胜感激：

在设置

之后放置连接标记部分

<class name = "cdd.model.User" table = "app_user">
    <id name = "userID" column = "user_id" type = "org.hibernate.type.PostgresUUIDType">
