我收到一个无法在 Eclipse 中重现但出现在服务器上的奇怪错误。
说:
Caused by: java.sql.BatchUpdateException: Batch entry 0
update public.user set
is_at='[B@136ef65',

跟随
java.lang.IllegalArgumentException: id to load is required for loading
它失败是因为(休眠?)无法将属性 is_at 和 user_id 转换为字符串。它似乎试图用对象上的某种二进制表示来参数化查询。
相关 hbm.xml 片段:
<id name="userId" type="java.lang.Long">
<column name="user_id" />
<generator class="sequence">
<param name="sequence">user_user_id_seq</param>
</generator>
</id>
<many-to-one name="checkin" class="org.server.entity.Checkin" fetch="select">
<column name="is_at" />
</many-to-one>
我看不到任何奇怪的东西,也许更多的眼睛看得更多?奇怪的是,在我的 IDE 中工作。有人见过类似的错误吗?
hibernate: 3.6.2
版本 tomcat 6.0.33
java openjdk 1.6.0.18
postgresql: 8.3.9
更新:
用于此的 Java 代码:
// queryHistory is to be persisted
// user is not null
queryHistory.setUser(user);
queryHistory.setApiKey(apiKey);
// create point
Coordinate coordinate = new Coordinate(queryHeader.getLocLon(),queryHeader.getLocLat());
GeometryFactory geometryFactory = new GeometryFactory(new PrecisionModel(),4326);
Point point = geometryFactory.createPoint(coordinate);
queryHistory.setGeom(point);
if(user!=null) {
user.setGeom(point);
user.setLastSeenAt(new Timestamp(new Date().getTime()));
hSession.update(user);
}
hSession.persist(queryHistory);
t.commit();
