Question

我收到一个奇怪的错误，我无法在eclipse中重现但出现在服务器上。

表示：

Caused by: java.sql.BatchUpdateException: Batch entry 0 
update public.user set 
    is_at='[B@136ef65', 
    user_name='elk', 
    password='33e79218965eb72c92a549dd5a330113',

where user_id='[B@19ee400' 
was aborted.  Call getNextException to see the cause.

跟随

java.lang.IllegalArgumentException: id to load is required for loading

失败是因为（hibernate？）无法将属性is_at和user_id转换为字符串。它似乎尝试使用对象上的二进制表示形式对查询进行参数化。

相关的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>

我看不出什么奇怪的，也许更多的眼睛看到更多？奇怪的是，我的IDE正在运行。有人见过类似的错误吗？

休眠：3.6.2
版本tomcat 6.0.33
java openjdk 1.6.0.18
postgresql：8.3.9

更新：

此代码的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();
