今天用hibernate做系统的时候,出现了Could not execute JDBC batch update错误,现在已经解决。
先说说我的代码:
这是角色表对应的配置文件,当我在角色管理列表的jsp页面里删除选中的角色信息,就报了上面的错误。

每创建角色,都对应着创建人的id,但是我为了测试省事,直接把数据插进表里,并且没有在表里插入创建人的userId,再看看代码:
/** */
/**
* 批量删除角色
*/
public boolean deleteRoles(String roleids) throws Exception ... {
String[] roleidArray = roleids.split(",");
for(int i=0; i<roleidArray.length; i++)...{
Trole trole = (Trole)this.getHibernateTemplate().get(Trole.class,new Integer(roleidArray[i]));
trole.setIsDel("1");
this.getHibernateTemplate().saveOrUpdate(trole);
}
return true;
}
* 批量删除角色
*/
public boolean deleteRoles(String roleids) throws Exception ... {
String[] roleidArray = roleids.split(",");
for(int i=0; i<roleidArray.length; i++)...{
Trole trole = (Trole)this.getHibernateTemplate().get(Trole.class,new Integer(roleidArray[i]));
trole.setIsDel("1");
this.getHibernateTemplate().saveOrUpdate(trole);
}
return true;
}
没有什么问题,但是却报了Could not execute JDBC batch update的错,主要是配置文件设置了关联,数据却没有关联造成的,只要数据正确就没有问题。
另外,造成这个原因的还可能是数据库的驱动jar包不支持。
还有就是csdn的dizhang的专栏提到的下面问题引起的:
1.因为Hibernate Tools(或者Eclipse本身的Database Explorer)生成*.hbn.xml工具中包含有catalog="***"(*表示数据库名称)这样的属性,将该属性删除就可以了
2.估计是你的列名里面有关键字的原因吧,命名列的时候不要单独使用date,ID...这种关键字
Hibernate查询时候的问题。
莫名其妙地报如下的错误,
org.hibernate.exception.GenericJDBCException: could not execute query
