330913157 [[ACTIVE] ExecuteThread: ‘2‘ for queue: ‘weblogic.kernel.Default (self-tuning)‘] WARN org.hibernate.util.JDBCExceptionReporter - SQL Error: 1795, SQLState: 42000
330913157 [[ACTIVE] ExecuteThread: ‘2‘ for queue: ‘weblogic.kernel.Default (self-tuning)‘] ERROR org.hibernate.util.JDBCExceptionReporter - ORA-01795: 列表中的最大表达式数为 1000

页面信息：

could not execute query; nested exception is org.hibernate.exception.SQLGrammarException: could not execute quer

原因：

在Hibernate进行Hql查询时,Hql中的in（）条件中的数目不能大于1000.导致抛出could not execute query; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query异常

解决方式：

修改in中的条件数目。
