B/S系统,偶尔出现Could not execute query的错误,重新刷新后恢复正常

各位兄弟姐妹有没有解决办法?

hbm文件是用工具生成的:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-lazy="false">
<class name="PerformanceDal.Vo.T_JCSJ_JGKZ,PerformanceDal" table="T_JCSJ_JGKZ">
<id name="C_JGID" column="C_JGID" type="String" length="32" unsaved-value="0">
<generator class="assigned" />
</id>
<property name="C_SFKH" column="C_SFKH" type="String" length="1" />
<property name="C_BMLX" column="C_BMLX" type="String" length="1" />
<property name="C_JGJC" column="C_JGJC" type="String" length="32" />
<property name="C_BMLD" column="C_BMLD" type="String" length="32" />
<property name="C_ZGYLDID" column="C_ZGYLDID" type="String" length="32" />
</class>
</hibernate-mapping>

是不是底层数据库连接有些问题？
