java.sql.SQLException: ORA-01000: maximum open cursors exceeded
帖子内容有点长、大侠们耐心点看:
系统用的SSH框架、有时候前台点击跟数据库交互就会报超出最大游标数的错误。
我不知道什么问题、下面把配置跟部分代码贴出来、大侠指正。
数据源:
XML code

<Resource
                    name="jdbc/customermanage"
                    auth="Container"
                    type="javax.sql.DataSource"
                    maxActive="100"
                    maxIdle="30"
                    maxWait="10000"
                    username="......"
                    password="......" 
                    driverClassName="oracle.jdbc.OracleDriver"
                    url=".................."/>


Spring配置:
XML code

<aop:config>
        <aop:pointcut id="logger" expression="execution(* com.chinaboxun.*.*.service.*(..))" />
        <aop:aspect id="loggerAspect" ref="genericLogger">   
            <aop:around pointcut-ref="logger" method="invoke" />   
        </aop:aspect>  
    </aop:config>
<bean id="TransactionProxyFactory" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true">
        <property name="transactionManager" ref="TransactionManager"/>
        <property name="transactionAttributes">
            <props>
                <prop key="add*">PROPAGATION_REQUIRED</prop>
                <prop key="save*">PROPAGATION_REQUIRED</prop>
                <prop key="update*">PROPAGATION_REQUIRED</prop>
                <prop key="del*">PROPAGATION_REQUIRED</prop>
                <prop key="run">PROPAGATION_REQUIRED</prop>
                <prop key="send*">PROPAGATION_REQUIRED</prop>
                <prop key="doInit*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="query*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="is*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="edit*">PROPAGATION_REQUIRED</prop>
            </props>
        </property>
    </bean>


事务处理呢、是木有问题的。
在Action调用Service的方法(不处理异常信息):
Java code

Object[] objs =customerManage.selectBymanage(......);
//......


Service呢调用dao层方法(try了一下异常信息、但是dao层方法并不将异常抛出来):
Java code

numbers = hqlDao.find(sqlCount.toString(), params);
//......


dao层方法:
Java code

//类继承了HibernateDaoSupport
private Session session = null;
public List<T> find(String hql, List<T> params, int pageRows, int pageIndex){
        // TODO Auto-generated method stub
        List result = null;
        if (null !
