二、解决步骤

1. 根据现象"一刷新就又好了"和GenericJDBCException,可以判断会话连接池有关系（应该需要优化其连接有效时间、连接数等参数）

2. 在根据“java.sql.SQLException: Connection oracle.jdbc.driver.OracleConnection@4d9119 is closed.”可以判断是使用的数据库连接已经关闭了，但是还进行了该连接的查询操作（com.iss.pms.dao.impl.UserDao.getUserMenus(UserDao.java:47)），如下所示代码段

46.      Query query = this.getHibernateSession().createQuery("from Menu ");

47       userMemuList = (List<Menu>)query.list();

3. 如上分析，session的查询对象生命周期有效的情况下，其对应的数据库连接编号4d9119被强行关闭，肯定数据库连接池参数到达上限造成的，现有配置参数如下

<bean id="dataSource"@b@        class="org.apache.commons.dbcp.BasicDataSource"  destroy-method="close">@b@         <property name="driverClassName" value="${jdbc.driverClassName}"/>@b@        <property name="url" value="${jdbc.url}"/>@b@        <property name="username" value="${jdbc.username}"/>@b@        <property name="password" value="${jdbc.password}"/>@b@        <property name="initialSize">@b@        <!-- 初始化连接数 -->@b@                <value>4</value>@b@        </property>@b@        <property name="maxIdle">@b@        <!-- 最大空闲连接 -->@b@               <value>8</value>@b@        </property>@b@        <property name="minIdle">@b@        <!-- 最小空闲连接 -->@b@               <value>6</value>@b@        </property>@b@        <property name="maxWait">@b@        <!-- 超时等待时间(毫秒) -->@b@               <value>120000</value>@b@        </property>@b@         <property name="maxActive">@b@         <!-- 最大连接数量 -->@b@               <value>10</value>@b@        </property>@b@        <property name="defaultAutoCommit">@b@                <value>true</value>@b@        </property>@b@        <property name="logAbandoned">@b@        <!-- 否在自动回收超时连接时打印连接的超时错误 -->@b@                <value>true</value>@b@        </property>@b@        <property name="removeAbandoned">@b@        <!-- 是否自动回收超时连接 -->@b@                <value>true</value>@b@        </property>@b@        <property name="removeAbandonedTimeout">@b@        <!-- 超时时间(秒) -->@b@                <value>120</value>@b@         </property>@b@          @b@        <property name="testOnReturn">@b@                <value>true</value>@b@        </property>@b@        <property name="testWhileIdle">@b@               <value>true</value>@b@        </property> @b@    </bean>

将最大连接数及超时、等待时间分别上调，具体改为为

<bean id="dataSource"@b@        class="org.apache.commons.dbcp.BasicDataSource"  destroy-method="close">@b@         <property name="driverClassName" value="${jdbc.driverClassName}"/>@b@        <property name="url" value="${jdbc.url}"/>@b@        <property name="username" value="${jdbc.username}"/>@b@        <property name="password" value="${jdbc.password}"/>@b@        <property name="initialSize">@b@        <!-- 初始化连接数 -->@b@                <value>4</value>@b@        </property>@b@        <property name="maxIdle">@b@        <!-- 最大空闲连接 -->@b@               <value>8</value>@b@        </property>@b@        <property name="minIdle">@b@        <!-- 最小空闲连接 -->@b@               <value>6</value>@b@        </property>@b@        <property name="maxWait">@b@        <!-- 超时等待时间(毫秒) -->@b@               <value>200000</value>@b@        </property>@b@         <property name="maxActive">@b@         <!-- 最大连接数量 -->@b@               <value>30</value>@b@        </property>@b@        <property name="defaultAutoCommit">@b@                <value>true</value>@b@        </property>@b@        <property name="logAbandoned">@b@        <!-- 否在自动回收超时连接时打印连接的超时错误 -->@b@                <value>true</value>@b@        </property>@b@        <property name="removeAbandoned">@b@        <!-- 是否自动回收超时连接 -->@b@                <value>true</value>@b@        </property>@b@        <property name="removeAbandonedTimeout">@b@        <!-- 超时时间(秒) -->@b@                <value>300</value>@b@         </property>@b@          @b@        <property name="testOnReturn">@b@                <value>true</value>@b@        </property>@b@        <property name="testWhileIdle">@b@               <value>true</value>@b@        </property> @b@    </bean>
