配置JDBC事务\配置hibernate事务

datasource：

    <bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource">
      <property name="driverClassName" value="${jdbc.driverClassName}" />
      <property name="url" value="${jdbc.url}" />
      <property name="username" value="${jdbc.username}" />
      <property name="password" value="${jdbc.password}" />
      <property name="testWhileIdle" value="true" />
      <property name="testOnBorrow" value="true" />
      <property name="testOnReturn" value="false" />
      <property name="validationQuery" value="SELECT 1" />
      <property name="validationInterval" value="30000" />
      <property name="timeBetweenEvictionRunsMillis" value="30000" />
      <property name="maxActive" value="100" />
      <property name="minIdle" value="2" />
      <property name="maxWait" value="10000" />
      <property name="initialSize" value="4" />
      <property name="removeAbandonedTimeout" value="60" />
      <property name="removeAbandoned" value="true" />
      <property name="logAbandoned" value="true" />
      <property name="minEvictableIdleTimeMillis" value="30000" />
      <property name="jmxEnabled" value="true" />
    </bean>

使用JDBC时 ： 配置JDBC（ibatis）事务：

    <!-- JDBC事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <!-- 事务模板 -->
    <bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">
        <property name="transactionManager" ref="transactionManager" />
        <property name="timeout" value="10"></property>
        <property name="isolationLevelName" value="ISOLATION_READ_COMMITTED"></property>
    </bean>
    <!-- 配置支持注解方式声明事务 -->
    <tx:annotation-driven transaction-manager="transactionManager" />

使用Hibernate时，配置hibernate事务；

可以同时将： 配置JDBC（ibatis）事务、hibernate事务交给spring管理，具体怎么配置有待研究；
