Question

我在jpa2（eclipseLink），spring 4.0.2，hibernate 4.3中使用以下持久性配置。不知何故，查询结果总是被缓存，即当我通过插入新行更改另一个应用程序（例如直接sql）中的数据库时，除非我重新启动服务器（这里是tomcat7），否则不会在此处返回新行。我在这里错过了什么吗？非常感谢！

我添加连接池后，现在一切正常; - ）

        <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
        <property name="hibernate.connection.provider_class" value="org.hibernate.connection.C3P0ConnectionProvider" />
