hibernatete的配置问题

大神们 最近遇到一个问题 就是我用Junit做单元测试的时候 报错了：

求解 到底是哪儿出了问题  求解MySQL单元测试

  1.   

    不一定是配置出问题，你是不是操作了List之类的，看看其他代码！
      

  2.   

      <!-- 
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password">sa</property>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/guojiadianli</property>
    <property name="hibernate.connection.autocommit">true</property>
     -->
    你怎么把这个给注释了
      

  3.   

    2L正解，你把数据库的用户名密码都给注释掉了，所以才报The user must supply a JDBC connection
