Answer 2

能看一下你的com.ex.dao.impl.EmployeeDaoImpl，我是初学者，不是太会。

Answer 3

 <property name="url"
            value="jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=utf8">
        </property>
你的url连接是这个，数据库是哪个啊

Answer 4

找不到main方法，那就在main里面看看呗

Answer 5

数据库是 test 啊
这关数据库什么事啊，我的配置文件能够自动生成说明数据库连接的上啊
