Answer 1

JDBC 连接那 密码或者用户名 或者地址有错误 检查下这块

Answer 2

1. dbcp连接.查看是否有导入相关的jar..
2. 连接语句是否写对.用户名,密码等的配置是否写对了..你可以在Myeclipse Hibernate视图查看连接:
3. 检查代码: 如，
<bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName"
            value="com.mysql.jdbc.Driver">
        </property>
        <property name="url"
            value="jdbc:mysql://127.0.0.1:3306/dgssen"> <!-- mysql连接 -->
        </property>
        <property name="username" value="root"></property> <!-- 用户名是否正确 -->
        <property name="password" value="123456"></property> <!-- 密码是否正确,是你连接的密码.我这里的是我mysql的连接密码 -->
    </bean>
