mysql - 我不断收到“无法获得 jdbc 连接嵌套异常”

Question

我正在尝试在本地数据库中使用 CAS 服务器，但是我不断收到could not get jdbc connection nested exception错误消息。我按照以下方式设置了 deployerconfigcontext

 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName">
        <value>com.mysql.jdbc.Driver</value>
    </property>
    <property name="url">
        <value>jdbc:mysql://127.0.0.1:3306/usermanagement</value>
    </property>
    <property name="username">
        <value>root</value>
    </property>
</bean>

我得到的完整错误是

Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory <Access denied for user 'root'@'localhost'<using password:NO>>
