Caused by: org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user '16348'@'localhost' (using password: YES))

原配置文件

driver=com.mysql.jdbc.Driver

url=jdbc:mysql://localhost:3306/epet?useUnicode=true&characterEncoding=utf8

username=root

password=root

解决方法：在属性前加jdbc.

将配置文件该为：

jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/epet?useUnicode=true&characterEncoding=utf8

jdbc.username=epetadmin

jdbc.password=root

spring配置文件改为

    <!--    指定引入文件地址  -->
    <context:property-placeholder location="jdbc.properties"/>
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="${jdbc.driver}"></property>
        <property name="url" value="${jdbc.url}"></property>
        <property name="username" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"/>
    </bean>
