Spring4+Struts2+Hibernate5报错：Access denied for user 'root'@'localhost' (using password: YES)

输入用户名、密码后报错，原因为：

配置文件applicationContext.xml中

<bean id="datasource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="{jdbc.password}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="driverClassName" value="${jdbc.driver}"></property>
</bean>

value忘记输入$符号！

具体报错信息如下：
