我的原因：

<context:property-placeholder location="classpath:mysql_jdbc.properties" />在找了半天后，看得到了spring的配置文件中的这个引入的数据库的属性文件，突然想到了以前看视频时，老师提到过这种引入方式有的时候会识别不出来，导致连不上数据库。

然后改成如下方式：

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:mysql_jdbc.properties"/>

</bean>

果然，是这个问题，问题解决。
