解决方案一
查看applicationContext.xml(Spring配置文件)配置文件中的 name
值是否如下:
Druid数据源
- name=“driverClassName” 不是 “driver”
- name=“url”
- name=“username” 不是 “name"或者"user”
- name=“password”
<!-- 引入外部文件-->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 将数据源交给IOC容器管理-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
解决方案二
查看:jdbc.properties
文件是否书写正确
- 连接账户和密码是否正确
- 如果是用
mysql8.0
下面的jdbc.driver
要改成com.mysql.cj.jdbc.Driver
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.211.129:3306/spring_db?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8&useSSL=false
jdbc.username=root
jdbc.password=root
