解决方案:
1.url:&serverTimezone=GMT加上这句话
2.加入这两行
<!--3.配置数据源--> <bean class="com.alibaba.druid.pool.DruidDataSource" id="dataSource"> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> <property name="driverClassName" value="${jdbc.driver}"/> <property name="maxActive" value="10"/> <property name="minIdle" value="5"/> </bean>
细粒度配置可参考如下的URL 配置
db mysql
spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://localhost:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&serverTimezone=Asia/Shanghai
db.user=root
db.password=1234
