二、解决方法
将原application.yml配置
server:@b@ port: 8866@b@spring:@b@ application:@b@ name: mybatis@b@ #mysql@b@ datasource:@b@ url: jdbc:mysql://localhost:3306/demo2?charsetEncoding=utf-8&useSSL=false@b@ username: root@b@ password: root@b@ #mybatis-plus@b@mybatis-plus:@b@ configuration:@b@ log-impl: org.apache.ibatis.logging.stdout.StdOutImpl #开启SQL语句打印
改为 “jdbc:mysql://127.0.0.1:3306/demo2?serverTimezone=GMT%2B8&characterEncoding=UTF-8”
server:@b@ port: 8866@b@spring:@b@ application:@b@ name: mybatis@b@ #mysql@b@ datasource:@b@ url: jdbc:mysql://127.0.0.1:3306/demo2?serverTimezone=GMT%2B8&characterEncoding=UTF-8@b@ username: root@b@ password: root@b@ #mybatis-plus@b@mybatis-plus:@b@ configuration:@b@ log-impl: org.apache.ibatis.logging.stdout.StdOutImpl #开启SQL语句打印
