这里我重点讲一下如何使用mybatisplus与druid连接池进行整合，关于springboot整合mybatisplus可参考

要引入Druid数据库连接池，其实只需要在application.yml中配置相关的druid的数据即可

server:  port: 8081spring:  datasource:    driver-class-name: com.mysql.jdbc.Driver    username: root    password: Sakura36!    url: jdbc:mysql://localhost:3306/probe?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai&llowMultiQueries=true    type: com.alibaba.druid.pool.DruidDataSource    druid:      initial-size: 5      min-idle: 5      max-active: 20      max-wait: 6000      time-between-eviction-runs-millis: 60000      min-evictable-idle-time-millis: 30000      test-on-borrow: false      test-on-return: false      pool-prepared-statements: true      max-pool-prepared-statement-per-connection-size: 20mybatis-plus:  configuration:    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl    map-underscore-to-camel-case: true # 开启驼峰命名转换:Table{   create_time} -> Entity{   createTime}    use-generated-keys: true #使用jdbc的getGeneratedKeys获取数据库自增主键值

配置上述即可
