Springboot 连接数据库配置

本文使用druid连接池和mysql作为演示，springboot默认使用HikariCP连接池。

1、引入依赖

            mysql
            mysql-connector-java
            8.0.26
        
        
            log4j
            log4j
            1.2.12
        
        
            com.alibaba
            druid
            1.2.8
        
        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            2.1.3
        

2、配置application.yml文件

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/mybatis?serverTimeZone=UTC&useUnicode=true&characterEncoding=UTF-8&useSSL=false
    username: root
    password: zhongxiaoting
