1、引入依赖

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid-spring-boot-starter</artifactId>
  <version>1.1.13</version>
</dependency>

2、YAML配置

spring:

      driverClassName: com.mysql.cj.jdbc.Driver
      type: com.alibaba.druid.pool.DruidDataSource
      druid: # #
           url: ${mysql.url}?${jdbcUrlArgs}
