一. 相关依赖
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.21</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
二. 在application.yml中配置相关属性
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/mybatis?characterEncoding=UTF-8&useSSL=true&serverTimezone=UTC
    username: root
    password: 123456
    platform: mysql
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      # 初始化大小,最小,最大
      initialSize: 1
      minIdle: 3
      maxActive: 20
      # 配置获取连接等待超时的时间
      maxWait: 60000
      # 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒
      timeBetweenEvictionRunsMillis: 60000
      # 配置一个连接在池中最小生存的时间,单位是毫秒
      minEvictableIdleTimeMillis: 30000
      validationQuery: select 'x'
      testWhileIdle: true
      testOnBorrow: false
      testOnReturn: false
      # 是否缓存preparedStatement,打开PSCache,并且指定每个连接上PSCache的大小。官方建议MySQL下建议关闭,如果用SQL防火墙 建议打开
      poolPreparedStatements: true
      maxPoolPreparedStatementPerConnectionSize: 20
      # 配置监控统计拦截的filters,去掉后监控界面sql无法统计,'wall'用于防火墙
      filters: stat,wall,slf4j
      # 通过connectProperties属性来打开mergeSql功能;慢SQL记录
      connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
三. 进行测试
@SpringBootTest
class DemoApplicationTests {

    @Autowired
    DataSource dataSource;

    @Test
    void contextLoads() {
        System.out.println(dataSource.getClass());
    }

}
