在springbooot项目的pom引入druid连接池依赖

<dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>druid</artifactId>
                <version>1.1.12</version>
            </dependency>

在application.yml中配置数据库连接池信息：

spring:
      datasource:
        url: jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8
        username: root
        password: 123456
        driver-class-name: com.mysql.jdbc.Driver
        type: com.alibaba.druid.pool.DruidDataSource
        platform: mysql
        # 下面为连接池的补充设置，应用到上面所有数据源中
        # 初始化大小，最小，最大
        initialSize: 5
        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
        # 打开PSCache，并且指定每个连接上PSCache的大小
        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
        # 合并多个DruidDataSource的监控数据
        #useGlobalDataSourceStat: true

接着在项目中编写Druid的配置类

@Configuration
    public class DruidConfig {
    
        @Bean
        @ConfigurationProperties(prefix = "spring.datasource")
        public DataSource druidDataSource() {
            return new DruidDataSource();
        }
    
    
    
        @Bean
        public ServletRegistrationBean statViewServlet() {
            ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
            servletRegistrationBean.addInitParameter("loginUsername", "admin");
            servletRegistrationBean.addInitParameter("loginPassword", "admin");
            return servletRegistrationBean;
        }
    
        @Bean
        public FilterRegistrationBean statFilter() {
            FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
            filterRegistrationBean.addUrlPatterns("/*");
            filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
            return filterRegistrationBean;
        }
    
    }

启动springboot项目，[http://localhost:8080/druid/index.html][http_localhost_8080_druid_index.html]  登陆即可。
