1.引入依赖

<dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
        <version>1.1.10</version>
    </dependency>
    
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>

2.在application.yml文件中配置相关的属性值

type: com.alibaba.druid.pool.DruidDataSource
    #监控统计拦截的filters
    filters: stat,wall,log4j
    #druid配置
    #配置初始化大小/最小/最大
    initialSize: 5
    minIdle: 5
    maxActive: 20
    #获取连接等待超时时间
    maxWait: 60000
    #间隔多久进行一次检测，检测需要关闭的空闲连接
    timeBetweenEvictionRunsMillis: 60000
    #一个连接在池中最小生存的时间
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    #打开PSCache，并指定每个连接上PSCache的大小。oracle设为true，mysql设为false。分库分表较多推荐设置为false
    poolPreparedStatements: true
    maxPoolPreparedStatementPerConnectionSize: 20
    # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
    connectionProperties:
      druid:
        stat:
          mergeSql: true
          slowSqlMillis: 5000

3.编写配置类，将自定义的的组件注入到IOC容器中

import com.alibaba.druid.pool.DruidDataSource;
    import com.alibaba.druid.support.http.StatViewServlet;
    import com.alibaba.druid.support.http.WebStatFilter;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.boot.web.servlet.FilterRegistrationBean;
    import org.springframework.boot.web.servlet.ServletRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.context.annotation.PropertySource;
    
    import javax.sql.DataSource;
    
    /**
     * @author 
     * @date 2019-09-25 16:51
     * druid参数配置
     */
    @Configuration
    @PropertySource(value = "classpath:application.yml")
    public class DruidConfiguration {
        /**
         * @author zzx
         * @date 2018-10-15 11:28
         * @todo 数据源配置
         */
        @Bean
        @ConfigurationProperties(prefix = "spring.datasource")
        public DataSource druidDataSource() {
            DruidDataSource druidDataSource = new DruidDataSource();
            return druidDataSource;
        }
    
        /**
         * druid
         * 注册一个StatViewServlet
         * @return
         */
        @Bean
        public ServletRegistrationBean druidStatViewServlet(){
            //org.springframework.boot.context.embedded.ServletRegistrationBean提供类的进行注册.
            ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
    
            //添加初始化参数：initParams
            //白名单：
            servletRegistrationBean.addInitParameter("allow","");
            //IP黑名单 (存在共同时，deny优先于allow) : 如果满足deny的话提示:Sorry, you are not permitted to view this page.
            //servletRegistrationBean.addInitParameter("deny","192.168.1.73");
            //登录查看信息的账号密码.
            servletRegistrationBean.addInitParameter("loginUsername","admin");
            servletRegistrationBean.addInitParameter("loginPassword","admin");
            //是否能够重置数据.
            servletRegistrationBean.addInitParameter("resetEnable","false");
            return servletRegistrationBean;
        }
    
        /**
         * druid过滤器
         * 注册一个：filterRegistrationBean
         * @return
         */
        @Bean
        public FilterRegistrationBean druidStatFilter(){
            FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
            //添加过滤规则.
            filterRegistrationBean.addUrlPatterns("/*");
            //添加不需要忽略的格式信息.
            filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
            return filterRegistrationBean;
        }
    }
