1.Maven加载jar包

        <!--阿里巴巴durid https://mvnrepository.com/artifact/com.alibaba/druid -->

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.9</version>
        </dependency>

2.在application.properties配置文件中写相关配置信息

server.port=8081

spring.datasource.url=jdbc:mysql://localhost:3306/thirdteam?useSSL=false&characterEncoding=UTF-8&?useUnicode=true
spring.datasource.username=root
spring.datasource.password=admin
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.filter=stat,wall,log4j
spring.datasource.tomcat.initial-size=1
spring.datasource.maxWait = 60000
spring.datasource.minIdle = 1
spring.datasource.timeBetweenEvictionRunsMillis = 60000
spring.datasource.minEvictableIdleTimeMillis = 300000
spring.datasource.validationQuery = select 'x'
spring.datasource.testWhileIdle = true
spring.datasource.testOnBorrow = false
spring.datasource.testOnReturn = false
spring.datasource.poolPreparedStatements = true
spring.datasource.maxOpenPreparedStatements = 20

3.添加Druid配置

package com.song.util.Durid;

import com.alibaba.druid.support.http.StatViewServlet;
import org.apache.catalina.filters.WebdavFixFilter;
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 javax.servlet.ServletRegistration;

@Configuration
public class DuridConfiguration {

    @Bean//声明bean实例
    public ServletRegistrationBean  stateViewServlet(){
        //创建servlet注册实体
    ServletRegistrationBean servletRegistrationBean =new ServletRegistrationBean(new StatViewServlet(),"/druid/*");
    //设置ip白名单
        servletRegistrationBean.addInitParameter("allow","127.0.0.1");
        //设置ip黑名单，如果allow与deny共同存在时，deny优于allow
        servletRegistrationBean.addInitParameter("denny","192.168.0.100");
        //设置druid登录入口，1267.0.0.1/druid/login.html
        servletRegistrationBean.addInitParameter("loginUsername","druid");
        servletRegistrationBean.addInitParameter("loginPassword","123456");
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return  servletRegistrationBean;
    }
    @Bean
    public FilterRegistrationBean statFilter(){
        //创建过滤器
        FilterRegistrationBean filterRegistrationBean =new FilterRegistrationBean(new WebdavFixFilter());
        //设置过滤路径
        filterRegistrationBean.addUrlPatterns("/*");
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,/druid/*");
        return filterRegistrationBean;
        
    }

}

4、接着登录http://localhost:8081/druid/index.html就可以监控数据库了。
