在開發項目中如果數據庫選型為mysql，很大概率下連接池會使用druid這里介紹springboot集成durid

springboot : 2.1.9druid : 1.1.10

github地址

需要引入的pom

<dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.10</version> </dependency>

需要在application.yaml中添加一些配置

spring: datasource: type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.cj.jdbc.Driver platform: mysql url: jdbc:mysql://127.0.0.1:3306/xxx?useUnicode=true&characterEncoding=utf8&autoReconnect=true&useSSL=false username: root password: 123456 initialSize: 5 minIdle: 5 maxActive: 20 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT1FROMDUAL testWhileIdle: true testOnBorrow: false testOnReturn: false filters: stat,wall,log4j logSlowSql: true

到此springboot就集成的druid的配置 可以直接使用

DruidConfiguration

import com.alibaba.druid.support.http.StatViewServlet;import com.alibaba.druid.support.http.WebStatFilter;import org.slf4j.Logger;import org.slf4j.LoggerFactory;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;/** * 數據庫鏈接池druid監控平臺的配置 * 訪問路徑 http://localhost:8080/druid/index.html * */@Configurationpublic class DruidConfiguration { private static final Logger logger = LoggerFactory.getLogger(DruidConfiguration.class); @Bean public ServletRegistrationBean druidServlet() { logger.info('init Druid Servlet Configuration '); ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), '/druid/*'); // IP白名單// servletRegistrationBean.addInitParameter('allow', '*'); // IP黑名單(共同存在時，deny優先于allow)// servletRegistrationBean.addInitParameter('deny', '192.168.1.100'); //控制臺管理用戶 servletRegistrationBean.addInitParameter('loginUsername', 'admin'); servletRegistrationBean.addInitParameter('loginPassword', 'admin'); //是否能夠重置數據 禁用HTML頁面上的“Reset All”功能 servletRegistrationBean.addInitParameter('resetEnable', 'false'); return servletRegistrationBean; } @Bean public FilterRegistrationBean filterRegistrationBean() { FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter()); filterRegistrationBean.addUrlPatterns('/*'); filterRegistrationBean.addInitParameter('exclusions', '*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*'); return filterRegistrationBean; }}測試界面

監控界面的詳細使用說明有待大家按需求進行挖掘
