这篇文章主要用实例解析SpringBoot如何配置Druid数据监控，内容清晰明了，对此有兴趣的小伙伴可以学习一下，相信大家阅读完之后会有帮助。
druid，一个为监控而生的数据库连接池，提供可视化界面来查看sql执行情况。
1、pom文件引入druid数据源
<!--druid数据源--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.8</version> </dependency>
2、新建一个DrruidConfig配置文件
package com.example.mybatisplus.config;
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 javax.sql.DataSource;
import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;
/**
* druid数据池配置
*/
@Configuration
public class DruidConfig {
@ConfigurationProperties(prefix = "spring.datasource")
@Bean
public DataSource druid(){
return new DruidDataSource();
}
//配置Druid的监控
//1、配置一个管理后台的Servlet
@Bean
public ServletRegistrationBean statViewServlet(){
ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
Map<String,String> initParams = new HashMap<>();
//配置登录的账号密码
initParams.put("loginUsername","admin");
initParams.put("loginPassword","123456");
// initParams.put("deny","localhost"); //拒绝谁登录
//是否能够重置数据.
// bean.addInitParameter("resetEnable","false");
bean.setInitParameters(initParams);
return bean;
}
//2、配置一个web监控的filter
@Bean
public FilterRegistrationBean webStatFilter(){
FilterRegistrationBean bean = new FilterRegistrationBean();
bean.setFilter(new WebStatFilter());
Map<String,String> initParams = new HashMap<>();
initParams.put("exclusions","*.html,*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
bean.setInitParameters(initParams);
bean.setUrlPatterns(Arrays.asList("/*"));
return bean;
}
}3、yml文件配置
spring: datasource: schema: - classpath:schema.sql initialization-mode: ALWAYS username: root password: root url: jdbc:mysql://localhost:3306/jdbc?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&useSSL=false driver-class-name: com.mysql.cj.jdbc.Driver # type: com.alibaba.druid.pool.DruidDataSource initialSize: 5 minIdle: 5 maxActive: 20 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true # 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 maxPoolPreparedStatementPerConnectionSize: 20 useGlobalDataSourceStat: true connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
