這篇文章主要介紹了SpringBoot配置Druid數(shù)據(jù)監(jiān)控代碼實(shí)例,文中通過示例代碼介紹的非常詳細(xì)，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,需要的朋友可以參考下

druid，一個(gè)為監(jiān)控而生的數(shù)據(jù)庫連接池，提供可視化界面來查看sql執(zhí)行情況。

1、pom文件引入druid數(shù)據(jù)源

<!--druid數(shù)據(jù)源-->
  <dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>druid</artifactId>
   <version>1.1.8</version>
 </dependency>

2、新建一個(gè)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數(shù)據(jù)池配置
 */
@Configuration
public class DruidConfig {

  @ConfigurationProperties(prefix = "spring.datasource")
  @Bean
  public DataSource druid(){
    return new DruidDataSource();
  }
  //配置Druid的監(jiān)控
  //1、配置一個(gè)管理后臺的Servlet
  @Bean
  public ServletRegistrationBean statViewServlet(){
    ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
    Map<String,String> initParams = new HashMap<>();
    //配置登錄的賬號密碼
    initParams.put("loginUsername","admin");
    initParams.put("loginPassword","123456");
//    initParams.put("deny","localhost"); //拒絕誰登錄
    //是否能夠重置數(shù)據(jù).
//    bean.addInitParameter("resetEnable","false");
    bean.setInitParameters(initParams);
    return bean;
  }

  //2、配置一個(gè)web監(jiān)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
  #  配置監(jiān)控統(tǒng)計(jì)攔截的filters，去掉后監(jiān)控界面sql無法統(tǒng)計(jì)，'wall'用于防火墻
  filters: stat,wall
  maxPoolPreparedStatementPerConnectionSize: 20
  useGlobalDataSourceStat: true
  connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
