SpringBoot 配置阿里 Druid 监控管理

前言

之前看见过Druid的界面,让我们直观感受 sql,调用的方法，还有访问 uri 等各方面的情况。但是不知道是怎么弄出来的,感觉就是高大上,最近正好学到了一招两式,然后在这里分享一下基于SpringBoot怎么配置Druid 监控管理

配置步骤

1. 在pom文件中导入druid依赖

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.12</version>
        </dependency>

2. 在resources文件下创建一个application.yml文件用于配置数据库连接

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/jdbc?serverTimezone=GMT%2B8
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource

    initialSize: 8
    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,logback
    maxPoolPreparedStatementPerConnectionSize: 25
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

3. 配置druid的后台管理servlet 和 配置druid 的filter(拦截器)

package com.mengxuegu.springboot.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.servlet.Filter;
import javax.sql.DataSource;
import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;

@Configuration
public class DruidConfig {


    @ConfigurationProperties(prefix="spring.datasource")
    @Bean
    public DataSource druid(){
        return new DruidDataSource();
    }


    //配置一个druid的后台管理servlet
    @Bean
    public ServletRegistrationBean statViewServlet(){
        //请求地址
        ServletRegistrationBean<StatViewServlet> bean = new ServletRegistrationBean<>(new StatViewServlet(), "/druid/*");

        Map<String,String> initParam = new HashMap<>();

        initParam.put(StatViewServlet.PARAM_NAME_USERNAME,"root");
        initParam.put(StatViewServlet.PARAM_NAME_PASSWORD,"123456");

        //所有IP都可以访问
        initParam.put(StatViewServlet.PARAM_NAME_ALLOW,"");

        //禁止那个IP不能访问
        initParam.put(StatViewServlet.PARAM_NAME_DENY,"192.168.10.1");

        bean.setInitParameters(initParam);
        return bean;
    }


    //配置一个druid的filter
    @Bean
    public FilterRegistrationBean webStatFilter(){
        FilterRegistrationBean<Filter> bean = new FilterRegistrationBean<>();
        bean.setFilter(new WebStatFilter());

        //设置哪些不拦截
        Map<String,String> initParmas = new HashMap<>();
        initParmas.put(WebStatFilter.PARAM_NAME_EXCLUSIONS,"*.js,*.css,/druid/*");
        bean.setInitParameters(initParmas);

        //设置拦截请求
        bean.setUrlPatterns(Arrays.asList("/*"));
        return bean;
    }
}
