springboot整合druid

添加依赖

com.alibaba
druid
1.1.6

org.springframework.boot
spring-boot-starter-web

配置druid参数application-dev.yml

数据库访问配置

主数据源，默认的

spring:
datasource:
type: com.alibaba.druid.pool.DruidDataSource
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/rest?useUnicode=true&characterEncoding=utf8&autoReconnect=true&useSSL=true
username: root
password: aA123456

下面为连接池的补充设置，应用到上面所有数据源中

初始化大小，最小，最大

initialSize: 5
minIdle: 5
maxActive: 20
# 配置获取连接等待超时的时间
maxWait: 60000
# 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
timeBetweenEvictionRunsMillis: 60000
# 配置一个连接在池中最小生存的时间，单位是毫秒
minEvictableIdleTimeMillis: 300000
validationQuery: SELECT 1 FROM DUAL
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
# 打开PSCache，并且指定每个连接上PSCache的大小
poolPreparedStatements: true
maxPoolPreparedStatementPerConnectionSize: 20
# 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,log4j
# 通过connectProperties属性来打开mergeSql功能；慢SQL记录
connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

合并多个DruidDataSource的监控数据

spring.datasource.useGlobalDataSourceStat=true

配置WebMvcConfig，继承WebMvcConfigurerAdapter

package com.binfoo.config;

import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
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 org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

/**
* 配置Druid数据源和监控界面
* 使用嵌入式的Tomcat进行注册
* @return
/
@Bean
public ServletRegistrationBean servletRegistrationBean() {
//org.springframework.boot.context.embedded.ServletRegistrationBean提供类的进行注册.
ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/");

//添加初始化参数：initParams
//白名单：
servletRegistrationBean.addInitParameter("allow", "127.0.0.1");

//IP黑名单 (存在共同时，deny优先于allow) : 如果满足deny的话提示:Sorry, you are not permitted to view this page.
servletRegistrationBean.addInitParameter("deny", "192.168.1.73");

//登录查看信息的账号密码.
servletRegistrationBean.addInitParameter("loginUsername", "root");

servletRegistrationBean.addInitParameter("loginPassword", "password");

//是否能够重置数据.
servletRegistrationBean.addInitParameter("resetEnable", "false");// 禁用HTML页面上的“Reset All”功能

return servletRegistrationBean;
}

/**
* 配置Druid数据源和监控界面
* @return
*/
@Bean
public FilterRegistrationBean druidStatFilter() {

FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());

filterRegistrationBean.setName("druidWebStatFilter");

//添加过滤规则.
filterRegistrationBean.addUrlPatterns("/*");

//添加忽略的格式信息.
filterRegistrationBean.addInitParameter("exclusions", ".js,.gif,.jpg,.png,.css,.ico,/druid/*");

return filterRegistrationBean;

}

}
