spring boot配置druid數據源和監控配置

直接上代碼：

一.pom.xml中添加依賴

<dependency>
            <groupId>com.github.drtrang</groupId>
            <artifactId>druid-spring-boot2-starter</artifactId>
            <version>1.1.9</version>
        </dependency>

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.0.31</version>
        </dependency>

二.配置數據源與監控

第一種方法通過properties配置

 #配置數據源

spring.datasource.url=jdbc:mysql://106.14.xx.xx:3306/test
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.druid.username=123456
spring.datasource.druid.password=123456

 1 # 下面為連接池的補充設置，應用到上面所有數據源中
# 初始化大小，最小，最大
spring.datasource.druid.initial-size=5
spring.datasource.druid.min-idle=5
spring.datasource.druid.max-active=20
# 配置獲取連接等待超時的時間
spring.datasource.druid.max-wait=60000
# 配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒
spring.datasource.druid.time-between-eviction-runs-millis=60000
# 配置一個連接在池中最小生存的時間，單位是毫秒
spring.datasource.druid.min-evictable-idle-time-millis=300000
spring.datasource.druid.validation-query=SELECT 1 FROM DUAL
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.test-on-borrow=false
spring.datasource.druid.test-on-return=false
# 打開PSCache，並且指定每個連接上PSCache的大小
spring.datasource.druid.pool-prepared-statements=true
spring.datasource.druid.max-pool-prepared-statement-per-connection-size=20
# 配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用於防火牆
#spring.datasource.druid.filter-class-names=com.alibaba.druid.filter.stat.StatFilter
#spring.datasource.druid.filter-class-names=com.alibaba.druid.wall.WallFilter
#spring.datasource.druid.filter-class-names=com.alibaba.druid.filter.logging.Log4jFilter,com.alibaba.druid.filter.stat.StatFilter,com.alibaba.druid.wall.WallFilter
# 通過connectProperties屬性來打開mergeSql功能；慢SQL記錄
#spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
#spring.datasource.druid.connect-properties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
# 合並多個DruidDataSource的監控數據
#spring.datasource.useGlobalDataSourceStat=true

# WebStatFilter配置，說明請參考Druid Wiki，配置_配置WebStatFilter
#是否開啟web-jdbc監控 默認是false
spring.datasource.druid.web-stat.enabled=true
#是否開啟session統計 默認false
spring.datasource.druid.web-stat.session-stat-enable=true
#設置session統計的最大值 默認是1000
spring.datasource.druid.web-stat.session-stat-max-count=1000
#是否開啟單個監控url調用的sql列表 默認開啟
spring.datasource.druid.web-stat.profile-enable=true
#過濾器url的映射規則
spring.datasource.druid.web-stat.url-patterns=/*
#過濾器url的排除規則
spring.datasource.druid.web-stat.exclusions=*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*
        
# StatViewServlet配置，說明請參考Druid Wiki，配置_StatViewServlet配置
#是否開啟druid的數據統計界面 默認false
spring.datasource.druid.stat-view-servlet.enabled= true
#servlet映射規則，默認訪問http:/**xxx/druid/
spring.datasource.druid.stat-view-servlet.url-mappings=/druid/*
#是否允許清空統計數據 默認false
spring.datasource.druid.stat-view-servlet.reset-enable= false
#設置登錄名
spring.datasource.druid.stat-view-servlet.login-username= admin
#設置密碼
spring.datasource.druid.stat-view-servlet.login-password= admin
#設置白名單
spring.datasource.druid.stat-view-servlet.allow= 127.0.0.1
#訪問黑名單
#spring.datasource.druid.stat-view-servlet.deny= 192.168.32.139 

第二種方法通過java配置類設置：

DruidConfiguration該類與主程序xxApplication同級

package com.ieou.capsule;

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;

@Configuration
public class DruidConfiguration {

    @Bean
    public ServletRegistrationBean statViewServlet(){

        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");

        servletRegistrationBean.addInitParameter("loginUsername","admin");
        servletRegistrationBean.addInitParameter("loginPassword","admin");
        servletRegistrationBean.addInitParameter("resetEnable","false");
        return servletRegistrationBean;
    }

    @Bean
    public FilterRegistrationBean statFilter(){

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


        filterRegistrationBean.addUrlPatterns("/*");
        filterRegistrationBean.addInitParameter("exclusions","*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*");

        return filterRegistrationBean;
    }
}
