spring boot配置druid数据源和监控配置

直接上代码：

一.pom.xml中添加依赖

 <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.配置数据源与监控

第一种方法通过properties配置

 #配置数据源

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
 spring.datasource.druid.initial-size=5
 spring.datasource.druid.min-idle=5
 spring.datasource.druid.max-active=20
 # 配置获取连接等待超时的时间
 spring.datasource.druid.max-wait=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
 spring.datasource.druid.time-between-eviction-runs-millis=60000
 # 配置一个连接在池中最小生存的时间，单位是毫秒
 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
 # 打开PSCache，并且指定每个连接上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
 #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
 # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
 #spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
 #spring.datasource.druid.connect-properties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
 # 合并多个DruidDataSource的监控数据
 #spring.datasource.useGlobalDataSourceStat=true

 # WebStatFilter配置，说明请参考Druid Wiki，配置_配置WebStatFilter
 #是否开启web-jdbc监控 默认是false
 spring.datasource.druid.web-stat.enabled=true
 #是否开启session统计 默认false
 spring.datasource.druid.web-stat.session-stat-enable=true
 #设置session统计的最大值 默认是1000
 spring.datasource.druid.web-stat.session-stat-max-count=1000
 #是否开启单个监控url调用的sql列表 默认开启
 spring.datasource.druid.web-stat.profile-enable=true
 #过滤器url的映射规则
 spring.datasource.druid.web-stat.url-patterns=/*
 #过滤器url的排除规则
 spring.datasource.druid.web-stat.exclusions=*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*

 # StatViewServlet配置，说明请参考Druid Wiki，配置_StatViewServlet配置
 #是否开启druid的数据统计界面 默认false
 spring.datasource.druid.stat-view-servlet.enabled= true
 #servlet映射规则，默认访问http:/**xxx/druid/
 spring.datasource.druid.stat-view-servlet.url-mappings=/druid/*
 #是否允许清空统计数据 默认false
 spring.datasource.druid.stat-view-servlet.reset-enable= false
 #设置登录名
 spring.datasource.druid.stat-view-servlet.login-username= admin
 #设置密码
 spring.datasource.druid.stat-view-servlet.login-password= admin
 #设置白名单
 spring.datasource.druid.stat-view-servlet.allow= 127.0.0.1
 #访问黑名单
 #spring.datasource.druid.stat-view-servlet.deny= 192.168.32.139 

第二种方法通过java配置类设置：

DruidConfiguration该类与主程序xxApplication同级

 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;
     }
 }
