springboot+druid(使用druid-spring-boot-starter配置)
参考:
https://github.com/alibaba/druid/tree/master/druid-spring-boot-starter
1.基础配置:
添加依赖:

#Druid Spring Boot Starter 配置属性的名称完全遵照 Druid，你可以通过 Spring Boot 配置文件来配置Druid数据库连接池和监控，如果没有配置则使用默认值。
#JDBC 配置
#spring.datasource.druid.url= jdbc:mysql://localhost:3306/shiro?useUnicode=true&characterEncoding=utf-8&useSSL=false
#spring.datasource.druid.username= root
#spring.datasource.druid.password= 123456
#spring.datasource.druid.driver-class-name= com.mysql.jdbc.Driver
######################等同以上配置##########################
spring.datasource.url= jdbc:mysql://localhost:3306/shiro?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username= root
spring.datasource.password= 123456
spring.datasource.driver-class-name= com.mysql.jdbc.Driver
到这里就配置完了,没错配置完了,就是这么骚,接下来运行项目检查下:
控制台出现以上信息,说明已经整合成功,接下来删除druid依赖重新运行项目,可以看到以下信息:
这时项目已经使用了springboot默认的数据库连接池,为什么添加依赖就能改变数据库连接池呢,我们来看看源码:
我们进入红框中DataSourceProperties,会发现以下信息:
通过上边的图可以发现druid-spring-boot-starter已经默认配置好了这些属性(spring.dataSource==spring.datasource.druid),你只需添加依赖即可,一切操作和以前一样处理
2.监控配置:
#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.filters= stat,wall
#######监控配置
# WebStatFilter配置，说明请参考Druid Wiki，配置_配置WebStatFilter
spring.datasource.druid.web-stat-filter.enabled=true
spring.datasource.druid.web-stat-filter.url-pattern=/*
spring.datasource.druid.web-stat-filter.exclusions=/druid/*,*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico

spring.datasource.druid.web-stat-filter.principal-session-name=session_name
spring.datasource.druid.web-stat-filter.principal-cookie-name=cookie_name
spring.datasource.druid.web-stat-filter.profile-enable=
# StatViewServlet配置，说明请参考Druid Wiki，配置_StatViewServlet配置默认false
spring.datasource.druid.stat-view-servlet.enabled=true
# 配置DruidStatViewServlet
spring.datasource.druid.stat-view-servlet.url-pattern=/druid/*
# 禁用HTML页面上的“Reset All”功能
spring.datasource.druid.stat-view-servlet.reset-enable=false
spring.datasource.druid.stat-view-servlet.login-username=admin #监控页面登录的用户名
spring.datasource.druid.stat-view-servlet.login-password=123456 #监控页面登录的密码
#IP白名单(没有配置或者为空，则允许所有访问)
spring.datasource.druid.stat-view-servlet.allow=127.0.0.1,192.168.0.119
#IP黑名单 (存在共同时，deny优先于allow)
spring.datasource.druid.stat-view-servlet.deny=
#Spring监控配置，说明请参考Druid Github Wiki，配置_Druid和Spring关联监控配置
spring.datasource.druid.aop-patterns= com.lcf.service.*
登录监控页面:
http://localhost:8080/druid/
账号:admin 密码123456(properties文件中你自己设置的)

当然如果你不喜欢阿里的监控页面,你也可以自己自定义,一下是部分监控api,更多api请看DruidStatService源码

#启用WebStatFilter，默认为false

到这里整合就完了,有什么不对请多多指导…
