Springboot整合Durid-数据库连接池

一、Springboot使用Durid快速开始

1、 添加依赖

<!--druid连接池-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.17</version>
</dependency>
<!--集成mysql数据库-->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.38</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-configuration-processor</artifactId>
	<optional>true</optional>
</dependency>

2、添加配置项

(1) durid连接池配置

spring:
  # 数据库配置
  datasource:
    username: ${
    
    database.username}
    password: ${
    
    database.password}
    url: ${
    
    database.url}
    driver-class-name: ${
    
    database.dirver}
    type: com.alibaba.druid.pool.DruidDataSource
    ## 方式一：durid配置
    druid:
      initial-size: 5
      min-idle: 5
      max-active: 20
      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
      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
      min-evictable-idle-time-millis: 300000
      # 启动时验证数据库是否链接
      validation-query: SELECT 1 FROM DUAL
      # 连接池声明式预编译 
      pool-prepared-statements: 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
      max-pool-prepared-statement-per-connection-size: 20
      filters: stat,wall
      use-global-data-source-stat: true
      # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
      connect-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
      # 配置统计监控
      stat-view-servlet:
        login-username: admin
        login-password: 123456
        reset-enable: false
        url-pattern: /druid/* 
        allow: 182.168.0.1 # 添加IP白名单
        deny: 192.168.0.1 # 添加IP黑名单
      # 配置统计监控
      web-stat-filter:  # 通过：http://localhost:8888/druid/login.html进入拦截界面
        url-pattern: /*  # 添加过滤规则
        exclusions: "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*"  # 忽略过滤格式
