SpringBoot-整合Druid连接池

Posted 2021-02-21 碰到什么写什么

 

.yml 格式配置

  # 数据库配置
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf8&characterSetResults=utf8&useSSL=false
    username: root
    password: 123456
    # 设置连接池为Druid
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      # 初始化大小，最大，最小
      initial-size: 5
      max-active: 20
      min-idle: 5
      # 配置获取连接等待超时的时间
      max-wait: 60000
      # 配置PSCache，指定每个连接上 PSCache 的大小
      pool-prepared-statements: false
      max-pool-prepared-statement-per-connection-size: 20
      # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位毫秒
      time-between-eviction-runs-millis: 60000
      # 配置一个连接在池中最大，最小生存时间
      max-evictable-idle-time-millis: 300000
      min-evictable-idle-time-millis: 60000
      validation-query: SELECT 1 FROM
      validation-query-timeout: 60000
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
      # 配置多个英文逗号分隔
      filters: stat,log4j2,slf4j
      # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
      connection-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

 ps：如果没有防火墙建议不要开启 PS Cache
