SpringBoot集成Druid配置(yml版本)

maven 配置

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.8</version>
        </dependency>

        <dependency>

            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.15</version>
        </dependency>

application.yml 配置

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    # 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
    initial-size: 5
    min-idle: 5
    max-active: 20
    # 配置获取连接等待超时的时间
    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
    validation-query: SELECT 1 FROM DUAL
    test-while-idle: true
    test-on-borrow: false
    test-on-return: false
    # 打开PSCache，并且指定每个连接上PSCache的大小
    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
