Spring Boot 整合 Druid 数据源，虽然不会用先整上再说

# 指定数据源类型
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

# Druid 数据源设置

# 初始化时建立数据库连接的个数
spring.datasource.initialSize=10
# 最小连接池数量
spring.datasource.minIdle=5
# 最大连接池数量
spring.datasource.maxActive=30
# 配置获取连接等待超时的时间
spring.datasource.maxWait=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.timeBetweenEvictionRunsMillis=60000
# 配置一个连接在池中最小生存的时间，单位是毫秒
spring.datasource.minEvictableIdleTimeMillis=300000
# 用来检测连接是否有效的SQL语句
spring.datasource.validationQuery=SELECT 1
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
