#连接池配置
# 初始化大小，最小，最大
spring.datasource.druid.initial-size=5
spring.datasource.druid.min-idle=1
spring.datasource.druid.max-active=50
# 配置获取连接等待超时的时间，单位是毫秒
spring.datasource.druid.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
spring.datasource.druid.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
spring.datasource.druid.min-evictable-idle-time-millis=300000
spring.datasource.druid.validation-query= SELECT 1 FROM DUAL
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.test-on-borrow=false
spring.datasource.druid.test-on-return=false
# 打开PSCache，并且指定每个连接上PSCache的大小
spring.datasource.druid.pool-prepared-statements=false
#spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
# 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.filters=stat,wall,log4j
# 通过connectProperties属性来打开mergeSql功能；慢SQL记录
spring.datasource.druid.connection-properties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
# 合并多个DruidDataSource的监控数据
#spring.datasource.useGlobalDataSourceStat=true

##配置config,ben的形式配置
