Problem description
In this project I am working on, the database is across regions and is not managed by myself. The firewall will automatically disconnect the database every once in a while.
So you need to configure the datasource of application.properties. Ps: I use mybatis to connect to the database.
Configuration and specific meaning
#初始化连接 spring.datasource.initial-size=10 #最大空闲连接 spring.datasource.max-idle=20 #最小空闲连接 spring.datasource.min-idle=5 #最大连接数量 spring.datasource.max-active=50 #是否在自动回收超时连接的时候打印连接的超时错误 spring.datasource.log-abandoned=true #是否自动回收超时连接 spring.datasource.remove-abandoned=true #超时时间(以秒数为单位) spring.datasource.remove-abandoned-timeout=180 ##<!-- 超时等待时间以毫秒为单位 6000毫秒/1000等于60秒 --> spring.datasource.max-wait=1000 spring.datasource.test-while-idle=true #检测数据库的查询语句 spring.datasource.validation-query=select 1 from dual spring.datasource.test-on-borrow=true #每隔五分钟检测空闲超过10分钟的连接 spring.datasource.min-evictable-idle-time-millis=600000 spring.datasource.time-between-eviction-runs-millis=300000
