错误描述
这里我使用 mybatis plus 进行批量修改时发生报错：
org.springframework.dao.TransientDataAccessResourceException:
### Error querying database. Cause: java.sql.SQLException: No operations allowed after statement closed.
### The error may exist in com/test/TestMapper.java (best guess)
### The error may involve com.test.mapper.TestMapper.selectById
### The error occurred while executing a query
### Cause: java.sql.SQLException: No operations allowed after statement closed.
; No operations allowed after statement closed.; nested exception is java.sql.SQLException: No operations allowed after statement closed.

报错显示正在执行但是连接被关闭了。
解决方案
我这里使用的数据库连接池是 druid，修改连接超时时间配置即可：
spring:
druid:
time-between-eviction-runs-millis: 60000
min-evictable-idle-time-millis: 300000
