Help - Sql server connection from spring boot app

[JAMBALHOT_RAJA]

we have almost 20 Java spring boot applications mostly Rest APIs connecting to our sql server database. As per our security policy the db password has to be changed for every 60 days and when we do that we have to update the password in vault and restart all 20 apps and there is downtime of at least 30 min. 
 

is there any other way of connecting to database from spring boot app so that even we change the db password the app is not effected and doesn’t required restart ?

Connection pooling or read password once a day from vault instead of only when you restart application

Ne App DB password read chesetappudu fetch it from Vault everytime or with a TTL preset (there is a drawback with latency in this)

, are u storing it in cache after first time read.?
