当 Hikari 给出连接超时时如何重新启动 spring 启动应用程序？

Question

We have spring boot application & getting below exception. Solution for that is only spring boot application restart.

Question 1: How I come to know that I am getting below exception and now need application restart?

Question 2: How to restart the spring boot application?

Exception:

Failed to obtain JDBC connection; nested exception is a java.sql.SQLTransientConnectionException:HikariPool-1

Answer 1

You can use this in your application.properties :

spring.datasource.hikari.connection-timeout=600000
spring.datasource.hikari.maximum-pool-size=500
spring.datasource.hikari.max-lifetime=1800000
spring.datasource.hikari.minimum-idle=20
spring.datasource.hikari.validation-timeout=3000
spring.datasource.hikari.idle-timeout=60000

and if you only want to restart kill the tomcat server you can use this command:

sudo kill -9 `sudo lsof -t -i:8080`

Answer 2

Bellow configuration worked for me so don't need to restart also. Thanks everyone for your help.

spring.datasource.hikari.connection-timeout = 600000

spring.datasource.hikari.maximum-pool-size = 15

spring.datasource.hikari.max-lifetime=1800000
