Spring Boot Application gets stuck on "Hikari-Pool-1 - Starting..." - spring

Question

I'm trying to run Spring Boot application connected to PostgreSQL database. However, when it comes to Hikari connection pool initializing, it just gets stuck and nothing goes on. HikariPool-1 - Starting... appears in logs and then nothing happens.
Logs:

My apllication.properties:
spring.datasource.url=jdbc:postgresql://127.0.0.1:55491/TodoAppDatabase
spring.datasource.username=admin
spring.datasource.password=root
spring.datasource.hikari.connection-timeout=10000
spring.datasource.hikari.driver-class-name=org.postgresql.Driver
spring.datasource.hikari.maximum-pool-size=100
spring.data.jpa.repositories.enabled=true
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQL94Dialect
spring.jpa.properties.hibernate.cache.use_query_cache=true
spring.jpa.properties.hibernate.connection.provider_class=com.zaxxer.hikari.hibernate.HikariConnectionProvider
How can I overcome this issue?

Answer 1

Normal postgresql port is 5432, so I assume you also configured it to 55491.
Double check this via your postgresql client using psql -h 127.0.0.1 -p 55491 -d TodoAppDatabase -U admin
At last you can put the HikariCP into DEBUG mode, so you can see what parameters its using.
If your properties file is really apllication.properties than this may also an issue because spring boot only picks up application.properties automatically.

Answer 2

Making below change in application.properties should work fine:
spring.datasource.url=jdbc:postgresql://localhost:5432/<dbName>
Also make sure, you have Fixed Port Number box unchecked, in the pgAdmin configuration BOX, refer the screenshot

Answer 3

In my case spring.datasource.hikari.initializationFailTimeout was set to a really high value, 3600000 (1 hour). This, in it self, was not a malconfiguration but it hid the real problem as the app was hanging on startup.
Once that value was adjusted, I got a much more understandable stack trace which led me to the conclusion that in this case I couldn't use the default MariaDB driver configuration that I probably got through a jHipster.
A very wierd problem that I so far only has seen with MySQL8 and Ubuntu 20 on AWS EC2. Locally I run Ubuntu and MySQL8 via Docker without issues.

Answer 4

It might not be able to connect to DB.
try restarting your DB instance and make sure it is accessible.

Answer 5

try passing this parameter when you run your jar file:
-Djava.security.egd=file:/dev/../dev/urandom

Answer 6

In my case it was a problem with a network connectivity. Make sure you can access your any configured servers if you got into this issue.
telnet host 5432 will let you connect to see if a route exists to the DB server.

Answer 7

in my case (windows 10), it took three steps:
stop the postgresql service running
open command prompt as administrator and kill any service on port 5432
restart the postgresql service from services window.
and you're good.

Answer 8

I had the same problem and solved this by removing the AUTO_SERVER=true line in the application.properties file, so after removing that the application runs as usual.
Remove the AUTO_SERVER=true in #spring.datasource.url=jdbc:... AUTO_SERVER=true
Whit this you loose the functionality to access the database from different sources like from the terminal, meaning you can't access the database from your terminal while your app is running (ie using the database)
But if you need AUTO_SERVER=true then please restart your pc, and with it the database will restart which might solve your problem (this is not a joke).

Answer 9

There could be several reasons why hikaripool-1 is taking a long time to start. One possibility is that there may be high traffic on the network or server, causing delays in processing requests.
Another possibility is that there may be technical issues with the software or hardware, which can also cause delays. It is recommended to check the logs and error messages for any clues about what might be causing the delay and to contact technical support for assistance if necessary.
