problem deploying spring boot app on heroku

Question

I have a Spring boot app, with a database. For testing I used the H2 database and everything works fine. Now I'm trying to deploy my app on Heroku. In my activity feed I get the message the the build is succesfull and that the app was deployed. When I go to the URL I get an Application Error.

I'm guessing that there is a problem with my connection to the postgresql database. In Spring I'm using the JPARepository.

this is my application.properties file, this from my H2 database, so not very usefull now:

spring.h2.console.enabled=true
spring.h2.console.path=/console

on heroku I have the following config vars:

See image: the database url was filled in, password is a copy of the database settings on heroku, spring database url jdbc:postgresql:host database credentials:5432/database name and username is also a copy of the database user name

Hi Bleau, It seems that you are trying to connect to localhost:5432 and you get a connection exception: org.postgresql.util.PSQLException. Can you share your connection configuration? — Cristian Colorado

@Cristian I'm not sure, it still looks like there is a problem with the connection to the db, this is a longer extract of my log:

this is my properties file:

spring.datasource.url=${SPRING_DATASOURCE_URL}
spring.datasource.username=${SPRING_DATASOURCE_USERNAME}
spring.datasource.password=${SPRING_DATASOURCE_PASSWORD}

spring.datasource.tomcat.default-auto-commit=true

# Hibernate specific properties
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.H2Dialect
spring.jpa.properties.hibernate.id.new_generator_mappings=false

I'm using the JPA interface:

package info.climbinggyms.main;

import org.springframework.data.jpa.repository.JpaRepository;

import java.util.UUID;

public interface PictureRepository extends JpaRepository<Picture, UUID> {
}

and these are my heroku config vars:

DATABASE_URL: postgres://sbrjqzkrjkkzmc:c23d70564aa42650ea2cd1f45321a1112096f86564a2b86766ba36adf8dffa35@ec2-54-247-85-251.eu-west-1.compute.amazonaws.com:5432/dedt2i3dl1k7sm
SPRING_DATASOURCE_DRIVER-CLASS-NAME: org.postgresql.Driver
SPRING_DATASOURCE_PASSWORD: c23d70564aa42650ea2cd1f45321a1112096f86564a2b86766ba36adf8dffa35
SPRING_DATASOURCE_TYPE: org.apache.tomcat.jdbc.pool.DataSource
SPRING_DATASOURCE_URL: jdbc:postgresql://sbrjqzkrjkkzmc:c23d70564aa42650ea2cd1f45321a1112096f86564a2b86766ba36adf8dffa35@ec2-54-247-85-251.eu-west-1.compute.amazonaws.com:5432/dedt2i3dl1k7sm
SPRING_DATASOURCE_USERNAME: sbrjqzkrjkkzmc
SPRING_JPA_DATABASE-PLATFORM: org.hibernate.dialect.PostgreSQLDialect
SPRING_JPA_HIBERNATE_DDL-AUTO: update

Please read the update on my answer, you may need to update the SPRING_DATASOURCE_URL on heroku.

As per the log file you share, you are trying to connect to localhost:5432 and you receive an Exception org.postgresql.util.PSQLException. According to your image, heroku database should have a domain name like: ec2-54-247-85-251.eu-wexxxxx.

You should use the environment variables defined by heroku, you can accchieve this by modifying the properties of your app:

application.properties

spring.datasource.driverClassName=${SPRING_DATASOURCE_DRIVER-CLASS-NAME}
spring.datasource.url=${SPRING_DATASOURCE_URL}
spring.datasource.username=${SPRING_DATASOURCE_USERNAME}
spring.datasource.password=${SPRING_DATASOURCE_PASSWORD}

Please refer to heroku documentation and reference for spring-boot.

UPDATE

It seems that postgresql driver does not support the format you have on your datasource url, you need to follow next formats:

jdbc:postgresql:<host>:<port>/<database>

Given you define spring.datasource.username and spring.datasource.password.

Or

jdbc:postgresql:<host>:<port>/<database>?user=<username>&password=<password>

Note: You may get a InvocationTargetExeption due to LOB creation as createClob(), that is hibernate attempting to setup a function postgresql does not implement, you can ignore exception.

Important: Reset your credentials so none can have access to your instance.

I added this to my apllication.properties and I still have the same problem. All the documentation above is for JDBC, I'm using JPA, does that matter? Here are my settings: SPRING_DATASOURCE_DRIVER-CLASS-NAME: org.postgresql.Driver SPRING_DATASOURCE_PASSWORD: pw copied from heroku db settings SPRING_DATASOURCE_TYPE: org.apache.tomcat.jdbc.pool.DataSource SPRING_DATASOURCE_URL: jdbc:postgresql://sbrjqzkrjkkzmc:c23d70564aa42650ea2cd1f45321a1112096f86564a2b86766ba36adf8dffa35@ec2-54-247-85-251.eu-west-1.compute.amazonaws.com:5432/dedt2i3dl1k7sm SPRING_DATASOURCE_USERNAME: sbrjqzkrjkkzmc

Now you are having troubles with connection pool, you can take a look at this tutorial baeldung.com/spring-boot-tomcat-connection-pool

It finally works, I deleted all the config vars in Heroku, all the properties in Spring and only added the username, password and url in the new format and it works. This part works, I have some other issues now with my app but I'll try to fix these myself. Thank you so much for all your help. And I won't forget to change my password
