问题


I'm creating a spring boot application that will save JPA entities to a postgres database hosted on Heroku (localhost first to get stuff going faster). I've been at this for days trying to figure it out, so now I'm biting the bullet and asking for help.

My application.propreties file looks like this:

spring.datasource.url=postgres://localhost:5432/mydb
spring.datasource.username=myuser
spring.datasource.password=mypass
spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.maxActive=10
spring.datasource.maxIdle=5
spring.datasource.minIdle=2
spring.datasource.initialSize=5
spring.datasource.removeAbandoned=true

I'm getting these errors:

Can anyone see what I need to do to fix this?

Thanks! Mike


回答1:


Hi Based on the stack trace the issue is with Hikari configuration. You probably need to set at least datasource.type

spring.datasource.type=com.zaxxer.hikari.HikariDataSource
# hikari specific properties
spring.datasource.hikari.maximum-pool-size=50
spring.datasource.hikari.idle-timeout=1000
spring.datasource.hikari.pool-name=blah

Additional information regarding Hikari properties




回答2:


With Spring Boot 2.0.x HikariCP is the default pooling DataSource when the spring-boot-starter-data-jpa dependency is used in your pom.xml. Hikari doesn´t know spring.datasource.url but knows spring.datasource.jdbc-url instead. So the only thing you have to change, is:

spring.datasource.jdbc-url=postgres://localhost:5432/mydb

You don´t need to tell Spring about the spring.datasource.type, because it already uses Hikari as a default. If you want to switch back to Tomcat JDBC instead of Hikari, you may have a look to this so answer.
