HikariCP Postgresql Driver Claims to not accept JDBC URL

问题

I've pushed my application to cloudfoundry. However every time I connect to my postgresql/elephant sql I received this error

 Driver org.postgresql.Driver claims to not accept JDBC URL jdbc:postgres://cwkqmdql:SsVqwdLxQObgaJAYu68O-8gTY1VmS9LX@pellefant.db.elephantsql.com:5432/cwkqmdql/

Is there anything I've missed?

回答1:

There are a few issues with that URL and a latest PSQL driver may complain.

1. jdbc:postgres: should be replaced with jdbc:postgresql:
2. Do not use jdbc:postgresql://<username>:<passwor>..., user parameters instead: jdbc:postgresql://<host>:<port>/<dbname>?user=<username>&password=<password>
3. In some cases you have to force SSL connection by adding sslmode=require parameter

So your URL should be:

jdbc:postgresql://@pellefant.db.elephantsql.com:5432/cwkqmdql?user=cwkqmdql&password=SsVqwdLxQObgaJAYu68O-8gTY1VmS9LX

or

jdbc:postgresql://@pellefant.db.elephantsql.com:5432/cwkqmdql?user=cwkqmdql&password=SsVqwdLxQObgaJAYu68O-8gTY1VmS9LX&sslmode=require

I hope that will help.

回答2:

In my case it was defining the property in double quotes in the java.properties file

by changing

jdbcUrl="url"

to

jdbcUrl=url

it works again
