java.sql.SQLFeatureNotSupportedException: Method org.postgresql.jdbc4.Jdbc4Connection.isValid(int) is not yet implemented. in Spring Boot

Question

I am developing Spring Boot Microservices example. In this example, I used config-server and licensing-service and deployed successfully on docker. When I call the REST endpoint : http://localhost:8080/v1/organizations/1/licenses, I got the below error.

To solve this error, I went through many links already, but none of the solutions worked for me yet. The refer links :

I have taken actual code reference from : https://github.com/carnellj/spmia-chapter3

1. Method org.postgresql.jdbc4.Jdbc4Connection.isValid(int) is not yet implemented
2. https://sbforge.org/jira/browse/BITMAG-508

Error:

java.sql.SQLFeatureNotSupportedException: Method org.postgresql.jdbc4.Jdbc4Connection.isValid(int) is not yet implemented.

Answer 1

Try using

<!-- https://mvnrepository.com/artifact/org.postgresql/postgresql -->
<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>42.2.5</version>
</dependency>

instead. It is the latest version from the maven repository. Tried it locally and it cleared out the error.
