Question

I'm trying to create a web application using Spring Boot(STS), but I got the following error while running through server(JBoss)

Description:

Failed to bind properties under '' to com.zaxxer.hikari.HikariDataSource:

Property: driverclassname
Value: org.postgresql.Driver
Origin: "driverClassName" from property source "source"
Reason: Failed to load driver class org.postgresql.Driver in either of 
HikariConfig class loader or Thread context classloader

Action:

 Update your application's configuration

Answer 1

You don't have driver on your classpath.

Add postgresql dependency under pom.xml like below.

<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<scope>runtime</scope>
</dependency>
