#StartSETUP

Greetings. I admit I'm starting to learn what I can learn. And now I'm trying to learn About JPA. After I generate with JPA, SpringBoot Devtool, and also Posters SQL dependency, I want to connect to my database. But, for 3 days I've stick with this same error:

Failed to load driver class org.postgresql.Driver in either of HikariConfig class loader or Thread context classloader

Failed to load driver class org.postgresql.Driver in either of HikariConfig class loader or Thread context classloader

What I find that the problem is only from the application.properties, but I had research that the config only this:

spring.application.name=jpa
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=12345678

spring.application.name=jpa
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=12345678

Any help please

This is what works for me: spring: datasource: url: jdbc:postgresql://localhost:5332/customer # This is the URL for the PostgreSQL Server running in docker using the 5332 mapping # Note 1: We can switch the port number to 5432 and connect to the PostgreSQL Server # running in localhost. But we will stick with the PostgreSQL running in docker for now. # "customer" is the name of the database that we are going to be creating username: postgres # username we created for PostgreSQL Server running in Docker password: password # password we created for PostgreSQL Server running in docker jpa: hibernate: ddl-auto: create-drop properties: hibernate: dialect: org.hibernate.dialect.PostgreSQLDialect format_sql: true show-sql: true main: web-application-type: servlet Below is the pox.xml file <dependencies> <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency>
