Question

I'm trying to connect to a database using Java Spring

properties file:

# suppress inspection "UnusedProperty" for whole file

spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.properties.hibernate.format_sql=true

pom.xml:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

org.postgresql.util.PSQLException: FATAL: database "student" does not exist
...

my postgresql:

Although I have a database named student, it says the database does not exist. Despite a lot of research, I could not solve this problem.

Note: I did not write any code, I just wrote student class, student service and student controller and tried to connect to the database with properties and run spring boot application.

Try to create new database on pgAdmin 4 manually. Right click on PostgreSQL under Server and Create -> Database -> write your database name. This may solve your problem.
