Spring Boot didn't connect to my database-CodePudding

I connected my Postgres database with Spring Boot but something when wrong. I didn't show any error but it didn't go into the database. *I have replace my Postgres URL with $URl and $password for security issue.

spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.hikari.connectionTimeout=20000
spring.datasource.hikari.maximumPoolSize=5
spring.datasource.url=jdbc:postgresql://$URL:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=$password
spring.jpa.hibernate.ddl-auto=create

and the result was only these

2021-12-08 17:31:03.430  INFO 4216 --- [           main] com.example.demo.DemoApplication         : Starting DemoApplication using Java 17.0.1 on DESKTOP with PID 4006 (C:\Users\Thanh Lu\Desktop\demo\target\classes started by Thanh Lu in C:\Users\Any\Desktop\demo)

Any advice would be appreciate.

Thanks in advance

CodePudding user response：

I can't find JPA/Hibernate dependency in your Maven pom.xml. Try to add the following dependency there:

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

CodePudding user response：

I think you have not used any object or config relate to database. Simple, you can try create entity then add following 2 configuration in file application.properties

logging.level.com.zaxxer.hikari.HikariConfig=DEBUG
logging.level.com.zaxxer.hikari=TRACE

And in your Maven pom.xml add dependency

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

Then start project again you can see result as image below
