org.postgresql.util.PSQLException: FATAL: password authentication failed for user springboot maven project

Question

I am learning spring-boot. I have created a database called student which i want to acces using spring - boot. But when I run the project, I can this error, yet I don't have any password configured on any of my roles in the postgresql. I have tried googling, but I have failed to get it right.

This is the error I get when start running the project. I need help communicate.

My application.properties is as below

spring.datasource.url=jdbc:postgresql://localhost:5432/student
spring.datasource.username=enock
spring.datasource.password=root
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

And the postgres dependence in the pom.xml is as below

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

Answer 1

I was having the exact same issue. What I did was create a new user and granted all privileges. open cmd and type: psql -U postgres Make sure to have postgress added to the path. Then create an user with: create user user_name with encrypted password 'password'; and lastly: grant all privileges on database db_name to 'username'; This is what I have on the application.properties:

spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/db_name
spring.datasource.username=username
spring.datasource.password=password
spring.jpa.database- 
platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=update
spring.sql.init.mode=always   
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation = 
true

and in the pom.xml I added:

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
   <groupId>org.postgresql</groupId>
   <artifactId>postgresql</artifactId>
   <version>${postgresql.version}</version>
</dependency>
