Spring Boot MySql Access denied for user 'root'@'localhost'

Question

I have spring boot app and deployed to a remote server. The app runs on my computer. MySQL connection URL, user name and password are the same local and remote MySQL. DB and app in same machine!!

I checked my connection info and executed about below commands.

GRANT ALL PRIVILEGES ON burrda.* TO 'root'@'localhost' IDENTIFIED BY 'password'; 
FLUSH PRIVILEGES;

My application.properties is below.

spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL57Dialect
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/burrda
spring.datasource.username=root
spring.datasource.password= password

When apps runs I'm getting java.sql.SQLException: Access denied for user 'root'@'localhost'

I'm not getting these exceptions java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES) or java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: NO)

Answer 1

I also faced the same issue.

The solution which worked for me

1. Create a new user
2. Grant this new user privileges of your database:

create user '<new_user_name>'@'localhost' identified by '<new_user_password>';
grant all privileges on <your_db_name>.* to '<new_user_name>'@'localhost' identified by '<new_user_password>';

Answer 2

The SQL command for granting the user must not contain PASSWORD keyword, it must be like:

GRANT ALL PRIVILEGES ON burrda.* TO 'root'@'localhost' IDENTIFIED BY 'password';

Answer 3

I know it's way to late.. I got this issue in a spring-boot application.

I solved this problem by using defaults, let me explain.

When I used hibernate, I use the property

<property name="connection.user">root</property>

ie connection.user

now, I tried using the same in spring-boot application.

spring.datasource.user

I get this error.

Solution is spring.datasource.username

Answer 4

It's unclear from your question, does DB runs in same machine where web application is running? If no, you need to provide IP address of the remote machine where the web application is running in the GRANT command.
