Spring boot with error connecting to mysql

I created a test project by Spring Tool Suite to create a REST server that will connect to a local mysql database, when I start the app in error when trying to connect to mysql: java.sql .SQLException: Access denied for user '' @ 'localhost' (using password: NO)

I find it strange that it did not try with the root user I set up in the project.

The application.properties looks like this:

spring.jpa.show-sql=true
spring.jpa.database=mysql

spring.datasource.url=jdbc:mysql://localhost/users
spring.datasource.data-username=root
spring.datasource.data-password=12345
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

And the pom.xml looks like this:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
</properties>

        </plugin>
    </plugins>
</build>

In the database I ran the following command:

GRANT ALL ON *.* TO 'root'@'%' IDENTIFIED BY '12345';

After running I stopped and started mysql.

I understand this command to access root in all tables and from anywhere.

I find it strange that in the error '' @ localhost '' appears instead of 'root' @ 'localhost', it does not seem to get the configuration to access the database.

It will be config. of the connection that is wrong, the pom.xml or the bank?
