How can I connect to MySQL database

I´m tryng to connect to MySQL Database with SpringBoot, but I got this error below:

Application failed to start with classpath: [file:/C:/Dev/Repositorios/jira-quality/target/classes/, file:/C:/Users/jboscod/.m2/repository/mysql/mysql-connector-java/8.0.21/mysql-connector-java-8.0.21.jar, file:/C:/Users/jboscod/.m2/repository/org/springframework/boot/spring-boot-starter-data-jpa/2.1.9.RELEASE/spring-boot-starter-data-jpa-2.1.9.RELEASE.jar

Failed to load property source from location 'classpath:/application-desenv.yml'

My pom is this way:

And my application.properties is below:

spring.jpa.hibernate.ddl-auto = none

spring.datasource.url = jdbc:mysql://localhost:3306/jiraquality

spring.datasource.username = root

spring.datasource.password = admin

spring.datasource.driver-class-name = com.mysql.jdbc.Driver

I don´t know if the problem is in my pom or my application file.

I noticed that Failed to load property source from location 'classpath:/application-desenv.yml'

Have you try to change your application.properties to application-desenv.yml?

If you don't add Spring Data JPA on you pom file add this:

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


  
	<dependency>
       <groupId>mysql</groupId>
       <artifactId>mysql-connector-java</artifactId>
       <scope>runtime</scope>
	</dependency>

Clean your project and take Maven update.
It will be working successfully.
