Spring Boot - Error creating bean with name 'dataSource' defined in class path resource

Looks like the initial problem is with the auto-config.

If you don't need the datasource, simply remove it from the auto-config process:

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

From the looks of things you haven't passed enough data to Spring Boot to configure the datasource

Create/In your existing application.properties add the following

spring.datasource.driverClassName=
spring.datasource.url=
spring.datasource.username=
spring.datasource.password=

making sure you append a value for each of properties.

Maybe you forgot the MySQL JDBC driver.

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.34</version>
</dependency>
