SpringBoot EntityManagerFactory not found - spring-boot

Question

So, trying to run first sprinboot application with JPA implementation and got the following error :
Description:
Field personneDAO in com.example.demo.controller.PersonneController required a bean named 'entityManagerFactory' that could not be found.
Action:
Consider defining a bean named 'entityManagerFactory' in your configuration.
tried to add #Repositoy on my repo, and #EnableJpaRepositories to the main, but it doesn't helps...
the repository (nothing too fancy):
#Repository
public interface PersonneDAO extends JpaRepository<Personne, Integer>{
}
the main :
#SpringBootApplication
#EnableJpaRepositories(basePackages ="com.example.demo.repository")
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
gradle dependencies :
dependencies {
compile('org.springframework.boot:spring-boot-starter-web')
providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
testCompile('org.springframework.boot:spring-boot-starter-test')
compile('org.apache.tomcat.embed:tomcat-embed-jasper')
compile group: 'org.hibernate', name: 'hibernate-core', version: '5.2.16.Final'
compile group: 'org.springframework.data', name: 'spring-data-jpa', version: '2.0.6.RELEASE'
testCompile group: 'com.microsoft.sqlserver', name: 'mssql-jdbc', version: '6.5.1.jre9-preview'
}
Any ideas guys? :/
PS : forgot the application.properties
spring.mvc.view.prefix = /WEB-INF/
spring.mvc.view.suffix = .jsp
spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:sqlserver://localhost/DB_TEST
spring.datasource.username=sa
spring.datasource.password=Pa$$w0rd
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver

Answer 1

JPA will not get auto-configured without spring-boot-starter-data-jpa as a dependency. With the dependency in place, you shouldn't even need #EnableJpaRepositories.
Also, you may remove spring-data-jpa as spring-boot-starter-data-jpa already depends on that.
