java - Spring Boot JPA - No qualifying bean of type -

i'm learning spring , things going running issue cannot find qualified bean. hitting wall, in new app i'm getting this.

let me know if need more, going take break! must missing simple.

caused by: org.springframework.beans.factory.nosuchbeandefinitionexception:   no qualifying bean of type [com.alco.repository.contactrepository]   found dependency [com.alco.repository.contactrepository]:   expected @ least 1 bean qualifies autowire candidate dependency.   dependency annotations: {@org.springframework.beans.factory.annotation.autowired(required=true)} 

my dependencies:

<dependencies>     <dependency>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-starter-data-jpa</artifactid>     </dependency>     <dependency>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-starter-data-rest</artifactid>     </dependency>     <dependency>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-starter-hateoas</artifactid>     </dependency>     <dependency>         <groupid>org.projectlombok</groupid>         <artifactid>lombok</artifactid>     </dependency>     <dependency>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-starter-security</artifactid>     </dependency>     <dependency>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-starter-web</artifactid>     </dependency>      <dependency>         <groupid>com.h2database</groupid>         <artifactid>h2</artifactid>         <scope>runtime</scope>     </dependency>     <dependency>         <groupid>org.springframework.boot</groupid>         <artifactid>spring-boot-starter-test</artifactid>         <scope>test</scope>     </dependency> </dependencies> 

contact class:

package com.example.entity;  import java.io.serializable;  import javax.persistence.entity; import javax.persistence.generatedvalue; import javax.persistence.generationtype; import javax.persistence.id;  import lombok.allargsconstructor; import lombok.getter; import lombok.noargsconstructor; import lombok.setter;  @entity @allargsconstructor @noargsconstructor @getter @setter public class contact implements serializable {  private static final long serialversionuid = -1340978779095092824l;  @id @generatedvalue(strategy=generationtype.auto) private string id; private string firstname; private string lastname; private string address; private string phonenumber; private string email;  } 

the simple interface:

package com.alco.repository;  import org.springframework.data.jpa.repository.jparepository;  import com.alco.entity.contact;  public interface contactrepository extends jparepository<contact, string> {  } 

i think you're missing enabling of jpa repositories:

@componentscan(basepackageclasses = ...) @entityscan(basepackageclasses = ...) @enableautoconfiguration @enablejparepositories(basepackageclasses = ...) public class ... { } 

this configuration class.
