/**  *   */ package com.corrisoft.air.db.integration;  import static org.junit.assert.*;  import org.junit.test; import org.junit.runner.runwith; import org.springframework.beans.factory.annotation.autowired; import org.springframework.test.context.contextconfiguration; import org.springframework.test.context.junit4.springjunit4classrunner; import org.springframework.test.context.transaction.transactionconfiguration; import org.springframework.transaction.annotation.transactional;  import com.corrisoft.air.db.jpaconfiguration; import com.corrisoft.air.db.repository.personsrepository; import com.corrisoft.air.model.person;      /**      * @author corrisoft android development      *      */     @runwith(springjunit4classrunner.class)     @contextconfiguration(classes = {jpaconfiguration.class})     @transactional     @transactionconfiguration(defaultrollback = true)     public class personsrepositoryintegerationtests {            @autowired           personsrepository personsrepository;            @test           public void thatitemisinsertedintorepoworks() throws exception {             int id = 42;              person person = new person();             person.setid(id);              person.setfirstname("zaphod");             person.setlastname("beeblebrox");              personsrepository.save(person);              person retrievedperson = personsrepository.findbyid(id);              assertnotnull(retrievedperson);             assertequals(id, retrievedperson.getid());           }     }  tests repository i've created here:      /**      *       */     package com.corrisoft.air.db.repository;      import com.corrisoft.air.model.person;     import org.springframework.data.repository.crudrepository;      /**      * @author corrisoft android development      *      */     public interface personsrepository extends crudrepository<person, integer>{         person findbyid(long id);     } 

and i'm getting following exception:

i've found several issues tutorial , thinking another.

you scanning wrong package repositories:

... basepackages = "com.corrisoft.db.repository" ... 

whereas correct 1

import com.corrisoft.air.db.repository.personsrepository;
