CustomerRepository

public interface CustomerRepository extends PagingAndSortingRepository<Customer, Long>{
        Customer findByFirstName(String firstName);
    }

Customer.java

@Document
public class Customer extends AbstractEntity{

    private String firstName, lastName;

    public Customer(String firstName, String lastName) {

        Assert.hasText(firstName,"First Name cannot be null or empty");
        Assert.hasText(lastName, "Last Name cannot be null or empty");

        this.firstName = firstName;
        this.lastName = lastName;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

}

Thanks in advance.

I think the problem is that your test class name is CustomerRepository - the same as you real CustomerRepository which you are testing.

Therefore Spring is trying to find a bean of your test class type (not the repository type) and cannot find it.

Try to rename test class to something different. For example:

@ContextConfiguration(locations{"classpath:application/springcontexts/appContext-persistence.xml"})
public class CustomerRepositoryTest extends AbstractTestUnit{
        @Autowired 
        CustomerRepository customerRepository;
        @Test
        public void testContextLoader() {
        //....
        }
}
