我无法在添加JUnit之后运行JpaSpecificationExecutor测试，这正是CustomerRepository中的方法导致了

List findAll(CustomerSpecification customerSpecification)；

代码语言：javascript
复制
@SpringBootTest(classes = AbcTests.class)
@RunWith(SpringJUnit4ClassRunner.class)
class AbcTests {

    @Autowired
    CustomerService customerService;

    @Test
    void contextLoads(){

    }

}

这就是小胡子的样子

@Repository
public interface CustomerRepository {

    Customer save(Customer customer);
    List<Customer> findAll();
    Customer getById(Integer id);
    void deleteById(Integer id);
    List<Customer> findAll(CustomerSpecification customerSpecification);
}


@Repository
interface SqlCustomerRepository extends CustomerRepository, JpaRepository<Customer, Integer>, JpaSpecificationExecutor<Customer> {

}

上面是SqlCustomerRepository和CustomerRepository。我想使用特别化进行过滤。
