如何使用Spring Boot创建测试类？

问题描述

我在创建测试课程时遇到了麻烦。 当我尝试运行时，发生以下错误：

例外 由以下原因引起：org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“ productsImpl”的bean时出错：通过字段“ paginateUtil”表示不满意的依赖关系；嵌套的异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有类型为'com.repository.paginacao.PaginateUtil'的合格Bean：期望至少有1个有资格作为自动装配候选的Bean。依赖注释：{@ org.springframework.beans.factory.annotation.Autowired（required = true）} 在org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor $ AutowiredFieldElement.inject（AutowiredAnnotationBeanPostProcessor.java:586）处 在org.springframework.beans.factory.annotation.InjectionMetadata.inject（InjectionMetadata.java:91） 在org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues（AutowiredAnnotationBeanPostProcessor.java:372）

@RunWith(SpringRunner.class)
@DataJpaTest
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
@SpringBootTest

    public class ClientTest {
        
        @Autowired
        private ClientService clientService;
        
        public ExpectedException exception = ExpectedException.none();
        
        @Test
        public void createClient() {
            Client client = new Client("Demo","Adress 1");
            clientService.save(client);
            
            Assertions.assertThat(client.getId).isNull();
        }
    }

客户端存储库

public interface Clients extends JpaRepository<Client,Long>,ClientQuery {

}

ClientQuery

public interface ClientQuery{

    public Page<Client> filter(ClientFilter filter,Pageable pageable);
    
}

ClientImpl

public class ClientImpl implements ClientQueries {

    @PersistenceContext
    private EntityManager manager;
    
    @Autowired
    private PaginateUtil paginateUtil;
    
    @SuppressWarnings("unchecked")
    @Override
    @Transactional(readOnly = true)
    public Page<Client> filter(ClientFilter filter,Pageable pageable) {
        Criteria criteria = manager.unwrap(Session.class).createCriteria(Client.class);
        
        paginateUtil.preparar(criteria,pageable);
        addFilter(filter,criteria);
                
        return new PageImpl<>(criteria.list(),pageable,total(filter));
    }
    
    private Long total(ClientFilter filter) {
        Criteria criteria = manager.unwrap(Session.class).createCriteria(Client.class);
        addFilter(filter,criteria);
        criteria.setProjection(Projections.rowCount());
        return (Long) criteria.uniqueResult();
    }

    private void addFilter(ClientFilter filter,Criteria criteria) {
        if (filter != null) {
            if (!StringUtils.isEmpty(filter.getName())) {
                criteria.add(Restrictions.ilike("name",filter.getName(),MatchMode.ANYWHERE));
            }
        }
    }

}
