项目是通过Maven的,我想从Mongodb数据库里面查询出来存进去的数据,然后做单元测试DAO接口,一直报错拒绝连接。 本地测试,可以访问Mongodb,使用 navicat 测试连接也没有问题。 DAO接口 - public interface BannerDao {
-
- List<Banner> getBanners();
- }
-
复制代码DAO实现类 - @Repository
- public class BannerDaoImpl implements BannerDao {
-
- @Autowired
- private MongoTemplate mongoTemplate;
-
- /**
- * 查询数据
- * @return
- */
- public List<Banner> getBanners() {
- Date now = new Date();
- Query query = Query.query(
- Criteria.where("beginTime").lt(now)
- .and("endTime").gt(now)
- );
-
- return mongoTemplate.find(query,Banner.class);
- }
- }
-
-
复制代码单元测试类 -
- @SpringBootTest(classes = {LivegoodsBannerApp.class})
- @RunWith(SpringRunner.class)
- public class TestDao {
-
- @Autowired
- private BannerDao bannerDao;
-
- @Test
- public void testSelect(){
- List<Banner> banners = bannerDao.getBanners();
- for (Banner b : banners){
- System.out.println(b);
- }
- }
-
- }

复制代码一开始是无法访问到,后面通过配置开放防火墙端口,并将mongodb配置文件添加成任何IP都可以访问,但运行后还是无法查询到数据库的数据,显示连接超时,拒绝连接什么的。 我想测试DAO接口,看是否能查询出数据库里面的轮播图的图片路径、开始时间、过期时间这些的。不知道是哪里出错了,希望能帮忙看下是什么原因。
