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();}

DAO实现类

@Repositorypublic class BannerDaoImpl implements BannerDao {@Autowiredprivate 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);}}

单元测试类

@SpringBootTest(classes = {LivegoodsBannerApp.class})@RunWith(SpringRunner.class)public class TestDao {@Autowiredprivate BannerDao bannerDao;@Testpublic void testSelect(){List<Banner> banners = bannerDao.getBanners();for (Banner b : banners){System.out.println(b);}}}

demo_banner的pom-xml

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><parent><artifactId>demo</artifactId><groupId>com.demo</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>demo_banner</artifactId><version>1.0-SNAPSHOT</version><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId></dependency><dependency><groupId>com.demo</groupId><artifactId>demo_mongodb</artifactId><version>1.0-SNAPSHOT</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId></dependency></dependencies></project>

另一个子项目demo_mongodb配置文件如下：application-mongodb.yml

spring:data:mongodb:host: 192.168.1.13port: 27017username: adminpassword: adminauthentication-database: admindatabase: livegoods

demo_mongodb的pom-xml

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。
