java - Mongo Http配置类未找到错误

Question

该项目基于 PetClinic 。数据从 HANA DB 连接并且工作正常(创建表、插入数据)。当我执行 Maven Install 时，我收到以下错误，但我没有使用 MongoDB。如何排除/解决这个问题。

生产配置测试:

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.samples.petclinic.vet.VetRepository;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@RunWith(SpringRunner.class)
@SpringBootTest
@ComponentScan({"org.springframework*"})
@EntityScan("com.springframework*")
@EnableJpaRepositories("com.springframework*")
public class ProductionConfigurationTests {

    @Autowired
    private VetRepository vets;

    @Test
    public void testFindAll() throws Exception {
        vets.findAll();
        vets.findAll(); // served from cache
    }
}

我尝试下载并添加 spring-session-data.jar 但它仍然给出相同的错误。请指导，因为我是这个 Maven/Spring 的新手

谢谢

您的测试导致了该问题。您正在尝试扫描包含大量 Autoconfiguration 和上下文尝试加载的其他 Configuration 类的 Spring 包。你绝对不应该这样做。

您需要为测试做的就是这个添加

@RunWith(SpringRunner.class)
@SpringBootTest

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

您还可以使用@DataJpaTest

SpringBootTest 将使用您的 SpringBootApplication 类，该类将为您进行组件扫描，它应该放置在您的包结构的根目录中，并且它将扫描子包以查找你。
