找不到java Mongo Http配置类错误

Question

该项目基于PetClinic。数据从HANA DB连接，工作正常（创建表、插入数据）。当我进行Maven安装时，在我没有使用MongoDB的情况下会出现以下错误。如何排除/解决此问题

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
    }
}

我尝试下载并添加了spring会话数据。但是它仍然给出相同的错误。由于我是新手，请给我指点一下

谢谢

您的测试导致了问题。您正在尝试扫描包含大量Autoconfiguration和上下文试图加载的其他Configuration类的Spring包。你不应该这样做

你需要为你的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

您也可以使用@DataJpaTest

SpringBootTest将使用您的SpringBootApplication类，该类将为您进行组件扫描，它应放置在包结构的根目录下，并将为您扫描子包
