Spring Boot DataJpaTest(用于存储库)失败，并出现java.lang.IllegalStateException:无法加载ApplicationContext [英] Spring Boot DataJpaTest (for Repositories) fail with java.lang.IllegalStateException: Failed to load ApplicationContext
本文介绍了Spring Boot DataJpaTest(用于存储库)失败，并出现java.lang.IllegalStateException:无法加载ApplicationContext的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我要测试SpringBootApplication的存储库层. 我使用了以下Articel: https://www.baeldung.com/spring-boot- testing#integration-testing-with-datajpatest
I want to test the Repository-Layer of my SpringBootApplication. I used the following Articel: https://www.baeldung.com/spring-boot-testing#integration-testing-with-datajpatest
，但是加载应用程序上下文存在问题.我认为这是一个springBoot/Bean问题.
but there's a problem with loading the Application Context. I think it's a springBoot/Bean Problem.
这是我的测试班:
package ak19f.repositories;
import ak19f.entities.ComponentOur;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.boot.test.autoconfigure.orm.jpa.TestEntityManager;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import javax.sql.DataSource;
import static org.assertj.core.api.Assertions.assertThat;
@DataJpaTest
@ExtendWith(SpringExtension.class)
public class ComponentRepositoryTest {
@Autowired
private TestEntityManager entityManager;
@Autowired
private ComponentRepository componentRepository;
@Test
public void testGetOne() {
// given
ComponentOur c1 = new ComponentOur();
c1.setId(1);
c1.setComponentBrand("d");
c1.setComponentDescription("s");
c1.setSerialNumber("123");
entityManager.persist(c1);
entityManager.flush();
// when
ComponentOur found = componentRepository.getOne(1);
// then
assertThat(found.getComponentBrand())
.isEqualTo(c1.getComponentBrand());
assertThat(found.getComponentDescription())
.isEqualTo(c1.getComponentDescription());
assertThat(found.getComponentTyp())
.isEqualTo(c1.getComponentTyp());
assertThat(found.getSerialNumber())
.isEqualTo(c1.getSerialNumber());
}
}
应用程序类:
@SpringBootApplication
@EnableWebMvc
public class PrototypApplication implements WebMvcConfigurer {
public static void main(String[] args) {
SpringApplication.run(PrototypApplication.class, args);
}
和ComponentRepository接口:
And the ComponentRepository Interface:
package ak19f.repositories;
import ak19f.entities.ComponentOur;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface ComponentRepository extends JpaRepository<ComponentOur,Integer>{
}
和ComponentEntity:
And the ComponentEntity:
package ak19f.entities;
import ak19f.entities.ServiceAgreement;
import javax.persistence.*;
import java.io.Serializable;
import java.util.List;
@Entity
@Table(name = "component_our")
public class ComponentOur implements Serializable, EntityBase {
@Id
@Column(name = "component_id" , nullable = false)
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
@Column(name = "component_typ" , nullable = false)
private String componentTyp;
@Column(name = "component_description")
private String componentDescription;
@Column(name = "component_brand")
private String componentBrand;
@Column( name = "serial_number")
private String serialNumber;
public ComponentOur(){}
public ComponentOur(String componentTyp, String componentDescription, String componentBrand){
this.componentTyp = componentTyp;
this.componentDescription = componentDescription;
this.componentBrand= componentBrand;
}
@Override
public Integer getId() {
return id;
}
@Override
public void setId(Integer id) {
}
public String getComponentTyp() {
return componentTyp;
}
public void setComponentTyp(String componentTyp) {
this.componentTyp = componentTyp;
}
public String getComponentDescription() {
return componentDescription;
}
public String getComponentBrand() {
return componentBrand;
}
public void setComponentBrand(String componentBrand) {
this.componentBrand = componentBrand;
}
public void setComponentDescription(String componentDescrip) {
this.componentDescription = componentDescrip;
}
public String getSerialNumber() {
return serialNumber;
}
public void setSerialNumber(String serialNumber) {
this.serialNumber = serialNumber;
}
}
问题是我启动ComponentTest时出现以下错误: 这是错误堆栈的示例:
The Problem is the following Error when I start the ComponentTest: Here's a Sample of the Error Stack:

我签出了不同的Spring-boot-test注释，例如@SpringBootTest，但没有任何变化. 有没有谁遇到相同的问题或解决方案? 如果您需要更多信息/代码段/错误堆栈，请与我联系. 谢谢
I checked out different Spring-boot-test annotations like @SpringBootTest, but nothing changed. Is there anyone out there who has the same issue or a solution? If you need further information/ code snippets / error stacks please contact me. thanks
推荐答案
如果删除@EnableWebMvc，您的测试将起作用-达伦(Darren)在评论中也指出了该测试-并且您的计算机上有一些配置然后可以将其移动到单独的类. (Spring Boot会根据classpath等中的类自动配置自身.)
Your test will work if you remove @EnableWebMvc - it is not needed as pointed out by Darren in the comments too - and if you have some configuration on your configurer then you can move it to a separate class. (Spring Boot will configure itself automatically depending on classes at classpath etc.)
为什么现在不起作用:@SpringBootTest和Spring Boot测试片将自动尝试找到您的主要应用程序类并从中应用配置，如
Why it's not working now: @SpringBootTest and Spring Boot test slices will automatically try to find your main application class and apply configuration from it as noted in Spring's documentation.
最好有单独的配置类，这些类不应在所有测试中都加载.根据正在执行的测试，将自动包含此配置(例如，将为WebMvcTest slice加载WebMvcConfigured，而不为DataJpaTest slice加载WebMvcConfigured).
It's best to have separate classes for configuration that should not be loaded in all tests. This configuration will be included automatically depending on the test being executed (WebMvcConfigured will be loaded for WebMvcTest slice but not for DataJpaTest slice for example).
