java - Spring Boot DataJpaTest(用于存储库)失败并显示 java.lang.IllegalStateException : Failed to load ApplicationContext

标签 java spring spring-boot jpa junit-jupiter

我想测试我的 SpringBootApplication 的存储库层。 我使用了以下文章: https://www.baeldung.com/spring-boot-testing#integration-testing-with-datajpatest

但是加载应用程序上下文时出现问题。我认为这是一个 springBoot/Bean 问题。

这是我的测试类(class):

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(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:

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;
    }
}

问题是当我启动 ComponentTest 时出现以下错误: 这是错误堆栈的示例:

我检查了不同的 Spring-boot-test 注释，例如 @SpringBootTest，但没有任何变化。 有没有人有同样的问题或解决方案？ 如果您需要更多信息/代码片段/错误堆栈，请与我联系。 谢谢

最佳答案

如果您删除 @EnableWebMvc，您的测试将起作用 - 正如 Darren 在评论中指出的那样，也不需要它 - 如果您的配置器上有一些配置，那么您可以将其移动到单独的类(class)。 (Spring Boot 将根据类路径等中的类自动配置自身。)

为什么它现在不起作用:@SpringBootTest 和 Spring Boot 测试片将自动尝试查找您的主应用程序类并从中应用配置，如 Spring's documentation 中所述。 .

最好有单独的配置类，这些类不应在所有测试中加载。根据正在执行的测试，将自动包含此配置(例如，将为 WebMvcTest 切片加载 WebMvcConfigured，但不会为 DataJpaTest 切片加载)。
