问题
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
but there's a problem with loading the Application Context. I think it's a springBoot/Bean Problem.
Here's my Testing 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());
}
}
The Application-class:
@SpringBootApplication
@EnableWebMvc
public class PrototypApplication implements WebMvcConfigurer {
public static void main(String[] args) {
SpringApplication.run(PrototypApplication.class, args);
}
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>{
}
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;
}
}
The Problem is the following Error when I start the ComponentTest: Here's a Sample of the Error Stack:

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
回答1:
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.)
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.
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).
