Spring启动Autowired存储库不使用SpringRunner和JPA数据

当我尝试运行测试时，我遇到了错误。我是春季靴子的新手，所以无法理解确切的问题。

我的单元测试

package api.usecase.createtask;

import api.model.Task;
import api.usecase.createtask.contracts.CreateTaskRequest;
import api.usecase.createtask.contracts.CreateTaskResponse;
import api.usecase.createtask.repository.CreateTaskRepository;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.List;

@RunWith(SpringRunner.class)
public class CreateTaskTest {

    @Autowired
    private CreateTaskRepository taskRepository;

    @Test
    public void createSuccessfulTask() {
        CreateTaskRequest createTaskRequest = new CreateTaskRequest();
        createTaskRequest.setDescription("Wash car");
        createTaskRequest.setAmount(10);
        createTaskRequest.setRecurrenceType("ONE_OFF");
        createTaskRequest.setStatus("NOT_COMPLETED");
        CreateTaskResponse createTaskResponse = new CreateTaskResponse();
        CreateTask createTask = new CreateTask(this.taskRepository);
        createTask.handle(createTaskRequest, createTaskResponse);
        List<Task> tasks = this.taskRepository.findAll();
        tasks.forEach(System.out::println);
    }
}

我的存储库类

package api.usecase.createtask.repository;


import api.model.Task;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface CreateTaskRepository extends JpaRepository <Task, Long>{
    List<Task> findAll();
}

主要应用程序文件。我也试过@EnableJpaRepositories（basePackages = {＆＃34; api.usecase.createtask.repository＆＃34;}，考虑嵌套存储库=真）选项，但仍然无效。 

package api;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

创建任务逻辑类

package api.usecase.createtask;

import api.model.Task;
import api.usecase.createtask.contracts.CreateTaskRequest;
import api.usecase.createtask.contracts.CreateTaskResponse;
import api.usecase.createtask.repository.CreateTaskRepository;


public class CreateTask {
    private CreateTaskRepository repository;

    public CreateTask(CreateTaskRepository repository) {
        this.repository = repository;
    }

    public void handle(CreateTaskRequest createTaskRequest, CreateTaskResponse createTaskResponse) {
        Task task = new Task(
                createTaskRequest.getDescription(),
                createTaskRequest.getAmount(),
                createTaskRequest.getRecurrenceType(),
                createTaskRequest.getStatus()
        );
        this.repository.save(task);
    }
}

模型

package api.model;

import org.springframework.stereotype.Component;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "CHILD_Tasks")
public class Task {
    @Id
    @Column(name = "id")
    private long id;

    @Column(name = "description")
    private String description;

    @Column(name = "amount")
    private float amount;

    @Column(name = "recurrenceType")
    private String recurrenceType;

    @Column(name = "status")

    public Task(String description, Float amount, String recurrenceType, String status) {
        this.description = description;
        this.amount = amount;
        this.recurrenceType = recurrenceType;
        this.status = status;

您尚未指定Spring配置。春天不知道你有什么豆子或者在哪里找到它们。

如果您只想测试存储库，则需要添加DataJpaTest注释。文档：http://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/test/autoconfigure/orm/jpa/DataJpaTest.html 

@RunWith(SpringRunner.class)
@DataJpaTest
@AutoConfigureTestDatabase(connection = EmbeddedDatabaseConnection.H2)
public class CreateTaskTest {
...
  

默认情况下，它将配置内存中的嵌入式数据库，扫描   @Entity类并配置Spring Data JPA存储库。定期   @Component bean不会加载到ApplicationContext中。

     

数据JPA测试在每次测试结束时都是事务性和回滚   默认[...]

     

Data JPA测试也可能会注入提供的TestEntityManager bean   标准JPA EntityManager的替代品，专门设计   用于测试。如果你想在外面使用TestEntityManager   @DataJpaTests你也可以使用@AutoConfigureTestEntityManager   注解。 [...] 

@RunWith(SpringRunner.class) @DataJpaTest public class ExampleRepositoryTests {

    @Autowired
    private TestEntityManager entityManager;

    @Autowired
    private UserRepository repository;

    @Test
    public void testExample() throws Exception {
        this.entityManager.persist(new User("sboot", "1234"));
        User user = this.repository.findByUsername("sboot");
        assertThat(user.getUsername()).isEqualTo("sboot");
        assertThat(user.getVin()).isEqualTo("1234");
    } }

此外，如果您需要从所有组件创建bean，可以使用SpringBootTest。

我建议你阅读Spring Boot测试参考（link）。 Spring有很好的文档。
