Spring boot - MongoDb 在 RepositoryInvokerFactory 上获得 ClassNotFoundException

Question

我正在尝试使用 MongoDB 连接到 mLab 来设置 Spring Boot 应用程序。但是当我尝试运行这个测试（或任何其他测试）时

@RunWith(SpringRunner.class)
@SpringBootTest 

public class SyncrewApplicationTests {
  @Test
  public void contextLoads() {
  } 
}

我得到这个错误：

Caused by: java.lang.ClassNotFoundException: org.springframework.data.rest.core.invoke.RepositoryInvokerFactory

我的 Spring 启动应用程序：

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

用户 MongoDB 存储库

@RepositoryRestResource(exported = false)
public interface UserRepository extends MongoRepository<User, Integer> {
    User findUserByUsername(String username);
    User findUserByEmail(String email);
}

用户类

@Document(collection = "users")
public class User implements Serializable, UserDetails {
    @Id
    private String id;

    private String username;

    public User(){}

    public User(String username){
        this.username = username;
    }
    // getters and setters

我认为我的问题出在我的 pom.xml 中，但我不知道在哪里.. 这是我的依赖项

您的文件看起来很完美，只需在 pom 中添加版本就可以了。

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
        <version>RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
        <version>RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>RELEASE</version>
    </dependency>
