问题描述

@EntityScan("modele")

Test并不是说真的是Spring Bean，而是 JPA Entity 。@ComponentScan验看@Configuration，@Component，@Service和@Repository，@Controller和@RestController。@EntityScan将寻找实体。

@H_403_31@

• Application.java在你的包的根：com.domain.project;
• 您的存储库在com.domain.project.dao;
• 您在下的实体com.domain.project.domain。

然后，您将不需要@EntityScan，@ComponentScan而@EnableJpaRepositoriesSpringBoot将仅提取com.domain.project中发现的所有内容。*

解决方法

下面是跟踪：

org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“
testController”的bean时出错：通过字段“
testDao”表示的不满意的依赖关系；嵌套的异常是org.springframework.beans.factory.BeanCreationException：创建名称为’testDAO’的bean时出错：调用init方法失败；嵌套异常为java.lang.IllegalArgumentException：不是托管类型：class
modele.Test

…

由以下原因引起：org.springframework.beans.factory.BeanCreationException：创建名称为’testDAO’的bean时出错：调用init方法失败；嵌套异常为java.lang.IllegalArgumentException：不是托管类型：class
modele.Test

…

原因：java.lang.IllegalArgumentException：不是托管类型：class modele.Test

根据我的理解，根本的错误是Not a managed type: class modele.Test，与Test不被视为一个实体有什么关系？

这是我的项目：

应用程序

@SpringBootApplication
@ComponentScan("boot")
@ComponentScan("dao")
@ComponentScan("modele")
@EnableJpaRepositories("dao")
public class Application {

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

}

TestDAO.java

@Transactional
public interface TestDAO extends CrudRepository<Test,Long > {

  /**
   * This method will find an User instance in the database by its email.
   * Note that this method is not implemented and its working code will be
   * automagically generated from its signature by Spring Data JPA.
   */
  public Test findByEmail(String email);

}

Test.java

@Entity
@Table(name = "test")
public class Test {

    // An autogenerated id (unique for each user in the db)
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    @NotNull
    private String email;

    @NotNull
    private String name;

    // Public methods

    public Test() {
    }

    public Test(long id) {
        this.id = id;
    }

    public Test(String email,String name) {
        this.email = email;
        this.name = name;
    }
//setters and getters

我将不胜感激。谢谢！
