问题描述
@EntityScan("modele")
@H_502_4@Test@H_502_4@并不是说真的是Spring Bean，而是 JPA Entity
。@ComponentScan@H_502_4@验看@Configuration@H_502_4@，@Component@H_502_4@，@Service@H_502_4@和@Repository@H_502_4@，@Controller@H_502_4@和@RestController@H_502_4@。@EntityScan@H_502_4@将寻找实体。
- Application.java在你的包的根：
com.domain.project@H_502_4@; - 您的存储库在
com.domain.project.dao@H_502_4@; - 您在下的实体
com.domain.project.domain@H_502_4@。
然后，您将不需要@EntityScan@H_502_4@，@ComponentScan@H_502_4@而@EnableJpaRepositories@H_502_4@SpringBoot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！
