如何修复 Springboot 中的 CrudRepository.save(java.lang.Object) is no accessor 方法? [英] how to fix the CrudRepository.save(java.lang.Object) is no accessor method in springboot?

问题描述

我参考了这个 springboot 教程，我在我的项目中使用了 spring data，我试图将 data 添加到数据库.使用以下 . bt 当我尝试这样做时，我收到一个错误说

im reffering to this springboot tutorial and im using spring data in my project, im trying to add data to database . using the following . bt when im trying to do that i get an error saying

调用方法 public abstract java.lang.Objectorg.springframework.data.repository.CrudRepository.save(java.lang.Object)不是访问器方法！

Invoked method public abstract java.lang.Object org.springframework.data.repository.CrudRepository.save(java.lang.Object) is no accessor method!

这是我的代码，

//my controller

@RequestMapping("/mode")
    public String showProducts(ModeRepository repository){
        Mode m = new Mode();
        m.setSeats(2);
        repository.save(m); //this is where the error getting from
        return "product";
    }


//implementing crud with mode repository
@Repository
public interface ModeRepository extends CrudRepository<Mode, Long> {

}

 //my mode class
@Entity
@Table(name="mode")
public class Mode implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(unique=true, nullable=false)
    private int idMode; 


    @Column(nullable=false)
    private int seats;

    //assume that there are getters and setters
}

我是 springboot 的新手，谁能告诉我我做错了什么，如果有人能给我一个链接来了解 springdata除了 spring 文档

im new to springboot and can someone tellme what am i doing wrong, appreciate if someone could provide me a link to get to know about springdata other than spring documentation

推荐答案

更改控制器代码，使 ModeRepository 成为私有的自动装配字段.

Change your controller code so that the ModeRepository is a private autowired field.

    @Autowired //don't forget the setter
    private ModeRepository repository; 

    @RequestMapping("/mode")
    public String showProducts(){
        Mode m = new Mode();
        m.setSeats(2);
        repository.save(m); //this is where the error getting from
        return "product";
    }
