无法创建JPA/CrudRepository bean

Question

我正在使用spring Data JPA创建第一次spring rest服务。

并降低误差。

我的类和接口是：

1. 控制器

@RestController
public class AddProduct {
    
    
    @Autowired
    private ProductRepositroy product_repo;
    
    @GetMapping("/add")
    public String addproduct() {
        
        
        Product p1 = new Product();
        p1.setId(1);
        p1.setName("Amit");
        
        
        Product p2 = new Product();
        p1.setId(2);
        p1.setName("Sumit");
        
        
        product_repo.save(p1);
        product_repo.save(p2);
        
        
        return "added successfully the recod";
        
    }

}

@Entity
public class Product {
    
    @Id
    private int id;
    private String name;
    
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    

}

public interface ProductRepositroy extends CrudRepository<Product, Integer> {

}

@SpringBootApplication
public class Demo1Application {

    public static void main(String[] args) {
        SpringApplication.run(Demo1Application.class, args);
    }
    
    

}

Answer 1

在ProductRepositroy接口上添加@repository注释。另外，不是扩展CrudRepository，而是扩展JParepository。
