java - 表达不满意的依赖性

我的课如下

public abstract interface IGenRepository  <T> {

 public abstract List<T> getAll(String filter);
}

和

@Repository
public abstract class GenRepository<T> implements IGenRepository<T> {
protected abstract Class<T> myFunction();
 @Override
public List<T> getAll(String filter) {

.......}}

所有这些类都是通用的，现在我想在项目中使用这些类

public  interface IProductRepository extends IGenRepository<Product> {}

该类的含义是：

@Repository
public class ProductRepository extends GenRepository<Product> {}

在使用此类时，请按以下步骤使用：

@Autowired private IProductRepository iProductRepository;

有这个错误

Exception encountered during context initialization - cancelling refresh attempt:
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'productService': Unsatisfied dependency expressed through field 'iProductRepository';
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'org.tax.repositories.IProductRepository' available:
expected at least 1 bean which qualifies as autowire candidate. Dependency annotations:
 {@org.springframework.beans.factory.annotation.Autowired(required=true)}

最佳答案

您没有实现IProductRepository ProductRepository类。
更改代码如下-

@Repository
public class ProductRepository implements IProductRepository extends GenRepository<Product> {}
