这实际上取决于CrudEntityPresenter应该是什么。

如果它是普通的bean，你的代码中应该有一个与此类似的定义：

@Bean
public CrudEntityPresenter crudEntityPresenter() {
   CrudEntityPresenter crudEntityPresenter = new CrudEntityPresenter();
   //here goes the code that initializes the bean
   return crudEntityPresenter;
}

如果它应该是组件/服务，您应该使用相应的注释注释它：

@Component
public class CrudEntityPresenter {
}

或

@Service
public class CrudEntityPresenter {
}

可能背后的想法是使用JpaRepository。我非常怀疑它，但如果是这种情况，CrudEntityPresenter应该是一个扩展JpaRepository的接口：

public interface CrudEntityPresenter extends JpaRepository<MyEntity, String> {
}

在上面的示例中，我们为实体JpaRepository设置了MyEntity，其中id为String。

通过构造函数参数0表示的不满意的依赖性;嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException
