下一次我们会来分析关闭Lazy Loading的情况下,如何显示加载相关实体,即Explicit Loading。 上一回我们在《Entity Framework加载相关实体——Lazy Loading》分析了Lazy Loading,这一回我们来分析一下在关闭Lazy Loading的情况下,如果显式加载实体。 数据库我们依旧使用Lazy Loading中使用的数
In this article, we explored eager and lazy loading in detail, covering their benefits and differences. We also implemented both lazy and eager loading in a single-page application like React using only components. These techniques are essential in optimizing the performance of web applications. La...

Eager Loading is a data loading strategy in Entity Framework where we load the related entities from the database along with the main entity in a single query. This is in contrast to Lazy Loading, where we load the related entities only when explicitly accessed. It is particularly useful wh...
Choosing the rightFetchTypeis one of the most important decisions when defining your entity mapping. It specifies when your JPA implementation, e.g., Hibernate, fetches associated entities from the database. You can choose betweenEAGERandLAZYloading. The first one fetches an association immediately,...
