Document directory How does hibernate work and why? How does hibernate delay loading? In hibernate, how does one implement the relationship between classes? (For example, one-to-many and many-to-many relationships) Let's talk about the cache mechanism of hibernate.

With the application of the orm framework, development is more object-oriented, and there is no need to design a database specifically, instead of writing entities and object ing. Therefore, entity writing is a very basic and important task. Do not drag your development work back when you do it. For example, to verify the validity of data, we are used to doing it in action or controller. In fact, this work can be done in advance in entity. JSR303Bean
