Concept

The retrieval entity class, which is the class annotated with @SearchBean, is also known as SearchBean. In the previous section, we experienced the single-table retrieval function of Bean Searcher. However, compared with traditional ORMs, it is actually better at handling complex joint-table retrievals and some strange subqueries. At this time, the definition of SearchBean is also very easy.

In addition, Bean Searcher also supports omitting annotations. An entity class without any annotations can also be automatically mapped to the database.

Important Note

The entity class (SearchBean) mentioned here is a VO (View Object) that has a cross-table mapping relationship with the database. It is fundamentally different in concept from the entity class (Entity) or domain class (Domain) in traditional ORMs. Refer to the Introduction > Why Use > Design Concept (Starting Point) section.
