Zero-configuration Annotation and Hibernate Annotation configuration for hibernate We recommend that you use Annotation to manage the ing between object classes and data tables in JPA specifications, so as to avoid maintaining two files (Java object classes and XML ing files) at the same time ), combine the ing information (written in Annotation) with the object class. Below I will use eclipse to build a sm
