在运行时获取有关entites的休眠信息 [英] Getting hibernate information about entites at runtime

问题描述

我正在寻求一种在运行时获取有关我的hibernate实体类的信息的方法。详细我需要的信息，如$ / b>

ABC类具有属性a，b和c，其中c是
列表和关联给班级XYZ

给班级

  public class ABC {
 private int a; 
私人字符串b; 
 
 @OneToMany 
私人清单< XYZ> C; 
} 
  

运行时需要的全部内容。我确信Hibernate在运行时知道所有这些信息，但我不知道如何获得这些信息。

PersistentClass userMapping = cfg.getClassMapping（ABC.class）;


cfg是Hibernate Configuration的一个实例。

PersistentClass 包含所有信息你需要。

I am seeking a way to get information about my hibernate entity classes at runtime. In detail I would need information like

Class ABC has the properties a, b and c with c being a list and association to class XYZ

for the class

public class ABC {
    private int a;
    private String b;

    @OneToMany
    Private List<XYZ> c;
}

All that is needed at runtime. I am sure Hibernate knows all that at runtime, but I am not aware how to get these information.

解决方案

PersistentClass userMapping = cfg.getClassMapping(ABC.class);

cfg is an instance of Hibernate Configuration.

PersistentClass has all the info you need.
