This question is somewhat related to http://stackoverflow.com/questions/305880/hibernate-annotation-placement-question.

不过，我想知道这是的更好？威盛领域性质或接入访问？
各有什么优点和缺点？

But I want to know which is better? Access via properties or access via fields? What are the advantages and disadvantages of each?

推荐答案

我preFER访问，因为我可以添加一些业务逻辑来访问我，每当我需要的。
这里有一个例子：

I prefer accessors, since I can add some business logic to my accessors whenever I need. Here's an example:

@Entity
public class Person {

  @Column("nickName")
  public String getNickName(){
     if(this.name != null) return generateFunnyNick(this.name);
     else return "John Doe";
  }
}

此外，如果你把另一个库到混合（像一些JSON转换lib或BeanMapper或推土机或其他豆类映射/克隆的基础上的getter / setter属性LIB）你必须保证该库在同步与持久性管理器（两者都使用的getter / setter）。

Besides, if you throw another libs into the mix (like some JSON-converting lib or BeanMapper or Dozer or other bean mapping/cloning lib based on getter/setter properties) you'll have the guarantee that the lib is in sync with the persistence manager (both use the getter/setter).
