Hibernate / JPA - 注释bean方法vs字段 [英] Hibernate/JPA - annotating bean methods vs fields

问题描述

我有一个关于Hibernate使用的简单问题。我一直以两种方式之一看到使用JPA注释的人注释类的字段，并注释相应bean的get方法。

我的问题是如下所示：注释字段和bean方法与JPA批注（如@Id）之间是否存在差异。

$ b 示例：

  @Entity 
 public class User 
 {
 
 ** @ ID ** 
 private int id; 
 
 public int getId（）{
 return this.id; 
} 
 
 public void setId（int id）{
 this.id = id; 
} 
 
} 
  

------- ---- OR -----------

  @Entity 
 public class User 
 {
 
 
 private int id; 
 
 ** @ ID ** 
 public int getId（）{
 return this.id; 
} 
 
 public void setId（int id）{
 this.id = id; 
} 
 
} 
  

解决方案

是的，我相信你想在字段和属性访问上进行搜索：

Hibernate Annotations - 哪个更好，字段或属性访问？

Spring首选项是字段访问权限。这就是我所追求的。

I have a simple question about usage of Hibernate. I keep seeing people using JPA annotations in one of two ways by annotating the fields of a class and also by annotating the get method on the corresponding beans.

My question is as follows: Is there a difference between annotating fields and bean methods with JPA annoations such as @Id.

example:

@Entity
public class User
{

**@ID**
private int id;

public int getId(){
return this.id;
}

public void setId(int id){
this.id=id;
}

}

-----------OR-----------

@Entity
public class User
{


private int id;

**@ID**
public int getId(){
return this.id;
}

public void setId(int id){
this.id=id;
}

}

解决方案

Yes, I believe you want to search on field versus property access:

Hibernate Annotations - Which is better, field or property access?

The Spring preference is field access. That's what I follow.
