如何让Hibernate忽略一个方法？ [英] How to make Hibernate ignore a method?

问题描述

这个问题本质上与相反这一个。

我有一个像这样的方法：

  public boolean isVacant（）{
 return getEmployeeNum（）！= null&& 。getEmployeeNum（）等于（ 00000000）; 
} 
  

当我加载它时，Hibernate抱怨我没有属性叫做空置。但我不想要一个名为 vacant 的属性 - 我不需要存储这些数据 - 它只是逻辑。

< Hibernate说：

org.hibernate.PropertyNotFoundException：无法在类com.mycomp.myclass中找到属性为空的setter。 。

是否有可以添加到 isVacant（）方法的注释让Hibernate忽略它？

解决方案

在方法中添加 @Transient 那么Hibernate应该忽略它。

引用 Hibernate文档：

每个非静态非除非您将它标注为 @Transient 。

，但实体的暂时属性（取决于访问类型的字段或方法） blockquote>

This question is essentially the opposite of this one.

I have a method like so:

public boolean isVacant() {
    return getEmployeeNum() != null && getEmployeeNum().equals("00000000");
}

When I load it up, Hibernate is complaining that I have no attribute called vacant. But I don't want an attribute called vacant - I have no need to store that data - it's simply logic.

Hibernate says:

org.hibernate.PropertyNotFoundException: Could not find a setter for property vacant in class com.mycomp.myclass...

Is there an annotation I can add to my isVacant() method to make Hibernate ignore it?

解决方案

Add @Transient to the method then Hibernate should ignore it.

To quote the Hibernate Documentation:

Every non static non transient property (field or method depending on the access type) of an entity is considered persistent, unless you annotate it as @Transient.
