Hibernate PropertyAccessException：IllegalArgumentException

问题描述

我有一个直到最近才开始工作的hibernate映射 - 虽然我确定这是我做出的一些更改的结果，但我似乎无法找到它。

映射文件将字段定义为：

 < id name =idcolumn =id > 
< generator class =native/> 
< / id> 
  

该类将此字段定义为：

 私人长ID; 
 public Long getId（）{
 return id; 
} 
 public void setId（Long id）{
 this.id = id; 
} 
  

运行此代码时，出现以下错误：

  org.hibernate.PropertyAccessException：
调用MyClass.id的setter时发生IllegalArgumentException 
  
 
 
 
与此对应的数据库字段定义为： 
 
 
 `id` bigint（20）NOT NULL AUTO_INCREMENT PRIMARY KEY 
  
类似的结构和定义，并没有与他们的问题。但是，可能是由于我最近做出的一些更改而导致的，这个特定的映射将不再正常工作。
 
 
 
有什么建议吗？ 
 
 
 
 
 < / p> 
 
 id name =idtype =java.lang.Long> 
< column name =id/> 
< generator class =native/> 
< / id> 
  
 Hibernate可能会设置错误的值。
 
I have a hibernate mapping which was working until recently - and while I'm sure this is the result of some change I've made, I can't seem to find it.
The mapping file defines a field as:
<id name="id" column="id">
    <generator class="native" />
</id>
The class defines this field as:
private Long id;
public Long getId() {
    return id;
}
public void setId(Long id) {
    this.id = id;
}
When I run this code, I get the following error:
org.hibernate.PropertyAccessException: 
    IllegalArgumentException occurred while calling setter of MyClass.id
The database field to which this corresponds is defined as:
`id` bigint(20) NOT NULL AUTO_INCREMENT PRIMARY KEY
I have several other classes with similar structures and definitions, and have no issues with them. However, likely resulting from some recent change I made, this one particular mapping will no longer work properly.
Any suggestions?
 解决方案 
I am not sure but you can try this : 
<id name="id" type="java.lang.Long">
            <column name="id" />
            <generator class="native" />
</id>
Hibernate may be setting wrong value.
