javax.persistence.PersistenceException：org.hibernate.PropertyAccessException：无法通过反射获取字段值Entity.id的getter [英] javax.persistence.PersistenceException: org.hibernate.PropertyAccessException: could not get a field value by reflection getter of Entity.id
本文介绍了javax.persistence.PersistenceException：org.hibernate.PropertyAccessException：无法通过反射获取字段值Entity.id的getter的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有以下实体：
@Entity
公共类Employee实现Serializable {
private static final long serialVersionUID = 3454567L;
@Id
@GeneratedValue（strategy = GenerationType.AUTO）
private int empId;
@Column
私人字符串用户名;
public int getEmpId（）{
return empId;
}
public void setEmpId（int empId）{
this.empId = empId;
}
public String getUsername（）{
return username;
}
public void setUsername（String username）{
this.username = username;
$ / code $ / pre
和下面的EJB： public class UserDAO implements UserDAOInterface {
@PersistenceContext（unitName =MainPersistenceUnit）
private EntityManager em;
@Override
public void persist（Employee sdf）{
try {
em.persist（sdf）;
catch（Exception e）{
Logger.getLogger（getClass（）。getName（））.log（Level.SEVERE，exception caught，e）;
抛出新的RuntimeException（e）;
$ b $ / code>
当调用persist时，引发以下根本原因的异常：

这是如何引起的，我该如何解决它？
解决方案我有同样的问题。这个错误似乎已经开始使用HB 4.3.6并且已经存活了，我正在尝试4.3.10;结果相同。
在我看来，实体字段被访问的方式在HB 4.3.6+中更改，可能与类加载器有关。在HB 4.3.6之前，将DB驱动程序jar文件嵌入到ear文件中可以正常工作（部署非常简单，干净）。在4.3.6之后，它不起作用（类没有发现异常），现在驱动程序jar文件必须放在Glassfish的lib文件夹中。

I've the following entity:
@Entity
public class Employee implements Serializable{
private static final long serialVersionUID = 3454567L;
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int empId;
@Column
private String username;
public int getEmpId() {
return empId;
}
public void setEmpId(int empId) {
this.empId = empId;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
And the following EJB:
public class UserDAO implements UserDAOInterface{
@PersistenceContext(unitName = "MainPersistenceUnit")
private EntityManager em;
@Override
public void persist(Employee sdf) {
try {
em.persist(sdf);
} catch (Exception e) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", e);
throw new RuntimeException(e);
}
}
}
When persist is called, an exception with the following root cause is thrown:

How is this caused and how can I solve it?
解决方案 I have the same issue. This bug seems to have started with HB 4.3.6 and has survived, I am trying 4.3.10; with the same results.
It seems to me that the way entities' fields are accessed changed in HB 4.3.6+, probably related with the class loader. Prior to HB 4.3.6, embedding the DB driver jar file in the ear file works fine (very easy and clean for deployment). After 4.3.6, it doesn't work (with a class not found exception), now the driver jar file has to be put in the lib folder of Glassfish.
