java - JPA:无法反序列化

Question

尝试运行此查询时，我从 Hibernate 实现中收到此异常:

em.createQuery("from User u where u.userID = :userId and u.passwd=:passwd", User.class)
.setParameter("userId", userID)
.setParameter("passwd", passwd)
.getSingleResult();

用户.java

@Entity
@Table(name="Uzer")
public class User implements Serializable {
private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private int id;

private boolean active;

private String details;

private String email;

private String name;

private String passwd;

private String userID;

//bi-directional many-to-one association to Auth
@OneToMany(mappedBy="uzer",fetch=FetchType.EAGER)
private Collection<Auth> auths;

//bi-directional many-to-one association to Role
@ManyToOne
@JoinColumn(name="Role$id")
private Role role;
...//getters and setters
}

Auth.java

@Entity
public class Auth implements Serializable {
private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private int id;

private String action;

@Enumerated(EnumType.ORDINAL)
private Mode mode;

private String module;

private String screen;

@Enumerated(EnumType.ORDINAL)
private Type type;

@ManyToOne
@JoinColumn(name="Role$id")
private Role role;

@ManyToOne
@JoinColumn(name="Uzer$id")
private User uzer;


@Column(name="Uzer$id",updatable=false, insertable=false)
@Transient
private User user;
...//getters and setters
}

角色.java

@Entity
public class Role implements Serializable {
private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private int id;

private String description;

private String email;

private String name;

@JoinColumn(name="Role$id", insertable=false ,updatable=false)
@Column(name="Role$id")
private Role role;

private String roleID;

@Enumerated(EnumType.ORDINAL)
private Type type;

//bi-directional many-to-one association to Auth
@OneToMany(mappedBy="role")
private Collection<Auth> auths;

//bi-directional many-to-one association to Uzer
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="Manager$id")
private User manager;

//bi-directional many-to-one association to Uzer
@OneToMany(mappedBy="role")
private List<User> uzers;

@Transient
private Collection<Role> roles;

@Transient
private boolean recursive;

@Transient
private Collection<User> users;
...//getters and setters
}

这个问题我花了五天时间，没有解决。错误在哪里？

Answer 1

我不确定这是否能解决您的问题。但您的映射中有些内容没有意义:

1. 在 Role 实体中，以下内容没有意义，因为即使您没有任何关系注释 (@OneToOne或@ManyToOne):

   @JoinColumn(name="Role$id", insertable=false ,updatable=false)
   @Column(name="Role$id")
   private Role role;
   

在这种情况下，我不知道持久性提供者必须如何行动。

在 Auth 实体中，您具有以下映射:

@Column(name="Uzer$id",updatable=false, insertable=false)
@Transient
private User user;

一方面，您告诉提供者不应保留该字段 (@Transient)，另一方面，您告诉它保留该字段，即 @列注释。因此，删除 @Column 注释或删除 @Transient 注释并正确映射属性(因为它指向另一个实体)。
