您好，我试图解决，但我没有解决它

像这样得到异常

org.springframework.orm.hibernate3.HibernateSystemException: a different object with the same identifier value was already associated with the session:

[com.omnypay.dao.bo.CloudSvrUsersProfile#284]; nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.omnypay.dao.bo.CloudSvrUsersProfile#284]

原因：

org.hibernate.NonUniqueObjectException: a different object with the same identifier value was 
already associated with the session:

我的用户类别是

@Entity
@Table(name="CLOUD_SVR_USERS")
@NamedQuery(name="CloudSvrUser.findAll", query="SELECT c FROM CloudSvrUser c")
public class CloudSvrUser implements Serializable {

    @Id
        @GeneratedValue
        @Column(name="USER_ID")
        private long userId;

    it has some column and the oneto one relation like

    @OneToOne(mappedBy="user",fetch=FetchType.LAZY,cascade=CascadeType.ALL) 
    private CloudSvrUsersProfile usersProfile;

    and getters&setters

我的个人资料课程是

@Entity
@Table(name="CLOUD_SVR_USERS_PROFILE1")
@NamedQuery(name="CloudSvrUsersProfile.findAll", query="SELECT c FROM CloudSvrUsersProfile c")
public class CloudSvrUsersProfile implements Serializable {

private static final long serialVersionUID = 1L;

    @Id
    @Column(name="USER_ID",nullable=false)
    @GeneratedValue(generator="gen")
    @GenericGenerator(name="gen", strategy="foreign", parameters=@Parameter(name="property", value="user"))

    private Long usersProfileId;
      //columns and

@OneToOne
    @PrimaryKeyJoinColumn
    private CloudSvrUser user;


    @Transient
    private String emailId;

服务实现类是

@Transactional
    public void UpdateUserProfile(CloudSvrUsersProfile userProf) throws BusinessException
    {
        try{
        CloudSvrUser dbUser = getUser(userProf);

        //CloudSvrUsersProfile dbUserProfile = dbUser.getUsersProfile();
        //CloudSvrUsersProfile updatedProf=userProf.getUsersProfile();
    if(dbUser != null){

            //CloudSvrUsersProfile newUserInfoList  = new CloudSvrUsersProfile();
            //CloudSvrUsersProfile newUserInfoList  = CloudSvrUsersProfile();
            CloudSvrUsersProfile updatedProf = new CloudSvrUsersProfile();

            updatedProf.setFirstName(userProf.getFirstName());
            updatedProf.setLastName(userProf.getLastName());
            updatedProf.setAddress1(userProf.getAddress1());
            updatedProf.setAddress2(userProf.getAddress2());
            updatedProf.setAddress3(userProf.getAddress3());
            updatedProf.setZipCode(userProf.getZipCode());
            updatedProf.setState(userProf.getState());
            //
            updatedProf.setStatus(Long.parseLong("1"));
            updatedProf.setCreatedBy(Long.parseLong("1"));
            updatedProf.setCreatedDate(new Timestamp(System.currentTimeMillis()));



            //updatedProf.setEmialId(userProf.getEmialId());
            dbUser.setEmailId(userProf.getEmailId() );
            dbUser.setUsersProfile(updatedProf);
            updatedProf.setUser(dbUser);

            updateuser(dbUser);  


    }
        }
    catch(DaoException daoException) {

        throw new BusinessException(daoException.getMessage());
    }   

    }

对于第一个请求，它向 db 输入数据，但对于第二个请求，当我更改某些值并尝试从我的 url 中访问 db 时，它给出了上述异常

请帮帮我

【问题讨论】：

您的服务等的邮政编码
请粘贴导致此问题的代码？
try {// super.getHibernateTemplate().save(user); //super.getHibernateTemplate().saveOrUpdate(user); //super.getHibernateTemplate().update(user); //this.userDao.updateUser(dbUser); } catch(DataAccessException accessException){ throw new DaoException("发生内部数据库错误。"); }
这是我的 dao impl 类，我还有 2 个类 user 和 profile 类，我与 userprofile 有一对一的关系
@smita 不要将代码添加到 cmets.. instate 编辑您的问题并添加 DAO 和服务类的代码

标签： java spring hibernate session spring-mvc

【解决方案1】：

删除

cascade=CascadeType.ALL

来自您的用户类。
