从两个tomcat实例更新相同的DB时获取StaleStateException（要更新的行是不同的）

Question

尝试使用来自两个不同的tomcat实例的hibernate来更新表的两个不同的行时获得以下异常。获得的所有来源都提示并发更新问题，但此处仍有两个不同的行正在更新获得异常。查看版本控制问题，因为两个不同的会话试图保持同一个类。

Class有以下字段：

    @Entity
    @Table(name="yt_platinum_user")
    public class PlatinumUserInfo {

        @Id
        @GeneratedValue(strategy=GenerationType.AUTO)
        @Column(name="id_platinum_user")
        private Long idPlatinumUser;

        @Column(name="first_name")
        private String first_name;

        @Column(name="last_name")
        private String last_name;

        @Column(name="email")
        private String email;

        @Column(name="phone")
        private String phone;

        @Column(name="title")
        private String title;

        @Column(name="link_rewrite")
        private String link_rewrite;

        @Column(name="is_fresco_updated")
        private int is_fresco_updated;

        @Column(name="is_infinity_updated")
        private int is_infinity_updated;

        @Column(name="is_mo_updated")
        private int is_mo_updated;

        @Temporal(TemporalType.TIMESTAMP)
        @Column(name="insert_date")
            private Date insertDateTime=new Date();

        @Version
        @Temporal(TemporalType.TIMESTAMP)
        @Column(name="update_date")
            private Date updateDateTime=new Date();
}

更新DAO类的功能：

public ResponseEntity<Object> updateData(String title,String first_name,String last_name,String link_rewrite)
    {
        try
        {
            List<PlatinumUserInfo> ptInfoList=hibernateTemplate.find("from PlatinumUserInfo where link_rewrite =? ", link_rewrite);
            if(!(ptInfoList==null||ptInfoList.isEmpty()))
            {

                ptInfoList.get(0).setFirst_name(first_name);
                ptInfoList.get(0).setLast_name(last_name);
                ptInfoList.get(0).setTitle(title);
                hibernateTemplate.update(ptInfoList.get(0));
                ResponseEntity<Object> resp=new ResponseEntity<Object>(ptInfoList.get(0), HttpStatus.OK);
                return resp;
            }
            else
            {
                logger.error("No applicable record found for ciphertext :"+link_rewrite);
                return new ResponseEntity<Object>(new CustomMessage("No applicable record found ! "), HttpStatus.OK);
            }
        }
        catch(Exception e)
        {
            logger.error("Exception occurred while getting response :"+e);
            e.printStackTrace();

            return new ResponseEntity<Object>(new CustomMessage("Error occurred while getting response for "+link_rewrite), HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }
