私は2つのドメインを持っています - ユーザーとカタログ... 1人のユーザーが多数のカタログを持つことができます。 は、これは私のUser.javaファイルですcom.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException：不明な列 '....'

この1つは私のCatalog.javaファイル
package com.egs.account.model;
import javax.persistence.*;
import java.util.Date;
@Entity
@Table(name = "catalog")
public class Catalog {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String link;
private String comment;
private Date insertDate;
@ManyToOne(optional = false)
@JoinColumn(name = "USER_ID")
private User user;
@Lob @Basic(fetch = FetchType.LAZY)
@Column(name="content", nullable=false)
private byte[] content;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getLink() { return link; }
public void setLink(String link) { this.link = link; }
public String getComment() { return comment; }
public void setComment(String comment) { this.comment = comment; }
public Date getInsertDate() { return insertDate; }
public void setInsertDate(Date insertDate) { this.insertDate = insertDate; }
public User getUser() { return user;}
public void setUser(User user) { this.user = user; }
public byte[] getContent() { return content; }
public void setContent(byte[] content) { this.content = content; }
}
であるこの私が私のリポジトリ、サービス・クラスで を使用するものを拡張し、そこから私のabstractDaoクラスがあります。ここで私はそのエラーここ

をあるの取得と思うによる先ののgetSession（）メソッドを呼び出して、私は私のユーザードメインを保持しようとしたとき、私はそのような例外を取得します。
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.HibernateException: No Session found for current thread
誰も私にこの例外の理由を教えてもらえますか？
