Hibernate3.X实现基于CLOB字段类型的注解方式：

一：Hibernate3.X实现基于CLOB字段类型的注解方式的例子：下面直接上代码：

二：UserInfo.java

package cn.gov.csrc.cms.model;

import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Lob;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;

import oracle.sql.CLOB;

@Entity
@Table(name = "tb_cms_user")
public class UserInfo {

  private Integer userId;// ID

  private String userName;// 登录名

  private String passWd;// 登录密码

  private String realName;// 用户姓名

  private String phone;// 电话

  private String dept;// 部门

  private String post;// 岗位
  
  private CLOB fieldNames;// 存放xml文本文件的字段

  @Id
  @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQ_STORE")
  @SequenceGenerator(name = "SEQ_STORE", sequenceName = "USER_SEQ", allocationSize = 1)
  public Integer getUserId() {
    return userId;
  }

  public void setUserId(Integer userId) {
    this.userId = userId;
  }

  @Column(name = "USERNAME", nullable = false, length = 30)
  public String getUserName() {
    return userName;
  }

  public void setUserName(String userName) {
    this.userName = userName;
  }

  @Column(name = "PASSWD", nullable = false, length = 100)
  public String getPassWd() {
    return passWd;
  }

  public void setPassWd(String passWd) {
    this.passWd = passWd;
  }

  @Column(name = "REALNAME", length = 10)
  public String getRealName() {
    return realName;
  }

  public void setRealName(String realName) {
    this.realName = realName;
  }

  @Column(name = "PHONE", length = 15)
  public String getPhone() {
    return phone;
  }

  public void setPhone(String phone) {
    this.phone = phone;
  }

  @Column(name = "DEPT", length = 10)
  public String getDept() {
    return dept;
  }

  public void setDept(String dept) {
    this.dept = dept;
  }

  @Column(name = "POST", length = 10)
  public String getPost() {
    return post;
  }

  public void setPost(String post) {
    this.post = post;
  }

  @Lob 
  @Basic(fetch = FetchType.EAGER) 
  @Column(name="FIELDNAMES", columnDefinition="CLOB", nullable=true)
  public CLOB getFieldNames() {
    return fieldNames;
  }

  public void setFieldNames(CLOB fieldNames) {
    this.fieldNames = fieldNames;
  }
  
  
}

三：Oracle中直接通过sql插入CLOB字段类型的数据：

/* Formatted on 2014/8/19 15:45:29 (QP5 v5.115.810.9015) */
INSERT INTO TB_CMS_USER (
                            USERID,
                            DEPT,
                            PASSWD,
                            PHONE,
                            POST,
                            REALNAME,
                            USERNAME,
                            FIELDNAMES
           )
  VALUES   (
               1,
               '开发支持部',
               '123456789',
               '18611966723',
               'Java工程师',
               '工程师',
               'zhaoxinguo',
               '<?xml version="1.0" encoding="UTF-8"?>

           );
