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;

/**

* File: UserInfo.java

* Author: admin

* Version: 1.0

* Date: 2014/08/13

* Modify:

@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"?>

);
