hibernate3学习笔记(十四)｜Blob、Clob[Java编程]

在Hibernate中,可以直接对Blob、Clob作映射.

DDL以下:

1.CREATE TABLE user (
2.    id INT(11) NOT NULL auto_increment PRIMARY KEY,
3.    name VARCHAR(100) NOT NULL default '',
4.    age INT,
5.    photo BLOB,
6.    resume TEXT
7.);

注意:由于BLOB字段大小不可预计,有时需求增大BLOB字段的大小,可在数据库中改用MEDIUMBLOB乃至LONGBLOB.

User.java

1.package com.hb3.pack_07.model;
2.
3.import java.sql.Blob;
4.import java.sql.Clob;
5.
6.public class User {
7.
8.    private Integer id;
9.    private String name;
10.    private Integer age;
11.    private Blob photo;
12.    private Clob resume;
13.
14.    public User() {
15.    }
16.
17.    public Integer getId() {
18.        return id;
19.    }
20.    public void setId(Integer id) {
21.        this.id = id;
22.    }
23.    public String getName() {
24.        return name;
25.    }
26.    public void setName(String name) {
27.        this.name = name;
28.    }
29.    public Integer getAge() {
30.        return age;
31.    }
32.    public void setAge(Integer age) {
33.        this.age = age;
34.    }
35.    public Blob getPhoto() {
36.        return photo;
37.    }
38.    public void setPhoto(Blob photo) {
39.        this.photo = photo;
40.    }
41.    public Clob getResume() {
42.        return resume;
43.    }
44.    public void setResume(Clob resume) {
45.        this.resume = resume;
46.    }
47.}
