有没有人内置购买后，恢复成功的代码（in-app purchases)已解决

一句话描述,使用AHibernate框架进行sqlite数据库操作您将从重复性劳动中解脱出来.

(一)支持功能:
1.自动建表,支持属性来自继承类:可根据注解自动完成建表,并且对于继承类中的注解字段也支持自动建表.
2.自动支持增删改,增改支持对象化操作:增删改是数据库操作的最基本单元,不用重复写这些增删改的代码,并且添加和更新支持类似于hibernate中的对象化操作.
3.查询方式灵活:支持android框架提供的方式,也支持原生sql方式.
4.查询结果对象化:对于查询结果可自动包装为实体对象,类似于hibernate框架.
5.查询结果灵活:查询结果支持对象化,也支持结果为List>形式,这个方法在实际项目中很实用,且效率更好些.
6.日志较详细:因为android开发不支持热部署调试,运行报错时可根据日志来定位错误,这样可以减少运行Android的次数.

(二)不足之处:
1.id暂时只支持int类型,不支持uuid,在sqlite中不建议用uuid.
2.现在每个方法都自己开启和关闭事务,暂时还不支持在一个事务中做多个操作然后统一提交事务.

(三)作者寄语:
昔日有JavaScript借Java发展,今日也希望AHibernate借Hibernate之名发展.希望这个项目以后会成为开源社区的重要一员,更希望这个项目能给所有Android开发者带便利.欢迎访问我的博客:http://blog.csdn.net/lk_blog,这里有这个框架的使用范例和源码,希望朋友们多多交流完善这个框架,共同推动中国开源事业的发展,AHibernate期待与您共创美好未来!!!
框架源代码见下一篇博客:http://blog.csdn.net/lk_blog/article/details/7456125 ,源代码供大家交流使用,欢迎朋友们对代码提供宝贵意见.

先看一个使用例子吧,看看您是否满意:

        teacherDao.execSql("insert into t_teacher(name,age) values('米教授',50)", null);  
  
    }  
}  

使用AHibernate步骤:
步骤1.引入AHibernate-1.0.jar  下载地址: http://download.csdn.net/detail/lk_blog/4222048 解压后有源码和jar包,这个jar体积非常小,仅有十几K,对您的程序整体大小不会产生影响哦.

步骤2.建实体类

Person.java:

[java] view plaincopy
package com.tgb.lk.demo.model;  
import com.tgb.lk.ahibernate.annotation.Column;  
import com.tgb.lk.ahibernate.annotation.Id;  
//此处没有加Table属性,它是其他类的基类,本类中用@Column注解的字段在子类中同样会被创建到表中.  
public class Person {  
    @Id  
    @Column(name = "id")  
    private int id; // 主键,int类型,数据库建表时此字段会设为自增长  
  
    @Column(name = "name", length = 20)  
    private String name; // 名字长度一般不会超过20个字符吧,length=20数据字段的长度是20  
  
    @Column(name = "age", type = "INTEGER")  
    private int age; // 年龄一般是数值,用type = "INTEGER"规范一下吧.  
  
    // //假设您开始时没有此属性,程序开发中才想到此属性,去掉代码注释试试吧,数据库增删改查不用修改任何代码哦.  
    // @Column(name = "sex")  
    // private String sex;  
  
    // 有些字段您可能不希望保存到数据库中,不用@Column注释就不会映射到数据库.  
    private String noSaveFild;  
  
    //get和set方法.  
    //....  
  
    @Override  
    public String toString() {  
        return "id=" + id + ", name=" + name + ",age=" + age;  
    }  
}  
  
Teacher.java
[java] view plaincopy
package com.tgb.lk.demo.model;  
import com.tgb.lk.ahibernate.annotation.Column;  
import com.tgb.lk.ahibernate.annotation.Table;  
  
//自动生成的建表语句:  
//crate table [t_teacher]: CREATE TABLE t_teacher (id INTEGER primary key autoincrement, title TEXT, name TEXT(20), age INTEGER )  
  
@Table(name = "t_teacher")  
public class Teacher extends Person {  
    @Column(name = "title")  
    private String title;// 职称  
  
    //get和set方法.  
    //....  
  
    @Override  
    public String toString() {  
        return "Teacher [" + super.toString() + ",title=" + title + "]";  
    }  
}  
  
Student.java
[java] view plaincopy
package com.tgb.lk.demo.model;  
  
import com.tgb.lk.ahibernate.annotation.Column;  
import com.tgb.lk.ahibernate.annotation.Table;  
  
//自动生成的建表语句:  
//CREATE TABLE t_student (id INTEGER primary key autoincrement, classes TEXT, teacher_id INTEGER, name TEXT(20), age INTEGER )  
  
@Table(name = "t_student")  
public class Student extends Person {  
  
    @Column(name = "teacher_id")  
    private int teacherId;// 班主任id  
  
    @Column(name = "classes")  
    private String classes;// 班级  
  
    //get和set方法  
    //...  
  
    @Override  
    public String toString() {  
        return "Student [" + super.toString() + ",teacherId=" + teacherId  
                + ", classes=" + classes + "]";  
    }  
}  
  
步骤3:
 DBHelper.java

[java] view plaincopy
package com.tgb.lk.demo.util;  
  
import com.tgb.lk.ahibernate.util.MyDBHelper;  
import com.tgb.lk.demo.model.Student;  
import com.tgb.lk.demo.model.Teacher;  
import android.content.Context;  
  
public class DBHelper extends MyDBHelper {  
    private static final String DBNAME = "school.db";// 数据库名  
    private static final int DBVERSION = 1;  
    private static final Class[] clazz = { Teacher.class, Student.class };// 要初始化的表  
  
    public DBHelper(Context context) {  
        super(context, DBNAME, null, DBVERSION, clazz);  
    }  
  
}  
  

步骤4:
StudentDaoImpl.java

[java] view plaincopy
package com.tgb.lk.demo.dao.impl;  
  
import com.tgb.lk.ahibernate.dao.impl.BaseDaoImpl;  
import com.tgb.lk.demo.model.Student;  
import com.tgb.lk.demo.util.DBHelper;  
import android.content.Context;  
  
//如果您是J2EE高手一定希望支持接口吧,按下面的写法即可:  
//写一个接口:public interface StudentDao extends BaseDao {}  
//实现接口: public class StudentDaoImpl extends BaseDaoImpl implements StudentDao  
public class StudentDaoImpl extends BaseDaoImpl {  
    public StudentDaoImpl(Context context) {  
        super(new DBHelper(context));  
    }  
}  
  
TeacherDaoImpl.java
[java] view plaincopy
package com.tgb.lk.demo.dao.impl;  
  
import com.tgb.lk.ahibernate.dao.impl.BaseDaoImpl;  
import com.tgb.lk.demo.model.Teacher;  
import com.tgb.lk.demo.util.DBHelper;  
import android.content.Context;  
  
public class TeacherDaoImpl extends BaseDaoImpl {  
    public TeacherDaoImpl(Context context) {  
        super(new DBHelper(context));  
    }  
}  
  

步骤5: 
运行文章开始处的例子试试吧.

程序运行时会根据注解自动建表,增删改查的数据库访问层不用写其他的代码就能直接使用.
