cube-orm

此项目是为Android简单封装的SQLite数据库ORM, 实现自动建表和自动更新升级,实现基本的单表CRUD,提高数据库开发效率。

使用方法

Android Studio引用方式:

compile 'com.github.supersanders:cube-orm:3.1@aar'

混淆配置:

-keep public class * extends com.sanders.db.IDColumn

约定:

所有的实体都要继承IDColumn.java类,并遵守以下命名规范:

表名称和Java类名称对应表:

表名称 Java类名 备注
table_name TableName 表名称必须以小写字母开始,单词之间用“_”下划线分开(当然也可以全部小写不分开)

表字段名称和Java类属性字段名称对应表:

表字段 Java字段 备注
field_name fieldName 表字段名称必须以小写字母开始,单词之间用“_”下划线分开(当然也可以全部小写不分开)。按照Java驼峰命名规范命名Java字段属性名称

数据库创建方式:

创建方式 说明
系统创建数据库 支持自动建表,自动升级。如果使用自动升级,若表字段类型有变则会重新创建新表并备份旧表为 表名_oldVersion,这需要手动将数据导入新表。
外部数据库 不支持自动建表和升级。另外主键名称必须是primary_key
系统创建表
//使用DBContext自动化创建表,每个表对应一个继承IDColumn.java类的POJO实体
DBContext dbContext = new DBContext("数据库名称", 数据库名称, new OnDBUpgrade() {
        @Override
        public boolean onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        	//return false 自己处理升级,return true 自动处理
            return false;
        }
    });
dbContext.addTableBean(TableModel.class).addTableBean(TableBean.class);
DBProxy db = dbContext.buildDBProxy(this);

//使用DBContextUse创建数据库
DBContextUse dbContextUse = new DBContextUse("数据库名称", 数据库版本, OnDBUpgrade);
dbContextUse.addSql(create table sql).addSql(create table sql);
DBProxy db = dbContextUse.buildDBProxy(getApplicationContext());
设置外部数据库,主键名称必须是primary_key
DBFile dbFile = new DBFile(file path or File);
DBProxy db = dbFile.buildDBProxy();
DBProxy.java类包涵了所有数据库操作
