ORMLite 数据库的使用--二次封装

ORMLite 数据库封装的使用

最近在做一个市政抄表机,录入用户水汽表数据到DB里面的,这个封装是同事封装的,封装的很好,文档也很详细,所以计入一下.方便下次使用.

推荐使用GreenDao3.2:https://mp.weixin.qq.com/s?__biz=MzAxMTI4MTkwNQ==&mid=2650821932&idx=1&sn=d26c09af7cbbfb1b0a95517bd78cc784&chksm=80b781b2b7c008a4a8dab45756e4d433b1c56e1c61762f98ee3b8a2b89a00756f82d6bb4d6b6&scene=0#rd

使用步骤：

##ORM使用基础工作：1、下载 ORMLite Jar首先去ORMLite官网下载jar包，对于Android为：ormlite-android-XXX.jar 和 ormlite-core-XXX.jar ；2、配置Bean类有了jar,我们在datamodule下把jar拷贝到libs下。然后新建一个包：com.sqlhelp专门用于存放项目中的Bean，首先新建一个Been.JavaBeen.java类作为所有数据结构的基类，涉及数据库相关的数据结构全部继承于此类首先在Been类上添加@DatabaseTable(tableName = "tb_been")，标明这是数据库中的一张表，表名为tb_been然后分别在属性上添加@DatabaseField(columnName = "name") ，columnName的值为该字段在数据中的列名@DatabaseField(generatedId = true) ，generatedId 表示id为主键且自动生成3、SQLiteOpenHelper原生的数据库操作，需要继承SQLiteOpenHelper，这里我们需要继承OrmLiteSqliteOpenHelper然后需要实现两个方法：onCreate(SQLiteDatabase database,ConnectionSource connectionSource)创建表，我们直接使用ormlite提供的TableUtils.createTable(connectionSource, User.class);进行创建~onUpgrade(SQLiteDatabase database, ConnectionSource connectionSource, int oldVersion, int newVersion)更新表，使用ormlite提供的TableUtils.dropTable(connectionSource, User.class, true);进行删除操作~删除完成后，别忘了，创建操作：onCreate(database, connectionSource);4、初始化：DatabaseHelper.getHelper(getApplicationContext());5、如果DatabaseHelper.getHelper(getApplicationContext())返回值为NULL，则表示数据库DB文件不存在或者路径配置不正确。正确的DB路径：内置SD卡下ncproject文件夹下的data文件夹readmachine.db6、如果DatabaseHelper.getHelper(getApplicationContext())返回值不为NULL，则表示初始化成功

假设你需要查找某张表,需要你自己去组织.详细的看如下:

第一步:以下三个方法每次执行数据库操作必须先初始化

/*** 变量初始化* @param clazz 对应的been的.class文件(你需要查找的那张表你自己所映射出来的bean文件)*/public Been(Context context,Class clazz)/*** 执行Dao变量的初始化方法*/public Dao getDao()/*** 执行QueryBuilder变量的初始化方法*/public void getQueryBuilder()

第二步:以下为SQL查询条件的一些设置(可选,多选,等等)

  /*** 设置是否排序* @param Coum    排序依据列* @param is_up_or_down  ture是升序，false降序*/public void Set_Order_By (String Coum,boolean is_up_or_down)/*** 设置是否去重复*/public void Set_Desc ()/*** 返回总条数* @return*/public long getAllNums()/***执行分页* @param limt 限制获取指定行数* @param offset 跳过指定的行数*/public void setPage(long limt,long offset)

第三步:以上为SQL组成where语句查询条件(可选,多选,等等)

/***SQL where语句初始化*/public Where<Object, Integer> getWhere()/*** 对应SQL：SELECT * FROM `xxxx` WHERE `id` = 2* @param map 里面存放的键值对key值必须和对应的Been里面的成员变量名保持一致，即要操作ciid,对应的KEY为"ciid"*             value值则余对应的变量类型保持一致* @return*/public Where<Object, Integer> SetBe_Equal_To(Map<String ,Object> map)/*** 对应SQL：SELECT * FROM `t_person` WHERE `id` < 2* @param map 里面存放的键值对key值必须和对应的Been里面的成员变量名保持一致，即要操作ciid,对应的KEY为"ciid"*             value值则余对应的变量类型保持一致* @return*/public Where<Object, Integer> SetLess_Than(Map<String ,Object> map)/*** 对应SQL：SELECT * FROM `t_person` WHERE `id` > 2* @param map 里面存放的键值对key值必须和对应的Been里面的成员变量名保持一致，即要操作ciid,对应的KEY为"ciid"*             value值则余对应的变量类型保持一致* @return*/public Where<Object, Integer> SetMore_Than(Map<String ,Object> map)/*** 对应SQL：SELECT * FROM `t_person` WHERE `id` >= 2* @param map 里面存放的键值对key值必须和对应的Been里面的成员变量名保持一致，即要操作ciid,对应的KEY为"ciid"*             value值则余对应的变量类型保持一致* @return*/public Where<Object, Integer> SetMore_Than_Or_Equal_To(Map<String ,Object> map)/*** 对应SQL：SELECT * FROM `t_person` WHERE `id` <= 2* @param map 里面存放的键值对key值必须和对应的Been里面的成员变量名保持一致，即要操作ciid,对应的KEY为"ciid"*             value值则余对应的变量类型保持一致* @return*/public Where<Object, Integer> SetLess_Than_Or_Equal_To(Map<String ,Object> map)/*** SELECT * FROM `t_person` WHERE `id` <> 2* @param map 里面存放的键值对key值必须和对应的Been里面的成员变量名保持一致，即要操作ciid,对应的KEY为"ciid"*             value值则余对应的变量类型保持一致* @return*/public Where<Object, Integer> SetNot_Equal_To(Map<String ,Object> map)/***SELECT * FROM `t_person` WHERE `LastName` LIKE 'A%'* @param map 里面存放的键值对key值必须和对应的Been里面的成员变量名保持一致，即要操作ciid,对应的KEY为"ciid"*             value值则余对应的变量类型保持一致* @return*/public Where<Object, Integer> SetLike_To(Map<String ,Object> map)/***获取指定范围内的结果* @param Colum  列名* @param low     范围开始* @param height  范围结束* @return*/public Where<Object, Integer> SetBetween_To(String Colum,Object low,Object height)

第四步:查找用户

   /***查找用户*/public List<Object> Search()

其他

/*** 增加一个记录*/getDao().create(Been);/*** 删除一条记录*/getDao().deleteById(id);/*** 更新一条记录*/getDao().update(Been);

给个简单的使用案例

现在我对水汽表进行数据的查询

if (mDataList == null || mDataList.size() == 0) {Map<String, Object> map = new HashMap<>();//gibfid    气表查询字段     mibfid 水表查询字段//base_user_info_w  db文件水表所映射的bean文件//初始化3步骤 bean  dao  getQueryBuilder(必须做)Been been = new Been(mContext, base_user_info_w.class);been.getDao();been.getQueryBuilder();//设置是否排序    更具表中micbh 字段排序been.Set_Order_By("micbh", true);(可略)//一次取800条(不足的情况返回最大的数值)been.setPage(800, 0);   (可以不分页更具需求更爱)//初始化  where    (必须做)been.getWhere();//map  存查询条件     (必须做)map.put("mibfid", mContext);been.SetBe_Equal_To(map, "And");  (必须做)//开始搜索         (必须做)mDataList = been.Search();} else {Been been = new Been(mContext, base_user_info_g.class);been.getDao();been.getQueryBuilder();been.Set_Order_By("gicbh", true);been.setPage(800, 0);been.getWhere();map.put("gibfid", mValue);been.SetBe_Equal_To(map, "And");mDataList = been.Search();}}

ORMLite 数据库的使用--二次封装

ORMLite 数据库封装的使用

最近在做一个市政抄表机,录入用户水汽表数据到DB里面的,这个封装是同事封装的,封装的很好,文档也很详细,所以计入一下.方便下次使用.

推荐使用GreenDao3.2:https://mp.weixin.qq.com/s?__biz=MzAxMTI4MTkwNQ==&mid=2650821932&idx=1&sn=d26c09af7cbbfb1b0a95517bd78cc784&chksm=80b781b2b7c008a4a8dab45756e4d433b1c56e1c61762f98ee3b8a2b89a00756f82d6bb4d6b6&scene=0#rd

使用步骤：

假设你需要查找某张表,需要你自己去组织.详细的看如下:

第一步:以下三个方法每次执行数据库操作必须先初始化

第二步:以下为SQL查询条件的一些设置(可选,多选,等等)

第三步:以上为SQL组成where语句查询条件(可选,多选,等等)

第四步:查找用户

其他

给个简单的使用案例

现在我对水汽表进行数据的查询

下面贴出用的的java类

Been

DatabaseHelper

UserDao

这个是数据库db表中映射的bean (水表)
