3.封装与使用

下面我以一个Java Bean为例，简单的对ormlite进行封装。以下是一个聊天消息的JavaBean 取名为ChatMsgEntity

我们不需要在类的前面添加注解，此时，该类映射的数据库表的名称就是类的名称。我们在需要入库的每一个java bean的Field上添加注解，表示这对应着数据库中的字段。对于自增加的主键，我们使用generatedId = true 
package edu.njupt.zhb.model;

import com.j256.ormlite.field.DatabaseField;

public class ChatMsgEntity {

在Activity中使用Dao对象

OrmSqliteDao<ChatMsgEntity> msgDao = new ChatMsgEntityDao(this);


然后就可以使用msgDao对ChatMsgEntity实体类进行“增删改查”的操作了。

软件简介
ORMLite是一个轻量级的Java对象关系映射持久层框架。支持包括 MySQL、Postgres、Microsoft SQL
Server、H2、Derby、HSQLDB和Sqlite等在内的数据库。提供灵活的QueryBuilder来构建复杂的数据查询。强大的抽象DAO类，只需5行代码便能够自动生成SQL来创建和删除数据库表格。
示例代码：
public class AccountApp {
public static void main(String[] args) throws Exception {
// this uses h2 by default but change to match your database
String databaseUrl = “jdbc:h2:mem:account”;
// create a connection source to our database
ConnectionSource connectionSource = new JdbcConnectionSource(databaseUrl);
// instantiate the dao
AccountDaoImpl accountDao = new AccountDaoImpl(connectionSource);
// if you need to create the ‘accounts’ table make this call
TableUtils.createTable(connectionSource, Account.class);
