来看一个测试应用,对象是User：

@BeanTableName(name="z_user")public class User extends ThinObject {@PrimaryString uid ;String uname;String rid;public User(String userid, String username) {super();this.uid = userid;this.uname = username;}public User() {}@Overridepublic String toString() {return "(userid:"+uid+", username:"+uname+")";}              //setter and getter}

 测试类：

 

 

public class TestUser extends TestCase {static {new TryThinContext("zero");ThinContext.setDefaultSchema("zero");}public void testUpdate() throws SQLException{User user = new User("wanghh","王海洪");user.obtainMe();user.setUname("海洪");user.updateMemory("uname");System.out.println(user.rid);}public void testAdd() throws SQLException{User user = new User("thinery","王海洪");user.setRid("admin");user.remember();}public void testDelete() throws SQLException{User user = new User();user.setUid("thinery");user.forget();}public void testQuery() throws SQLException{User user = new User();List<Object> users = user.associate(SQLCriterion.get("rid", Operator.EQ, "marketing"));System.out.println(users);}@Overrideprotected void tearDown() throws Exception {ThinContext.getThinContext().cleanHoldConection();}}

 在看一个扩展的对象

 

public class Group  extends ThinObject{@Overridepublic List associate(Object... params) {//获取自定义SQLString sql = sqls.getProperty("subGroupUser");List<Map<String,Object>>  datas =null;try {QueryBeanTable qbt = ThinContext.ctx.getQueryBeanTable("subGroupUser");qbt.setQuerySQL(sql);qbt.setParameters(params);datas =  qbt.query();} catch (Exception e) {e.printStackTrace();}return datas;}/** * 给组里添加新用户 * @param users */public void add(User... users){//to write by yourself}}

 

 

如果全部这样的方式编写，可以少写不少DAO，service，甚至全部不写。一切都在对象模型里了。这种对象模型一旦建立完成。相关系统就可以相互复用。就像一个车轮子可以供多个车型使用。
