ibatis的增删改查 一对一、一对多等

项目需要，需要用ibatis，我花了一天时间学习，一天时间整理，希望能和刚入门的ibatis朋友，一起分享.....

public class IbatisDemo {
	public static void main(String[] args) throws IOException,SQLException{
//		读取配置文件
		Reader reader = Resources.getResourceAsReader("SqlMapConfig.xml");
		SqlMapClient sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader);
//		单表的增删改查
//		①、查询表集合
		/*List<LockBean> lockList = (List<LockBean>)sqlMap.queryForList("lockNameSpace.getLockList");
		for(LockBean lb : lockList){
			System.out.println(
					lb.getId()+" "+lb.getLockName()+" "+lb.getLockFactory() 
			);
		}*/
//		②、查询表对象 by id
		/*LockBean lb = (LockBean)sqlMap.queryForObject("lockNameSpace.getLockObjectById",new Long(1));
		System.out.println(
				lb.getId()+" "+lb.getLockName()+" "+lb.getLockFactory()
		);*/
//		③、查询表对象 by like
		/*List<LockBean> lockList = (List<LockBean>)sqlMap.queryForList("lockNameSpace.getLockObjectByLike",new String("南京"));
		for(LockBean lb : lockList){
			System.out.println(
					lb.getId()+" "+lb.getLockName()+" "+lb.getLockFactory() 
			);
		}*/
//		④、查询表对象 动态组合查询
//		test 前台http 获取属性值
	/*	LockBean lb = new LockBean();
		lb.setLockFactory("南京");
		lb.setLockType(new Integer(12));
		List<LockBean> lockList = (List<LockBean>)sqlMap.queryForList
		("lockNameSpace.getLockListByDynamic",lb);
		for(LockBean lock : lockList){
			System.out.println(
					lock.getId()+" "+lock.getLockName()+" "+lock.getLockFactory() 
			);
		}*/
//		⑤、多表查询 - 一对一 关联查询 ... (所谓“n+1”Select问题)
		/*List<LockBean> lockList = (List<LockBean>)sqlMap.queryForList
		("lockNameSpace.getLockList");
		for(LockBean lock : lockList){
			System.out.println(
					lock.getId()+" "+lock.getLockName()+" "+lock.getLockInfo().getLockMoney()
			);
		}*/
//		⑥、多表查询 - 一对一 （解决所谓“n+1”Select问题）
		/*List<LockBean> lockList = (List<LockBean>)sqlMap.queryForList
		("lockNameSpace.getLockListOneToOne");
		for(LockBean lock : lockList){
			System.out.println(
					lock.getId()+" "+lock.getLockName()+" "+lock.getLockInfo().getLockMoney()
			);
		}*/
//		7、 多表查询 一对多(基本解决，有个bug.....)
		/*List<LockBean> lockList = (List<LockBean>)sqlMap.queryForList
		("lockNameSpace.getLockList");
		System.out.println("size = "+lockList.size());
		for(int i=0;i<lockList.size();i++)
		{
			LockBean lb = lockList.get(i);
			System.out.println(lb.getId()+" - ");
			for(int j=0;j<lb.getKeyList().size();j++){
				KeyBean kb = lb.getKeyList().get(j);
				System.out.println(kb.getLockId()+" "+kb.getId()+" "+kb.getKeyName());
			}
		}*/
//		8、插入操作 insert
		/*LockBean lb = new LockBean();
		lb.setLockName("lockName");
		lb.setLockFactory("lockFactory");
		lb.setLockColor("lockColor");
		lb.setLockType(new Integer(44));
		sqlMap.insert("lockNameSpace.insertLock",lb);
		System.out.println("insert success .... ");*/
		
//		9、批量插入操作 insert
		/*List<LockBean> lbList = new ArrayList<LockBean>();
		for(int i=0;i<5;i++){
			LockBean lb = new LockBean();
			lb.setLockName("lockName"+i);
			lb.setLockFactory("lockFactory"+i);
			lb.setLockColor("lockColor"+i);
			lb.setLockType(new Integer(44)+i);
			lbList.add(lb);
		}*/
//		结合spring批量处理
		/*SqlMapClientCallback callback = new SqlMapClientCallback() {
            public Object doInSqlMapClient(SqlMapExecutor executor) throws SQLException {    
                executor.startBatch();
                for (T tObject : memberList) {               
                    executor.insert(statement, tObject); // statement在*MapSql.xml一条语句的id    
                }            
                executor.executeBatch();           
                return null;
            }
        };*/
//		ibatis 批量插入 - 删除跟新类似
		/*sqlMap.startTransaction();
		for(int i=0;i<lbList.size();i++){
			sqlMap.insert("lockNameSpace.batchInsertLock",lbList.get(i));
		}
		sqlMap.executeBatch();
		sqlMap.commitTransaction();
		sqlMap.endTransaction();
		System.out.println("批量插入完成................");*/
		
//		10、 删除操作 delete
		/*sqlMap.delete("lockNameSpace.deleteLock",100);*/
		
//		11、批量删除
		/*sqlMap.startTransaction();
		for(int i=51;i<100;i++){
			sqlMap.delete("lockNameSpace.deleteLock",i);
		}
		sqlMap.executeBatch();
		sqlMap.commitTransaction();
		sqlMap.endTransaction();
		System.out.println("批量删除完成................");*/
		
//		12、更新操作 update ..
		/*LockBean lb = new LockBean();
		lb.setLockName("updatelockName");
		lb.setLockColor("upColor");
		lb.setId(50);
		sqlMap.update("lockNameSpace.updateLock",lb);
		System.out.println("更新完成。。。。。");*/
//		13、批量更新
		/*List<LockBean> lbList = new ArrayList<LockBean>();
		for(int i=50;i<60;i++){
			LockBean lb = new LockBean();
			lb.setLockName("lockName"+i);
			lb.setLockFactory("lockFactory"+i);
			lb.setLockColor("Color"+i);
			lb.setLockType(new Integer(44)+i);
			lb.setId(i);
			lbList.add(lb);
		}
		
		sqlMap.startTransaction();
		for(int i=0;i<lbList.size();i++){
			sqlMap.update("lockNameSpace.updateLock",lbList.get(i));
		}
		sqlMap.executeBatch();
		sqlMap.commitTransaction();
		sqlMap.endTransaction();
		System.out.println("批量更新完成................");*/
