simplenamemapper.java

使用annotation封装的jdbc

package cn.cja.dao;

import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.util.Collection;
import java.util.Map;

import net.sf.cglib.beans.BeanMap;

public class SimpleNameMapper implements IORMapper {

	public Object orm(Class<?> clazz, ResultSet rs) {
		Object entity = null;
		try {
			ResultSetMetaData metaData = rs.getMetaData();
			int size = metaData.getColumnCount();
			entity = clazz.newInstance();
			Map map = BeanMap.create(entity);
			for (int i = 1; i <= size; i++) {
				map.put(metaData.getColumnLabel(i), rs.getObject(i));
			}
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InstantiationException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalAccessException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return entity;
	}
