请问Entity可以转换成Record吗？

主要的功能是：
我想在前台查询条件以对象的形式传入后台之后，后台将这个对象反射获取属性和值，根据类型自动生成Cnd对象，省得写一大堆的判断。

我现在的做法是（代码如下）：

问题是：我不想让外面传入Record，想传入对象，请问Entity可以转换成Record吗

public static  Cnd getCndByEntity(Class clazz, Record rs) throws SQLException {
		try {
			Cnd cnd=Cnd.NEW();
			Cnd.where(new Static("1=1"));
			Object obj = clazz.newInstance();
			Field[] fields = clazz.getDeclaredFields();
			int index = 0;

			Set<String> set=((Record) rs).getColumnNames();
			 Iterator iterator= set.iterator();
			 while(iterator.hasNext()){//遍历  
				String columnName =  iterator.next().toString();
				for (Field field : fields) {
					String name = field.getName();
					String newColumnName = columnName;
					while (((index = newColumnName.indexOf("_")) > 0) && index < newColumnName.length()) { // 两个条件排除了下划线是第一个和最后一个字符的可能性
						newColumnName = newColumnName.substring(0, index)
								+ Character.toUpperCase(newColumnName.charAt(index + 1))
								+ newColumnName.substring(index + 2);
					}
					if (name.equals(newColumnName)) { // 如果属性相同
						Class clType = field.getType();
						String typeName = clType.getName();
						newColumnName = "set" + Character.toUpperCase(newColumnName.charAt(0))
								+ newColumnName.substring(1);
						if (typeName.equals("int")) {
							int value = rs.getInt(columnName);
							Method method = clazz.getMethod(newColumnName, Integer.class);
							method.invoke(obj, value);
							cnd.and(name,"=",value);

						} else if (typeName.equals("double")) {
