本文介绍了一种将JavaBean对象转换为Record对象以及从Record对象转换回JavaBean对象的方法。通过反射机制，该方法能够自动匹配字段并进行转换，适用于数据传输和存储场景。

JavaBean转Record方法

public static Record javaBeanToRecord(Object obj) throws IllegalArgumentException, IllegalAccessException{
		if(obj != null){
			Record record = new Record();
			Class clazz = obj.getClass();
			Field[] fields = clazz.getDeclaredFields();
			for(int i=0; i<fields.length; i++){
				Field field = fields[i];
				if(!field.isAccessible())  {
					field.setAccessible(true);
				}
				System.out.println(field.getName()+" : "+field.get(obj));
				record.set(field.getName(), field.get(obj));
			}
			return record;
		}
		return null;
	}

Record转JavaBean方法

public static Object recrodToJavaBean(Record record, Class clazz) throws InstantiationException, IllegalAccessException, NoSuchFieldException, SecurityException{
		if(record != null){
			Object obj = clazz.newInstance();
			String[] columns = record.getColumnNames();
			for(String col: columns){
				Field field = clazz.getDeclaredField(col);
				if(field != null){
					if(!field.isAccessible()){
						field.setAccessible(true);
					}
					field.set(obj, record.getObject(col));
				}
			}
			return obj;
		}
		return null;
	}
