将JSONOject或者一个实体类中的属性赋值到另一个实体类中

public Object addPropertyVale(JSONObject data, Object entity)
			throws IllegalArgumentException, IllegalAccessException {

		Field fields[] = entity.getClass().getDeclaredFields();
		for (Map.Entry
 
   entry : data.entrySet()) {
			for (int i = 0; i < fields.length; i++) {
				fields[i].setAccessible(true);

				if (fields[i].getName().equals(entry.getKey())) {// json字段key和对象实体属性名相同
					// 将value赋值给属性
					if (fields[i].getGenericType().getTypeName().equals("java.lang.String")) {

						fields[i].set(entity, data.getString(entry.getKey()));
					}
					if (fields[i].getGenericType().getTypeName().equals("java.lang.Integer")) {
						fields[i].set(entity, data.getInteger(entry.getKey()));
					}
					if (fields[i].getGenericType().getTypeName().equals("java.lang.Long")) {
						fields[i].set(entity, data.getLong(entry.getKey()));
					}
					if (fields[i].getGenericType().getTypeName().equals("int")) {
						fields[i].set(entity, data.getInteger(entry.getKey()));
