使用build pattern对代码进行重构

CardUpgradeDao.java

public class CardUpgradeDao extends ShopBaseService {
  // 重构之前得代码
	public void insert(Integer userId,MemberCardRecord oldCard, MemberCardRecord newCard) {
		CardUpgradeRecord re = db().newRecord(CARD_UPGRADE);
		String operation = "Admin option";
		re.setUserId(userId);
		re.setOldCardId(oldCard.getId());
		re.setNewCardId(newCard.getId());
		re.setOldGrade(oldCard.getGrade());
		re.setNewGrade(newCard.getGrade());
		re.setOldCardName(oldCard.getCardName());
		re.setNewCardName(newCard.getCardName());
		re.setGradeCondition(newCard.getGradeCondition());
		re.setOperate(operation);
		re.insert();
	}
	 // 之后的代码
  public void insert(Integer userId,MemberCardRecord oldCard, MemberCardRecord newCard) {
		String operate = "Admin option";
		CardUpgradeRecordBuilder builder = CardUpgradeRecordBuilder.create(db().newRecord(CARD_UPGRADE));
		
		CardUpgradeRecord record = builder.userId(userId)
									     .oldCardId(oldCard.getId())
									     .newCardId(newCard.getId())
									     .oldGrade(oldCard.getGrade())
									     .newGrade(newCard.getGrade())
									     .oldCardName(oldCard.getCardName())
									     .newCardName(newCard.getCardName())
									     .gradeCondition(newCard.getGradeCondition())
									     .operate(operate)
									     .build();
		record.insert();
	}
}
