前言?

在我看來多寫幾個if-else沒啥大不了的，但是就是看起來沒啥逼格，領(lǐng)導(dǎo)嫌棄。我根據(jù)開發(fā)的經(jīng)歷寫幾個不同的替代方法

一、枚舉法替代?

我先前寫了一篇文章，可以去看看。

通過枚舉替換if-else語句的解決方案_枚舉代替if else c語言-CSDN博客

二、定義接口，實現(xiàn)類

通過定義初始方法，通過添加多個實現(xiàn)類來選擇

• 接口

public interface ISoapServer {/*** 服務(wù)編碼* @return*/String getCode();/*** 服務(wù)* @param xml* @return*/String server(String xml);}

• 實現(xiàn)類

?其中一個實現(xiàn)類，其他的類似

import cn.hutool.core.convert.Convert;

@Service

}

?使用方法

 public String HIPMessageServer(String action, String message) {String result ="";log.info("\n 交互服務(wù)入?yún)⑿畔? \n action:{} \n message:{}",action,message);String[] beanNamesForType = applicationContext.getBeanNamesForType(ISoapServer.class);for (String beanName : beanNamesForType) {ISoapServer soapServer = applicationContext.getBean(beanName, ISoapServer.class);if (soapServer.getCode().equals(action)) {result = soapServer.server(message);log.info("\n 交互服務(wù)出參信息: \n message:{}",result);return result;}}return result;}

三、Map+函數(shù)式接口

@Service??
public?class?GrantTypeSerive?{??public?String?redPaper(String?resourceId){??//紅包的發(fā)放方式??return?"每周末9點發(fā)放";??}??public?String?shopping(String?resourceId){??//購物券的發(fā)放方式??return?"每周三9點發(fā)放";??}??public?String?QQVip(String?resourceId){??//qq會員的發(fā)放方式??return?"每周一0點開始秒殺";??}??
}?

@Service??
public?class?QueryGrantTypeService?{??@Autowired??private?GrantTypeSerive?grantTypeSerive;??private?Map<String,?Function<String,String>>?grantTypeMap=new?HashMap<>();??/**??*??初始化業(yè)務(wù)分派邏輯,代替了if-else部分??*??key:?優(yōu)惠券類型??*??value:?lambda表達式,最終會獲得該優(yōu)惠券的發(fā)放方式??*/??@PostConstruct??public?void?dispatcherInit(){??grantTypeMap.put("紅包",resourceId->grantTypeSerive.redPaper(resourceId));??grantTypeMap.put("購物券",resourceId->grantTypeSerive.shopping(resourceId));??grantTypeMap.put("qq會員",resourceId->grantTypeSerive.QQVip(resourceId));??}??public?String?getResult(String?resourceType){??//Controller根據(jù)?優(yōu)惠券類型resourceType、編碼resourceId?去查詢?發(fā)放方式grantType??Function<String,String>?result=getGrantTypeMap.get(resourceType);??if(result!=null){??//傳入resourceId?執(zhí)行這段表達式獲得String型的grantType??return?result.apply(resourceId);??}??return?"查詢不到該優(yōu)惠券的發(fā)放方式";??}??
