设计模式-策略模式

策略模式：

　　属于行为模式,包含一个策略接口Strategy，四个以下（大于四个可以使用混合模式）的策略实现类，

　　一个使用该策略的类Context

实例：两个角色厅店和能人都有一个酬金明细，一个是分页查询厅店发放的酬金明细，一个是分页查询能人提现的酬金明细

1.一个策略接口Strategy

/**
 * 抽象酬金明细接口
 */
public interface MoneyDetailListPageStrategy {
    /**分页数据接口*/
    ResultJson getMoneyDetailListPage(MoneyDetailListPageVo pageVo, CpUserInfoDto userInfo);
}

2。策略实现类

　　2.1 能人角色的提现酬金明细

3.调用分页查询酬金明细的context类（spring的构造器注入）

 1 package com.inphase.demo.handler;
 2 
 3 import com.inphase.demo.common.domain.ResultJson;
 4 import com.inphase.demo.entity.CpUserInfoDto;
 5 import com.inphase.demo.vo.MoneyDetailListPageVo;
 6 import org.springframework.beans.factory.annotation.Autowired;
 7 import org.springframework.stereotype.Component;
 8 
 9 import java.util.Map;
10 import java.util.concurrent.ConcurrentHashMap;
11 @Component
12 public class MoneyDetailListPageContext {
13 
14     @Autowired
15     private Map<String, MoneyDetailListPageStrategy> strategyMap = new ConcurrentHashMap<>();
16 
17     public MoneyDetailListPageContext(Map<String, MoneyDetailListPageStrategy> strategyMap) {
18         this.strategyMap.clear();
19         strategyMap.forEach((k, v)-> this.strategyMap.put(k, v));
20     }
21 
22     public ResultJson getMoneyDetailListPage(String strategy, MoneyDetailListPageVo listPageVo, CpUserInfoDto userInfo){
23         return strategyMap.get(strategy).getMoneyDetailListPage(listPageVo,userInfo);
24     }
25 
26 }

4.调用不同的策略的Service层，其实也可以Service层作为context

 1 /**
 2  * 用户登录注册
 3  */
 4 @Service
 5 @Slf4j
 6 @Transactional
 7 public class CpUserService {
 8      @Resource
 9     private MoneyDetailListPageContext moneyDetailListPageContext;
10     
11         /**
12      * 获取金额明细信息
13      * @param listPageVo 查询条件
14      * @return 查询结果
15      */
16     public ResultJson getMoneyDetailListPage(MoneyDetailListPageVo listPageVo,CpUserInfoDto userInfo) {
17         log.info("请求参数：MoneyDetailListPageVo==>"+listPageVo);
18         log.info("请求参数：CpUserInfoDto==>"+userInfo);
19         ResultJson resultJson;
20         switch (listPageVo.getCpType()){
21             case 1:
22                 resultJson = moneyDetailListPageContext.getMoneyDetailListPage("AblePersonMoneyDetailListPageStrategy", listPageVo, userInfo);
23                 break;
24             case 2:
25                 resultJson = moneyDetailListPageContext.getMoneyDetailListPage("HallMoneyDetailListPageStrategy", listPageVo, userInfo);
26                 break;
27             default:
28                 resultJson = ResultJson.error("请求参数cpType错误："+listPageVo.getCpType());
29         }
30         return resultJson;
31     }
32 }
