工厂模式和策略模式的使用

1.TemplateAbstract---消息模板抽象类（策略模式）

import com.danga.MemCached.MemCachedClient; import com.google.gson.Gson; import com.zhuzher.common.v3.po.AuthUser; import com.zhuzher.commons.util.Constants; import com.zhuzher.commons.util.StringUtil; import com.zhuzher.commons.util.Tools; import com.zhuzher.commons.util.WechatKit; import com.zhuzher.vxs.dao.WinxinDao; import com.zhuzher.vxs.po.AuthInfo; import com.zhuzher.vxs.po.ReportThird; import com.zhuzher.wechat.message.po.TemplateData; import org.apache.log4j.Logger; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Scope; import org.springframework.stereotype.Component; import java.io.IOException; import java.security.KeyManagementException; import java.security.NoSuchAlgorithmException; import java.security.NoSuchProviderException; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import java.util.concurrent.ExecutionException; /** * @authuser tk * @description 消息模板抽象类 * @date 2019/6/12 */ @Component @Scope("prototype") public abstract class TemplateAbstract { Logger log= Logger.getLogger(TemplateAbstract.class); @Autowired WechatKit wechatKit; @Autowired public WinxinDao winxinDao; private static final String DEFAULT_COLOR = "#173177"; protected TemplateData templateData = new TemplateData(); protected List> dataList = new ArrayList>(); protected List keyList; protected String token; protected String openid; protected String tmpid; protected String wxcid; /** * init template id */ public abstract void buildTemplateId(); /** * init template key name */ public abstract void buildKey(); /** * create default skip url, if have not skip url , set blank hahhhh` */ public void createDefaultSkipUrl(){}; /** * init skip url * @param url * @return */ public TemplateAbstract pushSkipUrl(String url){ templateData.setUrl(url); return this; } /** * init key value * @param value * @return */ public TemplateAbstract pushData(String value){ pushData(value, DEFAULT_COLOR); return this; } /** * init key and color * @param value * @param color * @return */ public TemplateAbstract pushData(String value, String color){ Map item = new HashMap(); item.put("value", value); item.put("color", color); dataList.add(item); return this; } /** * match key and data */ public void buildData(){ for(int i = 0; i < dataList.size(); i++){ templateData.push(keyList.get(i), dataList.get(0).get("value"), dataList.get(0).get("color")); } } /** * init wxcid and sender * @param wxcid * @param openid * @return */ public TemplateAbstract initParams(String wxcid, String openid){ AuthUser authuser_new = wechatKit.getAuthUser(wxcid); if(authuser_new != null){ this.token = authuser_new.getAuthorizer_access_token(); } return this; } private void skipUrlHandleMethod(){ if(StringUtil.isBlank(templateData.getUrl())){ createDefaultSkipUrl(); } } /** * invoke wechat msg */ protected void sendWechatMsg(){ try { log.debug("1-----发送模板消息----sendWechatMsg:"+(templateData == null ? null : (new Gson().toJson(templateData)))+";token:"+token); WechatKit.templateSend(token, templateData); } catch (IOException e) { e.printStackTrace(); } catch (ExecutionException e) { e.printStackTrace(); } catch (InterruptedException e) { e.printStackTrace(); } catch (KeyManagementException e) { e.printStackTrace(); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (NoSuchProviderException e) { e.printStackTrace(); } } /** * send msg(outer accesss) */ public void sendMsg(){ //初始化模版id buildTemplateId(); //初始化当前要发送的模版类型的keyname buildKey(); //初始化默认的跳转地址url skipUrlHandleMethod(); //把key和data对应起来 buildData(); //发送消息 sendWechatMsg(); } }

 

2.TemplateFactory--消息模板工厂类（工厂模式）

import com.zhuzher.template.abstracts.TemplateAbstract; import com.zhuzher.template.service.impl.*; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import java.util.Map; /** * @authuser tk * @description 消息模板工厂类 * @date 2019/6/12 */ @Component public class TemplateFactory { @Autowired RegisterSuccessTemplate registerSuccessTemplate; @Autowired RewardAccountEntryTemplate rewardAccountEntryTemplate; @Autowired OrderPaySuccessTemplate orderPaySuccessTemplate; @Autowired IntegralExchangeSuccessTemplate integralExchangeSuccessTemplate; @Autowired ConsultationReplyTemplate consultationReplyTemplate; public TemplateAbstract createTemplate(Integer typeid, String wxcid, String openid) { switch (typeid) { case 2 : //2-积分兑换成功通知 return integralExchangeSuccessTemplate.initParams(wxcid, openid); case 94 : //94-订单支付成功通知 return orderPaySuccessTemplate.initParams(wxcid, openid); case 100 : //100-粉丝成功注册提醒 return registerSuccessTemplate.initParams(wxcid, openid); case 103 : //103-会员权益到账通知 return rewardAccountEntryTemplate.initParams(wxcid, openid); case 104 : //104-咨询回复消息提醒 return consultationReplyTemplate.initParams(wxcid, openid); } return null; } }

 

3.RewardAccountEntryTemplate--实现类（会员权益到账通知）

package com.zhuzher.template.service.impl; import com.zhuzher.commons.util.Constants; import com.zhuzher.template.abstracts.TemplateAbstract; import com.zhuzher.vxs.po.TemplateValue; import com.zhuzher.wechat.message.po.TemplateData; import org.springframework.stereotype.Component; import java.util.Arrays; import java.util.HashMap; /** * @authuser tk * @description 103----会员权益到账通知 * @date 2019/6/12 */ @Component public class RewardAccountEntryTemplate extends TemplateAbstract { private String[] keyName ; private String[] keyName_old = {"first", "keyword1", "keyword2", "keyword3", "keyword4", "remark"}; private String[] keyName_new = {"first", "keyword1", "keyword2", "keyword3", "remark"}; private static String DEFAULT_SKIP_URL =Constants.SETTINGMAP.get(Constants.SETTING_BASE_URL_WX)+"/view/ticketManager.html?cid="; private Boolean version = false;//默认旧模板 @Override public void buildTemplateId() { TemplateValue templateValue = winxinDao.queryTemplateValue(wxcid, 1, 103); if (templateValue != null) { super.tmpid = templateValue.getValue(); } //判断当前酒店使用的模板是旧模板还是新模板 if(templateValue.getUpdate_times() == TemplateValue.SET_UPDATE_TIMES_1){ version=true; } if(version){//新模板--2019年04月19日 this.keyName = keyName_old; }else{ this.keyName = keyName_new; } } @Override public void buildKey() { super.keyList = Arrays.asList(keyName); } @Override protected void sendWechatMsg() { //新模板 if(version){ templateData.push("first", templateData.getData() .get("first") .getValue()+"，会员卡号："+templateData.getData().get("keyword1").getValue() ); HashMap keyWordMap = templateData.getData(); for(String key: keyWordMap.keySet()){ if (key.equals("keyword1")){ keyWordMap.put(key,keyWordMap.get("keyword2")); } if (key.equals("keyword2")){ keyWordMap.put(key,keyWordMap.get("keyword3")); } if (key.equals("keyword3")){ keyWordMap.put(key,keyWordMap.get("keyword4")); } } keyWordMap.remove("keyword4"); } super.sendWechatMsg(); } /** * 创建默认的跳转地址 */ @Override public void createDefaultSkipUrl(){ super.templateData.setUrl(DEFAULT_SKIP_URL + wxcid); } }

4.WinxinServiceImpl--业务层实现类

TemplateAbstract templateAbstract = templateFactory.createTemplate(103, wxcid, openid); templateAbstract .pushData(first) .pushData(cardno) .pushData(keyword2) .pushData(sourceStr) .pushData(DateDiff.currentDateTime()); templateAbstract.sendMsg();
