四、在项目中配置使用

后台代码如下，用到的字段根据自己的项目进行修改，各类id自行获取(AppID可在基本配置中查看)

//推送公众号模板消息
				String template_id = "";//模板id

				String sh = "";
				if(aa.equals("Y")){
					sh = "已审核";
				}else if(aa.equals("N")){
					sh = "审核未通过";
				}else{
					sh = "待审核";
				}
				try {
					//if(bb.equals("")){}
					String firstDATA="你好，你提交的审批已审核";					
					String keyword1DATA=sh;
					String keyword2DATA=aud_ex5+aud_ex6+aud_ex8;
					String remarkDATA="请进入公众号查看";

					//跳转路径
					String url = "";

					Map<String,Object> mapParam = new HashMap<String,Object>();
					mapParam.put("firstDATA", firstDATA);
					mapParam.put("keyword1DATA", keyword1DATA);
					mapParam.put("keyword2DATA", keyword2DATA);
					mapParam.put("remarkDATA", remarkDATA);
					mapParam.put("url", url);
					mapParam.put("OPENID", "oyOK25vBHQKEsrodfCPDS2OiUrbQ");//微信用户openid
					String jsonParam = "{\"touser\":\""+mapParam.get("OPENID")+"\",\"template_id\":\""+template_id+"\","
						+ "\"url\":\""+mapParam.get("url")+"\","
						+ "\"data\": {\"first\":{\"value\": \""+mapParam.get("firstDATA")+"\",\"color\":\"#555e94\""+"},"
						+ "\"keyword1\":{\"value\": \""+mapParam.get("keyword1DATA")+"\",\"color\":\"#555e94\""+"},"
						+ "\"keyword2\":{\"value\": \""+mapParam.get("keyword2DATA")+"\",\"color\":\"#555e94\""+"},"
						+ "\"remark\":{\"value\": \""+mapParam.get("remarkDATA")+"\",\"color\":\"#555e94\""+"}"
						+ "}}";

					//公众号模版消息接口请求地址			
					String sendMsgUrl = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=";
					//String 
					String access_token = "";
					//静态缓存存储令牌2小时过期
					Cache c = CacheManager.getCacheInfo("access_token");
					System.out.print("令牌获取"+(c!=null));
					if(c!=null&&!c.isExpired()){
						access_token = c.getValue().toString();
						System.out.print("令牌获取"+access_token);
					}else{
						System.out.print("令牌过期重新获取");
						access_token = OAuthUtil.getNewsAccessToken("","");//前者为appId,后者为secret
						//设置过期时间
						c = new Cache("access_token",access_token,2*60*60*1000,false);
						CacheManager.putCache("access_token",c);
					}
					//System.out.print("uuuuuuuuuuuuu");
					sendMsgUrl = sendMsgUrl + access_token;
					//System.out.print("sendMsgUrl="+sendMsgUrl);
					Map<String, String> headerMap = new HashMap<String, String>();
					headerMap.put("Content-Type", "application/json");
					String result = HttpClientUtil.doHttpsPost(sendMsgUrl, headerMap, jsonParam, "utf-8");
					System.out.print("result="+result);
				} catch (Exception e) {
					System.out.println(e.getMessage());
				}

五、遇见的问题

1、遇见了40001错误
官网提示为AppSecret错误或者AppSecret不属于这个公众号，请开发者确认AppSecret的正确性
我的解决方式为：
配置白名单
找到基本配置

查看ip白名单

将自己电脑的ip地址加上去即可
