java微信开发API demo JDK

# Jfinal Weixin 极速开发 JFinal Weixin 是基于 JFinal 的微信公众号极速开发 SDK，只需浏览 Demo 代码即可进行极速开发，自 JFinal Weixin 1.2 版本开始已添加对多公众号支持。 ## 1、WeixinConfig配置 `详情请见`：[JFinal weixin中的WeixinConfig配置](http://git.oschina.net/jfinal/jfinal-weixin/wikis/JFinal-weixin%E4%B8%AD%E7%9A%84WeixinConfig%E9%85%8D%E7%BD%AE) ## 2、WeixinMsgController ``` java public class WeixinMsgController extends MsgController { protected void processInTextMsg(InTextMsg inTextMsg) { String msgContent = inTextMsg.getContent().trim();

ac.setEncodingAesKey(PropKit.get("encodingAesKey", "setting it in config file")); return ac; } } ``` DemoController 通过继承自 WeixinController 便拥有了接收消息和发送消息的便利方法 ## 3、WeixinApiController ``` java public class WeixinApiController extends ApiController { public void index() { render("/api/index.html"); } /** * 获取公众号菜单 */ public void getMenu() { ApiResult apiResult = MenuApi.getMenu(); if (apiResult.isSucceed()) renderText(apiResult.getJson()); else renderText(apiResult.getErrorMsg()); } /** * 获取公众号关注用户 */ public void getFollowers() { ApiResult apiResult = UserApi.getFollows(); renderText(apiResult.getJson()); } /** * 如果要支持多公众账号，只需要在此返回各个公众号对应的 ApiConfig 对象即可 * 可以通过在请求 url 中挂参数来动态从数据库中获取 ApiConfig 属性值 */ public ApiConfig getApiConfig() { ApiConfig ac = new ApiConfig(); // 配置微信 API 相关常量 ac.setToken(PropKit.get("token")); ac.setAppId(PropKit.get("appId")); ac.setAppSecret(PropKit.get("appSecret")); /** * 是否对消息进行加密，对应于微信平台的消息加解密方式： * 1：true进行加密且必须配置 encodingAesKey * 2：false采用明文模式，同时也支持混合模式 */ ac.setEncryptMessage(PropKit.getBoolean("encryptMessage", false)); ac.setEncodingAesKey(PropKit.get("encodingAesKey", "setting it in config file")); return ac; } } ``` 通过调用 MenuApi、UserApi 等 Api 的相关方法�
