min-wechat 本项目基于Jfinal

1、WeixinConfig

public class WeixinConfig extends JFinalConfig {
	public void configConstant(Constants me) {
		loadPropertyFile("a_little_config.txt");
		me.setDevMode(getPropertyToBoolean("devMode", false));
		
		// 配置微信 API 相关常量
		ApiConfig.setDevMode(me.getDevMode());
		ApiConfig.setUrl(getProperty("url"));
		ApiConfig.setToken(getProperty("token"));
		ApiConfig.setAppId(getProperty("appId"));
		ApiConfig.setAppSecret(getProperty("appSecret"));
	}
	
	public void configRoute(Routes me) {
		me.add("/weixin", DemoController.class);
		me.add("/api", ApiController.class, "/api");
	}
	
	public void configPlugin(Plugins me) {}
	public void configInterceptor(Interceptors me) {}
	public void configHandler(Handlers me) {}
}

通过 ApiConfig 提供 Weixin 公众平台所需的相关配置，并在configRoute 方法配置路由

2、DemoController

public class DemoController extends WeixinController {
	protected void processInTextMsg(InTextMsg inTextMsg) {
		String msgContent = inTextMsg.getContent().trim();
		// 帮助提示
		if ("help".equalsIgnoreCase(msgContent)) {
			OutTextMsg outMsg = new OutTextMsg(inTextMsg);
			outMsg.setContent(helpStr);
			render(outMsg);
		}
		// 图文消息测试
		else if ("news".equalsIgnoreCase(msgContent)) {
			OutNewsMsg outMsg = new OutNewsMsg(inTextMsg);
			outMsg.addNews("图文消息title", "图文消息description", "图文消息片 url", "图文消息 url");
			render(outMsg);
		}
		// 音乐消息测试
		else if ("music".equalsIgnoreCase(msgContent)) {
			OutMusicMsg outMsg = new OutMusicMsg(inTextMsg);
			outMsg.setTitle("Listen To Your Heart");
			outMsg.setDescription("建议在 WIFI 环境下流畅欣赏此音乐");
			outMsg.setMusicUrl("http://www.jfinal.com/Listen_To_Your_Heart.mp3");
			outMsg.setHqMusicUrl("http://www.jfinal.com/Listen_To_Your_Heart.mp3");
			outMsg.setFuncFlag(true);
			render(outMsg);
		}
		else if ("美女".equalsIgnoreCase(msgContent)) {
			OutNewsMsg outMsg = new OutNewsMsg(inTextMsg);
			outMsg.addNews("秀色可餐", "JFinal Weixin 极速开发就是这么爽，有木有 ^_^", "http://mmbiz.qpic.cn/mmbiz/zz3Q6WSrzq2GJLC60ECD7rE7n1cvKWRNFvOyib4KGdic3N5APUWf4ia3LLPxJrtyIYRx93aPNkDtib3ADvdaBXmZJg/0", "http://mp.weixin.qq.com/s?__biz=MjM5ODAwOTU3Mg==&mid=200987822&idx=1&sn=7eb2918275fb0fa7b520768854fb7b80#rd");
			render(outMsg);
		}
		// 其它文本消息直接返回原值 + 帮助提示
		else {
			OutTextMsg outMsg = new OutTextMsg(inTextMsg);
			outMsg.setContent("\t文本消息已成功接收，内容为： " + inTextMsg.getContent() + "\n\n" + helpStr);
			render(outMsg);
		}
	}
	
	protected void processInImageMsg(InImageMsg inImageMsg) {
		OutImageMsg outMsg = new OutImageMsg(inImageMsg);
		// 将刚发过来的图片再发回去
		outMsg.setMediaId(inImageMsg.getMediaId());
		render(outMsg);
	}
	
	protected void processInVoiceMsg(InVoiceMsg inVoiceMsg) {
		OutVoiceMsg outMsg = new OutVoiceMsg(inVoiceMsg);
		// 将刚发过来的语音再发回去
		outMsg.setMediaId(inVoiceMsg.getMediaId());
		render(outMsg);
	}
	
	protected void processInVideoMsg(InVideoMsg inVideoMsg) {
		/* 腾讯 api 有 bug，无法回复视频消息，暂时回复文本消息代码测试
		OutVideoMsg outMsg = new OutVideoMsg(inVideoMsg);
		outMsg.setTitle("OutVideoMsg 发送");
		outMsg.setDescription("刚刚发来的视频再发回去");
		// 将刚发过来的视频再发回去，经测试证明是腾讯官方的 api 有 bug，待 api bug 却除后再试
		outMsg.setMediaId(inVideoMsg.getMediaId());
		render(outMsg);
		*/
		OutTextMsg outMsg = new OutTextMsg(inVideoMsg);
		outMsg.setContent("\t视频消息已成功接收，该视频的 mediaId 为: " + inVideoMsg.getMediaId());
		render(outMsg);
	}
	
	protected void processInLocationMsg(InLocationMsg inLocationMsg) {
		OutTextMsg outMsg = new OutTextMsg(inLocationMsg);
		outMsg.setContent("已收到地理位置消息:" +
							"\nlocation_X = " + inLocationMsg.getLocation_X() +
							"\nlocation_Y = " + inLocationMsg.getLocation_Y() + 
							"\nscale = " + inLocationMsg.getScale() +
							"\nlabel = " + inLocationMsg.getLabel());
		render(outMsg);
	}
	
	protected void processInLinkMsg(InLinkMsg inLinkMsg) {
		OutNewsMsg outMsg = new OutNewsMsg(inLinkMsg);
		outMsg.addNews("链接消息已成功接收", "链接使用图文消息的方式发回给你，还可以使用文本方式发回。点击图文消息可跳转到链接地址页面，是不是很好玩 :)" , "http://mmbiz.qpic.cn/mmbiz/zz3Q6WSrzq1ibBkhSA1BibMuMxLuHIvUfiaGsK7CC4kIzeh178IYSHbYQ5eg9tVxgEcbegAu22Qhwgl5IhZFWWXUw/0", inLinkMsg.getUrl());
		render(outMsg);
	}
	
	protected void processInFollowEvent(InFollowEvent inFollowEvent) {
		OutTextMsg outMsg = new OutTextMsg(inFollowEvent);
		outMsg.setContent("感谢关注 JFinal Weixin 极速开发，为您节约更多时间，去陪恋人、家人和朋友 :) \n\n\n " + helpStr);
		// 如果为取消关注事件，将无法接收到传回的信息
		render(outMsg);
	}
	
	protected void processInQrCodeEvent(InQrCodeEvent inQrCodeEvent) {
		OutTextMsg outMsg = new OutTextMsg(inQrCodeEvent);
		outMsg.setContent("processInQrCodeEvent() 方法测试成功");
		render(outMsg);
	}
	
	protected void processInLocationEvent(InLocationEvent inLocationEvent) {
		OutTextMsg outMsg = new OutTextMsg(inLocationEvent);
		outMsg.setContent("processInLocationEvent() 方法测试成功");
		render(outMsg);
	}
	
	protected void processInMenuEvent(InMenuEvent inMenuEvent) {
		OutTextMsg outMsg = new OutTextMsg(inMenuEvent);
		outMsg.setContent("processInMenuEvent() 方法测试成功");
		render(outMsg);
	}
	
	protected void processInSpeechRecognitionResults(InSpeechRecognitionResults inSpeechRecognitionResults) {
		OutTextMsg outMsg = new OutTextMsg(inSpeechRecognitionResults);
		outMsg.setContent("processInSpeechRecognitionResults() 方法测试成功");
		render(outMsg);
	}
}

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、ApiController

public class ApiController extends Controller {
	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());
	}
}

通过调用 MenuApi、UserApi 等 Api 的相关方法即可获取封装成 ApiResult 对象的结果，使用 render 系列方法即可快捷输出结果
