1.H5页面配置

(1)引入微信JS SDK

(2)在js里配置接口参数

wx.config({		debug : false,//这里是开启测试，如果设置为true，则打开每个步骤，都会有提示，是否成功或者失败 		appId : '${appid}',		timestamp : '${timestamp}',		nonceStr : '${nonceStr}',		signature : '${signature}',		jsApiList : [		// 所有要调用的 API 都要加到这个列表中 		'onMenuShareTimeline',"onMenuShareAppMessage","onMenuShareQQ","hideMenuItems"]	});	var strTiele="";	var strDesc="";	var strLink="url";	var strImgUrl="图片路径";	wx.ready(function() {		// 1 判断当前版本是否支持指定 JS 接口，支持批量判断		wx.checkJsApi({			jsApiList : ['"hideMenuItems"','onMenuShareTimeline','onMenuShareAppMessage',"onMenuShareQQ"],					});				//隐藏QQ空间分享,QQ浏览器，safari		wx.hideMenuItems({			menuList: ["menuItem:share:QZone","menuItem:openWithSafari","menuItem:openWithQQBrowser"] 		});				//分享朋友圈		wx.onMenuShareTimeline({			title : strTiele, // 分享标题 			 desc : strDesc,//分享描述			 link : strLink, // 分享链接 			imgUrl: strImgUrl,// 分享图标 					});				//分享给微信好友		wx.onMenuShareAppMessage({			title : strTiele, // 分享标题 			 desc : strDesc,//分享描述			 link : strLink, // 分享链接 			imgUrl: strImgUrl,// 分享图标 		});				//分享到QQ		wx.onMenuShareQQ({			title : strTiele, // 分享标题 			 desc : strDesc,//分享描述			 link : strLink, // 分享链接 			imgUrl: strImgUrl,// 分享图标 		});

　2.ACTION 类设置

String params = PastUtil.getParam("wx05a97b02437b983d","2a5ea68d9679b0de1ad09de72e4159fe");				JSONObject jsonObject = new JSONObject(params);		this.setResult("appid", jsonObject.get("appid"));		this.setResult("url", jsonObject.get("url"));		this.setResult("jsapi_ticket", jsonObject.get("jsapi_ticket"));		this.setResult("timestamp", jsonObject.get("timestamp"));		this.setResult("nonceStr", jsonObject.get("nonceStr"));		this.setResult("signature", jsonObject.get("signature"));

Pastutil 类

public class PastUtil {    public static String token = null;    public static String time = null;    public static String jsapi_ticket = null;    public static String url = null ;    /**     *      * @param appId   公账号appId     * @param appSecret     * @param url    当前网页的URL，不包含#及其后面部分     * @return     */    public static String getParam(String appId,String appSecret){        if(token == null){            token = CommonUtil.getToken(appId, appSecret);            jsapi_ticket = CommonUtil.getJsApiTicket(token);            time = getTime();        }else{            if(!time.substring(0, 13).equals(getTime().substring(0, 13))){ //每小时刷新一次                token = null;                token = CommonUtil.getToken(appId, appSecret);                jsapi_ticket = CommonUtil.getJsApiTicket(token);                time = getTime();            }        }                  String url = getUrl();                  Map
     
       params = sign(jsapi_ticket, url);        params.put("appid", appId);                  JSONObject jsonObject = JSONObject.fromObject(params);          String jsonStr = jsonObject.toString();        System.out.println(jsonStr);        return jsonStr;    }          private static String getUrl(){    	HttpServletRequest request = ActionContext.getActionContext().getRequest();           //StringBuffer requestUrl = request.getRequestURL();    	    	    	System.out.println(request.getServerName());    	//如果你的微信后台端口是80的话，一定不能把HTTP_HOST也拼接到url上面去，否则签名失败       		String share2FirendUrl = request.getScheme() + "://"+ request.getServerName() + ":" + request.getServerPort()+ request.getRequestURI();		System.out.println(share2FirendUrl);				//带参数的url拼接		if(StringUtils.isNotBlank(request.getQueryString())){			share2FirendUrl +=  "?"+request.getQueryString();		}		System.out.println("share2FirendUrl\n\n"+share2FirendUrl+"\n\n");        return share2FirendUrl;    }          public static Map
      
        sign(String jsapi_ticket, String url) {        Map
       
         ret = new HashMap
