1、到微信官網申請測試帳號?
申請地址：http://mp.weixin.qq.com/debug/cgi-bin/sandboxinfo?action=showinfo&t=sandbox/index?
點擊登錄后，用自己的微信掃描
2、在Eclipse中配置Tomcat?
在window->preferences->server->runtime environments?
2、打開Eclipse，創建一個web項目?
我的eclipse默認的jdk是1.5的，這里，我們需要將jdk修改成1.7的。：在項目上點擊右鍵，選擇build path，選中configure build path，將libraries中的jdk1.5選中，點擊edit，修改成1.7的。?
3、導入jar包?
jeecg-api包依賴其他九個包，一塊兒導入?
選中這些包，點擊右鍵，build path ，點擊add to build path，這樣，所有的jar都被添加到項目中去了?
4、創建表單頁面?
在WebContent目錄中創建一個index.jsp頁面
Html代碼??
<body>??<form?action="ApiDemo"?method="post">?????????<table>??????????????????<tr>??????????????????????????<td>appId</td>??????????????????????????<td><input?type="text"?id="appId"?name="appId"?/></td>??????????????????</tr>?????????????????<tr>??????????????????????????<td>appSecret</td>?????????????????????????<td><input?type="text"?id="appSecret"?name="appSecret"?/></td>?????????????????</tr>?????????????????<tr>?????????????????????????<td?colspan="2"?align="center"><input?type="submit"?value="提交"?/></td>?????????????????</tr>??????????</table>??</form>??<%??/*?獲取后臺傳過來的內容?*/??String?data?=?(String)session.getAttribute("data");??%>??<%=data?%>??</body>???
5、創建servlet?
新創建一個servlet會報錯，這個一般是缺少jar導致的，這時候，我們不需要從外部導入，在build path中將tomcat的包加過來即可添加方法?
在項目上點擊右鍵?
build path->configure build path->libraries->add library->server runtime?
6、在doPost方法中，寫：
?
?
Java代碼??
???request.setCharacterEncoding("utf-8");????????????String?appid?=?request.getParameter("appId");??????????String?appsecret?=?request.getParameter("appSecret");????????????if(StringUtils.isNotBlank(appid)?&&?StringUtils.isNotBlank(appsecret)){????????????????????????String?token?=?null;????????????????????????try?{????????????????????????????????????token?=?JwTokenAPI.getAccessToken(appid,?appsecret);??????????????????}?catch?(WexinReqException?e)?{??????????????????}??????????????????List<Wxuser>?users?=?null;????????????????????????try?{??????????????????????????users?=?JwUserAPI.getAllWxuser(token,?null);??????????????????}?catch?(WexinReqException?e)?{??????????????????}??????????????????StringBuffer?result?=?new?StringBuffer();????????????????????????for?(Wxuser?wxuser?:?users)?{??????????????????????????result.append("國家："+wxuser.getCountry()+"?城市："+wxuser.getCity()+"?性別："+wxuser.getSex()+"<br/>");??????????????????}????????????????????????request.getSession().setAttribute("data",?result.toString());????????????????????????response.sendRedirect("index.jsp");??????????}??
7、web.xml文件中
Xml代碼??
<?xml?version="1.0"?encoding="UTF-8"?>??<web-app?xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"?xmlns="http://java.sun.com/xml/ns/javaee"?xsi:schemaLocation="http://java.sun.com/xml/ns/javaee?http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"?id="WebApp_ID"?version="2.5">????????<display-name>apiDemo</display-name>????????<welcome-file-list>??????????????<welcome-file>index.html</welcome-file>??????????????<welcome-file>index.htm</welcome-file>??????????????<welcome-file>index.jsp</welcome-file>??????????????<welcome-file>default.html</welcome-file>??????????????<welcome-file>default.htm</welcome-file>??????????????<welcome-file>default.jsp</welcome-file>????????</welcome-file-list>????????<servlet>??????????????<description></description>??????????????<display-name>ApiDemo</display-name>??????????????<servlet-name>ApiDemo</servlet-name>??????????????<servlet-class>apiDemo.userServiceTest.ApiDemo</servlet-class>????????</servlet>????????<servlet-mapping>??????????????<servlet-name>ApiDemo</servlet-name>??????????????<url-pattern>/ApiDemo</url-pattern>????????</servlet-mapping>??</web-app>???
8、運行tomcat服務器?
頁面：?
在里面輸入appId和appSecret點擊提交，下面會返回對應的結果：?
