SendPhoneVerifyCode----->ajax发送数据的后端servlet，接收前端发来的电话号码，并执行发送验证码的动作
public class SendPhoneVerifyCode extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html;charset=utf-8");
//获取电话号码
String phone = request.getParameter("phone");
//给当前号码发送验证码,返回验证码存在session里，就是这里把我限制了，云信都登不上了，不过不影响使用
String code = new PhoneVerifyCode(phone).sendCode();
request.getSession().setAttribute("phoneCode",code);//session是存在于服务器上滴，cookie是在客户端滴
//将json数据返回前端，提示用户
response.getWriter().write("{\"message\":\"信息已发送\"}");
}
}
PhoneVerifyCode--->网易云信的提示中有代码，记得在copy一下它的CheckSumBuilder类，会用到，还要添加两个JAR包httpcore-4.4.3.jar和httpclient-4.5.1.jar，如果报错中有logging等字眼，再添加com.springsource.org.apache.commons.logging-1.1.1.jar
public class PhoneVerifyCode {
//发送验证码的请求路径URL
private static final String
SERVER_URL="https://api.netease.im/sms/sendcode.action";
//网易云信分配的账号，请替换你在管理后台应用下申请的Appkey
private static final String
APP_KEY="d39afb7b5b9ece021935351e74f75d98";
//网易云信分配的密钥，请替换你在管理后台应用下申请的appSecret
private static final String APP_SECRET="543d6e574be7";
//随机数
private static final String NONCE="123456";
//短信模板ID
private static final String TEMPLATEID="4062279";
//手机号
private static String MOBILE="";
//验证码长度，范围4～10，默认为4
private static final String CODELEN="6";
public PhoneVerifyCode(String MOBILE){
this.MOBILE=MOBILE;
}
public String sendCode(){
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(SERVER_URL);
String curTime = String.valueOf((new Date()).getTime() / 1000L);
/*
* 参考计算CheckSum的java代码，在上述文档的参数列表中，有CheckSum的计算文档示例
*/
String checkSum = CheckSumBuilder.getCheckSum(APP_SECRET, NONCE, curTime);
// 设置请求的header
httpPost.addHeader("AppKey", APP_KEY);
httpPost.addHeader("Nonce", NONCE);
httpPost.addHeader("CurTime", curTime);
httpPost.addHeader("CheckSum", checkSum);
httpPost.addHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");
// 设置请求的的参数，requestBody参数
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
/*
* 1.如果是模板短信，请注意参数mobile是有s的，详细参数配置请参考“发送模板短信文档”
* 2.参数格式是jsonArray的格式，例如 "[‘13888888888‘,‘13666666666‘]"
* 3.params是根据你模板里面有几个参数，那里面的参数也是jsonArray格式
*/
nvps.add(new BasicNameValuePair("templateid", TEMPLATEID));
nvps.add(new BasicNameValuePair("mobile", MOBILE));
nvps.add(new BasicNameValuePair("codeLen", CODELEN));
try {
httpPost.setEntity(new UrlEncodedFormEntity(nvps, "utf-8"));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
// 执行请求
HttpResponse response = null;
try {
response = httpClient.execute(httpPost);
} catch (IOException e) {
e.printStackTrace();
}
/*
* 1.打印执行结果，打印结果一般会200、315、403、404、413、414、500
* 2.具体的code有问题的可以参考官网的Code状态表
*/
String respJSON= null;
try {
respJSON = EntityUtils.toString(response.getEntity(), "utf-8");
System.out.println(respJSON);
} catch (IOException e) {
e.printStackTrace();
}
Gson gson=new Gson();
CodeEntity entity = gson.fromJson(respJSON, CodeEntity.class);
String ss=entity.getObj();
//因为把我限制了，导致给我的验证码格式不对，截取前面的即是验证码，正常用户直接getobj()即是验证码，没办法被限制了...
System.out.println(ss.substring(0,7));
return ss.substring(0,7);
}
}
UserRegisterServlet---->用户注册判断用户填写的数据是否可以注册的servlet
public class UserRegisterServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String username = request.getParameter("r_username");
String password = request.getParameter("r_password");
String telephone = request.getParameter("r_telephone");
String phoneVerifyCode = request.getParameter("phoneVerifyCode");
User user=new User(username, MD5Util.md5(password),telephone);
//开始注册业务
UserRegister userRegister=new Dao.UserRegister();
if(userRegister.isRepeatUsername(username)){
request.getSession().setAttribute("messageShow","用户名重复");
response.sendRedirect("Register.jsp");
return;
}
if(!userRegister.isRightCode(phoneVerifyCode, (String) request.getSession().getAttribute("phoneCode"))){
request.getSession().setAttribute("messageShow","验证码错误");
response.sendRedirect("Register.jsp");
return;
}
userRegister.insertUser(user);
request.getSession().setAttribute("username",username);
request.getRequestDispatcher("RegisterSuccess.jsp").forward(request,response);
}
}
UserRegister--->实现业务层的接口，对数据库进行CRUD操作的类
public class UserRegister implements Service.UserRegister{
private DataSource dataSource=new ComboPooledDataSource();
private QueryRunner qr=new QueryRunner(dataSource);
@Override
public boolean isRightCode(String code, String rightCode) {
return code.equalsIgnoreCase(rightCode);
}
@Override
public boolean isRepeatUsername(String username) {
User user=null;
try {
user = qr.query("select * from user where username=?", new BeanHandler<>(User.class), username);
} catch (SQLException e) {
e.printStackTrace();
}
return user!=null;
}
@Override
public void insertUser(User user) {
try {
qr.update("insert into user(username,password,telephone) values (?,?,?)",user.getUsername(),user.getPassword(),user.getTelephone());
} catch (SQLException e) {
e.printStackTrace();
}
}
}
以上为注册模块主要的代码，剩下的要么是实体类(User类用来封装用户输入的信息、CodeEntity类用来将手机验证码返回的jsonArray转为该对象)，要么是工具类(MD5加密密码)，要么就是业务层定义的接口(用户注册的功能设定)。
差不多就这样了，就不放上来了，这么多也不一定看的完..........代码臃肿，得治。。。注册短信验证码到这里就实现了，剩下邮件验证激活和登录......先放着。
收到的短信可以自己设置模板，但是要审核，不要刷的太频繁，不然o(￣ヘ￣o＃)---------->{"code":416,"msg":"mobile limit","obj":"4322605||+86-xxxxxxxxx"}，mobile limit,电话号码就xxxxx了。
注册成功后进入，邮箱激活界面，用户名可在注册的Sevlet中存session,在这个页面通过el获取-----.>

Jsp+Servlet+MYSQL注册登录案例(界面难看，ε=(´ο｀*)))唉)
