Java用户注册服务器发送短信验证码功能实现

<–start–>
当客户端发送了http的请求给服务器之后，服务器获取手机号然后调用短信平台给该手机号发送短信验证码。
给服务器发送请求的js代码：

<script type="text/javascript">            // 模块定义             var signupApp = angular.module("signupApp", []);            // 控制器定义            signupApp.controller("signupCtrl", ["$scope","$http",function($scope,$http) {                $scope.btnMsg = "发送验证码";                var active = true;                var second = 60; // 倒计时60秒                var secondInterval;                $scope.getCheckCode = function(telephone) {                    if(active == false) {                        return;                    }                    // 1 发送一个HTTP请求，通知服务器 发送短信给目标用户                     var regex = /^1(3|5|7|8)\d{9}$/;                    if(regex.test(telephone)) {                        // 校验通过                        $http({                            method: 'GET',                            url: 'customer_sendSms.action',                            params : {                                telephone : telephone                            }                        }).error(function(data, status, headers, config) {                            // 当响应以错误状态返回时调用                            alert("发送短信出错，请联系管理员");                        });                    } else {                        // 校验失败                         alert("手机号非法，请重新输入 ");                        return;                    }</script>

在服务器端程序中的web.xml文件中要配置以下内容：
① struts2的核心拦截器StrutsPreparedAndExecuteFilter；
② spring的核心配置文件applicationContext.xml所在位置的classpath；
③ spring的核心监听器ContextLoaderListener。
完整的web.xml文件内容：

<?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">    <!-- spring配置文件位置 -->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext.xml</param-value>    </context-param>    <!-- spring核心监听器 -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!-- struts核心控制器 -->    <filter>        <filter-name>struts2</filter-name>        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>struts2</filter-name>        <url-pattern>/*</url-pattern>        <dispatcher>REQUEST</dispatcher>        <dispatcher>FORWARD</dispatcher>    </filter-mapping>    <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></web-app>

接下来在服务器端编写CustomerAction代码，获取传递过来的手机号码参数，然后给该手机号码发送短信。 鉴于大量Action的代码比如模型驱动接收参数，压入值栈等都是重复性的操作，所以有必要将这些代码抽取成一个类，让其他的子类Action去继承。BaseAction父类的代码如下：

public abstract class BaseAction<T> extends ActionSupport implements        ModelDriven<T> {    // 模型驱动    protected T model;    @Override    public T getModel() {        return model;    }    // 构造器 完成model实例化    public BaseAction() {        // 构造子类Action对象 ，获取继承父类型的泛型        Type genericSuperclass = this.getClass().getGenericSuperclass();        // 获取类型第一个泛型参数        ParameterizedType parameterizedType = (ParameterizedType) genericSuperclass;        Class<T> modelClass = (Class<T>) parameterizedType                .getActualTypeArguments()[0];        try {            model = modelClass.newInstance();        } catch (InstantiationException | IllegalAccessException e) {            e.printStackTrace();            System.out.println("模型构造失败...");        }    }}

创建CustomerAction类，在类上添加相关的注解：
① struts2的注解：@ParentPackage(“json-default”),@Namespace(“/”);
② spring的注解：@Controller,@Scope(“prototype”)

@ParentPackage("json-default")@Namespace("/")@Controller@Scope("prototype")public class CustomerAction extends BaseAction<Customer> { }

在本例中要使用到webservice的技术，CustomerAction要远程调用crm系统中crm_domain工程中的数据，因此要在CustomerAction所在项目中添加对crm_domain的依赖，具体要在pom.xml文件中实现。

<dependency>    <groupId>cn.niwotaxuexiba.maven</groupId>    <artifactId>crm_domain</artifactId>    <version>0.0.1-SNAPSHOT</version></dependency>

完整的pom.xml文件内容：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <parent>     <groupId>cn.niwotaxuexiba.maven</groupId>     <artifactId>common_parent</artifactId>     <version>0.0.1-SNAPSHOT</version>  </parent>    <artifactId>bos_fore</artifactId>  <packaging>war</packaging>  <name>bos_fore</name>  <description>物流前端系统</description>  <build>    <plugins>        <plugin>            <groupId>org.codehaus.mojo</groupId>            <artifactId>tomcat-maven-plugin</artifactId>            <version>1.1</version>            <configuration>                <port>9003</port>            </configuration>        </plugin>        <plugin>            <groupId>org.apache.maven.plugins</groupId>            <artifactId>maven-compiler-plugin</artifactId>            <version>2.3.2</version>            <configuration>                <source>1.8</source>                <target>1.8</target>            </configuration>        </plugin>    </plugins>  </build>  <dependencies>    <dependency>        <groupId>cn.niwotaxuexiba.maven</groupId>        <artifactId>crm_domain</artifactId>        <version>0.0.1-SNAPSHOT</version>    </dependency>  </dependencies></project>

在CustomerAction类中，编写一个sendSms的方法：
① 需要获取的手机号保存在Customer对象中,所以要用到webservice技术；
② 生成一个随机短信验证码，用到的是apache.commons.lang包下的RandomStringUtils类来生成随机验证码；
③ 将生成的短信验证码保存到session中，调用struts2的ServletActionContext获取request对象，然后存入session.保存到session的方法ServletActionContext.getRequest().setAttribute(model.getTelephone(),randomCode);
④ 生成要发送的短信正文内容，其实就是生成一个字符串；
⑤ 调用SMS服务发送短信（发送短信的工具类SmsUtils已经在下面提供）；
⑥ 发送短信的途径有http和webservice两种，http的方式将返回000，webservice将返回16位的一个字符串，本例中使用http的方式。
完整的CustomerAction代码如下：

@ParentPackage("json-default")@Namespace("/")@Controller@Scope("prototype")public class CustomerAction2 extends BaseAction<Customer> {    @Action(value="customer_sendSms")    public String sendSms() throws IOException{        //生成短信验证码        String randomCode = RandomStringUtils.randomNumeric(4);        //将短信验证码保存到session中        ServletActionContext.getRequest().getSession().setAttribute(model.getTelephone(),randomCode);        //编辑短信内容        String msg = "你好！本次获取的验证码位："+randomCode;        //调用SMS服务发送短信        String result = SmsUtils.sendSmsByHTTP(model.getTelephone(),msg);        if(result.startsWith("000")){            //以"000"开头表示短信发送成功            return NONE;        }else{            //发送失败，就抛出一个运行期异常            throw new RuntimeException("短信发送失败,信息码："+result);        }    }}

发短信的SmsUtils工具类完整代码如下：

/** * 调用吉信通 发短信工具类 *  * @author niwotaxuexiba * */public class SmsUtils {    private static String userid = "seawind";    private static String pass = "niwotaxuexiba123456";    /**     * 调用HTTP 协议方式发送短信     *      * @param mobile     * @param content     * @return     * @throws UnsupportedEncodingException     */    public static String sendSmsByHTTP(String mobile, String content)            throws UnsupportedEncodingException {        HttpURLConnection httpconn = null;        String result = "Error";        StringBuilder sb = new StringBuilder();        sb.append("http://service.winic.org:8009/sys_port/gateway/index.asp?");        // 以下是参数        sb.append("id=").append(URLEncoder.encode(userid, "gb2312"));        sb.append("&pwd=").append(pass);        sb.append("&to=").append(mobile);        sb.append("&content=").append(URLEncoder.encode(content, "gb2312"));        sb.append("&time=").append("");        try {            URL url = new URL(sb.toString());            httpconn = (HttpURLConnection) url.openConnection();            BufferedReader rd = new BufferedReader(new InputStreamReader(                    httpconn.getInputStream()));            result = rd.readLine();            rd.close();        } catch (MalformedURLException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        } finally {            if (httpconn != null) {                httpconn.disconnect();                httpconn = null;            }        }        return result;    }    /**     * 调用 WebService 协议方式发送短信     *      * @param mobiles     * @param msg     * @return     */    public static String sendSmsByWebService(String mobiles, String msg) {        String result = "-12";        try {            Document doc;            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();            dbf.setNamespaceAware(true);            DocumentBuilder db = dbf.newDocumentBuilder();            InputStream is = getSoapInputStream(userid, pass, mobiles, msg, "");            if (is != null) {                doc = db.parse(is);                NodeList nl = doc.getElementsByTagName("SendMessagesResult");                Node n = nl.item(0);                result = n.getFirstChild().getNodeValue();                is.close();            }            return result;        } catch (Exception e) {            System.out.print("SmsSoap.sendSms error:" + e.getMessage());            return "-12";        }    }    private static String getSoapSmssend(String userid, String pass,            String mobiles, String msg, String time) {        try {            String soap = "";
