毕设第二天

好久没有完整的程序了，上个完整的还是去年7月份，因为备战考研也没有学习新技术。
今天把登陆 注册 找回密码的后台程序完成了。利用阿里云的短信发送机制，拦截器等功能。

短信机制

package com.lzm.utils;

import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
import org.springframework.stereotype.Controller;

/*
pom.xml
<dependency>
  <groupId>com.aliyun</groupId>
  <artifactId>aliyun-java-sdk-core</artifactId>
  <version>4.0.3</version>
</dependency>
*/
@Controller
public class SendSms {

    public String PhoneMsg(String phone) {
        DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "LTAIP9rsh3YQnp4V", "EqazTiOwQlDz2T2BvTVEeLuXrywk8V");
        IAcsClient client = new DefaultAcsClient(profile);

        CommonRequest request = new CommonRequest();
        request.setMethod(MethodType.POST);
        request.setDomain("dysmsapi.aliyuncs.com");
        request.setVersion("2017-05-25");
        request.setAction("SendSms");
        request.putQueryParameter("PhoneNumbers", phone);
        request.putQueryParameter("SignName", "懒虫笔记");
        request.putQueryParameter("TemplateCode", "SMS_170347395");
        String s = vcode();
        request.putQueryParameter("TemplateParam", "{\"code\":\""+s+"\"}");
        try {
            CommonResponse response = client.getCommonResponse(request);
            System.out.println(response.getData());
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
        return s;
    }


    /**
     * 生成6位随机数验证码
     * @return
     */
    public static String vcode(){
        String vcode = "";
        for (int i = 0; i < 6; i++) {
            vcode = vcode + (int)(Math.random() * 9);
        }
        return vcode;
    }

}

拦截器

package com.lzm.interceptor;


import com.lzm.pojo.UserInfo;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

public class Interceptor1 implements HandlerInterceptor{

	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object arg2) throws Exception {
		// TODO Auto-generated method stub
		HttpSession session = request.getSession();
		String requestURI = request.getRequestURI();
		//如何实现一个字符串是否包含数组中的任一元素
		if(!requestURI.contains("Login") ){
			UserInfo user = (UserInfo) session.getAttribute("user");
			if (null == user) {
//	/没有登陆，转向登陆界面
				request.getRequestDispatcher("/ToLogin.action").forward(request,response);
				return false;
			}
		}
		return true;
	}

	public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3)
			throws Exception {
		// TODO Auto-generated method stub
		System.out.println("方法后 1");
		
	}
	public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3)
			throws Exception {
		// TODO Auto-generated method stub
		System.out.println("页面渲染后 1");
		
	}



}

拦截器需要在springmvc配置

		<!--&lt;!&ndash;SpringMVC拦截器&ndash;&gt;-->
<!--&lt;!&ndash;-->
			<!--&lt;!&ndash; 多个拦截器 &ndash;&gt;-->
	<!--<mvc:interceptors>-->
			<!--<mvc:interceptor>-->
				<!--<mvc:mapping path="/*.action"/>-->
				<!--&lt;!&ndash;&lt;!&ndash; 自定义的拦截器类 &ndash;&gt;&ndash;&gt;-->
				<!--<bean class="com.lzm.interceptor.Interceptor1"/>-->
			<!--</mvc:interceptor>-->
	<!--</mvc:interceptors>-->

感觉内容挺多的，明天把用户管理做了，一个一个来吧。
