从mysql数据库中检索密码将发送到android中的电子邮件+；java Web服务

我已经开发了登录表单android应用程序。在这里，我必须实现忘记密码字段。如果我点击忘记密码

textview

，它将进入下一个活动

下一个活动将接收用户的电子邮件，并从调用soap

webservices

的mysql数据库检查其验证

我已经完成了上面的部分

现在我必须实现以下部分：

电子邮件有效意味着从mysql数据库获取密码并将这些密码发送到有效的电子邮件

如何在java Web服务代码中实现这一部分。请帮助我。给我一些解决方案

这是我的java webservice代码，用于检查电子邮件是否有效：

public class Checkemail {
public String authentication(String Email){

String retrievedUserName = "";

String status = "";
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/xcart-432pro","root","");
 PreparedStatement statement =  con.prepareStatement("SELECT * FROM xcart_customers WHERE email = '"+Email+"'");
 ResultSet result = statement.executeQuery();

 while(result.next()){
 retrievedUserName = result.getString("email");

 }

 if(retrievedUserName.equals(Email)){
 status = "Valid Email";
 }

 else{
  status = "Invalid Email!!!";
      }

      }
        catch(Exception e){
         e.printStackTrace();
         }
       return status;

          }

             }

这是我的android代码：

        public class Login extends Activity {
       private final String NAMESPACE = "http://xcart.com";
       private final String URL = "http://10.0.0.75:8080/XcartLogin/services/Checkemail?wsdl";
       private final String SOAP_ACTION = "http://xcart.com/authentication";
       private final String METHOD_NAME = "authentication";
       /** Called when the activity is first created. */
       @Override
       public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.login);
       Button login = (Button) findViewById(R.id.btn_login);
       login.setOnClickListener(new View.OnClickListener() {

       public void onClick(View arg0) {
         loginAction();
         }
         });
         }

      private void loginAction(){
       SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

             EditText Email = (EditText) findViewById(R.id.tf_userName);
            String email = Email.getText().toString();


             //Pass value for userName variable of the web service
          PropertyInfo unameProp =new PropertyInfo();
           unameProp.setName("Email");//Define the variable name in the web service method
         unameProp.setValue(email);//set value for userName variable
         unameProp.setType(String.class);//Define the type of the variable
         request.addProperty(unameProp);//Pass properties to the variable
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(request);
         HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
          try{
          androidHttpTransport.call(SOAP_ACTION, envelope);
           SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
           String status = response.toString();
           TextView result = (TextView) findViewById(R.id.tv_status);
           result.setText(response.toString());
             }
            catch(Exception e){

          }
          }
          }

如何实现在java webservice代码中获取发送到电子邮件的密码？

使用此代码。。这对你很有帮助

 import java.io.BufferedReader;
 import java.io.InputStreamReader;
 import java.net.Authenticator;
 import java.net.PasswordAuthentication;
 import java.net.URL;
 import java.net.URLConnection;
 import android.app.Activity;
 import android.os.Bundle;
 import android.util.Log;

  public class Connect extends Activity {
static StringBuilder sb;

   @Override
public void onCreate(Bundle savedInstanceState) {

     super.onCreate(savedInstanceState);
     setContentView(R.layout.main);

     String strURL = "http://hostserver/";
    final String username = "username";
    final String password = "password";
    Authenticator.setDefault(new Authenticator() {
          protected PasswordAuthentication getPasswordAuthentication() {
                PasswordAuthentication pa = new PasswordAuthentication  
                                     (username, password.toCharArray());
                System.out.println(pa.getUserName() + ":" + new 
                                      String(pa.getPassword()));
                return pa;
            }
          });
    BufferedReader in = null;
    StringBuffer sb = new StringBuffer();

    try {
        URL url = new URL(strURL);
        URLConnection connection = url.openConnection();
        in = new BufferedReader(new InputStreamReader(connection
                .getInputStream()));

        String line;

        while ((line = in.readLine()) != null) {
            sb.append(line);
        }
    } catch (java.net.ProtocolException e) {
        sb.append("User Or Password is wrong!");
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            if (in != null) {
                in.close();
            }
        } catch (Exception e) {
            System.out.println("Exception");
        }
    }

    Log.d("DATA", sb.toString());

}

使用此代码，它对您的帮助

  String email_id = etxt_user.getText().toString();
  SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
  request.addProperty("Email", email_id);
   Pattern EMAIL_ADDRESS_PATTERN =Pattern.compile(

    if(matcher.matches()){
     Log.v(TAG, "Your email id is valid ="+email_id);

    Log.v("TAG", String.valueOf(resultsRequestSOAP));
   } catch (Exception e) {

     e.printStackTrace();
  }

}

String email_id=etxt_user.getText（）.toString（）；
SoapObject请求=新的SoapObject（名称空间、方法名称）；
请求。添加属性（“电子邮件”，电子邮件id）；
模式电子邮件地址模式=模式编译(
“[a-zA-Z0-9\\+\.\\\\%\-\\+]{1256}”+

试一试{
aht.setXmlVersionTag（“”）；
aht.call（SOAP\u动作，soapEnvelope）；
SoapObject resultsRequestSOAP=（SoapObject）soapEnvelope.bodyIn；
Log.v（“TAG”，String.valueOf（resultsRequestSOAP））；
}捕获（例外e）{
e、 printStackTrace（）；
}
}

我必须在Web服务部分实现代码。我必须获取有效电子邮件的密码并发送到电子邮件。如果（retrievedUserName.equals（email））{status=“valid email”；在这些行之后如何获取密码我已经检查了电子邮件验证。如果电子邮件有效，则意味着如何获取密码并发送到电子邮件。如果有人忘记了密码，更好的解决方案是为他们创建一个新密码以覆盖以前的密码，而不是发送以前的密码
