dwr实现找回密码的功能

需求：用户根据自己注册的账号、邮箱实现可以找回密码的功能。
实现：就是根据正确的账号、邮箱，实现自动发邮件的功能。

下面看我的实现过程：

先看两个配置文件：
1.db.properties

database.driver_class=oracle.jdbc.driver.OracleDriverdatabase.url=jdbc:oracle:thin:@webnet:1521:orcldatabase.username=baseextdatabase.password=11

2.mail.properties

[email protected]=*******mail.host=smtp.gmail.com

DAO层UnionUsersDAO查询数据库得到密码

public String getPassword(String account,String email) throws Exception{    InputStream inputStream =this.getClass().getClassLoader().getResourceAsStream("db.properties");        Properties p = new Properties();    try {    p.load(inputStream);    inputStream.close();} catch (IOException e1) {        e1.printStackTrace();    }       String drivers= p.getProperty("database.driver_class");String url= p.getProperty("database.url");String user= p.getProperty("database.username");String password = p.getProperty("database.password");    Connection conn = null;    Statement stat = null;    ResultSet rs = null;    String passWord = "";    try{        Class.forName(drivers);conn = DriverManager.getConnection(url, user, password);stat = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,                     ResultSet.CONCUR_READ_ONLY);String sql = "select c_password from union_users where c_account='"+account+"' and c_email ='"+email+"'";rs = stat.executeQuery(sql);while(rs.next()){passWord = rs.getString(1);}     }catch(Exception e){          e.printStackTrace();     }finally{ if(rs!=null){rs.close();rs=null;     }         if(stat!=null){stat.close();stat=null; } if(conn!=null){conn.close();conn=null; }     }     return passWord;} 

Service层UnionUsersServiceImpl

public String getPassword(String account, String email){try {return this.getUnionUsersDao().getPassword(account, email);} catch (Exception e) {e.printStackTrace();}return "";}

applicationContext.xml中相关配置

         <!--  dao 注入--><bean id="UnionUsersDAO" class="com.ao.dao.UnionUsersDAO"><property name="sessionFactory"><ref bean="sessionFactory" /></property></bean>         <!--  service 注入--><bean id="unionUsersService"class="com.ao.service.impl.UnionUsersServiceImpl"><property name="unionUsersDao"><ref bean="UnionUsersDAO" /></property></bean>

dwr.xml中的配置

       <create creator="spring" javascript="UsersService" scope="application">      <param name="beanName" value="unionUsersService" />        </create>        <create creator="new" javascript="SendMail" scope="application">      <param name="class" value="com.ao.web.util.SendMail" />        </create>

getPassword.jsp中调用
