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
mail.account=wenbinandy@gmail.commail.password=*******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>
