Java SPRINGMVC Mail sending configuration and code

The first is the configuration in spring: (I used the freemarker template engine)

<!--mail delivery implementation class-->    <bean id= "Javamailsender"  class= " Org.springframework.mail.javamail.JavaMailSenderImpl ">        < Property name= "Host"  value= "smtp.qq.com"/>        < Property name= "Port"  value= "/>        <property"  name= "username"  value= "Your Mailbox"/>        <property  Name= "Password"  value= "Your mailbox password"/>        <property name = "Javamailproperties" >            <props  >                < prop key= "Mail.smtp.auth" >true</prop>             </props>        </property>    </bean>     <bean id= "Simplemailmessage"  class= "Org.springframework.mail.SimpleMailMessage" >         <property name= "from"  value= "sender"  />         <property name= "Subject"  value= "Mail Subject"  />         <!--        <property  name= "text"  value= "Mail Content"  />        -->     </bean> <!--thread pool asynchronously sends mail-->    <bean id= " Taskexecutor " class=" Org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor ">         <property name= "Corepoolsize"  value= "5"  />         <p roperty name= "Maxpoolsize"  value= "ten"  />         <property name= "queuecapacity"  value= " />    </bean> "    <!--freemarker Template-->    <bean id= "Freemarkerconfigurer"  class= "Org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer" >         <property name= "Templateloaderpath"  value= "Classpath:template"  />         <!--<property name= "Templateloaderpath"  value= "/template"  />-->        <property name= " Freemarkersettings ">            <props>                 <prop  key= "Locale" >zh_cn</prop>                <prop  key= "Default_encoding" >UTF-8</prop>             </props>        </property>     </bean>

Tool classes for sending messages: (using annotations as a class for managing mail delivery)

public class mailsender {     @Inject     private  javamailsender javamailsender;     @Inject     private  simplemailmessage simplemailmessage;     @Inject     private  freemarkerconfigurer freemarkerconfigurer;     @Inject     private  TaskExecutor taskExecutor;    /**     *  Build mail content, Send the message.      *  @param  user   users      *  @param  url    links      */    public void  Send (User user, string url,string email)  {         string nickname = user.getnickname ();         string to = email;        string text =  "";         map<string, string> map = new hashmap<string,  String> (1);         map.put ("url",  url);         try {//              generate message content from Freemarker templates              Template template = freemarkerconfigurer.getconfiguration (). GetTemplate ("REGISTER_MAIL.FTL");//              template with ${xxx}, the value of key XXX in map replaces placeholder content.             text =  Freemarkertemplateutils.processtemplateintostring (Template, map);         } catch  (ioexception e) &nbsP {            e.printstacktrace ();         } catch  (templateexception e)  {             e.printstacktrace ();         }        this.taskexecutor.execute (New SendMailThread (To,null,text));     }    //     internal threading class that asynchronously sends messages using the thread pool.     private class SendMailThread implements Runnable {         private String to;         private String subject;        private  String content;        private sendmailthread (String to , string subject, string content)  {            super ();             this.to = to;             this.subject = subject;             this.content = content;         }         @Override          public void run ()  {             sendmail (to, subject, content);         }    }    /**     *  Send mail      *  @param  to         recipient mailbox      *  @param subject    Mail subject      *  @param  content     e-mail content      */    public void sendmail (String  To, string subject, string content)  {         Try {            mimemessage message  = javamailsender.createmimemessage ();             mimemessagehelper messagehelper = new mimemessagehelper (Message, true,   "UTF-8");             messagehelper.setfrom ( Simplemailmessage.getfrom ());            if  ( Subject != null)  {                 messageHelper.setsubject (subject);             } else  {                 Messagehelper.setsubject (Simplemailmessage.getsubject ());             }             Messagehelper.setto (To);             Messagehelper.settext (content, true);            Javamailsender.send (message);        } catch  ( Messagingexception e)  {             E.printstacktrace ();         }    }}

Service Layer Invocation:

1. To inject the Send mail tool class

@Inject private MailSender MailSender;

2. Calling code

User user = (user) request.getsession (). getattribute ("user"); String URL = request.getscheme () + "://" +request.getservername () + ":" +request.getserverport () + Request.getcont        Extpath (); Mailsender.send (User,url,email);
