Java Web development 4: Implementation of email sending and SMS sending, java SMS sending

Email sending and text message sending are common in user registration and authentication and system message prompting modules, but the implementation code is too cumbersome. After JSPGen is used, the encapsulation of emails and text messages makes complex activities much easier.

In the SMS sending module, two methods are supported: third-party sending and local platform sending, here we mainly demonstrate the configuration and implementation of third-party sending methods (you do not need to configure the sending method when using the local platform, and rewrite the corresponding implementation class according to the SMS sending interface file ).

I. basic configuration

Jspgen-config.xml
In the basic configuration file of the Framework, locate the mail node and sms node, and configure as follows:

<! -- Mail service --> <mail status = "true"> <smtp> <! -- Sending type (smtp mx) --> <type> SMTP </type> <server> smtp.163.com </server> <port> 25 </port> <email> jspgen@163.com </email> <name> JSPGen official website </name> <username> jspgen </username> <password> jspgen </password> <! -- Content format (text html url) --> <format> html </format> <! -- Content signature --> <sign> JSPGen-makes Java (Web) software development more agile! Www.JSPGen.com </sign> </smtp> </mail> <! -- Sms Service (http) --> <sms status = "true"> <! -- Submit address and method (get post) --> <url> Sending address </url> <method> GET </method> <charset> UTF-8 </charset> <username> <key> name </key> <value> jspgen </value> </username> <password> <key> password </key> <value> jspgen </value> </password> <! -- Whether batch Sending is supported --> <mobile batch = "false"> <key> mobile </key> <gap>; </gap> </mobile> <content> <key> msg </key> </content> <time> <key> dtime </key> <! -- Time format. If it is null, it is a Long timestamp. --> <format> yyyy-MM-dd HH: mm: ss </format> </time> <! -- Return data --> <return> <! -- Return format (text xml json) --> <format> text </format> <! -- Return keyword, which is useful when the format is xml/json --> <key> status </key> <! -- Return success id --> <value> 0 </value> </return> <! -- Content signature --> <sign> [JSPGen] </sign> </sms>

 

Ii. Code Implementation

1. SendAction. java

"); Return SUCCESS;}/*** send sms submission */public String sms () {boolean isflag = false; Long time = Dates. getTimeMillis (); String to = getParameter ("to"); // receives the form value (form name: to) isflag = sendSMS (to, getParameter ("content "), time); // if (! Isflag) {addActionError ("failed to send! "); Return ERROR;} addActionMessage (" sent successfully! "); Return SUCCESS ;}}

 

2、mail.html portal page template

<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
 
Iii. Test
Enter http: // localhost: 8080/jspgensdf/send. gen in the browser.

 
Note:163 the newly registered account cannot be sent. It seems that it takes two months to use it. You can build an email service environment and test it.
 
 
 

Java Web development email sending and user verification
Each user record defines whether there are only two conditions for marking a and. By default, whether a user's initial a mark is used. After the user clicks "Verification Successful", change "a = No" to "a = yes ".

How does java web implement email sending or communication in its own system?
If it is for common sending and receiving messages, you can simply check the database.
If you want to do mail, you need to have a mail server, and then use the SMTP and POP3 protocols for sending and receiving operations.
For instant messaging, You can dive into the socket program on the page, or perform real-time Dynamic Refresh, ajax
