2. A tool class that encrypts strings through MD5:

Class= "Java" >import java.io.unsupportedencodingexception;import Java.security.messagedigest;import java.security.nosuchalgorithmexception;/** * Created by: Zy * Created: October 22, 2014 2:36:19 * Class Description: A tool class that encrypts a string */public class Md5ut   Il {/** * encrypts the source string through MD5 to a byte array * @param source * @return */public static byte[] Encodetobytes (string source) {byte[] Result = null;try {MessageDigest MD = messagedigest.getinstance ("MD5"); Md.reset ();//Reset Md.update (Source.getbytes ("UTF-8")) ;//Add source that needs to be encrypted result = Md.digest ();//encryption} catch (NoSuchAlgorithmException e) {e.printstacktrace ();} catch ( Unsupportedencodingexception e) {e.printstacktrace ();} return result;} /** * Encrypts the source string to a 32-bit 16 binary number by MD5 * @param source * @return */public static string Encodetohex (string source) {byte[] data = ENC Odetobytes (source);//first encrypted as byte array stringbuffer hexsb = new StringBuffer (); for (int i = 0; i < data.length; i++) {String hex = Integer.tohexstring (0xFF & Data[i]); if (hex.length () = = 1) {hexsb.append ("0");} Hexsb.append (hex);} Return HEXSB.TOSTRing ();} /** * Verify string matches * @param unknown string to be validated * @param okhex using MD5 encrypted 16 binary string * @return */public static Boolean validate (String u Nknown, String Okhex) {return okhex.equals (Encodetohex (unknown));}}

3. The tool class for sending mail:

User user = Userdao.getuser (); if (user! = null && USER.GETQYBJ ()! = 1) {String email = user.getemail ();  StringBuffer content = new StringBuffer ("

5. Click the link to verify the servlet or action:
String userName = request.getparameter ("name"); String email = request.getparameter ("email"); Userpostdao Userdao = new Userpostdao (); User user = Userdao.getuserbyemail (email), if (user = = null) {destination = "/register/activefail.jsp"; Request.setattribute ("msg", "link Error");} else {String userNameMd5 = Md5util.encodetohex (user.getusername () + "Audit Pass"); Username.equals (USERNAMEMD5)) {Request.setattribute ("msg", "link Error");d estination = "/register/activefail.jsp";} else {Boolean done = Userdao.updateuserstatusbyemail (e-mail, 1), if (done) {Request.setattribute ("UserId", User.getuserid ()); Request.setattribute ("UserName", User.getusername ());d estination = "/register/activesuccess.jsp ";} else {Request.setattribute ("msg", "Activation Error");d estination = "/register/activefail.jsp";}}}
