Java Mail Tool class

The mail entity is encapsulated first, and the protocol uses SMTP:

import java.util.list;import javax.mail.internet.internetaddress;/** *  Mailbox Entity class  * @ author administrator * */public class emailinfo {//  mailbox The address of the server that corresponds to SMTP is private  String smtpHost;//  e-Mail user name private string user;private string password;//   Message Subject private string subject;//  message content (you can insert HTML tags in a string) private string content;//   Encoding of message content (default nullable) private string charset =  "Text/html;charset=utf-8";//  The address of the object that receives the e-mail address of the private list<internetaddress> receiveemailaddress;//  cc message private  List<internetaddress> ccemailaddress;public emailinfo ()  {super ();} Public emailinfo (string smtphost, string user, string password, string  subject, string content, list<internetaddress> receiveemailaddress)  { Super (); THIS.SMTPHOST&NBSP;=&NBSP;SMTPHOST;THIS.USER&NBSP;=&Nbsp;user;this.password = password;this.subject = subject;this.content = content; this.receiveemailaddress = receiveemailaddress;} Public string getsmtphost ()  {return smtphost;} Public void setsmtphost (String smtphost)  {this.smtphost = smtphost;} Public string getuser ()  {return user;} Public void setuser (String user)  {this.user = user;} Public string getpassword ()  {return password;} Public void setpassword (String password)  {this.password = password;} Public string getsubject ()  {return subject;} Public void setsubject (String subject)  {this.subject = subject;} Public string getcontent ()  {return content;} Public void setcontent (string content)  {this.content = content;} Public list<internetaddress> getReceiveemailaddress ()  {return receiveemailaddress;} Public void setreceiveemailaddress (list<internetaddress> receiveemailaddress)  { this.receiveemailaddress = receiveemailaddress;} Public string getcharset ()  {return charset;} Public void setcharset (String charset)  {this.charset = charset;} Public list<internetaddress> getccemailaddress ()  {return ccemailaddress;} Public void setccemailaddress (list<internetaddress> ccemailaddress)  { this.ccemailaddress = ccemailaddress;}}
