Java mail (with attachments) supports SSL and ssl

Java mail has three types of email sending (with attachments ):

MailSenderInfo. java

Package mail; import java. util. properties; import java. util. vector; public class MailSenderInfo {// IP address and port of the server sending the mail private String mailServerHost; private String mailServerPort = "25"; // private String fromAddress; // The email recipient's address: private String toAddress; // the userName and password used to log on to the email sending server: private String userName; private String password; // whether authentication is required: private boolean validate = false; // whether to enable ssl private boole An validateSSL = false; // Email subject private String subject; // The text content of the email private String content; // the file name of the email attachment private Vector attachFileNames; /*** get mail session Properties */public Properties getProperties () {Properties p = new Properties (); p. put ("mail. smtp. host ", this. mailServerHost); p. put ("mail. smtp. port ", this. mailServerPort); p. put ("mail. smtp. auth ", validate? "True": "false"); return p;} public String getMailServerHost () {return mailServerHost;} public void setMailServerHost (String mailServerHost) {this. mailServerHost = mailServerHost;} public String getMailServerPort () {return mailServerPort;} public void setMailServerPort (String mailServerPort) {this. mailServerPort = mailServerPort;} public boolean isValidate () {return validate;} public void setValidate (boolean validate) {this. validate = validate;} public Vector getAttachFileNames () {return attachFileNames;} public void setAttachFileNames (Vector attachFileNames) {this. attachFileNames = attachFileNames;} public String getFromAddress () {return fromAddress;} public void setFromAddress (String fromAddress) {this. fromAddress = fromAddress;} public String getPassword () {return password;} public void setPassword (String password) {this. password = password;} public String getToAddress () {return toAddress;} public void setToAddress (String toAddress) {this. toAddress = toAddress;} public String getUserName () {return userName;} public void setUserName (String userName) {this. userName = userName;} public String getSubject () {return subject;} public void setSubject (String subject) {this. subject = subject;} public String getContent () {return content;} public void setContent (String textContent) {this. content = textContent;} public boolean isValidateSSL () {return validateSSL;} public void setValidateSSL (boolean validateSSL) {this. validateSSL = validateSSL ;}}

MailAuthenticator. java

package mail;import javax.mail.*;public class MailAuthenticator extends Authenticator {private String userName;private String password;public MailAuthenticator() {}public MailAuthenticator(String username, String password) {this.userName = username;this.password = password;}protected PasswordAuthentication getPasswordAuthentication() {return new PasswordAuthentication(userName, password);}}

SimpleMailSender. java

Test class

Package mail; import java. util. vector; public class MailTest {/*** @ param args */public static void main (String [] args) {// This class is mainly used to set MailSenderInfo mailInfo = new MailSenderInfo (); mailInfo. setMailServerHost (host); mailInfo. setMailServerPort ("465"); mailInfo. setValidate (true); mailInfo. setValidateSSL (true); mailInfo. setUserName ("username"); mailInfo. setPassword ("pwd"); // your email password mailInfo. setFromAddr Ess ("address"); mailInfo. setToAddress ("XXXXX@sina.cn"); mailInfo. setSubject ("set email title"); mailInfo. setContent ("today should be the day of meizu powder!

How can I implement an attachment when a java mail sends an email?

Java mail sends a program with a nearby component. You can search for an example.

This is not uploaded to the email server. It is included in the email when the email is sent,
What you can see in the webpage mailbox is to use the background program to parse the email, extract the file and put it on the server for download.

I have an available one here. It is also from the network and can be tested ..
