翻了很多资料，研究了一段时间，终于实现了功能
首先，我们发邮件需要有邮件的信息，写一个类来封装邮件的内容和主题：
/**
* 主要用来封装所要发送的邮件信息
* @author Administrator
*
*/
public class SimpleMail {
//邮件中的主题
private String subject;
//邮件的内容（正文）
private String content;
//可根据需要增加其他邮件元素
public void setSubject(String subject) {
this.subject = subject;
}
public void setContent(String content) {
this.content = content;
}
public String getSubject() {
return subject;
}
public String getContent() {
return content;
}
}有了邮件的信息，我们就要有邮箱的登陆账号密码，然后进行验证：
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
/**
* 服务器邮箱登录验证
*/
public class MailAuthenticator extends Authenticator {
// 用户名（登录邮箱）
private String username;
// 密码
private String password;
/**
* 初始化邮箱和密码
* @param username 邮箱
* @param password 密码
*/
public MailAuthenticator(String username, String password){
this.username = username;
this.password = password;
}
String getPassword() {
return password;
}
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
String getUsername() {
return username;
}
public void setPassword(String password) {
this.password = password;
}
public void setUsername(String username) {
this.username = username;
}
}之后我们需要判断属于那种邮箱，是126的、还是163的、或者其他的
public class Const {
public final static String FROMEMAIL = "organisms_master@126.com";
public final static String FROMEMAIL_PASSWORD = "master";
public static String WEB_SITE="localhost:8080";
public static String PROJECT="organisms-master";
public static String returnEmailWeb(String email) {
String str = null;
if (email.indexOf("@qq.com") != -1) {
// qq邮箱
return "https://mail.qq.com/";
}
if (email.indexOf("@126.com") != -1) {
// 126
return "http://www.126.com";
}
if (email.indexOf("@hotmail.com") != -1) {
// hotmail
return "http://www.hotmail.com";
}
if (email.indexOf("@163.com") != -1 || email.indexOf("@yeah.net") != -1) {
// 163 yeah
return "http://email.163.com/";
}
if (email.indexOf("@yahoo.com.cn") != -1
|| email.indexOf("@yahoo.cn") != -1) {
// yahoo
return "http://mail.cn.yahoo.com/";
}
if (email.indexOf("@sina.com") != -1
|| email.indexOf("@vip.sina.com") != -1) {
// sina
return "http://mail.sina.com.cn/";
}
if (email.indexOf("@gmail.com") != -1) {
// gmail
return "http://mail.google.com";
}
if (email.indexOf("@139.com") != -1) {
return "http://mail.10086.cn/";
}
if (email.indexOf("@sohu.com") != -1) {
return "http://mail.sohu.com/";
}
return str;
}
public static void main(String[] args) {
System.out.println(returnEmailWeb("664659008@qq.com"));
System.out.println(returnEmailWeb("angel__6386@126.com"));
System.out.println(returnEmailWeb("mrzhangl@hotmail.com"));
System.out.println(returnEmailWeb("name@163.com"));
}
}最后要发送邮件我们需要，邮件发送器，里面的注释非常清楚:
/**
* 此类实现邮件的单发、群发等等，是邮件发送的核心类
* @author Administrator

希望对你们有帮助！！！
