闲来没事研究了一下javamail发邮件。虽然比Spring框架的mail复杂一些,但是还是值得研究一下的。
mail.jar和本程序的jar包都会在附件中上传,供大家使用学习。
第一个类,用于密码验证,注意看注释,很重要。

package com.xian.gmail;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
/**
* JavaMail的密码验证器
* @author 贾小仙
*/ public class MyAuther extends Authenticator{
String userName= null ;
String password= null ;
public MyAuther() {
}
public MyAuther(String userName, String password) {
this .userName = userName;
this .password = password;
}
//getPasswordAuthentication 名字必须对。 源码中是return null。相当于重写
protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(userName,password);
}
} |
第二个类是实体类,做一些基本参数处理
