3.身份认证
Java代码

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

package com.mail;

import javax.mail.*;

public class MyAuthenticator extends Authenticator {
private String username = "";
private String password = "";

public MyAuthenticator() {
}

public MyAuthenticator(String username, String password) {
this.username = username;
this.password = password;
}

protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}

}


4.测试使用
Java代码
package com.mail;  
 
public class TestMail {  
      
    public static void main(String[] args) {  
        MailInfo mailinfo=new MailInfo();  
        //--设置邮件服务器开始  
        mailinfo.setMailServerHost("smtp.gmail.com");  
        mailinfo.setMailServerPort("465");  
        mailinfo.setValidate(true);  
        mailinfo.setUserName("zhaozhi3758");  
        mailinfo.setPassword("XXXXXXXX");  
        //--设置邮件服务器结束  
        mailinfo.setFromAddress("[e-mail]");//邮件发送者的地址  
        //设置接受用户  
        String []ToAddress={"[e-mail]"};  
        mailinfo.setToAddress(ToAddress);  
        //设置附件  
        String []attach={"F:\\login.properties"};  
        mailinfo.setAttachFileNames(attach);  
        mailinfo.setSubject("-----邮件测试----");  
        mailinfo.setContent("<a href='#'>hiao的和</a>");//网页内容  
        SendMail sm=new SendMail();  
        if(sm.sendAttach(mailinfo))  
            System.out.println("邮件发送成功");  
        else 
            System.out.println("邮件发送失败");  
          
    }  
 
}
