因为工作需要发送邮件。所以上网找了例子，整理了一下发表出来，方便有需要的朋友。

封装邮件信息的一个实体类。

package com.base.myproject.mail;

import java.util.ArrayList;
import java.util.List;
import java.util.Properties;

public class MailSenderInfo {
	
     public static String TEXT = "text/plain;charset=gb2312";
     public static String HTML = "text/html;charset=gb2312";
	
    private String mailServerHost;                // 发送邮件的服务器的IP和端口   
    private String mailServerPort = "25";         
    
    private String fromAddress;                   // 邮件发送者的地址
    private String toAddress;                     // 邮件接收者的地址   
      
    private String userName;   
    private String password;                      // 登陆邮件发送服务器的用户名和密码 
    
    private boolean validate = false;             // 是否需要身份验证   
      
    private String subject;                       // 邮件主题 
    private String content;                       // 邮件的文本内容
    private List<Object> attaches = new ArrayList<Object>();						 //邮件附件;             
    
    private String cc;                           //抄送邮件给某人
    private String bc;                           //隐蔽副本 隐蔽抄送给某人
    
    /**

      */   
    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 boolean isValidate() {   
      return validate;   
    }  
    public void setValidate(boolean validate) {   
      this.validate = validate;   
    }

    }  
    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 List<Object> getAttaches() {

	public String getBc() {
		return bc;
	}
	public void setBc(String bc) {

	}  
    
    
}

邮件用户名密码认证

package com.base.myproject.mail;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class MyAuthenticator extends Authenticator{

    String userName = null;  
    String password = null;  
       
    public MyAuthenticator(){  
    	
    }  
    public MyAuthenticator(String username, String password) {   
        this.userName = username;   
        this.password = password;   
    }   
    protected PasswordAuthentication getPasswordAuthentication(){  
        return new PasswordAuthentication(userName, password);  
    }  
}
