本文提供了一套完整的Java邮件发送解决方案，包括基本的邮件信息配置类`MailSenderInfo`、认证信息类`MyAuthenticator`及邮件发送实现类`SimpleMailSender`。通过这些类，用户可以轻松地发送纯文本或HTML格式的邮件。

发送邮件需要的源码如下

MailSenderInfo.java

/**   
* 发送邮件需要使用的基本信息 
*
*/    
import java.util.Properties;    
public class MailSenderInfo {    
    // 发送邮件的服务器的IP和端口    
    private String mailServerHost;    
    private String mailServerPort = "25";    
    // 邮件发送者的地址    
    private String fromAddress;    
    // 邮件接收者的地址    
    private String toAddress;    
    // 登陆邮件发送服务器的用户名和密码    
    private String userName;    
    private String password;    
    // 是否需要身份验证    
    private boolean validate = false;    
    // 邮件主题    
    private String subject;    
    // 邮件的文本内容    
    private String content;    
    // 邮件附件的文件名    
    private String[] attachFileNames;      
    /**

	         sms.sendHtmlMail(mailInfo);//发送html格式

注意：

需要把myeclipse安装目录下MyEclipse\Common\plugins\com.genuitec.eclipse.j2eedt.core_10.5.0.me201207171805\data\libraryset\EE_5的

javaee.jar右击用压缩文件打开javax文件夹下的activation和mail文件夹或jar删掉，记得把javaee.jar备份以防myeclipse崩溃。

再把下面的两个jar包添加到类库里面
