邮件发送方法类

package com.baidu;

import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

import javax.mail.internet.MimeMessage;

import org.springframework.mail.MailException;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.javamail.MimeMessageHelper;

import com.baidu.contans.Contans;


public class SendMailUtil {

    private static Properties propMail = new Properties();
    static{
        InputStream inputStream = null;
        try {
             inputStream = SendMailUtil.class.getResourceAsStream("/config_mail.properties");
             propMail.load(inputStream);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }finally{
            try {
                inputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        
    }
    
    public static String send(String toMailUserName,String subject,String content) throws Exception {

        JavaMailSenderImpl ms = new JavaMailSenderImpl();
        ms.setJavaMailProperties(propMail);
        String host = propMail.getProperty("host");
        
        ms.setHost(host);
        String protocol = propMail.getProperty("protocol");
        ms.setProtocol(protocol);
        ms.setPort(25);
        String mail_username = propMail.getProperty("mail_username");
        String mail_password = propMail.getProperty("mail_password");
        ms.setUsername(mail_username);
        ms.setPassword(mail_password);
         MimeMessage mailMessage = ms.createMimeMessage();  
         MimeMessageHelper mail = new MimeMessageHelper(mailMessage,true,"utf-8");
        mail.setFrom(mail_username);
        mail.setSubject(subject);
        mail.setTo(toMailUserName);
        mail.setText(content,true);
        try {
            ms.send(mailMessage);
            return Contans.MAIL_SUCC;
        } catch (MailException e) {
            e.printStackTrace();
            return Contans.MAIL_ERROR;
        }
    }
}




package com.baidu.contans;

public class Contans {

    public static final String MAIL_SUCC = "SUCCESS";
    public static final String MAIL_ERROR = "ERROR";
}



Main方法测试

package demo;

import com.baidu.SendMailUtil;

public class SingleMailSend {

    public static void main(String args[]) throws Exception {
        String mail="发送目标邮箱";
        String subject="。。。。。。。。。。。";
        String content="。。。。。。。。";
        String send = SendMailUtil.send(mail, subject, content);
        System.out.println(send);
    }
}
