spring发QQ邮件

一、今天做发邮件功能测试一直报： authentication failed 的错误。搜索了下资料才知道，一般的企业内部邮箱不需要认证，但是QQ的已经需要认证才能用。原来好像QQ邮件不需要认证，所以网上很多资料都不行。然后多方找资料后找到个，分享出来。具体步骤如下

 写个简单的main发邮件，代码如下

package test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;

public class Email {

    public void send(ApplicationContext ctx) {
        JavaMailSender sender = (JavaMailSender) ctx.getBean("javaMailSender");
        SimpleMailMessage mail = new SimpleMailMessage(); 
        try {
            mail.setTo("[e-mail]");// 接受者
            mail.setFrom("[e-mail]");// 发送者,
            mail.setSubject("测试主题");// 主题
            mail.setText("发送邮件内容测试");// 邮件内容
            sender.send(mail);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        ApplicationContext ctx = new ClassPathXmlApplicationContext(
                "spring-servlet.xml");
        Email e = new Email();
        e.send(ctx);
    }
}

spring-servlet.xml配置文件（红色部分为邮件发送配置有关的东西）
