代码如下
SimpleMailMessage simple=new SimpleMailMessage();
mailSender.setHost("smtp.qq.com");
mailSender.setUsername("544645352@qq.com");
mailSender.setPassword("19890126520zhi");
System.out.println(mailSender.getHost());
System.out.println(mailSender.getUsername());
System.out.println(mailSender.getPassword());
simple.setTo("475376081@qq.com"); //设置收件人
simple.setCc("398974002@qq.com"); //设置抄送
simple.setBcc("373197082@qq.com"); //设置暗送
simple.setFrom("544645352@qq.com"); //设置发件人
simple.setSubject(this.getZhuti());//设置主题
simple.setText(this.getNeirong()); //设置内容
System.out.println(this.getZhuti());
System.out.println(this.getNeirong());
mailSender.send(simple); //使用邮件发送器 发送
错误如下：

点这个进去看看，
感觉
simple.setSubject(this.getZhuti());//设置主题
simple.setText(this.getNeirong()); //设置内容
可能是这两句中取到的内容为空。
