1.给客户做一个发邮件的功能。收件人和抄送人可能为单个人，也可能为多个人。但是当收件人或抄送人中某一个邮箱的格式错误时，整个邮件发送就会出错停止发送。但我还需要给那些其余的人发邮件，该怎么办？ 2.解决思路，当收件人邮箱错误时，可以catch到异常，并从异常信息提取错误的邮箱，再把错误的邮箱从，收件人或抄送人中剔除，再次发送即可。 伪代码： try{ 发送邮件 }catch(Exception e){ if(判断是否为邮件发送错误异常){ 获取错误的邮件，并从收件人或抄送人中剔除 再次发送邮件 } }3.完整代码 @Override public void sendEmail(String main, String cc, IWorkItem weekly) throws Exception { List sendTo1 = new ArrayList(Arrays.asList(main.split(","))); List copyTo1 = new ArrayList(Arrays.asList(cc.split(","))); String mode = "client";//test / client try { // 创建一个配置文件并保存 Properties properties = new Properties(); if(mode.equals("test")) { properties.setProperty("mail.host", "smtp.qq.com");
