　　3. 调用java 类

?

1 2 3 4 5 6 7 8 9 10

try {     //添加成功，发送邮件通知     SendEmail email = new SendEmail();     email.sendEmail(Configs.senderQQ, Configs.senderQQAuthorizationCode, Configs.recipientQQMail, Configs.CcListQQMail, Configs.mailTitle,station_name,station_code);       cmdRes = ConstantUtil.CMD_RES_SUCCESS;     resFailReason = newMap.get("failreason").toString(); } catch (Exception e) {     cmdRes = ConstantUtil.CMD_RES_FAIL;     resFailReason = "添加成功，邮件通知失败，请联系相关人员，手动发送邮件通知第三方！"; }

　　4. 配置变量

?

1 2 3 4 5

public static final String senderQQ = "******";                     　　//发件人的QQ号 public static final String senderQQAuthorizationCode = "**********";        　　　　　　 //发件人的QQ授权码， public static final String recipientQQMail = "*****@yeah.net";                 //收件人的QQ邮箱 public static final String CcListQQMail = "******@qq.com";                  　　//抄送人的QQ邮箱 public static final String mailTitle = "关于 引、泄水流量数据接入";                //发送邮件主题

　　5. 关于发件人的QQ授权码获取步骤

　　qq邮箱授权码获取：登录QQ邮箱 → 设置 → 账户 → 找到IMAP/SMTP服务，点击开启 ，开启后会获取一个授权码
