今天学习了一下JavaMail,javamail发送邮件确实是一个比较麻烦的问题。为了以后使用方便,自己写了段代码,打成jar包,以方便以后使用。呵呵
以下三段代码是我的全部代码,朋友们如果想用,直接复制即可。
第一个类:MailSenderInfo.java

最后,给出朋友们几个注意的地方:
1、使用此代码你可以完成你的javamail的邮件发送功能。三个类缺一不可。
2、这三个类我打包是用的com.util.mail包,如果不喜欢,你可以自己改,但三个类文件必须在同一个包中
3、不要使用你刚刚注册过的邮箱在程序中发邮件,如果你的163邮箱是刚注册不久,那你就不要使用“smtp.163.com”。因为你发不出去。刚注册的邮箱是不会给你这种权限的,也就是你不能通过验证。要使用你经常用的邮箱,而且时间比较长的。
4、另一个问题就是mailInfo.setMailServerHost("smtp.163.com");与mailInfo.setFromAddress("han2000lei@163.com");这两句话。即如果你使用163smtp服务器,那么发送邮件地址就必须用163的邮箱,如果不的话,是不会发送成功的。
5、关于javamail验证错误的问题,网上的解释有很多,但我看见的只有一个。就是我的第三个类。你只要复制全了代码,我想是不会有问题的。
