我用JAVAMAIL作了个收邮件和发邮件的程序,单独调试都成功了,但是我用自己的程序发邮件时,收邮件收不到发的,其他邮箱(例如163发来的就收的到),反正就是这两个程序不能合着用,经过我调试发现是这句话抛的异常:
我不考虑附件情况

我发邮件时设置内容并没有什么特别的,主题到是处理了下,程序中过滤器用的是GB2312,为什么啊,我郁闷啊,大家帮忙啊???
------解决方案--------------------
java.io.IOException: Unknown encoding: Gbk
这句IO异常，你看看是不是哪里用了Gbk？
------解决方案--------------------
收到的邮件格式为GBK。javamail不能解析，所以出这个异常。具体的我也说不好，找找相关的资料吧。我也是现学现卖。
