此代碼用的jar文件：mail.jar(我這里用的是1.4.7 的版本);
如果jdk用的是1.8版本會出現(xiàn)SSL錯誤：這個問題是jdk導(dǎo)致的卵贱，jdk1.8里面有一個jce的包兴泥，安全性機制導(dǎo)致的訪問https會報錯倔既，官網(wǎng)上有替代的jar包攀唯，如果替換掉就可以了.
這兩個jar包的下載地址：http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html
下載之后低飒，把這個壓縮文件解壓霹崎，得到兩個jar包去覆蓋jdk安裝目錄下的jre\lib\security\下相同的jar包就能解決java8的郵件發(fā)送問題胯陋。
