用intellijidea編寫java的發(fā)送郵件,接收郵件,發(fā)送帶附件的郵件

1、廣西民族大學(xué)實 驗 報 告學(xué)院： 班級 11信計 姓名 學(xué)號 分數(shù) 實驗日期 2014.5.11 指導(dǎo)老師 秦董洪 實驗名稱 用java實現(xiàn)郵件的發(fā)送和接收 實驗內(nèi)容:編寫一個發(fā)送和接收郵件信息的郵件程序，包括郵件中附件的發(fā)送與接收。實驗所用軟件:Intellij idea 13.0實驗過程:(1).在D盤下新建兩個文本文件,分別是sendEmail.txt和receiveEmail.txt,在這兩個文件里加上兩行數(shù)據(jù),第一行是郵箱地址,第二行是密碼.前者是記錄著發(fā)送郵件的郵箱地址與郵箱密碼,后者記錄著查看接收郵件的郵箱地址與密碼(2).打開Intellij idea，按FileNew mod

2、ule，新建一個java模塊,命名為Email.如下圖所示:(3).在Intellij idea的project面板窗口里，雙擊展開Email，右鍵單擊它的子文件夾“src”，新建一個”java”文件，命名為“Email.java”(4).編寫出程序的實現(xiàn)代碼/EmailHandler.javaimport javax.activation.DataHandler;import javax.activation.FileDataSource;import javax.mail.*;import ernet.InternetAddress;import javax.m
