今天學(xué)習(xí)了一下JavaMail，javamail發(fā)送郵件確實(shí)是一個(gè)比較麻煩的問(wèn)題。為了以后使用方便，自己寫(xiě)了段代碼，打成jar包，以方便以后使用。呵呵?

以下三段代碼是我的全部代碼，朋友們?nèi)绻胗?#xff0c;直接復(fù)制即可。

第一個(gè)類(lèi)：MailSenderInfo.java?

第三個(gè)類(lèi)：MyAuthenticator.java?

?

package?com.util.mail;???
??
import?javax.mail.*;???
?????
public?class?MyAuthenticator?extends?Authenticator{???
????String?userName=null;???
????String?password=null;???
????????
????public?MyAuthenticator(){???
????}???
????public?MyAuthenticator(String?username,?String?password)?{????
????????this.userName?=?username;????
????????this.password?=?password;????
????}????
????protected?PasswordAuthentication?getPasswordAuthentication(){???
????????return?new?PasswordAuthentication(userName,?password);???
????}???
}???

下面給出使用上面三個(gè)類(lèi)的代碼：

public?static?void?main(String[]?args){???
?????????//這個(gè)類(lèi)主要是設(shè)置郵件???
??????MailSenderInfo?mailInfo?=?new?MailSenderInfo();????
??????mailInfo.setMailServerHost("smtp.163.com");????
??????mailInfo.setMailServerPort("25");????
??????mailInfo.setValidate(true);????
??????mailInfo.setUserName("han2000lei@163.com");????
??????mailInfo.setPassword("**********");//您的郵箱密碼????
??????mailInfo.setFromAddress("han2000lei@163.com");????
??????mailInfo.setToAddress("han2000lei@163.com");????
??????mailInfo.setSubject("設(shè)置郵箱標(biāo)題?如http://www.guihua.org?中國(guó)桂花網(wǎng)");????
??????mailInfo.setContent("設(shè)置郵箱內(nèi)容?如http://www.guihua.org?中國(guó)桂花網(wǎng)?是中國(guó)最大桂花網(wǎng)站==");????
?????????//這個(gè)類(lèi)主要來(lái)發(fā)送郵件???
??????SimpleMailSender?sms?=?new?SimpleMailSender();???
??????????sms.sendTextMail(mailInfo);//發(fā)送文體格式????
??????????sms.sendHtmlMail(mailInfo);//發(fā)送html格式???
????}??

最后，給出朋友們幾個(gè)注意的地方：?
1、使用此代碼你可以完成你的javamail的郵件發(fā)送功能。三個(gè)類(lèi)缺一不可。?
2、這三個(gè)類(lèi)我打包是用的com.util.mail包，如果不喜歡，你可以自己改，但三個(gè)類(lèi)文件必須在同一個(gè)包中?
3、不要使用你剛剛注冊(cè)過(guò)的郵箱在程序中發(fā)郵件，如果你的163郵箱是剛注冊(cè)不久，那你就不要使用“smtp.163.com”。因?yàn)槟惆l(fā)不出去。剛注冊(cè)的郵箱是不會(huì)給你這種權(quán)限的，也就是你不能通過(guò)驗(yàn)證。要使用你經(jīng)常用的郵箱，而且時(shí)間比較長(zhǎng)的。?
4、另一個(gè)問(wèn)題就是mailInfo.setMailServerHost("smtp.163.com");與mailInfo.setFromAddress("han2000lei@163.com");這兩句話。即如果你使用163smtp服務(wù)器，那么發(fā)送郵件地址就必須用163的郵箱，如果不的話，是不會(huì)發(fā)送成功的。?
5、關(guān)于javamail驗(yàn)證錯(cuò)誤的問(wèn)題，網(wǎng)上的解釋有很多，但我看見(jiàn)的只有一個(gè)。就是我的第三個(gè)類(lèi)。你只要復(fù)制全了代碼，我想是不會(huì)有問(wèn)題的。
