Javamail發送帶附件的郵件適用於Windows，但不適用於Linux

在Tomcat 6.0上使用Javamail發送帶附件的電子郵件時遇到問題。Javamail發送帶附件的郵件適用於Windows，但不適用於Linux

在我的機器上使用Tomcat服務器發送郵件時（Windows 7 64），它工作正常。我已經用本地smtp服務器和一個Gmail賬戶作爲中繼來測試它。但是，當我的遠程Tomcat服務器（運行linux）發送郵件時，收到的郵件亂七八糟，沒有主題，附件顯示爲文本（原始爲pdf文件），並且一些郵件標頭與郵件混合在一起。我嘗試過使用在Windows上測試時使用的相同方法：嘗試使用本地smtp服務器，然後使用gmail作爲中繼。它在兩種情況下都不起作用。

我也嘗試更改我的本地JavaMail庫，並使用遠程服務器上的相同內容（從服務器複製到我的機器），但運行本地的結果始終相同。電子郵件以預期的方式收到。

當我發送電子郵件時，它會發送另一份副本給我，所以我可以跟蹤發生了什麼。在日誌下面展示了兩種郵件（原件和複印件），運行使用嵌入在我的j2ee.jar JavaMail的本地測試時（請參見下面的其他細節）JAVAMAIL輸出：

在我的遠程服務器上，我們有上下文/ WEB-INF/lib中的JavaMail庫。我們擁有一個mail.jar和一個包含JavaMail的j2ee.jar。另外，在tomcat文件夾中還有另一個mail.jar（可以在日誌中看到）和另一個包含Javamail的j2ee.jar。

我試着用最近的一個替換服務器的/WEB-INF/lib/mail.jar，但日誌甚至沒有改變。在我的本地測試中使用來自服務器的.jars會產生正確的結果。

請注意，我的服務器不顯示一些應該存在的調試行。

下面是用來發送電子郵件的代碼：

Properties props = new Properties(); 
props.put("mail.smtp.debug", "true"); 
props.put("mail.smtp.auth", "true"); 
props.put("mail.mime.charset", "ISO-8859-1"); 
props.put("mail.smtp.starttls.enable", "true"); 
props.put("mail.smtp.starttls.required", "true"); 
props.put("mail.smtp.host", smtpHost); 
props.put("mail.smtp.port", Integer.toString(port)); 
this.session = Session.getInstance(props, 
    new javax.mail.Authenticator() { 
     protected PasswordAuthentication getPasswordAuthentication() { 
     return new PasswordAuthentication(usr, pass); 
     } 
}); 

MimeMultipart mp = new MimeMultipart("mixed"); 
MimeBodyPart txtPart = new MimeBodyPart(); 

if(this.message == null){ 
    if(this.session != null){ 
     this.message = new MimeMessage(this.session); 
    } else { 
     throw new Exception(""); 
    } 
} 

this.session.setDebug(true); 
this.message.setFrom(new InternetAddress(this.from)); 
this.message.setRecipient(Message.RecipientType.TO, new InternetAddress(this.to)); 
this.message.setSubject(this.subject); 

txtPart.setDisposition(Part.INLINE); 
txtPart.setText(text); 
mp.addBodyPart(txtPart); 

for (int i = 0; i < this.attach.size(); i++) { 
    MimeBodyPart filePart = new MimeBodyPart(); 
    File file = (File) this.attach.elementAt(i); 
    FileDataSource fds = new FileDataSource(file); 
    DataHandler dh = new DataHandler(fds); 
    filePart.setFileName(file.getName()); 
    filePart.setDisposition(Part.ATTACHMENT); 
    filePart.setDescription("Attached file: " + file.getName()); 
    filePart.setDataHandler(dh); 
    mp.addBodyPart(filePart); 
} 

this.message.setContent(mp); 

Transport.send(this.message);

任何進一步的細節需要，請詢問。

感謝您的考慮！

嘗試從應用程序中刪除j2ee.jar;其中包含某些JavaMail類的舊版本，這可能與mail.jar中的較新版本衝突。

（j2ee.jar的僅作爲一些在編譯時使用;它不應該在運行時使用）

它並沒有奏效。我將JavaMail 1.4.5複製到/ WEB-INF/lib /並刪除了j2ee.jar。 JavaMail調試輸出保持不變，就好像我沒有刪除j2ee.jar並將新的JavaMail複製到應用程序庫。我誤解了Tomcat安裝中的j2ee.jar，但我可以確認那裏有一個mail.jar，裏面有JavaMail 1.3.1類。我需要確保刪除該文件能夠解決問題，因爲我們公司在該服務器上有其他產品，並且我不知道是否刪除該mail.jar（在tomcat安裝內）會中斷任何應用程序。謝謝！ – b020 2012-04-27 20:00:56

還有一個Tomcat選項可以讓你的應用中的類優先於服務器中的類;這可能有助於這裏。 – 2012-04-27 23:17:23

我找不到任何關於此的內容。也許我在搜索中使用了錯誤的關鍵字。你能指點一下如何改變這個選項的方向嗎？ – b020 2012-04-30 18:03:38

Javamail發送帶附件的郵件適用於Windows，但不適用於Linux
