Java 来自URL的Apache多端口邮件需要cookie
我需要通过HTTP获取excel电子表格,然后将其作为附件发送到JavaSpring服务器上的电子邮件中 我发现的问题是MultiPartEmail.attach()只接受一个java.net.URL实例,我无法确定如何确保请求头中有特定的Cookie进行身份验证Java 来自URL的Apache多端口邮件需要cookie,java,spring,cookies,excel,Java,Spring,Cookies,Excel,我需要通过HTTP获取excel电子表格,然后将其作为附件发送到JavaSpring服务器上的电子邮件中 我发现的问题是MultiPartEmail.attach()只接受一个java.net.URL实例,我无法确定如何确保请求头中有特定的Cookie进行身份验证 url = new URL(urlString); email.attach(url, "test.xls", "File"); email.send(); 我曾尝试手动请求并创建工作簿,但后来我在将工作簿本身附加到Multipar

我曾尝试手动请求并创建工作簿,但后来我在将工作簿本身附加到MultipartMail上时遇到了难题
HttpClient client = new HttpClient();
GetMethod method = new GetMethod(queryString);
method.setRequestHeader("Cookie", cookie);
client.executeMethod(method);
InputStream stream = method.getResponseBodyAsStream();
Workbook workbook = Workbook.getWorkbook(stream);
email.attach(workbook, "report.xls", "forecasting report");
我需要一些方法来克服这些限制
提前感谢您的时间。由于您使用的是Spring,您可以使用其内置的电子邮件支持发送电子邮件。因此,如何从磁盘或其他地方检索文件并不重要。您可以使用MIMessageHelper发送带有附件的电子邮件,并在邮件主机上指定帐户的用户名和密码,以便进行如下身份验证:
public class EmailNotifier {
private JavaMailSenderImpl mailSender;
public void setMailSender(JavaMailSenderImpl mailSender) {
this.mailSender = mailSender;
}
public void sendMail(InternetAddress fromAddress, InternetAddress toAddress, String subject, String msg) {
MimeMessage message = mailSender.createMimeMessage();
try {
// use the true flag to indicate you need a multipart message
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(fromAddress);
helper.setTo(toAddress);
helper.setSubject(subject);
helper.setText(msg);
// let's attach the infamous windows Sample file (this time copied to c:/)
FileSystemResource file = new FileSystemResource(new File("c:/test.xls"));
helper.addAttachment("test.xls", file);
mailSender.send(message);
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
并在bean配置文件中配置JavaMailSenderImpl bean。这是通过Gmail发送电子邮件
beans.xml

谢谢,这真的很有帮助,但遥控xls仍有问题。我想我现在的问题是如何从inputstream创建本地.xls,或者从创建xls文件的url创建更低级的.xls。您使用什么容器部署应用程序?已修复!最后,我只是将原始字节放入一个临时文件,通过电子邮件发送,然后删除。谢谢,这真的很有帮助,但我仍然有远程xls的问题。我想我现在的问题是如何从inputstream创建本地.xls,或者从创建xls文件的url创建更低级的.xls。您使用什么容器部署应用程序?已修复!我最终只是将原始字节放入一个临时文件,通过电子邮件发送,然后删除它。
