[英]Not able to send Email using Amazon SES in Java
我正在使用下面提到的代碼發送電子郵件。
public static void send(String email, String subject, String body) {
try {
fromEmail = "abc.@xyz.com";
Content subjectContent = new Content(subject);
Destination destination = new Destination().withToAddresses(new String[] { "cde@gmail.com" });
Content htmlContent = new Content().withData("<h1>Hello - I hope you're having a good day.</h1>");
Body msgBody = new Body().withHtml(htmlContent);
// Create a message with the specified subject and body.
Message message = new Message().withSubject(subjectContent).withBody(msgBody);
SendEmailRequest request = new SendEmailRequest()
.withSource(fromEmail)
.withDestination(destination)
.withMessage(message);
SendRawEmailRequest sendRawEmailRequest = new SendRawEmailRequest()
.withSource(fromEmail)
.withDestinations(destination.getBccAddresses())
.withRawMessage(new RawMessage());
AWSCredentials credentials = new BasicAWSCredentials(userName,password);
AmazonSimpleEmailServiceClient sesClient = new AmazonSimpleEmailServiceClient(credentials);
// ListVerifiedEmailAddressesResult verifiedEmails =
// sesClient.listVerifiedEmailAddresses();
SendRawEmailResult result = sesClient.sendRawEmail(sendRawEmailRequest);
System.out.println(result + "Email sent");
} catch (Exception e) {
logger.error("Caught a MessagingException, which means that there was a "
+ "problem sending your message to Amazon's E-mail Service check the "
+ "stack trace for more information.{}" + e.getMessage());
e.printStackTrace();
}
}
我得到下面提到的錯誤。

您提供的憑據不正確。 您要提供IAM用戶名和密碼。 相反,您必須提供access_key_id
和access_key_id
。
AWSCredentials credentials = new BasicAWSCredentials(access_key_id, secret_access_key)
這是使用Amazon SES發送電子郵件的示例代碼。 最初,當您創建Amazon SES帳戶時,該帳戶將處於沙盒模式,該模式僅允許您發送200封電子郵件。 要將其切換到生產模式,您需要“請求”以擴展電子郵件限制。 請仔細閱讀文檔。
前提條件:您需要激活Amazon SES帳戶。 如果您當前處於沙盒模式,請驗證電子郵件地址(去往和來自)或域。 在導航欄中的“ SMTP設置”下,您可以生成SMTP憑據。 這將包括smtp用戶名和密碼。 您也可以下載包含此詳細信息的csv文件。
使用Java發送電子郵件:
public class AmazonSESExample {
static final String FROM = "your from email address";
static final String FROMNAME = "From name";
// Replace recipient@example.com with a "To" address. If your account
// is still in the sandbox, this address must be verified.
static final String TO = "receiver email address";
// Replace smtp_username with your Amazon SES SMTP user name.
static final String SMTP_USERNAME = "username generated under smtp settings";
// Replace smtp_password with your Amazon SES SMTP password.
static final String SMTP_PASSWORD = "password generated under smtp settings";
// Amazon SES SMTP host name. This example uses the US West (Oregon) region.
// See https://docs.aws.amazon.com/ses/latest/DeveloperGuide/regions.html#region-endpoints

static final String SUBJECT = "Amazon SES test (SMTP interface accessed using Java)";
static final String BODY = String.join(
System.getProperty("line.separator"),

System.out.println("The email was not sent.");
System.out.println("Error message: " + ex.getMessage());
