java.lang.NoClassDefFoundError:org/apache/http/conn/scheme/SchemeSocketFactory

Question

我想通过AWSCredentials发送邮件但是获得例外

java.lang.NoClassDefFoundError:org/apache/http/conn/scheme/SchemeSocketFactory

我添加了这些jar:

• AWS-Java的SDK-1.3.11.jar
• AWS-Java的SDK-1.3.11-javadoc.jar
• AWS-Java的SDK-1.3.11-sources.jar
• AWS-Java的SDK流 - 构建 - 工具 - 1.3.11.jar
• 公共-logging.jar
• HttpClient的-4.0-alpha4.jar
• 的HttpCore-4.0-alpha6.jar
• log4j的-1.2.13.jar
• 的mail.jar

我的java代码是 -

 import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.simpleemail.AmazonSimpleEmailServiceClient;
import com.amazonaws.services.simpleemail.model.*;
import java.util.LinkedList;

public class SESExample {
public static final String ACCESS_KEY = "My Access";
public static final String SECRET_KEY = "My Secret";

public static void main(String args[]) {
    String sender = "support@brandzter.com"; // should be verified email

    LinkedList<String> recipients = new LinkedList<String>();
    recipients.add("khoyendra@globussoft.com"); // again a verified email, if you are in sandbox

    SendMail(sender, recipients, "Hi", "Hi how are u?");
}

public static void SendMail(String sender, LinkedList<String> recipients, String subject, String body) {
    Destination destination = new Destination(recipients);

    Content subjectContent = new Content(subject);
    Content bodyContent = new Content(body);
    Body msgBody = new Body(bodyContent);
    Message msg = new Message(subjectContent, msgBody);

    SendEmailRequest request = new SendEmailRequest(sender, destination, msg);

    AWSCredentials credentials = new BasicAWSCredentials(ACCESS_KEY, SECRET_KEY);
    AmazonSimpleEmailServiceClient sesClient = new AmazonSimpleEmailServiceClient(credentials);
    SendEmailResult result = sesClient.sendEmail(request);

    System.out.println(result);
}

}

我也试图搜索这个罐子,但没有得到.我使用错误的罐子不确定.任何人都可以告诉我这是什么问题？

从javadocs开始,SchemeSocketFactory该类仅在4.1版本之后可用.所以这可能与您使用4.0 alpha jar这一事实有关.尝试将您的http-client库升级到4.1或更高版本.
