我想我已经用尽了这个选项。我已经在互联网上搜索了好几天,找不到有类似问题的人。

我使用EWS Java API 1.2.1连接到Exchange服务器并打开我的收件箱文件夹以查找电子邮件。这是我的代码:

import java.net.URI;

import microsoft.exchange.webservices.data.*;

public class Connection {

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception {

        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);

        ExchangeCredentials credentials = new WebCredentials("myUser", "myPass");

        service.setCredentials(credentials);

        service.setUrl(new URI("https://example.com/ews/exchange.asmx"));

        service.setTraceEnabled(true);

        Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox);
        System.out.println("messages: " + inbox.getTotalCount());
    }
}

当我运行它时,我收到以下错误:

Exception in thread "main" microsoft.exchange.webservices.data.ServiceLocalException: https://example.com/ews/exchange.asmx : Connection error 
at microsoft.exchange.webservices.data.ExchangeServiceBase.prepareHttpWebRequestForUrl(Unknown Source)

at microsoft.exchange.webservices.data.Folder.bind(Unknown Source)
at microsoft.exchange.webservices.data.Folder.bind(Unknown Source)
at Connection.main(Connection.java:22)

我认为这可能会阻止我的连接尝试,但是当我使用JWebServices API时,它确实可以使用上述URL和用户凭据。

顺便说一句,我也可以从我的浏览器访问WSDL。

任何线索?

这可能是因为引用了此类的错误JAR。

您使用的JAR是什么?这里使用的是哪个版本的EWS API。??

我在使用EWS API 1.2时遇到了同样的问题,在引用以下JAR之后,它得到了解决。

EWSJavaAPI_1.2original.jar, EWSJavaAPIWithJars_1.2.1.jar, HttpClient的-4.2.5.jar, 的HttpCore-4.2.4.jar, JCIFS-1.3.17.jar, 公地编解码器1.7.jar, 共享记录-1.1.1.jar

EWSJavaAPI_1.2original.jar - 这是与微软相关的类 EWSJavaAPIWithJars_1.2.1.jar - 这个有连接相关的类。

尝试添加这些JAR。

的问候,
