連接到Office365 Exchange服務器與EWS-Java的API-2.0.jar在Java核心

Question

我使用EWS-Java的API-2.0.jar，連接到office365以下是示例代碼：

package javaapplication6; 

import java.net.URI; 
import microsoft.exchange.webservices.data.autodiscover.IAutodiscoverRedirectionUrl; 

import microsoft.exchange.webservices.data.credential.ExchangeCredentials; 
import microsoft.exchange.webservices.data.core.ExchangeService; 
import microsoft.exchange.webservices.data.core.enumeration.property.WellKnownFolderName; 
import microsoft.exchange.webservices.data.core.service.folder.Folder; 
import microsoft.exchange.webservices.data.credential.WebCredentials; 

public class JavaApplication6 { 

    public static class RedirectionUrlCallback implements IAutodiscoverRedirectionUrl { 
     public boolean autodiscoverRedirectionUrlValidationCallback(String redirectionUrl) { 
      return redirectionUrl.toLowerCase().startsWith("https://"); 
     } 
    } 

    public static ExchangeService connectViaExchangeManually(String email, String password) 
     throws Exception { 
     ExchangeService service = new ExchangeService(); 
     ExchangeCredentials credentials = new WebCredentials(email, password); 
     service.setUrl(new URI("https://outlook.office365.com/EWS/Exchange.asmx")); 
     service.setCredentials(credentials); 
     service.setTraceEnabled(true); 
     Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox); 
     System.out.println("messages: " + inbox.getTotalCount()); 
     return service; 
    } 

    public static ExchangeService connectViaExchangeAutodiscover(String email, String password) { 
     ExchangeService service = new ExchangeService(); 
     try { 
      service.setCredentials(new WebCredentials(email, password)); 
      service.autodiscoverUrl(email, new RedirectionUrlCallback()); 
      service.setTraceEnabled(true); 
      Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox); 
      System.out.println("messages: " + inbox.getTotalCount()); 
     } 
     catch (Exception e){ 
      e.printStackTrace(); 
     } 
     return service; 
    } 
    public static void main(String[] args) { 
     try { 
     ExchangeService service = connectViaExchangeManually("<name>@<company>.onmicrosoft.com", "<password>"); 
     } catch (Exception e) { 
     e.printStackTrace(); 
     } 
    } 

} 

當我運行從NetBeans IDE中的代碼，獲得以下錯誤：

run: 
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/config/Lookup 
    at javaapplication6.JavaApplication6.connectViaExchangeAutodiscover(JavaApplication6.java:33)

我在這裏停留，因爲2天后，任何幫助，將不勝感激！

Answer 1

喜添加以下jar文件

EWSJavaAPI_1.2original.jar 
EWSJavaAPIWithJars_1.2.1.jar 
httpclient-4.2.5.jar 
httpcore-4.2.4.jar 
jcifs-1.3.17.jar 
commons-codec-1.7.jar 
commons-logging-1.1.1.jar 

來解決。你需要在Chrome瀏覽器中打開URL所有的依賴 -

https://outlook.office365.com/EWS/Exchange.asmx

然後輸入您的身份驗證憑據的用戶名和密碼，你將在你的下面的代碼中使用。

package EWSJavaAPI; 

import java.net.URI; 

import microsoft.exchange.webservices.data.ExchangeCredentials; 
import microsoft.exchange.webservices.data.ExchangeService; 
import microsoft.exchange.webservices.data.ExchangeVersion; 
import microsoft.exchange.webservices.data.Folder; 
import microsoft.exchange.webservices.data.IAutodiscoverRedirectionUrl; 
import microsoft.exchange.webservices.data.WebCredentials; 
import microsoft.exchange.webservices.data.WellKnownFolderName; 

public class EWSJavaAPI { 

    public static class RedirectionUrlCallback implements IAutodiscoverRedirectionUrl { 
     public boolean autodiscoverRedirectionUrlValidationCallback(String redirectionUrl) { 
      return redirectionUrl.toLowerCase().startsWith("https://"); 
     } 
    } 

    public static ExchangeService connectViaExchangeAutodiscover(String email, String password) { 
     ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2); 
     try { 

      service.setCredentials(new WebCredentials(email, password)); 
      service.autodiscoverUrl(email, new RedirectionUrlCallback()); 
      service.setTraceEnabled(true); 
      Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox); 
      System.out.println("messages: " + inbox.getTotalCount()); 
     } 
     catch (Exception e){ 
      e.printStackTrace(); 
     } 
     return service; 
    } 
    public static void main(String[] args) { 
     try { 
      System.out.println("Hello World"); 
      ExchangeService service = connectViaExchangeAutodiscover("user@domain.com", "xxxxxx"); 

     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
} 

它在Office365的結尾工作得很好。
