java讀取exchange服務器，以及遇到的坑

1.我遇到的坑

一、坑：

有沒有人和我一樣一直是401問題，EWS problem (error 401) 這個是一個大坑，是在安裝exchange的時候沒有裝配，我下面給大家說一下如何搞

（1）查看IIS的版本

2.安裝配置exchange

  對策：進入C:/WINDOWS/Microsoft.NET/Framework/相應版本/（或者 C:\Windows\Microsoft.NET\Framework\v4.0.30319）打開cmd ,運行aspnet_regiis -i,解決

二、坑：

證書問題，我有來凝重解決方案

（1）繞過證書認證

import microsoft.exchange.webservices.data.EWSConstants;
import microsoft.exchange.webservices.data.core.EwsSSLProtocolSocketFactory;
import microsoft.exchange.webservices.data.core.ExchangeService;
import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
import org.apache.http.config.Registry;
import org.apache.http.config.RegistryBuilder;
import org.apache.http.conn.socket.ConnectionSocketFactory;
import org.apache.http.conn.socket.PlainConnectionSocketFactory;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLSession;
import java.security.GeneralSecurityException;

public class ExchangeServiceWithHostVerify extends ExchangeService {


    //不對任何域名做驗證
    private final static HostnameVerifier hostnameVerifierWithOutVerfy = new HostnameVerifier(){
        @Override
        public boolean verify(String s, SSLSession sslSession) {
            return true;
        }
    };

    public ExchangeServiceWithHostVerify() {
        super();
    }
    public ExchangeServiceWithHostVerify(ExchangeVersion requestedServerVersion) {
        super(requestedServerVersion);
    }

    protected Registry<ConnectionSocketFactory> createConnectionSocketFactoryRegistry() {
        try {
            return RegistryBuilder.<ConnectionSocketFactory>create().register(EWSConstants.HTTP_SCHEME, new PlainConnectionSocketFactory()).register(EWSConstants.HTTPS_SCHEME, EwsSSLProtocolSocketFactory.build(null,hostnameVerifierWithOutVerfy)).build();
        } catch (GeneralSecurityException e) {
            throw new RuntimeException(
                    "Could not initialize ConnectionSocketFactory instances for HttpClientConnectionManager", e
            );
        }
    }



}

ExchangeService service = new ExchangeServiceWithHostVerify(ExchangeVersion.Exchange2010_SP2);

（2）其實不用ip的這個東西本來就有問題，直接在服務器上查找域名就可以了

域名就是計算機名字

三、坑：

防火牆關閉

 

2.代碼

import microsoft.exchange.webservices.data.core.ExchangeService;
import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
import microsoft.exchange.webservices.data.core.enumeration.property.WellKnownFolderName;
import microsoft.exchange.webservices.data.core.service.folder.Folder;
import microsoft.exchange.webservices.data.core.service.item.EmailMessage;
import microsoft.exchange.webservices.data.core.service.item.Item;
import microsoft.exchange.webservices.data.credential.ExchangeCredentials;
import microsoft.exchange.webservices.data.credential.WebCredentials;
import microsoft.exchange.webservices.data.search.FindItemsResults;
import microsoft.exchange.webservices.data.search.ItemView;
import java.net.URI;
import java.util.ArrayList;
