EWS Java Api connecting to office 365

Question

我想在代码中获取日历详细信息，但我决定先检查是否可以连接到outlook 365。

public static void main(String[] args) throws Exception {
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);//not sure if it should be SP1 or SP2
    ExchangeCredentials credentials = new WebCredentials("[e-mail]", "Redstorm#02");
    service.setCredentials(credentials);

    try {
        System.out.println("Check");
        service.setUrl(new URI("https://outlook.office365.com/EWS/Exchange.asmx"));
        service.setTraceEnabled(true);
        EmailMessage msg = new EmailMessage(service);
        msg.setSubject("Hello world!");
        msg.setBody(MessageBody.getMessageBodyFromText("Sent using the EWS Managed API."));
        msg.getToRecipients().add("[e-mail]");
        msg.send();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

我在将代码与Office 365集成时也遇到了一些问题。目前，使用从以下URL构建的ews-java-api-2.0 jar似乎对我有效：ews java api Github页面

import java.net.URI;
import java.net.URISyntaxException;
import microsoft.exchange.webservices.data.core.service.item.EmailMessage;
import microsoft.exchange.webservices.data.core.ExchangeService;
import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
import microsoft.exchange.webservices.data.credential.ExchangeCredentials;
import microsoft.exchange.webservices.data.credential.WebCredentials;
import microsoft.exchange.webservices.data.property.complex.MessageBody;
public class App 
{
    public static void main( String[] args )
    {
        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
        ExchangeCredentials credentials = new WebCredentials("USERNAME@DOMAIN", "PASSWORD");
        service.setCredentials(credentials);
        try 
        {
            service.setUrl(new URI("https://outlook.office365.com/EWS/Exchange.asmx"));
            EmailMessage msg = new EmailMessage(service);
            msg.setSubject("Hello world!");
            msg.setBody(MessageBody.getMessageBodyFromText("Sent using the EWS Java API."));
            msg.getToRecipients().add("RECIPIENTMAIL@DOMAIN");
            msg.send();
        } 
        catch (Exception e) 
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

我在这个测试中使用了Maven项目，下面是我的pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </dependency>
    <dependency>

        <artifactId>commons-lang3</artifactId>
        <version>3.4</version>
    </dependency>
  </dependencies>
</project>

希望这能有所帮助。

使用自动发现服务（对于Office365使用Exchange2010_SP2）：

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
ExchangeCredentials credentials = new WebCredentials("[e-mail]", "wont-tell-you");
service.setCredentials(credentials);
service.autodiscoverUrl("[e-mail]", 
        new IAutodiscoverRedirectionUrl() {
            @Override
            public boolean autodiscoverRedirectionUrlValidationCallback(String url) throws AutodiscoverLocalException {
                return url.toLowerCase().startsWith("https://");
            }
        });
