ExchangeService初始化
ExchangeService是Ews(ExchangeWebService)接口调用基础,如果想要调用Ews所有相关接口必须以ExcahngeService为基础
ExchangeService初始化分为三个步骤：
1.创建ExchangeService对象，需传入当前Exchange服务版本。目前Ews可选ExchangeService版本有以下几个版本
1) Exchange2007_SP1
2) Exchange2010
3) Exchange2010_SP1
4) Exchange2010_SP2
创建ExchangeService对象代码示例：
ExchangeService exchangeService = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
2.创建ExchangeCredentials对象。ExchangeCredentials是ExchangeService信任凭据对象，所以在初始化的时候需要传入身份相关信息。
创建ExchangeCredentials对象示例代码:
ExchangeCredentials exchangeCredentials = new WebCredentials(username, password);
3.为ExchangeService设置信任凭据，ExchangeService服务Url
示例代码：
exchangeService.setCredentials(exchangeCredentials);
exchangeService.setUrl(new URI("ExhcangeWebService服务Url"));
exchangeService.setTraceEnabled(true);
在这里特别说明一下，如果您不想设置Url，您可以采用ExchangeService自动发现，这也是Ews推荐方式
示例代码如下:
exchangeService.autodiscoverUrl("ExchangeWebService所在域");
初始化代码合并起来如下：
ExchangeService exchangeService = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
ExchangeCredentials exchangeCredentials = new WebCredentials(username, password);
exchangeService.setCredentials(exchangeCredentials);
exchangeService.setUrl(new URI(ewsConfigProperties.getServerUrl()));
exchangeService.setTraceEnabled(true);
