java ews_Java---使用EWS 写个ExchangeMailUtil

依赖包：

commons-httpclient-3.1.jar

commons-codec-1.10.jar

commons-logging-1.2.jar

jcifs-1.3.17.jar

代码示例：

创建MailBean类：

import java.util.Date;

public class MailBean {

public BigDecimal getId() {

return id;

}

public void setId(BigDecimal id) {

this.id = id;

}

public String getTitle() {

return title;

}

public void setTitle(String title) {

this.title = title;

}

public String getFromPeople() {

return fromPeople;

}

public void setFromPeople(String fromPeople) {

this.fromPeople = fromPeople;

}

public String getReceivePeople() {

return receivePeople;

}

public void setReceivePeople(String receivePeople) {

this.receivePeople = receivePeople;

}

public Date getReceiveTime() {

return receiveTime;

}

public void setReceiveTime(Date receiveTime) {

this.receiveTime = receiveTime;

}

public String getReadUrl() {

return readUrl;

}

public void setReadUrl(String readUrl) {

this.readUrl = readUrl;

}

public int getIsRead() {

return isRead;

}

public void setIsRead(int isRead) {

this.isRead = isRead;

}

public String getMailId() {

return mailId;

}

public void setMailId(String mailId) {

this.mailId = mailId;

}

public MailBean() {

}

public MailBean(BigDecimal id,String title, String fromPeople, String receivePeople, Date receiveTime, String mailId,

String readUrl, int isRead) {

this.id=id;

this.title = title;

this.fromPeople = fromPeople;

this.receivePeople = receivePeople;

this.receiveTime = receiveTime;

this.mailId = mailId;

this.readUrl = readUrl;

this.isRead = isRead;

}

private BigDecimal id;

private String title;

private String mailId;

private String fromPeople;

private String receivePeople;

private Date receiveTime;

private String readUrl;

private int isRead;

}
