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;

}
