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;
}
