Excel转换成Xml

JAR包：
JDK1.6和jxl.jar

需求：
EXCEL文件类似如下：
见：附件

XML文件类似如下：
见：附件

Model类（以防参数太多而建立的类）

package com.island;

public class User {

    /**
     * UID
     */
    private static final long serialVersionUID = 346821702783141852L;
    
    private String username;
    private String usermail;
    private String password;
    
    
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getUsermail() {
		return usermail;
	}
	public void setUsermail(String usermail) {
		this.usermail = usermail;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
    
    

}

Title借口（关键词借口）

package com.island;
public interface UserKeys {
    
	public static final String USER_NAME_VALUE = "用户名";
	public static final String USER_EMAIL_VALUE = "用户邮箱";
	public static final String USER_PASSWORD_VALUE = "用户密码";

最后实现附件中的样式，简单的用这个方法可能有点复杂，建议这样做，对以后改进有很好的帮助！
