User：

package com.zzj.jsonlib.vo;

import java.util.List;

import com.zzj.jsonlib.vo.user.Order;

public class User {
	private String Username;
	private String Password;
	
	private List OrderList;
	
	public User() {
	}

	public User(String username, String password) {
		Username = username;
		Password = password;
	}

	public String getUsername() {
		return Username;
	}

	public void setUsername(String username) {
		Username = username;
	}

	public String getPassword() {
		return Password;
	}

	public void setPassword(String password) {
		Password = password;
	}

	public List getOrderList() {
		return OrderList;
	}

	public void setOrderList(List orderList) {
		OrderList = orderList;
	}

	@Override
	public String toString() {
		return "User [Username=" + Username + ", Password=" + Password
				+ ", OrderList=" + OrderList + "]";
	}


}

Order：

package com.zzj.jsonlib.vo.user;

public class Order {
	private String OID;
	private String OrderStatus;
	private Address Address;

	public String getOID() {
		return OID;
	}

	public void setOID(String oID) {
		OID = oID;
	}

	public String getOrderStatus() {
		return OrderStatus;
	}

	public void setOrderStatus(String orderStatus) {
		OrderStatus = orderStatus;
	}

	public Address getAddress() {
		return Address;
	}

	public void setAddress(Address address) {
		Address = address;
	}

	@Override
	public String toString() {
		return "Order [OID=" + OID + ", OrderStatus=" + OrderStatus
				+ ", Address=" + Address + "]";
	}

}

Address：

package com.zzj.jsonlib.vo.user;

public class Address {
	private String State;

	public String getState() {
		return State;
	}

	public void setState(String state) {
		State = state;
	}

	@Override
	public String toString() {
		return "Adrress [State=" + State + "]";
	}
	
	
	
}
