java simpleXml序列化反序列化小例子

Customer.java

Address.java

Order.java

package com.fei;import java.util.ArrayList;import java.util.Date;import java.util.List;import org.simpleframework.xml.Element;import org.simpleframework.xml.ElementList;import org.simpleframework.xml.Root;@Rootpublic class Order {@Elementprivate String code;@Elementprivate Date date;@ElementList(required = false,type = Item.class)private List<Item> items = new ArrayList<Item>();public Order(){super();}public Order(String code, Date date, List<Item> items) {super();this.code = code;this.date = date;this.items = items;}public String getCode() {return code;}public void setCode(String code) {this.code = code;}public Date getDate() {return date;}public void setDate(Date date) {this.date = date;}public List<Item> getItems() {return items;}public void setItems(List<Item> items) {this.items = items;}}

Item.java

package com.fei;import org.simpleframework.xml.Element;import org.simpleframework.xml.Root;@Rootpublic class Item {@Elementprivate String code;@Elementprivate String name;@Elementprivate int quatity;public Item(){super();}public Item(String code, String name, int quatity) {super();this.code = code;this.name = name;this.quatity = quatity;}public String getCode() {return code;}public void setCode(String code) {this.code = code;}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getQuatity() {return quatity;}public void setQuatity(int quatity) {this.quatity = quatity;}}

CustomerTest.java

package test;import java.io.File;import java.util.ArrayList;import java.util.Date;import java.util.List;import org.simpleframework.xml.Serializer;import org.simpleframework.xml.core.Persister;import com.fei.Address;import com.fei.Customer;import com.fei.Item;import com.fei.Order;public class CustomerTest {public static void main(String[] args) throws Exception{Customer customer = create();String filePath = "d:/customerOrder.xml";//序列化，把对象转为xmlwrite(customer,filePath);//反序列化，xml转为对象read(filePath);}private static  Customer create(){List<Item> items = new ArrayList<Item>();Item item1 = new Item("apple","苹果",5);Item item2 = new Item("banana","香蕉",3);Item item3 = new Item("grape","葡萄",6);items.add(item1);items.add(item2);items.add(item3);List<Order> orders = new ArrayList<Order>();Order order1 = new Order("order001",new Date(),items);orders.add(order1);Address address = new Address("888888","深圳科技园xx");Customer customer = new Customer("1001","张三",address,orders);return customer;}private static void write(Customer customer,String filePath) throws Exception{File file = new File(filePath);Serializer serializer = new Persister();serializer.write(customer,file);}private static void read(String filePath) throws Exception{File file = new File(filePath);Serializer serializer = new Persister();Customer customer = serializer.read(Customer.class, file);print(customer);}private static void print(Customer customer){System.out.println("--"+customer.getCode());System.out.println("--"+customer.getName());System.out.println("--"+customer.getAddress().getName());for(Order order : customer.getOrders()){System.out.println("----"+order.getCode());System.out.println("----"+order.getDate());for(Item item : order.getItems()){System.out.println("------"+item.getCode());System.out.println("------"+item.getName());System.out.println("------"+item.getQuatity());}}}}

运行结果：

--1001
--张三
--深圳科技园xx
----order001
----Wed Jun 18 09:37:30 CST 2014
------apple
------苹果
------5
------banana
------香蕉
------3
------grape
------葡萄
------6
