xstream转换xml和Java对象

源代码可看：https://pan.baidu.com/s/1jniElgsZ4g39ISz1Vl5U-g ，里面有xstream.jar包

结构显示样式：

ItemInterface类：

public class ItemInterface {

    private String Sender = "";
    private String Receiver = "";
    private String Billtype = "";
    private Vector Items = new Vector<>();
    
    public ItemInterface( Vector Items ){
        this.Items = Items;
    }

   get.....

   set....

}

Item类：

public class Item {

    private String CHILD_ID = "";
    private String REV_ID = "";
    private String CHILD_NAME = "";
    private String MATERIAL = "";
    private ItemForm ITEM_FORM = null;
    
    public Item (String CHILD_ID,String REV_ID,String CHILD_NAME,String MATERIAL,ItemForm ITEM_FORM){
        this.CHILD_ID = CHILD_ID;
        this.REV_ID = REV_ID;
        this.CHILD_NAME = CHILD_NAME;
        this.MATERIAL = MATERIAL;
        this.ITEM_FORM = ITEM_FORM;
    }

   get.....

   set....

}

ItemForm类：

public class ItemForm {

    private String OWNER_USER = "";
    private String OWNER_GROUP = "";
    private String UNIT = "";
    
    public ItemForm(String OWNER_USER,String OWNER_GROUP,String UNIT){
        this.OWNER_USER = OWNER_USER;
        this.OWNER_GROUP = OWNER_GROUP;
        this.UNIT = UNIT;
    }

   get.....

   set....

}

xstream序列转换：

public class Serialize {

    private static String xmlHead = "\n";
    
    /**
     * 
Description: 将ItemInterface对象序列化为XML信息并生成XML文件
     * */
    public static void serializeItemsToXMLFile(ItemInterface iteminterface , String xmlpath) throws Exception{
        //1.XmlFriendlyNameCoder当类中名称有单下划线的时候，转成XML时候会变成双下划线，如BOM对象中的CHILD_ID，则转换成XML标签时候则为CHILD__ID
        //解决单下划线变双下划线的方法就是使用XmlFriendlyNameCoder，如XmlFriendlyNameCoder("-_", "_")
        XStream iteminterfaceXS = new XStream(new DomDriver("UTF-8",new XmlFriendlyNameCoder("-_","_")));
        //2.对自定义的类名或者变量名创建别名以对应生成的XML元素名称更加简洁（可选）
        //如Item.class不定义，则标签为<包名.Item>,如果定义别名为ITEM，则标签显示为
        iteminterfaceXS.alias("Interface", ItemInterface.class);
        iteminterfaceXS.alias("ITEM", Item.class);
        //3.自定义标签，如将ItemInterface中Vector Items的Item中ITEMFORM的 ITEM_FORM的标签改为

        //iteminterfaceXS.aliasField("FORM", Item.class, "ITEM_FORM");
        
      //4.useAttributeFor为标签定义属性，如为TTEMS对应标签Interface标签定义属性Sender，则标签显示为
        iteminterfaceXS.useAttributeFor(ItemInterface.class, "Sender");
        iteminterfaceXS.useAttributeFor(ItemInterface.class, "Receiver");
        iteminterfaceXS.useAttributeFor(ItemInterface.class, "Billtype");
        //5.addImplicitCollection该方法的作用是引入隐含集合（Implicit Collection），即某个类包含集合（Vector等）字段，
        //引入隐含集合方法可以在生成的XML中并不显示集合字段的标签。
        //如想将类中Items Vecotr对应的标签隐藏掉（隐掉的效果是否则将显示）
