XStream implements a free transition between XML and Object

• Because the XML interaction data was used in the project, I thought of the tool (XStream) for a time, so I figured out how to use it. Through some of its own programming experience and the strong network, the ultimate easy to get done. You need to prepare the following jar packages (Xstream-1.4.7.jar, Xpp3_min-1.1.4c.jar, Xmlpull-1.1.3.1.jar)

  1. Writing the corresponding entity

• Rootbean

    @XStreamAlias("root")    publicclass RootBean {        @XStreamAlias("DocInfo")        private DocInfoBean docInfo;        @XStreamAlias("PAGES")        private List<PageBean> pages;        //getter和setter        ...    }

• Docinfobean

publicclass DocInfoBean {    @XStreamAlias("APP_CODE")    private String appCode;    @XStreamAlias("APP_NAME")    private String appName;    @XStreamAlias("BUSI_NO")    private String busiNo;    //getter和setter        ...}

• Pagebean

@XStreamAlias("Page") Public  class pagebean {    @XStreamAlias("Doc_type")@XStreamAsAttribute    PrivateString DocType;@XStreamAlias("Doc_name")@XStreamAsAttribute    PrivateString DocName;@XStreamAlias("Page_url")@XStreamAsAttribute    PrivateString Pageurl;@XStreamAlias("Page_name")@XStreamAsAttribute    PrivateString PageName;@XStreamAlias("Up_user")@XStreamAsAttribute    PrivateString Upuser;@XStreamAlias("up_org")@XStreamAsAttribute    PrivateString uporg;@XStreamAlias("Up_time")@XStreamAsAttribute    PrivateString UpTime;//getter and Setter...}

2. Xml to Object

PrivateRootbeanGetrootbean(File xmlfile) {InputStreamReader reader =NULL;Try{reader =NewInputStreamReader (NewFileInputStream (Busixmlfile),"UTF-8"); }Catch(Exception e)        {E.printstacktrace (); } XStream xstream=NewXStream (NewDomdriver ("UTF-8",NewXmlfriendlynamecoder ("-_","_"))); Xstream.alias ("Root", Rootbean.class); Xstream.autodetectannotations (true);return(Rootbean) xstream.fromxml (reader); }

2. Object to XML

public void Testobj2xmlnew () {Rootbean Rootbean = new Rootbean ();Docinfobean docinfo = new Docinfobean ();DocInfo. Setappcode("009");DocInfo. Setappname("Test");DocInfo. Setbusino("12345a");Rootbean. Setdocinfo(DocInfo);list<pagebean> pages = new arraylist<pagebean> ();for (int i=0; i<3;i++) {Pagebean page = new Pagebean ();Page. Setdocname("ID card");Page. Setdoctype("010");Page. Setpagename("0000.jpg");Page. Setpageurl("1111.jpg");Page. setuporg("HP");Page. Setuptime("34543312321");Page. Setupuser("12433124");Pages. Add(page);} Rootbean. Setpages(pages);Resolves an earlier bug ("_"When you convert to XML, it becomes"__")//xstream xstream=new XStream (New Domdriver ()); XStream xstream=new XStream (New Domdriver ("UTF-8", New Xmlfriendlynamecoder ("-_","_")));XStream. Alias("Root", Rootbean. Class);XStream. Autodetectannotations(true);String str= XStream. ToXML(Rootbean);System. out. println(str);}
