Java Learning to import XML into a database

      We know there are many ways to Import XML into a database by inserting the number into the database.,most of the previous contacts were throughSQLthe statement simply inserts a single piece of data,to learn today is toXMLdata is added to the database at once:

the first thing to write is an XML file :

<?xml version= "1.0" encoding= "Utf-8"?><accesos> <item> <SOCIO> <numero>00 045050</numero> <REPOSICION>0</REPOSICION> <nombre>moises Moreno</nombre&gt           ; <TURNOS> <LU>T1</LU> <MA>T2</MA> &LT;MI&GT;T3&L t;/mi> <JU>T4</JU> <VI>T5</VI> <sa>t6</sa > <DO>T7</DO> </TURNOS> </SOCIO> </item> &LT;ITEM&G         T               <SOCIO> <NUMERO>00045051</NUMERO> <REPOSICION>0</REPOSICION>                    <nombre>ruth pena</nombre> <TURNOS> <LU>S1</LU> <MA>S2</MA> <MI>S3</MI> <ju>s4</ Ju> <VI>S5</VI> <SA>S6</SA> <do>s 7</do> </TURNOS> </SOCIO> </item></ACCESOS>

          and then write the ReadXMLmethod of the file:putdom4jof theJarpackage introduced toWeb-infounder theLiband add a reference:

Import org.dom4j.document;import org.dom4j.element;import org.dom4j.io.saxreader;public static void Main (String[] args) {//Insert data SQL statement string sql= "insert into T_xml (NUMERO, reposicion, Nombre, Turnos) VALUES (?,?,?,?)"; Connection Conn=null; PreparedStatement pstmt=null;try{conn=dbutil.getconnection ();p stmt=conn.preparestatement (SQL);//Read XML file document Doc=new Saxreader (). Read (New File ("f:/j2eemyself/drp/test_xmlimport/xml/test01. XML ");//Select the node of the XML file list itemlist=doc.selectnodes (" Accesos/item/socio ");//traverse the read out of the XML node for (Iterator iter=    Itemlist.iterator (); Iter.hasnext ();) {element el= (Element) Iter.next ();    Reads the node content String numero=el.elementtext ("numero"); String reposicion = El.elementtext ("reposicion"); String nombre = El.elementtext ("nombre");//traverse the contents of the Turnos node list turnoslist = El.elements ("Turnos"); StringBuffer sbstring=new StringBuffer (); for (Iterator Iter1=turnoslist.iterator (); Iter1.hasnext ();) {Element turnoselt= (Element) iter1.next (); String lu = Turnoselt.elementtext ("Lu"); String ma = turnoselt.elementtext ("Ma"); String mi = turnoselt.elementtext ("Mi"); String Ju = Turnoselt.elementtext ("Ju"); String VI = turnoselt.elementtext ("VI"); String sa = turnoselt.elementtext ("sa");  String doo = Turnoselt.elementtext ("Do"), Sbstring.append (Lu + "," + Ma + "," + mi + "," + Ju + "," + VI + "," + sa + "," + doo);} Assign a value for SQL statement pstmt.setstring (1, numero);p stmt.setstring (2, reposicion);p stmt.setstring (3, Nombre);p stmt.setstring (4,    Sbstring.tostring ());p stmt.addbatch ();    } pstmt.executebatch (); System.out.print ("Import XML to database successfully");} catch (Exception e) {e.printstacktrace ();} Finally{dbutil.close (pstmt);D butil.close (conn);}}

It 's so simple that you can put XML The data in the file is read into the database: the results in the database:

actually put XML the data in the database is simple to read, as long as you iterate through the data in each node.
