把xml转为成javaBean javaBean转为成xml

1.先定义javaBean
package com.wutka.jox.test;

import com.wutka.jox. * ;
import java.util. * ;

public class TestBean implements java.io.Serializable
{
protected int foo;
protected String bar;
protected java.util.Date baz;
protected Vector thingies;
protected TestSubbean subbean;

public TestBean()
{
bar = "" ;
baz = new Date();
thingies = new Vector();
}

public int getFoo() { return foo; }
public void setFoo( int aFoo) { foo = aFoo; }

public String getBar() { return bar; }
public void setBar(String aBar) { bar = aBar; }

public java.util.Date getBaz() { return baz; }
public void setBaz(java.util.Date aBaz) { baz = aBaz; }

public TestSubbean getSub() { return subbean; }
public void setSub(TestSubbean aSub) { subbean = aSub; }

public String[] getThingies()
{
String[] retThingies = new String[thingies.size()];
if (thingies.size() > 0 ) thingies.copyInto(retThingies);

return retThingies;
}

public void setThingies(String[] newThingies)
{
thingies = new Vector(newThingies.length);
for ( int i = 0 ; i < newThingies.length; i ++ )
{
thingies.addElement(newThingies[i]);
}
}

public String getThingies( int i)
{
return (String) thingies.elementAt(i);
}

public void setThingies( int i, String thingy)
{
thingies.setElementAt(thingy, i);
}

public String toString()
{
StringBuffer ret = new StringBuffer(
" foo= " + foo + " ;bar= " + bar + " ;baz= " + baz.toString() +
" ;thingies= " );
for ( int i = 0 ; i < thingies.size(); i ++ )
{
if (i > 0 ) ret.append( " , " );
ret.append((String) thingies.elementAt(i));
}

ret.append( " ;sub= " );
ret.append(subbean.toString());

return ret.toString();
}
}

2.xml文件



< MarkTest >
< thingies >网
< thingies > 载
< thingies > 下
< thingies > 托
< thingies > 灵
< foo > 5
< baz > 6/25/00 12:46 AM
< bar > This is the website value
< sub >
< age > 1
< name > wangdei




下面的程序是把xml转为成javaBean
package com.wutka.jox.test;

import com.wutka.jox. * ;
import java.io. * ;

public class TestDeser
{
public static void main(String[] args)
{
try
{
FileInputStream in = new FileInputStream( " bean.xml " );

JOXBeanInputStream joxIn = new JOXBeanInputStream(in);

TestBean testBean = (TestBean) joxIn.readObject(
TestBean. class );

System.out.println(testBean);
}
catch (Exception exc)
{
exc.printStackTrace();
}
}
}



下面的程序是把javaBean转为成xml
package com.wutka.jox.test;

import com.wutka.jox. * ;
import java.io. * ;

public class TestSer
{
public static void main(String[] args)
{
try
{
TestBean b = new TestBean();
b.setFoo( 5 );
b.setBar( " This is the bar value " );
b.setThingies( new String[] {
" 网 " ,
" 载 " ,
" 下 " ,
" 托 " ,
" 灵 "
} );
TestSubbean sub = new TestSubbean();
sub.setName( " Mark " );
sub.setAge( 35 );
b.setSub(sub);

FileOutputStream fileOut = new FileOutputStream( " bean.xml " );
JOXBeanOutputStream joxOut = new JOXBeanOutputStream(fileOut);

joxOut.writeObject( " MarkTest " , b);

joxOut.close();


}
}
}
