Castor的简单使用

上一次的Castor是依据项目做的，现在自己做了一个小demo

一、实体类

Data

package com.yj.fenghao.castor;

public class Data {
    
    private Head head;
    private Row[] row;
    public Head getHead() {
        return head;
    }
    public void setHead(Head head) {
        this.head = head;
    }
    public Row[] getRow() {
        return row;
    }
    public void setRow(Row[] row) {
        this.row = row;
    }
    public Data(Head head, Row[] row) {
        super();
        this.head = head;
        this.row = row;
    }
    public Data() {
        super();
        // TODO Auto-generated constructor stub
    }
    
}

Head

package com.yj.fenghao.castor;

public class Head {
    
    private String name;
    private String age;
    private String sex;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getAge() {
        return age;
    }
    public void setAge(String age) {
        this.age = age;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    public Head(String name, String age, String sex) {
        super();
        this.name = name;
        this.age = age;
        this.sex = sex;
    }
    public Head() {
        super();
        // TODO Auto-generated constructor stub
    }
    

}

Row

package com.yj.fenghao.castor;

import java.util.Map;

public class Row {
    
    private String contronl;
    private Map<String,String> map;
    public String getContronl() {
        return contronl;
    }
    public void setContronl(String contronl) {
        this.contronl = contronl;
    }
    public Map<String, String> getMap() {
        return map;
    }
    public void setMap(Map<String, String> map) {
        this.map = map;
    }
    public Row(String contronl, Map<String, String> map) {
        super();
        this.contronl = contronl;
        this.map = map;
    }
    public Row() {
        super();
        // TODO Auto-generated constructor stub
    }
    
}

二、下面是映射文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN" "http://castor.org/mapping.dtd">
<mapping>
   <class name="com.yj.fenghao.castor.Data" auto-complete="true">
      <map-to xml="data"></map-to>
      <field name="head" type="com.yj.fenghao.castor.Head">
          <bind-xml name="head" node="element"></bind-xml>
      </field>
      <field name="row" collection="array" type="com.yj.fenghao.castor.Row">
          <bind-xml name="row" node="element"></bind-xml>
      </field>
   </class>
   <class name="com.yj.fenghao.castor.Head">
       <field name="name" type="string">
          <bind-xml name="name" node="element"></bind-xml>
       </field>
       <field name="age" type="string">
          <bind-xml name="age" node="element"></bind-xml>
       </field>
       <field name="sex" type="string">
          <bind-xml name="sex" node="element"></bind-xml>
       </field>
   </class>
   <class name="com.yj.fenghao.castor.Row">
       <field name="contronl" type="string">
          <bind-xml name="contronl" node="element"></bind-xml>
       </field>
       <field name="map" collection="map">
          <bind-xml name="mapitem" location="map" >
             <class name="org.exolab.castor.mapping.MapItem">
                 <field name="key" type="string">
                     <bind-xml name="key" node="attribute"></bind-xml>
                 </field>
                 <field name="value" type="string">
                     <bind-xml name="value" node="text"></bind-xml>
                 </field>
             </class>
          </bind-xml>
       </field>
   </class>
</mapping> 

三、下面是测试类

package com.yj.fenghao.castor;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.StringReader;
import java.io.UnsupportedEncodingException;
import java.net.URL;

import com.yj.fenghao.castor.Data;

import org.apache.commons.io.IOUtils;
import org.exolab.castor.mapping.Mapping;
import org.exolab.castor.mapping.MappingException;
import org.exolab.castor.xml.MarshalException;
import org.exolab.castor.xml.Unmarshaller;
import org.exolab.castor.xml.ValidationException;
import org.exolab.castor.xml.XMLContext;

public class Test {
    
    
    public static final XMLContext xml=new XMLContext();
    public static final Test test=new Test();
    public Mapping load(){
        Mapping load=new Mapping();
        try {
            URL resource = Thread.currentThread().getContextClassLoader().getResource("sample_mapping.xml");
            load.loadMapping(resource.getPath());
        } catch (IOException e) {
            e.printStackTrace();
        } catch (MappingException e) {
            e.printStackTrace();
        }
        return load;
    }
    
    public static void main(String[] args) {
        Mapping load = test.load();
        StringReader reader=null;
        String message=null;
        try {
            FileInputStream fis=new FileInputStream("d:/123.xml");
            message=new String(IOUtils.toByteArray(fis),"utf-8");
        } catch (FileNotFoundException e1) {
            e1.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            xml.addMapping(load);
            Unmarshaller unmar = xml.createUnmarshaller();
            reader=new StringReader(message);
            unmar.setClass(Data.class);
            Data data = (Data)unmar.unmarshal(reader);
            Head head = data.getHead();
            System.out.println("
"+head.getName());
            System.out.println("
"+head.getAge());
            System.out.println("
"+head.getSex());
            Row row = data.getRow()[0];
            System.out.println("
"+row.getContronl());
            System.out.println("
"+row.getMap().get("ce"));
        } catch (MappingException e) {
            e.printStackTrace();
        } catch (MarshalException e) {
            e.printStackTrace();
        } catch (ValidationException e) {
            e.printStackTrace();
        }finally{
            if(reader!=null){
                reader.close();
            }
        }
        
    }

}

只是简单的xml和实体类的映射进行数据转换
