JavaBean映射工具dozer学习

转载自http://lishaorui.iteye.com/blog/1151513
1、简介
    dozer是一种JavaBean的映射工具,类似于apache的BeanUtils。但是dozer更强大,它可以灵活的处理复杂类型之间的映射。不但可以进行简单的属性映射、复杂的类型映射、双向映射、递归映射等,并且可以通过XML配置文件进行灵活的配置。

2、准备
   现在开始就小试一下。
   首先,需要下载jar包,
   dozer.jar :http://dozer.sourceforge.net/downloading.html
   还需要slf4j.jar,commons-lang.jar,commons-beanutil.jar, commons-loggin.jar

3、代码
   两个bean
Java代码 
public class Book { 
    private String name; 
    private String author; 
 
    public String getName() { 
        return name; 
    } 
 
    public void setName(String name) { 
        this.name = name; 
    } 
 
    public String getAuthor() { 
        return author; 
    } 
 
    public void setAuthor(String author) { 
        this.author = author; 
    } 
 
    public Book() { 
    } 

  


Java代码 
   
public class BookVo { 
    private String namevo; 
    private String authorvo; 
 
    public String getNamevo() { 
        return namevo; 
    } 
 
    public void setNamevo(String namevo) { 
        this.namevo = namevo; 
    } 
 
    public String getAuthorvo() { 
        return authorvo; 
    } 
 
    public void setAuthorvo(String authorvo) { 
        this.authorvo = authorvo; 
    } 
 
    public BookVo() { 
    } 

 
 
    

  
   bookMapper.xml配置文件,用来对DozerBeanMapper进行设置。
 
Xml代码 
<?xml version="1.0" encoding="UTF-8"?> 
<mappings xmlns="http://dozer.sourceforge.net" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xsi:schemaLocation="http://dozer.sourceforge.net 
       http://dozer.sourceforge.net/schema/beanmapping.xsd"> 
        
       <mapping> 
        <class-a>test.Book</class-a> 
        <class-b>test.BookVo</class-b> 
        <field> 
            <a>name</a> 
            <b>namevo</b> 
        </field> 
        <field> 
            <a>author</a> 
            <b>authorvo</b> 
        </field> 
       </mapping> 
</mappings> 



   测试类
 
Java代码 
package test; 
 
import java.util.ArrayList; 
import java.util.List; 
 
import org.apache.commons.logging.Log; 
import org.apache.commons.logging.LogFactory; 
import org.dozer.DozerBeanMapper; 
 
/**
* 说明:

* @author lsr
* @version Aug 17, 2011
*/ 
public class DozerTest { 
    /**
     * @param args
     */ 
    public static void main(String[] args) { 
        testByXml(); 
    } 
     
    public static void testByXml() { 
        Book book = new Book(); 
        book.setAuthor("lsr"); 
        book.setName("dozer demo"); 
        DozerBeanMapper mapper = new DozerBeanMapper(); 
        List<String> mappers = new ArrayList<String>(); 
        mappers.add("bookMapper.xml"); 
        mapper.setMappingFiles(mappers); 
        BookVo vo = new BookVo(); 
        mapper.map(book, vo); 
        System.out.println("book's name:" + book.getName()); 
        System.out.println("bookVo's name:" + vo.getNamevo()); 
    }
