dozer-初識

http://lishaorui.iteye.com/blog/1151513

1、簡介 

    dozer是一種JavaBean的映射工具，類似於apache的BeanUtils。但是dozer更強大，它可以靈活的處理複雜類型之間的映射。不但可以進行簡單的屬性映射、複雜的類型映射、雙向映射、遞歸映射等，並且可以通過XML配置文件進行靈活的配置。 

2、準備 
   現在開始就小試一下。 
   首先，需要下載jar包， 
   dozer.jar :http://dozer.sourceforge.net/downloading.html 
   還需要slf4j.jar，commons-lang.jar,commons-beanutil.jar, commons-loggin.jar 

3、代碼 
   兩個bean 

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() {
    }
}

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，用來對DozerBeanMapper進行設置。 
  

<?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>

   測試類 
  

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;

/**
 * 說明：
 *
 * @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());
    }

}
