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());
}

}
