JAXBTool工具(实现Java对象与xml的互转)

JAXBTool工具,可以将对象转换为xml,也可将xml转换成对象

代码:

import java.io.StringReader;
import java.io.StringWriter;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;

public class JAXBTool {

	/**
	 * 使用SUN公司提供Marshaller
	 * 
	 * Marshaller是jdk1.6中自带的xml解析器(它可以完成XML的字符串,与JAVA对象之间的互转)
	 * @param cls
	 * @param obj
	 * @return
	 * @throws JAXBException 
	 */
	public static  String java2Xml(Class cls,Object obj) throws JAXBException {
		JAXBContext context = JAXBContext.newInstance(cls);
		Marshaller marsheller = context.createMarshaller();//得到XML的解析器
		marsheller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
		StringWriter writer = new StringWriter();
		marsheller.marshal(obj, writer);//使用XML的解析器,完成对象的xml解析
		return writer.toString();
	} 
	
	/**
	 * 使用SUN公司提供Marshaller
	 * 完成XML格式的数据,反序列化为Java对象
	 * @param cls
	 * @param content
	 * @return
	 * @throws JAXBException 
	 */
	public static  Object xml2Java(Class cls,String content) throws JAXBException {
		JAXBContext context = JAXBContext.newInstance(cls);
		Unmarshaller unmarsheller = context.createUnmarshaller();//XML格式的反解析类
		StringReader reader = new StringReader(content);
		return unmarsheller.unmarshal(reader);
	}	
	
}
