【Java】Java对象和XML相互转换（序列化）

概述

类需要实现Serializable接口

需要使用XStream，Maven依赖：

<dependency>
			<groupId>com.thoughtworks.xstream</groupId>
			<artifactId>xstream</artifactId>
			<version>1.4.9</version>
</dependency>

XMLUtils

/**

 * <dependency>
 *     <groupId>com.thoughtworks.xstream</groupId>
 *     <artifactId>xstream</artifactId>
 *     <version>1.4.9</version>
 * </dependency>
 */
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;

public class XMLUtils {

    /**

     * 
     * @param clazz

        XStream xStream = new XStream(new DomDriver());
        xStream.alias(clazz.getSimpleName(), clazz);

        String xml = xStream.toXML(object);
        return xml;
    }

    /**
