}

二、解析工具代码

package cn.com.songjy.test.xml.xstream;

import java.io.IOException;
import java.io.InputStream;

import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;

public class XstreamUtil {

	public static <T> T XML2Bean(InputStream input, Class<T> clazz)
			throws IOException {

		XStream xstream = new XStream(new DomDriver());

		xstream.processAnnotations(clazz);

		return (T) xstream.fromXML(input);
	}
}

三、XML示例文件alipay.xml

<alipay>
	<is_success>T</is_success>
	<request>
		<param name="_input_charset">utf-8</param>
		<param name="service">single_trade_query</param>
		<param name="partner">20889010000000</param>
		<param name="out_trade_no">7_20130223150319_26</param>
	</request>
	<response>
		<trade>
			<body>北京-7_20130223150319_26</body>
			<buyer_email>[e-mail]</buyer_email>
			<buyer_id>208812311290894</buyer_id>
			<coupon_used_fee>0.00</coupon_used_fee>
			<discount>0.00</discount>
			<flag_trade_locked>0</flag_trade_locked>
			<gmt_create>2013-02-17 15:04:58</gmt_create>
			<gmt_last_modified_time>
				2013-02-17 15:05:09
			</gmt_last_modified_time>
			<gmt_payment>2013-02-17 15:05:09</gmt_payment>
			<is_total_fee_adjust>F</is_total_fee_adjust>
			<operator_role>B</operator_role>
			<out_trade_no>7_20130223150319_26</out_trade_no>
			<payment_type>1</payment_type>
			<price>0.01</price>
			<quantity>1</quantity>
			<seller_email>[e-mail]</seller_email>
			<seller_id>2088901059369309</seller_id>
			<subject>北京-7_20130223150319_26</subject>
			<to_buyer_fee>0.00</to_buyer_fee>
			<to_seller_fee>0.01</to_seller_fee>
			<total_fee>0.01</total_fee>
			<trade_no>2013022356736989</trade_no>
			<trade_status>TRADE_SUCCESS</trade_status>
			<use_coupon>F</use_coupon>
		</trade>
	</response>
	<sign>6c472babf7bd98ascb97fee1666a3303</sign>
	<sign_type>MD5</sign_type>
</alipay>

或

<alipay>
	<is_success>F</is_success>
	<error>xxxx</error>
</alipay>

四、测试

public void test() {
		Alipay alipay = null;
		try {
			alipay = XstreamUtil.XML2Bean(new FileInputStream("alipay.xml"),
					Alipay.class);
		} catch (IOException e) {
			e.printStackTrace();
		}
		System.out.println(alipay.getIsSuccess());
		System.out.println(alipay.getRequest().getParam().get(0).getContent());
	}
