xml与javaBean的互相转化

1.学会使用xml的各个注解与含义，参考网址如下 /article/11526372.html

举例：

</pre><pre name="code" class="java">@XmlRootElement(name="RequestOrder")
@XmlType(propOrder={"clientFlag","orderNo","subOrderNo","tradeNo","mailNo","type","flag","sender","receiver","sendStartTime","sendEndTime","codAmount",
"items","insuranceValue","loadRequire","remark","dataFlag"})
@XmlAccessorType(XmlAccessType.FIELD)
public class OrderRequest {

/**客户标示**/
@XmlElement(name="logisticProviderID")
private String clientFlag;
/** 客户单号**/
private String orderNo;
/** 子订单业号**/
private String subOrderNo;
/** 业务交易号**/
private String tradeNo;
/** 快递单号**/
private String mailNo;
/** 类型 代收订单0 普通正向 1 退货订单 2 **/
private Integer type;
/** 订单标示 0 **/
private Integer flag;
/** 寄件人 **/
private PersonInfo sender;
/** 收件人 **/
private PersonInfo receiver;
/** 物流上门取货时间段 **/
private String sendStartTime;
private String sendEndTime;
/** 代收金额**/
private double codAmount;
/** 商品信息 **/
@XmlElementWrapper(name="items")
@XmlElement(name="item")
private List<ZJSOrderItems> items;
/** 保险费**/
private double insuranceValue;
/** 配载要求：无/禁航/禁航铁 **/
private String loadRequire;
/** 重要提示 **/
private String remark;
/** 数据标示 （用于分仓发货，C2C类客户省略） **/
private String dataFlag;
//构造方法
//getter与setter方法
}

2.编写JaxUtil类，方便进行xmlTobean与beanToXml的转化

public class JaxbUtil {

/** The logger. */
private static final Log LOGGER = LogFactory.getLog(JaxbUtil.class);

/**
* JavaBean转换成xml 默认编码UTF-8
*
* @param obj
* @param writer
* @return
*/
public static String convertToXml(Object obj) {
return convertToXml(obj, "UTF-8");
}

/**
* JavaBean转换成xml
*
* @param obj
* @param encoding
* @return
*/
public static String convertToXml(Object obj, String encoding) {
String result = null;
try {
JAXBContext context = JAXBContext.newInstance(obj.getClass());
Marshaller marshaller = context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
marshaller.setProperty(Marshaller.JAXB_ENCODING, encoding);

StringWriter writer = new StringWriter();
marshaller.marshal(obj, writer);
String xmlTitle = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
result = xmlTitle + writer.toString();
} catch (Exception e) {
LOGGER.error("convertToXml has error,", e);
}

return result;
}

/**
* xml转换成JavaBean
*
* @param xml
* @param c
* @return
*/
@SuppressWarnings("unchecked")
public static <T> T converyToJavaBean(String xml, Class<T> c) {
T t = null;
try {
JAXBContext context = JAXBContext.newInstance(c);
Unmarshaller unmarshaller = context.createUnmarshaller();
<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"></span><pre code_snippet_id="1656191" snippet_file_name="blog_20160421_2_9698971" name="code" class="java"><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"><span style="white-space:pre">				</span>xml=xml.replaceAll("<", "<");</span>

xml=xml.replaceAll(">", ">");

xml=xml.replace("<string xmlns=\"http://edi.zjs.com.cn/\"><?xml version=\"1.0\" encoding=\"utf-8\" ?>", "");

xml=responseData.replace("</string>", "");

<span style="white-space:pre">		</span>t = (T) unmarshaller.unmarshal(new StringReader(xml));
} catch (Exception e) {
LOGGER.error("converyToJavaBean has error,", e);
}
return t;
}

}
