xml报文demo

<?xml version="1.0" encoding="UTF-8"?>
<ROOT>
	<ITEM>
		<XXXX></XXXX>
		...
	</ITEM>
	<ITEM>
		<XXXX></XXXX>
		...
	</ITEM>
</ROOT>

首先写一个XmlUtil工具类

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

public class XmlUtil{
	
	public static <T> T convertXmlStrToObject(Class<?> clazz,String xmlStr){
		T xmlObject = null;
		try{
			JAXBContext context = JAXBContext.newInstance(clazz);
			Unmarshaller unmarshaller = context.createUnmarshaller();
			xmlObject = (T) unmarshaller.unmarshal(new StringReader(xmlStr));
		} catch (Exception e){
			log.error("将报文转换为object失败:{}",e.getMessage());
		}

		return xmlObject;
	}
}

你需要转化的类

@Data
@XmlRootElement(name = "ROOT")
public class XXXRoot{
	private List<XXX> ITEM;
}

ITEM对应了 < ITEM > 标签，如果要起别名可以试试@XmlElement(name = “ITEM”)我没试过，具体效果自己看吧

@XmlAccessorType(XmlAccessType.FIELD)
@Data
public class XXX implements Serializable{
	@XmlElement(name="yyy")
	private String yy;

	.....
}

使用的时候，XXXRoot ddd = XmlUtil.convertXmlStrToObject(XXXRoot.class,xmlbaowenstring);
