import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.io.StringWriter;

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

                marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);// 默认false表示xml指令存在

import java.util.List;

import com.jx.aisino.util.JaxbUtils;

import model.ContentElement;
import model.XmlModel;

public class TestJaxbUtils {

    public static void main(String[] args) {
try {
            //对象转换xml
            XmlModel model = new XmlModel();
            ContentElement contentElement = new ContentElement();
            contentElement.setContent1("66+46546");
            contentElement.setContent2("232131");
            model.setData("测试");
            List<ContentElement> cList = new ArrayList<>();
            cList.add(contentElement);
            model.setContent(cList);
            model.setTest(" 2132132 ");
            String reqs = JaxbUtils.getXmlByObject(model);
            System.out.println("请求报文："+reqs);
            //xml转换对象
            XmlModel model2 = (XmlModel)JaxbUtils.toPojo(reqs, XmlModel.class);
            System.out.println(model2.toString());
        }catch(Exception exception){
            System.out.println("出错");
        }

    }
