如何把soap xml string转对象，里面带有&lt等转义符

如何把soap xml string转对象，里面带有<等转义符

xml如图下，要把caseCode后的提取为对象

   
      
         
            
               <Header>UWBCDtResponse</Header><Type>string</Type><Return>{\"caseCode\":\"abc\",\"bagList\":[{\"reelList\":[],\"bagCode\":\"12\",\"qty\":78000.0},{\"reelList\":[],\"bagCode\":\"123\",\"qty\":78000.0},{\"reelList\":[],\"bagCode\":\"1234\",\"qty\":78000.0},{\"reelList\":[],\"bagCode\":\"12345\",\"qty\":78000.0},{\"reelList\":[],\"bagCode\":\"123456\",\"qty\":78000.0},{\"reelList\":[],\"bagCode\":\"123456\",\"qty\":78000.0},{\"reelList\":[],\"bagCode\":\"1234567\",\"qty\":78000.0}]}</Return><Tailer>UWBCEnd</Tailer>
            

对象:

public class EcsBarcodeVo implements Serializable {

    private static final long serialVersionUID = 1L;

    @XmlAttribute
    private String caseCode;

    @XmlAttribute
    private List bagList;

    private class BagList{

        private List<String> reelList;

        private String bagCode;

        private BigDecimal qty;
}

个人是参考这里的方法写了个，

public Object conver(String clazz) throws XMLStreamException, JAXBException {
        Reader reader = new StringReader(clazz);
        XMLInputFactory factory = XMLInputFactory.newInstance(); // Or newFactory()
        XMLStreamReader xsr = factory.createXMLStreamReader(reader);
        xsr.nextTag();
        while(!xsr.getLocalName().equals("return")) {
            xsr.nextTag();
        }
        JAXBContext jc = JAXBContext.newInstance(EcsBarcodeVo.class);
        Unmarshaller unmarshaller = jc.createUnmarshaller();
        JAXBElement jb = unmarshaller.unmarshal(xsr, EcsBarcodeVo.class);
        xsr.close();

        EcsBarcodeVo customer = jb.getValue();
        System.out.println(customer.getCaseCode());
        System.out.println(customer.getBagList());
        return null;
    }

但是不知道是不是有转义符的原因，报错Message: found: CHARACTERS, expected START_ELEMENT or END_ELEMENT

求人帮忙解答下如何才能转对象
