事件推送群发结果,获取后转换为xml文件时报错,

事件推送群发结果,获取HttpServletRequest转换为xml文件时,将HttpServletRequest形式为xml文件的字符串时String requestXml = MessageUtil.parse2Xml(request);),获取的字符串为:

<xml><ToUserName>ToUserName><FromUserName>FromUserName><CreateTime>1571039189CreateTime><MsgType>MsgType><Event>Event><MsgID>3147483669MsgID><Status>Status><TotalCount>2TotalCount><FilterCount>2FilterCount><SentCount>2SentCount><ErrorCount>0ErrorCount>
<CopyrightCheckResult>
    <Count>0Count>
    <ResultList>
    ResultList>
    <CheckState>1CheckState>
CopyrightCheckResult>
<ArticleUrlResult>
    <Count>1Count>
    <ResultList>
        <item>
            <ArticleIdx>1ArticleIdx>
            <ArticleUrl>ArticleUrl>
        item>
    ResultList>
ArticleUrlResult>
xml>

发现 -> -> 的item项为小写开头的i,所以在之后将形式为xml的字符串解析为相应对象时出错,

ReqBaseMessage reqBaseMessage = parseWechatMessage(requestXml);
 
reqBaseMessage = convertResult(requestXml, ReqEventMessage.class, ReqBaseMessage.class);
 
@SuppressWarnings("unchecked")
    private T convertResult(String result, Class clazz, Class parentClazz) {
        XStream xStream = new XStream();
        xStream.addDefaultImplementation(clazz, parentClazz);
        xStream.autodetectAnnotations(true);
        xStream.processAnnotations(clazz);
        Object transaction = xStream.fromXML(result);
        return (T)transaction;
    }
    

对应的类为:

    经过结合上网查找,发现只需将对应的Item类前加上对应@XStreamAlias("item")注解就行了,谢谢啦。
