JAXB unmarshal不适用于JDK 1.6

本文介绍了JAXB unmarshal不适用于JDK 1.6的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

是的，这是一个长期无聊的问题，可能同时非常简单。 :(

Yes, this is a long boring posted question which is maybe very simple at the same time. :(

我只是调用从Java平台实现的SOAP WebService接口。收到数据后，使用JAXB将其转换为java对象。所有东西都适用于JDK1 .8，但是JDK1.6失败

I just calling a SOAP WebService interface implemented with .NET platform from Java. After the data received, converting it to java objects using JAXB.Everything works well with JDK1.8, but failed with JDK1.6

我注意到解组过程在GetBjxsDataResponse级别停止。即我可以从包络体中成功获得GetBjxsDataResponse的实例，但是实例的getBjxsDataResult成员是null。

I noticed that the unmarshalling process stopped at the GetBjxsDataResponse level. Namely I could successfully got an instance of GetBjxsDataResponse from the envelop body, but the getBjxsDataResult member of the instance is null.

这是否与JAXB RI版本有关？我是java世界的新手。需要你的帮助！ ：）

Is this have something to do with the JAXB RI version? I'm a newbie to java world. Need your help! :)

NamespaceMapper.java

        JAXBContext jaxbContext2 =JAXBContext.newInstance(

        InputStream is = new ByteArrayInputStream(str.getBytes());
        Unmarshaller unmarshaller = jaxbContext2.createUnmarshaller();
        Envelope responseEnvelope = (Envelope)unmarshaller.unmarshal(is);

        GetBjxsDataResponse getBjxsDataResponse =
            (GetBjxsDataResponse)responseEnvelope.getBody().getMethod();

        @SuppressWarnings("unchecked")
        List<Object> bjxsDatas = (List<Object>)getBjxsDataResponse.getValuableData();
        System.out.println(bjxsDatas.size());
    }
}


推荐答案

最后，我选择通过和tu通过将结果发送到Java对象实例。

Finally I choose to parse the XML-format response by JAXM api and turn the result to Java object instance by Java reflection.

这篇关于JAXB unmarshal不适用于JDK 1.6的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
