JaxB unmarshal自定义xml [英] JaxB unmarshal custom xml

问题描述

我目前正在尝试将一些现有的XML解组为我手工创建的几个类。问题是，我总是得到一个错误，告诉我，JaxB期望一个天气元素，但找到一个天气元素。 （？）

I'm currently attempting to unmarshal some existing XML into a few classes I have created by hand. Problem is, I always get an error that tells me, JaxB expects a weather element but finds a weather element. (?)

javax.xml.bind.UnmarshalException：意外元素（uri：http://www.aws.com/aws ，当地：天气）。预期元素为< {} api>，< {} location>，< {} weather>

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.aws.com/aws", local:"weather"). Expected elements are <{}api>,<{}location>,<{}weather>

我试过和元素名称中没有aws：。

I tried with and without "aws:" in the elements' name.

这是我的天气等级：

@XmlRootElement(name = "aws:weather")
public class WeatherBugWeather
{
    private WeatherBugApi api;
    private List<WeatherBugLocation> locations;
    private String uri;

    @XmlElement(name="aws:api")
    public WeatherBugApi getApi()
    {
        return this.api;
    }

    @XmlElementWrapper(name = "aws:locations")
    @XmlElement(name = "aws:location")
    public List<WeatherBugLocation> getLocations()
    {
        return this.locations;
    }

    public void setApi(WeatherBugApi api)
    {
        this.api = api;
    }

    public void setLocations(List<WeatherBugLocation> locations)
    {
        this.locations = locations;
    }

    @XmlAttribute(name="xmlns:aws")
    public String getUri()
    {
        return this.uri;
    }

    public void setUri(String uri)
    {
        this.uri = uri;
    }
}

这就是我尝试解析的XML：

And that's the XML I try to parse:

<?xml version="1.0" encoding="utf-8"?>
<aws:weather xmlns:aws="http://www.aws.com/aws">
    <aws:api version="2.0" />
    <aws:locations>
        <aws:location cityname="Jena" statename="" countryname="Germany" zipcode="" citycode="59047" citytype="1" />
    </aws:locations>
</aws:weather>

我不太确定我做错了什么。任何提示？我怀疑问题是xmlns定义，但我不知道如何处理它。 （你可以通过查看uri-property看到这一点。这是一个不成功的想法。^^）是的，我确实尝试设置命名空间，而是设置命名空间的uri而不是它的... name。

I'm not quite sure what I'm doing wrong. Any hints? I suspect the problem to be the xmlns definition, but I have no idea what to do about it. (You can see that by looking at the uri-property. That was one unsuccessful idea. ^^) And yes, I did try to set the namespace but that rather set's the namespace's uri instead of it's ... name.

推荐答案

您需要在代码中使用命名空间。名称空间前缀没有意义，你需要实际的名称空间（即http://www.aws.com/aws）。

you need namespaces in your code. namespace prefixes are meaningless, you need the actual namespace (i.e. "http://www.aws.com/aws").

@XmlRootElement(name = "weather", namespace="http://www.aws.com/aws")
