Question

我有一个带有根元素的XML格式＆＃34; Blurb＆＃34;其中包含一组名为namespace的子元素，每个元素都有一个必需的属性＆＃34; name＆＃34;。我用xjc构建了一些类，它创建了一个包含Namespace对象列表的Blurb类。

使用命名空间名称作为键的Hash和作为值的Namespace对象对我来说似乎更方便，我开始制作XMLAdapter。使用this blog entry作为我的向导，我创建了一个适配器类并将其链接。它构建，但是当我运行它时，我得到错误，＆＃34; java.lang.AssertionError：1个IllegalAnnotationExceptions＆＃34;的计数。我已经查找了XmlJavaTypeAdapter的不同用法，但它们看起来并不一致。我已经尝试将注释放在属性，方法和两者上，并且都给了我类似的错误。有人能告诉我我做错了吗？

这是我的主要课程：

package com.jolyjonesfamily.blurb.models;

import com.jolyjonesfamily.blurb.map.adapter.BlurbMapAdapter;

import java.util.HashMap;
import java.util.Map;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "pattern",
    "namespace"
})
@XmlRootElement(name = "blurb")
public class Blurb {

    @XmlElement(required = true)
    protected Cat pattern;

    @XmlJavaTypeAdapter(BlurbMapAdapter.class)
    public Map<String, Namespace> namespace;


    // @XmlJavaTypeAdapter(BlurbMapAdapter.class)
    public Map<String, Namespace> getNamespace() {
        if (namespace == null) {
            namespace = new HashMap<String, Namespace>();
        }
        return this.namespace;
    }

    public void setNamespace(Map<String, Namespace> namespaceMap) {
        namespace = namespaceMap;
    }

    public Cat getPattern() {
        return pattern;
    }

    public void setPattern(Cat value) {
        this.pattern = value;
    }
}

这是我的适配器：

package com.jolyjonesfamily.blurb.map.adapter;

import com.jolyjonesfamily.blurb.models.Namespace;

import javax.xml.bind.annotation.adapters.XmlAdapter;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**

public class BlurbMapAdapter extends XmlAdapter<List<Namespace>, Map<String, Namespace>> {

    @Override
    public Map<String, Namespace> unmarshal(List<Namespace> namespaceList) throws Exception {
        Map<String, Namespace> namespaceMap = new HashMap<String, Namespace>();
        for(Namespace myNamespace : namespaceList) {
            namespaceMap.put(myNamespace.getName(), myNamespace);
        }
        return namespaceMap;
    }

    @Override
    public List<Namespace> marshal(Map<String, Namespace> namespaceMap) throws Exception {
        List<Namespace> result = new ArrayList<Namespace>();
        result.addAll(namespaceMap.values());
        return result;
    }
}

如果它很重要，请点击我的命名空间类：

使用XMLJavaTypeAdapter会导致IllegalAnnotationException
