CXF @WebService 传递 MAp类型对象

使用CXF的EndPoint发布WebService报异常：

... 14 more是在Service创建一个方法，服务端返回一个Map对象给客户端。自定义了服务端的接口，对这个函数的定义为：

@XmlJavaTypeAdapter(MapAdapter.class)
public Map<String, String> getPersonMap();
上面注解中的MapAdapter是自定义的传唤工具，代码为：
 
public class MapAdapter extends XmlAdapter<MapConvertor, Map<String, Object>> {
    @Override
    public MapConvertor marshal(Map<String, Object> map) throws Exception {
        MapConvertor convertor = new MapConvertor();
        for (Map.Entry<String, Object> entry : map.entrySet()) {
            MapConvertor.MapEntry e = new MapConvertor.MapEntry(entry);
            convertor.addEntry(e);
        }
        return convertor;
    }
 
    @Override
    public Map<String, Object> unmarshal(MapConvertor map) throws Exception {
        Map<String, Object> result = new HashMap<String, Object>();
        for (MapConvertor.MapEntry e : map.getEntries()) {
            result.put(e.getKey(), e.getValue());
        }
        return result;
    }
}

其中使用的MapConvertor定义为：
 
@XmlType(name = "MapConvertor")
@XmlAccessorType(XmlAccessType.FIELD)
public class MapConvertor {
    private List<MapEntry> entries = new ArrayList<MapEntry>();
 
    public void addEntry(MapEntry entry) {
        entries.add(entry);
    }
 
    public List<MapEntry> getEntries() {
        return entries;
    }
     
    public static class MapEntry {
 
        private String key;
 
        private Object value;
         
        public MapEntry() {
            super();
        }
 
        public MapEntry(Map.Entry<String, Object> entry) {
            super();
            this.key = entry.getKey();
            this.value = entry.getValue();
        }
 
        public MapEntry(String key, Object value) {
            super();
            this.key = key;
            this.value = value;
        }
 
        public String getKey() {
            return key;
        }
 
        public void setKey(String key) {
            this.key = key;
        }
 
        public Object getValue() {
            return value;
        }
 
        public void setValue(Object value) {
            this.value = value;
        }
    }
}
这样发布这个服务就报异常了。请问，这种自定义CXF里WebService对象传输的转换类，应该如何定义呢？
