这是一个揭示想法的解决方案：
public class JacksonSerializer { public static final String INPUT = "{n" + " "menu": [n" + " {n" + " "1": "sql",n" + " "2": "android",n" + " "3": "mvc"n" + " }n" + " ]n" + "}"; public static class MenuItems { Map<String, String> menu = Maps.newHashMap(); } public static class MenuItemsDeserializer extends JsonDeserializer<MenuItems> { @Override public MenuItems deserialize(org.prehaus.jackson.JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException { JsonNode node = jsonParser.getCodec().readTree(jsonParser); final JsonNode elems = node.getElements().next().getElements().next(); final Map<String, String> map = Maps.newHashMap(); final Iterator<Map.Entry<String, JsonNode>> it = elems.getFields(); while (it.hasNext()) { final Map.Entry<String, JsonNode> entry = it.next(); map.put(entry.getKey(), entry.getValue().asText()); } final MenuItems menuItems = new MenuItems(); menuItems.menu = map; return menuItems; } } public static void main(final String[] args) throws IOException { ObjectMapper mapper = new ObjectMapper(); SimpleModule module = new SimpleModule("SimpleModule", new Version(1,0,0,null)); module.addDeserializer(MenuItems.class, new MenuItemsDeserializer()); mapper.registerModule(module); MenuItems menuItems = mapper.readValue(INPUT, MenuItems.class); }}
