我在Rest服务中有两种方法：
@Path("judgements")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public interface JudgementsService {
@POST
@Path("get1")
@Consumes(MediaType.APPLICATION_JSON)
void test(Set<Query> param) throws IOException;
@POST
@Path("get")
Map<Query, JudgementsForQuery> getJudgementsForQueries(
@Multipart(value = "queries", type = MediaType.APPLICATION_JSON) Set<Query> queries,
@Multipart(value = "regional", type = MediaType.APPLICATION_JSON) RegionalType regionalType,
@Multipart(value = "evaluation", type = MediaType.APPLICATION_JSON) EvaluationType evaluationType) throws IOException;
方法test（）工作正常，方法getJudgementsForQueries（）抛出异常：

由于某些原因似乎json打包成多部分消息并没有正确地映射到集合......
任何帮助表示赞赏!!
