我的客户代码

@覆盖 public List getAllFunctions（）{

Response response = null;
try {

    response = super.get(this.targetServiceUrl + WSPath.GET_ALL_FUNCTIONS);
    List<Function> functions  =
            response.readEntity(new GenericType<List<Function>>() {});
    return functions;
} catch (Exception e) {

    throw new InternalServerErrorException(e);
} finally {

    response.close();
}

}

我的网络服务代码

@Component
@Produces(MediaType.APPLICATION_JSON)
@Path(WSPath.MISCELLANEOUS_SERVICE)
public class MiscellaneousResource {

    @Autowired
    private MiscellaneousService miscellaneousService;

    @Autowired
    private InstrumentService instrumentService;
    @GET
    @Path(WSPath.GET_ALL_FUNCTIONS)
    public Response getAllFunctions() {

        List<Function> functions = miscellaneousService.getAllFunctions();
        return Response.ok(functions).build();
    }
}

请帮我克服这个异常
