Question

我添加了@QueryParam作为我的REST注释的一部分但是当我与swagger集成时，它会在生成swagger JSON时导致以下错误：

任何人都知道如何解决？这是依赖性错误吗？

我正在使用swagger com.wordnik swagger-jersey2-jaxrs 1.5.1-M2版本。有什么想法吗？

其他方法细节

    @GET
    @Path("/stuff/test")
    @ApiOperation(value = "Get some data", notes = "Returns some data", response = Existing.class, responseContainer = "List")
    @ApiResponses(value = { @ApiResponse(code = 404, message = "some error message") })
    @Timed
    public Response getData(
            @ApiParam(value = "filter", required = false, name = "filter") @QueryParam("filter") Optional<String> filterParam)
            throws Exception {
//codes here
}

当我忘记在Application.run方法中添加以下映射细节时，我遇到了类似的错误：

"Nixon":[{"approvalRating": 10, "suitColor":"blue", "firstName":"Richard"}]

如果没有此设置，空值的映射将失败，这可能与您的Optional相对应。

这似乎是从1.3迁移到1.5的回归。我们过去曾处理过try (BufferedInputStream bStream = httpGateway.loadContents()) { cachedContent = xmlParser.parseVideos(bStream); }，但可能会让转换失败。

你现在能做的最好的事情就是在swagger-core上打开一个问题。
