我尝试从文件中创建响应来测试elasticsearch服务

def "FounderHint"() {
        setup:
        URL url = getClass().getClassLoader().getResource("elastic_response/elastic-founders-hint-response.json")
        SearchResponse response = new SearchResponse().readFrom(url.openStream())  // this is a 40 line error

        when: "we ask for hint"
        elasticClient.search(any()) >> response
        metrics.measureHintSearchTime(_) >> response

        then: "we get list of ObjectHint"
        List<ObjectHint> result = advancedSearchFilter.founderHint("але").collect(Collectors.toList())

        result[0].inn == "323500905646"
        result[0].name == "Алешина Екатерина Леонидовна"

但我犯了个错误-

No signature of method: org.elasticsearch.action.search.SearchResponse.readFrom() is applicable for argument types: (java.io.BufferedInputStream) values: [java.io.BufferedInputStream@19f135ca]
Possible solutions: readFrom(org.elasticsearch.common.io.stream.StreamInput), readFrom(org.elasticsearch.common.io.stream.StreamInput), readFrom(org.elasticsearch.common.io.stream.StreamInput)

searchresponse是一个类elasticsearch，它没有setter，是否有其他方法来创建响应或者我在哪里犯了错误？
