Question

我想在Elasticsearch中执行单元测试，因为我正在使用public class DateTimeRange { private DateTime Start { get; set; } private DateTime End { get; set; } public DateTimeRange(DateTime start, DateTime end) { Start = start; End = end; } public int DayOffsCount() { var current = Start; var dayOffsCount = 0; while (current < End) { if (IsDayOff(current)) { dayOffsCount++; } current = current.AddDays(1); } return dayOffsCount; } } public bool IsDayOff(DateTime dt) { if (dt.DayOfWeek == DayOfWeek.Saturday || dt.DayOfWeek == DayOfWeek.Sunday) return true; return IsHoliday(dt); }
我正在使用Java-test-framework 并参考这些链接寻求帮助 https://www.elastic.co/guide/en/elasticsearch/reference/1.6/using-elasticsearch-test-classes.html https://github.com/elastic/elasticsearch/blob/master/core/src/test/java/org/elasticsearch/action/search/SearchRequestBuilderTests.java

这是代码

Elasticsearch-1.6.0

我收到此异常

class CampaignESTest extends ESTestCase {

  def getCLient():MockTransportClient={
     val settings = Settings.builder()
                .put(Environment.PATH_HOME_SETTING.getKey(), Files.createTempDir().toString())
                .build();
     val client = new MockTransportClient(settings);  
     client
  }
 }

class CampaignTestSearch extends PlaySpec{
  val client=new CampaignESTest

val response = client.prepareSearch("dbtest")
      .setTypes(CAMPAIGN_COLLECTION_NAME)
      .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
      .addFields("uuid","campaignName","artworkID","activationDate","_source")
      .setQuery(query)
      .execute()
      .actionGet()
  }

在此行中获得例外

课程

val client=new CampaignESTest

中的

这是CampaignTestSearch文件

中的依赖项

build.sbt

我怀疑异常的原因可能是由于某些版本的依赖项，任何人都可以帮助使用正确的库依赖版本来使其工作或者是我缺少的其他东西

两个问题：

SimpleTextCodec位于codecs，而不是后退编解码器。
您正在使用lucene 5.4.0中的jar。切勿混合搭配你的lucene版本。 Elasticsearch 1.6.0旨在与lucene 4.10.4一起使用。在lucene 5.4.0的罐子里混合只会给你带来麻烦。

java.lang.NoClassDefFoundError：org / apache / lucene / codecs / simpletext / SimpleTextCodec
