groovy - ElasticSearch 1.5升级:JodaTime转换脚本错误

Question

我正在努力将ElasticSearch版本从1.3升级到1.5。我们大量使用Java API。 ES查询中的以下脚本:

 {
  "script" : {
    "script" : "values contains (int)doc['timestamp'].date.toDateTime(DateTimeZone.forID('America/New_York')).getMonthOfYear()",
    "params" : {
      "values" : [ 1 ]
    },
    "lang" : "groovy"
  }
}

这适用于1.3，但在1.5中给出以下错误:

org.elasticsearch.action.search.SearchPhaseExecutionException: Failed to execute phase [query_fetch], all shards failed; shardFailures {[XwOu9zq0TMi2uOptdfIS7w][eventdata][0]: QueryPhaseExecutionException[[eventdata][0]: query[filtered(ConstantScore(ScriptFilter(values contains (int)doc['timestamp'].date.toDateTime(DateTimeZone.forID('America/New_York')).getMonthOfYear().toString())))->cache(org.elasticsearch.index.search.nested.NonNestedDocsFilter@2a8c0465)],from[0],size[10]: Query Failed [Failed to execute main query]]; nested: GroovyScriptExecutionException[MissingMethodException[No signature of method: Script1.contains() is applicable for argument types: (java.lang.Class) values: [int]

解决此问题的最佳方法是什么？

Answer 1

这看起来像是强制转换的括号问题，因此它认为您正在将int传递给contains。尝试添加方括号以帮助解析器:

values.contains((int)doc['timestamp'].date.toDateTime(DateTimeZone.forID('Ameri‌​ca/New_York')).getMonthOfYear())
