elasticsearchを使用したGroovyプログラミング

Question

groovyの新機能です。私はelasticsearchウォッチャー状態で使用される単純なプログラムを書いたが、ログステートメントの後には例外MissingMethodExceptionが得られている。

FOR IN

def thres = ${threshold} 
println "${ctx.payload.hits.hits[0]._score}" 
def result = false 
def score = ${hit._score} 


for(hit in ctx.payload.hits.hits){ 
    println "FOR IN" 
    if (${score} > ${thres}) { 
    println "Inside Condition IF" 
    result = true 
    } 
}

"条件"：{ "スクリプト"：{ "ファイル"： "validateScore"、 "langの"： "かっこいい"、 "paramsは"： { "閾値"：1.09}}} 、

Answer 1

スクリプト内の変数としてthresとscoreを定義するとして、あなたがする必要はありません

if (score > thres)

で if (${score} > ${thres})を置き換え、それらの値を取得するために ${}フォームを使用します
