在ElasticSearch 5.2.1中从groovy脚本迁移到无痛苦脚本

Question

我一直使用groovy脚本作为ScriptType.File。我的groovy脚本的一部分如下所示。

def refApplicValues =_source.refApplicValue;
def lineNumbers = refApplicValues.tokenize('|');

现在，我正在迁移到使用无痛脚本的ElasticSearch 5.2.1。我对我的脚本进行了一些修改，以匹配无痛语法，例如：

def refApplicValues =params._source.refApplicValue;
def lineNumbers = refApplicValues.tokenize('|');

当我现在运行我的脚本时，它抛出了运行时错误：

Caused by: QueryPhaseExecutionException[Query Failed [Failed to execute main query]]; nested: ScriptException[runtime error]; nested: IllegalArgumentException[Unable to find dynamic method [tokenize] with [1] arguments for class [java.lang.String].];

它告诉我我不能使用tokenize。有没有什么相关的功能可以替代？

您可以在无痛环境中使用StringTokenizer
