groovy脚本转painless语法总结
在Painless中,可以使用split()函数将逗号分隔的字符串转换为数组。
下面是一个示例代码:
```
String tagsString = "tag1,tag2,tag3";
List<String> tagsList = Arrays.asList(tagsString.split(","));
```
在上述代码中,我们首先定义一个逗号分隔的字符串`tagsString`,然后使用`split()`函数将其转换为字符串数组,并将结果转换为`List`类型的`tagsList`。
注意,Painless中的数组是动态类型的,因此无需明确指定数组长度。
希望这可以帮助到你!<span class="em">1</span><span class="em">2</span><span class="em">3</span>
