Question

我正在使用最新的JMeter 4并尝试在jexl syntax中使用声明局部变量的基本jexl function

局部变量可以使用var关键字定义;他们的识别规则与上下文变量相同。基本声明：var x;

所以在JMeter中我试过

${__jexl2(var x;)}

并且成功了，但是使用${__jexl3(var x;)}会抛出一个解析器异常：

是JMeter问题还是jexl3问题，还是我错过了什么？

修改

除了解析var失败之外，它无法解析;，这是jexl2失败的jexl2的工作示例：

${__jexl3(abc=new("java.util.ArrayList"\, 1);)}

Answer 1

根据bug，它是JMeter Jexl3实现中的jexl issue：

JMeter使用JexlExpression代替JexlScript

错误现已修复，将在下一个版本上载

JMeter - jexl3函数不能声明局部变量
