• It is recommended to use the [OGNL] (https://arthas.aliyun.com/doc/arthas-tutorials.html?language=en&id=command-ognl) command, which will be more flexible.

Check the static fields of classes conveniently, the usage is getstatic class_name field_name.

getstatic demo.MathGame random{{execute T2}}

]

Tip: if the static field is a complex class, you can even use OGNL to traverse, filter and access the inner properties of this class.
