This parameter is not supported in v2.1.1.RELEASE. You may refer to #1213 (comment)

[sczyh30]

Actually the newer versions do not support it as well, because it has not been supported yet in sentinel-spring-webmvc-adapter. Refer #1314

[sczyh30]

This has been supported in #1328 by @cdfive. This will also be supported in Spring Cloud Alibaba later. @fangjian0423
