Spring Cloud Openfeign “;” isn't treated as "/;" in Spring Cloud Openfeign client

Hi there, I am facing a weird problem in my project. Here is the scenario. There are service a and service b, and a -> b by feign client.

When calling http://localhost:8080/feign?test=1&a=1;1, feign client treated "a=1;1" as "a=1&a=1" and it occurs in 10.X of Spring Cloud Openfeign which works well in 9.X.

Can someone help to look into this problem?
