包路径：feign.Util
类名称：Util
方法名：resolveLastTypeParameter

Util.resolveLastTypeParameter介绍

[英]Resolves the last type parameter of the parameterized supertype, based on the genericContext, into its upper bounds.

Implementation copied from retrofit.RestMethodInfo.
[中]基于genericContext将参数化超类型的最后一个类型参数解析为其上限。
实施复制自改造。RestMethodInfo。
