本文整理了Java中feign.Feign类的一些代码示例，展示了Feign类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Feign类的具体详情如下：
包路径：feign.Feign
类名称：Feign

Feign介绍

[英]Feign's purpose is to ease development against http apis that feign restfulness.
In implementation, Feign is a Feign#newInstance for generating Target http apis.
[中]Feign的目的是简化针对假装RESTfulity的http API的开发。
在实现中，Feign是一个用于生成目标http API的新实例。
