 > 面包屑的配置方式有三种，一是直接配置 `breadcrumbList`，二是结合 `react-router@2` `react-router@3`，配置 `routes` 及 `params` 实现，类似 [面包屑 Demo](https://ant.design/components/breadcrumb-cn/#components-breadcrumb-demo-router)，三是结合 `react-router@4`，配置 `location` `breadcrumbNameMap`，优先级依次递减，脚手架中使用最后一种。 对于后两种用法，你也可以将 `routes` `params` 及 `location` `breadcrumbNameMap` 放到 context 中，组件会自动获取。
