/**

* Feign 客户端专用的 Jackson 配置：使用默认驼峰命名策略。
|
* <p>
|
* jnpf-extend 全局 {@link JacksonConfig} 把 ObjectMapper 配成 SNAKE_CASE
|
* （前端约定的蛇形契约），但其他 jnpf-* 微服务对外 REST 接口仍用驼峰。
|
* 全局蛇形 mapper 会被 Spring Cloud OpenFeign 默认 Decoder 复用，
|
* 导致 Feign 调 jnpf-permission 等服务时 JSON 字段名映射不上 → entity 字段全 null。
|
* <p>
|
* 这里给 Feign 单独装一个驼形 ObjectMapper 的 Decoder/Encoder，
|
* 不影响 MVC 自身对前端的蛇形响应。
