polaris-cloud 应用接入

yanhompolaris-cloud 应用接入dynamictp大约 4 分钟

提示

  1. 动态线程池配置文件,建议单独开一个文件放到 polaris 中,如:user-center-dtp-dev.yml

  2. 如果配置中心支持 yml 格式,建议最好使用 yml 文件配置,可读性、可操作性更友好

  3. 给出的是全配置项,使用不到的项或者使用默认值的项都可以删除,减少配置量

  4. 集成失败 90% 以上情况都是使用姿势有误 / 版本兼容问题,有版本兼容性问题可以提 Issues 或加群反馈

警告

  1. 下述配置项的值都是随便填写的,请不要直接使用该值,根据自己项目做调整
