nacos-cloud 应用接入
nacos-cloud 应用接入dynamictp大约 5 分钟
提示
动态线程池配置文件,建议单独开一个文件放到 nacos 中,如:user-center-dtp-dev.yml
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
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
注意 spring-cloud-alibaba 场景下使用 nacos 用此依赖,非 cloud 场景用前一个依赖
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
- 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
