你使用了哪个项目？
hippo4j config
你使用了哪个版本？
1.5.0-SNAPSHOT
预期行为
内存中Web Executor 成功更新至最新参数
实际行为
空指针
原因分析（如果可以）
cn.hippo4j.adapter.web.AbstractWebThreadPoolService类实现了ApplicationRunner, 用于在启动后(run方法)从上下文当中获取嵌入式Web容器, 再获取其中的线程池. 但是由于没有指定优先级, 比cn.hippo4j.config.springboot.starter.refresher.AbstractConfigThreadPoolDynamicRefresh执行的晚, 导致在启动时收到配置变更信息时,cn.hippo4j.adapter.web.AbstractWebThreadPoolService当中的web容器线程池为空, 报空指针异常, 刷新失败.问题重现步骤

使用@order注解, 指定获取Web容器线程池的
AbstractWebThreadPoolService为最先执行的ApplicationRunnerThe text was updated successfully, but these errors were encountered:
