Question

我有以下方法声明：

@Scheduled(cron = "0 0 12 ? * MON#1")
protected synchronized void execute() {...}

但是我的应用程序启动失败，并且我在日志中看到以下错误：

Caused by: java.lang.IllegalStateException: Encountered invalid @Scheduled method 'execute': For input string: "1#1"

如何更正？

Answer 1

当Spring Boot无法识别cron表达式时，将发生错误。应该可能是由于MON#1部分。

This可能有助于在Spring启动中找到正确的cron表达式。

java.lang.IllegalStateException：遇到无效的@Scheduled方法“ execute”：对于输入字符串：“ 1＃1”
