如何读取@Schedule注释中的整数值?
@Schedule 中使用的变量是在其他项目中定义的,但要在另一个项目中使用它 它在类中读取并在其他文件中传入@Scheduled。
该变量在类中定义为:
@Value("${cron_frequency_interval_for_logs}")
int cronFrequencyIntervalForLogs;
并用作
@Scheduled(fixedDelayString = "${cron_frequency_interval_for_logs}")
这工作正常,但所需的时间以毫秒为单位,并且在 String 类型中也是如此。
我想要并尝试的是:想要整数形式的时间并以分钟为单位:
@Value("${cron_frequency_interval_for_logs}")
int cronFrequencyIntervalForLogs;
这个语法是我从互联网复制的,但对我不起作用。
@Scheduled(fixedDelay = "#{new Integer('${cron_frequency_interval_for_logs}')}")
我希望时间以分钟为第一优先级,但通过参考下面的文章,我知道格式将是 5*60*1000 5 分钟,在这种情况下,如果我可以在变量中存储 5 并且可以进行其余的计算,因为这将是重复的。
有什么办法可以做到这一点吗? 提到了这个
The variable used in @Schedule is defined in some other project but to use it in another project
it is read in a class and the passed in @Scheduled in other file.
The variable is defined in the class as:
@Value("${cron_frequency_interval_for_logs}")
int cronFrequencyIntervalForLogs;
and used as
@Scheduled(fixedDelayString = "${cron_frequency_interval_for_logs}")
This works fine but the time it takes is in milliseconds and that too in String type.
What I want and tried is: want the time in integer form and in minutes:
@Value("${cron_frequency_interval_for_logs}")
int cronFrequencyIntervalForLogs;
This syntax I copied from internet but didn't work for me.
@Scheduled(fixedDelay = "#{new Integer('${cron_frequency_interval_for_logs}')}")
I want the time to be in minutes as first priority but by referring to the below article I got to know the format would be 5*60*1000 for 5 minutes and in such a case if I can just store 5 in the variable and can do the rest of the calculation as that is going to be repetitive.
Is there any way of doing this?

假设您有一个名为
run-Frequency.mines
的属性(不是变量),其中包含一个整数,表示您希望执行某个方法的频率。有三个注释属性会派上用场:initialDelayString
- 第一次执行之前等待时间的值。fixedDelayString
- 执行之间等待时间的值。timeUnit
- 评估上述两个值(分钟、秒等)时使用的单位。附带说明一下,这里是该注释的 JavaDoc:https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/annotation/Scheduled.html
Let's say you have a property (not a variable) called
run-frequency.minutes
which contains an integer of how frequently you would like a method to execute. There are three annotation properties that will come in handy:initialDelayString
- Value of how long to wait before the first execution.fixedDelayString
- Value of how long to wait between executions.timeUnit
- The unit to use when evaluating the above two values (MINUTES, SECONDS, etc).On a side note, here is the JavaDoc for that annotation: https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/annotation/Scheduled.html
