Spring annotation @Scheduled (cron = "0 0 1 * * *") is used to implement timed tasks

Recently, the internship wrote a small timing statistics program, with spring @Scheduled annotations, the note relies on the following jar package

<span style= "FONT-SIZE:14PX;" > <dependency>
            <groupId>org.springframework</groupId>
            <artifactId> spring-context</artifactid>
            <version>3.1.1.RELEASE</version>
        </dependency>< /SPAN>

Before using this annotation, please do the following to prepare and configure the appropriate XM file.

The meanings of each parameter in the cron parameter are given below:
