@Scheduled running at 16:00

I've created this method in SpringBoot

    @Scheduled(cron = "0 16 * * * *")
    public void sendMsg() {
}

to be executed At 16:00 pm (noon) every day:

but instead is executed several times per day

As was pointed by previous answers your expression is not valid "Spring expression", but rather unix expression. Spring utilizes Quartz-type which adds a value of seconds as a very first parameter:

+-------------------- second (0 - 59)
|  +----------------- minute (0 - 59)
|  |  +-------------- hour (0 - 23)
|  |  |  +----------- day of month (1 - 31)
|  |  |  |  +-------- month (1 - 12)
|  |  |  |  |  +----- day of week (0 - 6) (Sunday=0 or 7)
|  |  |  |  |  |  +-- year [optional]
|  |  |  |  |  |  |
*  *  *  *  *  *  * command to be executed

It should look like this:

@Scheduled(cron = "0 0 16 * * *")
    public void sendMsg() {
}

I think your expression should be 0 0 16 ? * * *

There are many online cron evaluator you can use for both evaluating an expression or creating one.
