The time configuration for Spring scheduled tasks is specified using a Cron expression.<\/p>\n

A Cron expression is a string that consists of 6 or 7 spaced fields representing seconds, minutes, hours, day of month, month, day of week, and year (optional). The specific syntax rules are as follows:<\/p>\n

    \n
  1. Seconds (0-59)<\/li>\n
  2. Minutes (0-59)<\/li>\n
  3. Hour (0-23)<\/li>\n
  4. Date (1-31)<\/li>\n
  5. Months (1-12 or JAN-DEC)<\/li>\n
  6. Use the numbers 1-7 to represent the days of the week, with 1 being Sunday and 7 being Saturday.<\/li>\n
  7. Year (optional)<\/li>\n<\/ol>\n

    Here are some common examples of Cron expressions:<\/p>\n

      \n
    1. “0 * * * * *”: run every minute<\/li>\n
    2. “0 0 * * * *”: Run every hour on the hour.<\/li>\n
    3. “0 0 12 * * *”\uff1aRun once every day at noon.<\/li>\n
    4. At every hour from 8 AM to 6 PM every day.<\/li>\n
    5. “Every Monday to Friday at 12:00 PM”<\/li>\n
    6. “0 0 12 ? * 6L” : It will be executed at 12 PM on the last Friday of every month.<\/li>\n<\/ol>\n

      You can specify the Cron expression for a scheduled task by using the @Scheduled annotation in the Spring configuration file, as shown below:<\/p>\n

      @Component<\/span>\r\npublic<\/span> class<\/span> MyScheduledTask<\/span> {\r\n\r\n    @Scheduled(cron = \"0 * * * * *\")<\/span>\r\n    public<\/span> void<\/span> run<\/span>()<\/span> {\r\n        \/\/ \u5b9a\u65f6\u4efb\u52a1\u7684\u903b\u8f91<\/span>\r\n    }\r\n\r\n}\r\n<\/code><\/pre>\n
      After this configuration, the scheduled task will be executed according to the specified Cron expression.<\/p>\n","protected":false},"excerpt":{"rendered":"
