Use of the Spring2.5.6 timer

The timer was recently used in the work, and the project was using SSH, so consider using spring's timer to implement the function, but after understanding the requirements, spring's simpletriggerbean and Crontriggerbean are not satisfied. The requirements are:

1.3 timers are required to check the encrypted fields of 2 data tables at a specific time. If the sensitive data of the database is found to have been modified (not the same as the encrypted field), a warning data is generated for the modified data to be saved to the system warning table, in the background management system, The administrator can deal with it in time. The check field of the modified data is also changed to false. For maintenance personnel to query data.

2. First timer: Start daily 2 o'clock in the morning and check the data from 2 o'clock in the morning to 2 o'clock in the morning today.

3. Second timer: Every 2 days, 2:10 minutes, check the data 2 days before 2 o'clock in the morning to today 2 o'clock in the morning.

4. Third timer: Every 3 days, 2:20 minutes, check the data 3 days before 2 o'clock in the morning to today 2 o'clock in the morning.

5. It is necessary to ensure that each record is checked 3 times during the 3 timer cycle. When examining data, avoid creating too many objects in the database lock table and code, querying only the first 100 records at a time, verifying 100 data after checking the last ID and avoiding duplicate checking.

When using Crontriggerbean to do, you can use the expression of cronexpression to configure every few days in a few seconds a few milliseconds to run, but later found that the cronexpression expression ' days ' parameters, from the monthly number 1th is calculated, Instead of counting from the day the server started, the 3rd timer will be executed less once a month is only 30 days or 29 days.

With simpletriggerbean words, in the online search configuration, the entire big talk is Ctrl+c,ctrl+v said Startdelay and Repeatinterval configuration and use. Because the server startup time is uncertain, Therefore, the delay time for the first execution cannot be configured here.

2 kinds of triggers are not, all can only meet part of the demand, so went to see the spring time task of the source code. And then I have a train of thought, Simpletriggerbean can configure the cycle of each timer loop execution, So as long as the 3 timer to determine the first execution time can be configured on the line, so that a custom class, inherit Simpletriggerbean, define the parameters of the configuration, and then rewrite the Setstarttime method, the problem can be resolved. Here's the code:

The Customsimpletriggerbean class is a class that defines its own inheritance Simpletriggerbean. Checktimevalue is the point of judgment, such as when the server startup time exceeds the setting for this time, Then the time for the first run of the scheduled task starts tomorrow. Delayexpression expression has 5 parameters separated by a space, respectively, the time of day and minute milliseconds, representing the timing of the first run of the task, the parameter ' days ' is the server started the day after the delay of a few days, The next 4 parameters are the specific set time, 5 parameters can be any one, each parameter has a default value, the following paste Customsimpletriggerbean code:
