How Salesforce synchronizes the card data to the central control system

first, attendance interface

Second, analysis

1) Synchronize the data first to get the data, how to get the data it.
First step: Create a trigger for the card data
The second step: Create the synchronization log class, all the card information is added to the synchronization log

2) delivery in JSON format after data is obtained from the data source
3) Create a SPRINGMVC maven project,
A, to Alibaba's Druid configuration data source,
B. Create a timer that reads information from the Salesforce log every minute
C. Write data synchronization code in the DAO layer
D, test Three, synchronization diagram:

Iv. Trigger code:

    Trigger Attendancesynctrigger on Attendance__c (after insert) {//query type list<recordtype> rtList = [S]
    Elect Id, Name, Developername, sobjecttype from RecordType WHERE sobjecttype= ' Attendance__c '];
    map<string,string> Recordmap = new map<string,string> ();      
    for (RecordType r:rtlist) {recordmap.put (r.name,r.id);
    } attendance__c order = trigger.new[0]; If it is an insert state, determine if the "Time attendance" if (Trigger.isinsert && recordmap.get (' Time Management '). Equals (order.
            Recordtypeid) {if (order! = null) {String Projson = json.serialize (order);
            System.debug (' JJJJJJJ: ' +projson);
            Create log Synlog__c syn = new Synlog__c (); Syn. Name=string.valueof (order.
            Id). subString (0,15);
            Assigning data to the log parameter Syn.parameter__c = Projson; Syn.
            Objectname__c = ' Attendance__c '; Syn.
            Operation__c = ' Insert '; Syn.      
            Flag__c = ' No ';          Insert Syn;
        } 
    } 

}
