JBPM Notify Custom

One, as shown:

Second, the implementation of the class

public class Activitybehaviourimpl implements externalactivitybehaviour{

    private static final long Serialversionuid = 1L;

    The task is executed immediately, leaving the default
    @Override public
    void execute (activityexecution execution) throws Exception {
        SYSTEM.OUT.PRINTLN ("Send a Notice");
        The default connection
        //execution.takedefaulttransition ();
        Use the specified line name
        //execution.take (transitionname);

        Do not leave, but wait on this activity until the external call to the Signal method
        execution.waitforsignal ();
    }

    This activity is stopped by invoking the code executed before Signalexecution () is left active
    //If Execute does not stop, do not execute this method
    @Override public
    void Signal ( Activityexecution execution, String signalname, map<string,?> parameters) throws Exception {
        SYSTEM.OUT.PRINTLN ("Signal---------");
    }

Third, the use of:

public class Processdecisition {private static processengine Processengine = CONFIGURATION.G

    Etprocessengine (); @Test public void Testprocess () throws Exception {//deploy String Deployid = Processengine.getrepositorys Ervice (). Createdeployment (). Addresourcefromclasspath ("Custom/custom.jpdl.xml"). ADDRESOURCEFROMC
        Lasspath ("Custom/custom.png"). deploy ();

        SYSTEM.OUT.PRINTLN ("Deployment completed: deployid==" +deployid);
        ProcessInstance pi = Processengine.getexecutionservice (). Startprocessinstancebykey ("Custom");
        System.out.println ("Start Up: processinstanceid==" +pi.getid ());

    SYSTEM.OUT.PRINTLN ("ongoing activity name = =" +pi.findactiveactivitynames ()); @Test public void Testsignal () throws Exception {//jbpm4_execution table _id field String Executionid
        = "custom.360008";

    Processengine.getexecutionservice (). Signalexecutionbyid (Executionid); }

}
