java - Spring Bean Creation at Runtime -


i'm trying create beans @ runtime using @configuration , @bean annotations. reason trying have spring aware of created beans can handle scheduling application creating. i've defined annotated class so:

@configuration   public class gathererconfigbean {     @bean(name = "factorybean")     public methodinvokingjobdetailfactorybean createmethodinvokingjobdetail(string service, object obj, string method) throws classnotfoundexception, nosuchmethodexception{         methodinvokingjobdetailfactorybean jobdetailfactory = new methodinvokingjobdetailfactorybean();         jobdetailfactory.setbeanname(service + "factorybean");         jobdetailfactory.settargetobject(obj);         jobdetailfactory.settargetmethod(method);         jobdetailfactory.setconcurrent(false);         jobdetailfactory.afterpropertiesset();         return jobdetailfactory;     }      @bean(name = "triggerbean")     public crontriggerbean createtriggerbean(string service, jobdetail job, string schedule) throws parseexception{         crontriggerbean trigger = new crontriggerbean();         trigger.setbeanname(service + "triggerbean");         trigger.setjobdetail(job);         trigger.setcronexpression(schedule);         return trigger;     }      public crontrigger createtrigger(string service, jobdetail job, string schedule) throws parseexception{         return createtriggerbean(service, job, schedule);     }      public jobdetail createjobdetail(string service, abstractgatherer obj, string method) throws classnotfoundexception, nosuchmethodexception{         return (jobdetail) createmethodinvokingjobdetail(service, obj, method).getobject();     } }

the problem when run following exceptions , have been unable find similar example of doing on-line. originally, had thought because have same name, doesn't seem case because when run 1 same error.

any help, feedback, ideas, or suggestions appreciated, , let me know if need more specific information!

i suggest use @postconstruct annotation on 1 of method needs executed after dependency injection performed. have @ link know more it.

one more way make class implement applicationcontextaware interface access application context. more details on please refer link.

hope helps you. cheers.
