java - Spring boot setup logging before spring application starts -

-

i have project need logging mechanism before start springapplication. how can achieve that?

i tried setup 1 logging mechanism (logmanager.getlogmanager().readconfiguration()), overridden when spring application starts.

basically want use same logging mechanism everywhere.

spring boot uses loggingapplicationlistener configure logging application. listener 1 of springapplication's default listeners. use own already-configure logging system, need configure springapplication doesn't have listener. example, remove unwanted listener, while retaining of other default listeners:

@springbootapplication public class customloggingapplication {      public static void main(string[] args) {                 springapplication application =                  new springapplication(customloggingapplication.class);          collection<applicationlistener<?>> listeners =                  new arraylist<applicationlistener<?>>();         (applicationlistener<?> listener: application.getlisteners()) {             if (!(listener instanceof loggingapplicationlistener)) {                 listeners.add(listener);             }         }         application.setlisteners(listeners);          application.run(args);     }  }

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
