Spring 4 Create Bean Programmatically -

-

i've been looking way add datasources @ runtime. want move away defining datasources in @configuration class , instead when app loads want dynamically create datasource beans , inject them spring context. i'm not sure how can go doing that.

this ended with, not sure if right approach or not, if there better way please share.

    @component class springcontextlistener implements applicationlistener<contextrefreshedevent> {      public void onapplicationevent(contextrefreshedevent event) {         org.apache.tomcat.jdbc.pool.datasource ds = new org.apache.tomcat.jdbc.pool.datasource();         ds.setdriverclassname("com.mysql.jdbc.driver");         ds.seturl("jdbc:mysql://mysql:3306/test?useunicode=true&characterencoding=utf8&maxallowedpacket=512000");         ds.setusername("myusername");         ds.setpassword("mypassword");         configurableapplicationcontext ctx = (configurableapplicationcontext) event.getapplicationcontext();         configurablelistablebeanfactory bf = ctx.getbeanfactory();         bf.registersingleton("mysqldsn", ds);     }; }

this example of want do, have ability dynamically create beans , add them them spring rather writing out config files.

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...
