java - Is there a way to run a method/class only on Tomcat/Wildfly/Glassfish startup? -

-

i need remove temp files on tomcat startup, pass folder contains temp files in applicationcontext.xml.

is there way run method/class on tomcat startup?

you write servletcontextlistener calls method contextinitialized() method. attach listener webapp in web.xml, e.g.

<listener>    <listener-class>my.listener</listener-class> </listener>

and

package my;  public class listener implements javax.servlet.servletcontextlistener {     public void contextinitialized(servletcontext context) {       myotherclass.callme();    } }

strictly speaking, run once on webapp startup, rather tomcat startup, may amount same thing.

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
