Java – Spring Controller destroy method

jakarta-eejavaservletsspring

Does Spring's Controller have any sort of destroy/cleanup method? I couldn't find anything in the JavaDocs for Controller and AbstractController. I'm looking for the equivalent of javax.servlet.Servlet's destroy() method.

The reason for this is that I'm starting a thread in my Spring controller. I want the thread to terminate whenever the controller is taken out of server (such as when the container is shutdown).

Just use the regular spring lifecycle methods. Because all Spring Controllers are Spring beans they will follow the regular lifecycle.

Just do it the usual way and then insert it using SecurityContextHolder.setContext() in your test class, for example:

Controller:

Authentication a = SecurityContextHolder.getContext().getAuthentication();

Test:

Authentication authentication = Mockito.mock(Authentication.class);
// Mockito.whens() for your authorization object
SecurityContext securityContext = Mockito.mock(SecurityContext.class);
Mockito.when(securityContext.getAuthentication()).thenReturn(authentication);
SecurityContextHolder.setContext(securityContext);

Java – Simple way to repeat a string

Here is the shortest version (Java 1.5+ required):

repeated = new String(new char[n]).replace("\0", s);

Where n is the number of times you want to repeat the string and s is the string to repeat.

No imports or libraries needed.
