Understanding Spring Web Initialization

Few years ago majority of us were used to write XML config files everywhere, to setup even simple Java EE application. Today using Java or Groovy to configure projects is becoming preferred way - you just need to take a look at Gradle or functionalities introduced in further versions of the Spring Framework to gen up on this. Now I'll deal with configuring Spring contexts for web application. Java EE provides ServletContainerInitializer interface, which allows libraries to be notified of a web application startup. Since Spring 3.1 we have SpringServletContainerInitializer class which handles WebApplicationInitializer by instantiating all found classes implementing this interface, sorting them basing on @Order annotation (non-annotated classes gets the highest possible order, so they are processed at the end) and invoking onStartup() method.

Using jstat to report custom JVM metric sets

I've always been missing possibility to configure custom headers in JStat . Of course there are a lot of predefined data sets, but it'll be nicer if we could create our own data set. And as you probably already devised I'm writing this post because such functionality is of course available :) Unfortunately I haven't found it in any documentation so now I'll try to fill this gap. First thing we have to do is to provide custom descriptor with possible JStat options. This descriptor is just a text file containing something we'll call "jstat specification language". To make this custom file available to JStat we should place it in the following path: $HOME/.jvmstat/jstat_options If you want to view the bundled options please refer to  file in OpenJDK repository . The specification language is pretty similar to json files, and it contains the group of option  elements. Each option should be threaten as a set of columns that can be shown in single jsta

Spring integration testing with Spock

I'm currently working on a project where we use Spring Framework 4.0 and Spock for testing. Unit testing in Spock is really great, but there are some lacks in integration testing - especially in mocking Spring beans. Our requirement is to start up Spring context but with particular bean replaced with mock. The easiest part we had do implement is just regular Spring test specification: @ContextConfiguration( classes = [GatewayConfig, PaymentServiceConfig]) class PaymentServiceSpecIT extends Specification { final String CLIENT_ID = "54321" @Inject PaymentService paymentService def "Should return auth token"() { when: def token = paymentService.getAuthToken(CLIENT_ID) then: token } }
