Add this to your Wicket application class to limit Wicket dev mode warning to one per JVM instead of per test. Reduces clutter in build log.

	private static boolean warnedAboutDevMode = false;

	@Override
	protected void outputDevelopmentModeWarning() {
	if (warnedAboutDevMode) {
	return;
	}
	super.outputDevelopmentModeWarning();
	warnedAboutDevMode = true;
	}

runeflobakk / EqualsAndHashCodeTemplate.java

Created August 23, 2011 10:57

equals() and hashCode() template for Eclipse. It uses EqualsBuilder and HashCodeBuilder in Apache Commons Lang.

	${e:import(org.apache.commons.lang3.builder.EqualsBuilder)}
	${h:import(org.apache.commons.lang3.builder.HashCodeBuilder)}


	@Override
	public boolean equals(Object object) {
	if (object instanceof ${enclosing_type}) {
	${enclosing_type} another = (${enclosing_type}) object;
	return new EqualsBuilder().append(${replaceWithFieldName}, another.${replaceWithFieldName}).isEquals();
	}

	private Person per = new Person("Per", new Address("A-gate 5", "0560", "Oslo"), 30);
	private Person kari = new Person("Kari", new Address("B-gate 4", "0560", "Oslo"), 37);

	@Test
	public void knowsWhichRelativesLivingInTheSamePostalCode() {
	per.relateTo(SIBLING, kari);

	Collection<Relative> nearbyRelatives = per.getRelativesWithSamePostalCode();
	assertThat(nearbyRelatives, hasSize(1));

Created October 18, 2011 20:03

	public class SecurityLevelVoter implements AccessDecisionVoter {

	private String securityLevelPrefix = "SECURITY_LEVEL_";

	public int vote(Authentication authentication,
	Object object,
	Collection<ConfigAttribute> attributes) {

	int result = ACCESS_ABSTAIN;
	Object principal = authentication.getPrincipal();

runeflobakk / SupportedBy.java

Created October 18, 2011 22:06

Funksjon som sjekker om ConfigAttributes støttes av en AccessDecisionVoter.

	public class SupportedBy implements Predicate<ConfigAttribute> {

	private final AccessDecisionVoter voter;

	public SupportedBy(AccessDecisionVoter voter) {
	this.voter = voter;
	}

	public boolean evaluate(ConfigAttribute attribute) {
	return voter.supports(attribute);

Created October 18, 2011 22:14

Snippet: Dersom det ikke finnes ConfigAttributes som støttes av SecurityLevelVoter, returner ACCESS_ABSTAIN

	Collection<ConfigAttribute> supportedAttributes = select(attributes, new SupportedBy(this));
	if (supportedAttributes.isEmpty()) {
	return ACCESS_ABSTAIN;
	}

runeflobakk / AcceptingSecurityLevelOf.java

Created October 30, 2011 20:24

Funksjon for å avgjøre om MyPrincipal sitt sikkerhetsnivå er høyt nok for det som kreves av ConfigAttributes

	public class SecurityLevelVoter implements AccessDecisionVoter {

	private String securityLevelPrefix = "SECURITY_LEVEL_";
	//...snip...
	private class AcceptingSecurityLevelOf implements Predicate<ConfigAttribute> {

	private final int principalSecurityLevel;

	public AcceptingSecurityLevelOf(MyPrincipal principal) {
	principalSecurityLevel = toInt(principal.getSecurityLevel(), Integer.MIN_VALUE);

Created October 30, 2011 20:36

Vi har en eller flere støttede ConfigAttributes, og sjekker om det finnes en som aksepterer sikkerhetsnivået til principalen.

	Object p = authentication.getPrincipal();
	if (p instanceof MyPrincipal
	&& exists(supportedAttributes, new AcceptingSecurityLevelOf((MyPrincipal) p))) {
	return ACCESS_GRANTED;
	} else {
	return ACCESS_DENIED;
	}

runeflobakk / SecurityLevelVoter#vote.java

Created October 30, 2011 20:48

Hele vote-metoden hvor implementasjonen reflekterer bedre slik vi ville forklart forrutsetningene for brukertilgang.

	public int vote(Authentication authentication,
	Object object,
	Collection<ConfigAttribute> attributes) {

	Collection<ConfigAttribute> supportedAttributes =
	select(attributes, new SupportedBy(this));
	if (supportedAttributes.isEmpty()) {
	return ACCESS_ABSTAIN;
	}

runeflobakk / gist:1326485

Created October 30, 2011 21:44

Snippet: Dersom det ikke finnes ConfigAttributes som støttes av SecurityLevelVoter, returner ACCESS_ABSTAIN. Java 8 Project Lambda-syntaks.

	Collection<ConfigAttribute> supportedAttributes =
	select(attributes, attr -> this.supports(attr));
	if (supportedAttributes.isEmpty()) {
	return ACCESS_ABSTAIN;
	}
