How to use

rocks.inspectit.agent.java.tracing.core.adapter.http.proxy.JettyEventListenerProxy

constructor

@BeforeMethod
public void init() {
  // can not use @InjectMocks as span store gets injected to listener place
  proxy = new JettyEventListenerProxy(null, spanStore);
}

/**
 * {@inheritDoc}
 */
@Override
public void setSpanStore(SpanStore spanStore) {
  // get original request listener
  Object originalListener = cache.invokeMethod(jettyHttpExchange.getClass(), "getEventListener", new Class<?>[] {}, jettyHttpExchange, new Object[] {}, null);
  // create proxy for this listener
  JettyEventListenerProxy listenerProxy = new JettyEventListenerProxy(originalListener, spanStore);
  Object proxyObject = runtimeLinker.createProxy(JettyEventListenerProxy.class, listenerProxy, jettyHttpExchange.getClass().getClassLoader());
  // find the interface event listener interface, it's in the super-class of the proxy
  Class<?> eventListenerClass = proxyObject.getClass().getSuperclass().getInterfaces()[0];
  // replace with our listener
  cache.invokeMethod(jettyHttpExchange.getClass(), "setEventListener", new Class<?>[] { eventListenerClass }, jettyHttpExchange, new Object[] { proxyObject }, null);
}

  @Test
  public void listenerProvided() {
    Object originalListener = new Object();
    proxy = new JettyEventListenerProxy(originalListener, spanStore);
    Object[] args = proxy.getProxyConstructorArguments();
    assertThat(args, is(new Object[] { originalListener, Boolean.TRUE }));
  }
