Example 1 with CircuitBreakerFailoverFeature

use of org.apache.cxf.clustering.circuitbreaker.CircuitBreakerFailoverFeature in project cxf by apache.

the class CircuitBreakerFailoverTest method testSequentialStrategyWithElapsingCircuitBreakerTimeout.

@Test
public void testSequentialStrategyWithElapsingCircuitBreakerTimeout() throws Throwable {
    FailoverFeature feature = customizeFeature(new CircuitBreakerFailoverFeature(1, 3000), false, "http://localhost:" + NON_PORT + "/non-existent", "http://localhost:" + NON_PORT + "/non-existent2");
    final BookStore bookStore = getBookStore("http://localhost:" + NON_PORT + "/non-existent", feature);
    // should reset all circuit breakers and the URLs could be tried again.
    for (int i = 0; i < 2; ++i) {
        try {
            bookStore.getBook(1);
            fail("Exception expected");
        } catch (ProcessingException ex) {
            if (!(ex.getCause() instanceof IOException)) {
                throw ex.getCause();
            }
        }
        // Let's wait a bit more than circuit breaker timeout
        Thread.sleep(4000);
    }

Example 2 with CircuitBreakerFailoverFeature

use of org.apache.cxf.clustering.circuitbreaker.CircuitBreakerFailoverFeature in project testcases by coheigea.

the class FailoverTest method testCircuitBreaker.

@org.junit.Test
public void testCircuitBreaker() throws Exception {
    URL busFile = FailoverTest.class.getResource("cxf-client.xml");
    CircuitBreakerFailoverFeature feature = new CircuitBreakerFailoverFeature();

    Number numberToDouble = new Number();
    numberToDouble.setDescription("This is the number to double");

    Response response = client.post(numberToDouble);
    assertEquals(response.getStatus(), 200);
