Examples with Target feign.Target used on opensource projects

Example 1 with Target

use of feign.Target in project feign-reactive by kptfh.

the class HystrixReactiveHttpClientTest method getSetterFactory.

static CloudReactiveFeign.SetterFactory getSetterFactory(int testNo) {
    return new CloudReactiveFeign.SetterFactory() {

        @Override
        public HystrixObservableCommand.Setter create(Target<?> target, MethodMetadata methodMetadata) {
            String groupKey = target.name();
            String commandKey = methodMetadata.configKey();
            return HystrixObservableCommand.Setter.withGroupKey(HystrixCommandGroupKey.Factory.asKey(groupKey)).andCommandKey(HystrixCommandKey.Factory.asKey(commandKey + testNo)).andCommandPropertiesDefaults(HystrixCommandProperties.Setter().withCircuitBreakerRequestVolumeThreshold(1));
        }
    };
}

Example 2 with Target

use of feign.Target in project feign by OpenFeign.

the class Http2ClientAsyncTest method decodingExceptionGetWrappedInDecode404Mode.

@Test
public void decodingExceptionGetWrappedInDecode404Mode() throws Throwable {
    server.enqueue(new MockResponse().setResponseCode(404));
    thrown.expect(DecodeException.class);
    thrown.expectCause(isA(NoSuchElementException.class));
    final TestInterfaceAsync api = newAsyncBuilder().decode404().decoder((response, type) -> {
        assertEquals(404, response.status());
        throw new NoSuchElementException();
    }).target("http://localhost:" + server.getPort());
    unwrap(api.post());
}

Example 3 with Target

use of feign.Target in project feign by OpenFeign.

the class Http2ClientAsyncTest method throwsFeignExceptionWithoutBody.

@Test
public void throwsFeignExceptionWithoutBody() {
    server.enqueue(new MockResponse().setBody("success!"));
    final TestInterfaceAsync api = newAsyncBuilder().decoder((response, type) -> {
        throw new IOException("timeout");
    }).target("http://localhost:" + server.getPort());
    try {
        api.noContent();
    } catch (final FeignException e) {
        Assertions.assertThat(e.getMessage()).isEqualTo("timeout reading POST http://localhost:" + server.getPort() + "/");
        Assertions.assertThat(e.contentUTF8()).isEqualTo("");
    }
}

Example 4 with Target

use of feign.Target in project feign-reactive by kptfh.

the class HystrixReactiveHttpClientTest method getSetterFactory.

CloudReactiveFeign.SetterFactory getSetterFactory(int testNo) {
    return new CloudReactiveFeign.SetterFactory() {

        @Override
        public HystrixObservableCommand.Setter create(Target<?> target, MethodMetadata methodMetadata) {
            String groupKey = target.name();
            HystrixCommandKey commandKey = HystrixCommandKey.Factory.asKey(methodMetadata.configKey() + testNo);
            lastCommandKey.set(commandKey);
            return HystrixObservableCommand.Setter.withGroupKey(HystrixCommandGroupKey.Factory.asKey(groupKey)).andCommandKey(commandKey).andCommandPropertiesDefaults(HystrixCommandProperties.Setter().withCircuitBreakerRequestVolumeThreshold(VOLUME_THRESHOLD).withExecutionTimeoutEnabled(false).withCircuitBreakerSleepWindowInMilliseconds(SLEEP_WINDOW).withMetricsHealthSnapshotIntervalInMilliseconds(10));
        }
    };
}

Example 5 with Target

use of feign.Target in project feign-reactive by kptfh.

the class HystrixReactiveHttpClientTest method shouldOpenCircuitBreaker.

@Test
public void shouldOpenCircuitBreaker() throws IOException, InterruptedException {
    String body = "success!";
    int callsNo = 10;
    LoadBalancingReactiveHttpClientTest.mockSuccessAfterSeveralAttempts(server, "/", callsNo, SC_SERVICE_UNAVAILABLE, aResponse().withStatus(200).withHeader("Content-Type", "application/json").withBody(body));
    LoadBalancingReactiveHttpClientTest.TestInterface client = CloudReactiveFeign.<LoadBalancingReactiveHttpClientTest.TestInterface>builder().webClient(WebClient.create()).setHystrixCommandSetterFactory(getSetterFactory(testNo)).target(LoadBalancingReactiveHttpClientTest.TestInterface.class, "http://localhost:" + server.port());
    List<Object> results = IntStream.range(0, callsNo).mapToObj(i -> {
        try {
            return client.get().block();
        } catch (Throwable t) {
            return t;
        }
    }).collect(Collectors.toList());
    assertThat(server.getAllServeEvents().size()).isLessThan(callsNo);
    Throwable firstError = (Throwable) results.get(0);
    assertThat(firstError).isInstanceOf(HystrixRuntimeException.class);
    assertThat(firstError.getMessage()).contains("failed and no fallback available");
    Throwable lastError = (Throwable) results.get(results.size() - 1);
