java.lang.NoClassDefFoundError : io/netty/util/concurrent/RejectedExecutionHandlers

Question

我正在使用 pack jvm Consumer 编写测试，并且在运行测试时收到以下错误:-

代码:-

@Test
public void createUser() throws Exception {
    Map<String, String> responseHeaders = new HashMap<>();
    responseHeaders.put("Content-Type", "application/json;charset=UTF-8");
    PactFragment fragment = buildPublisherRequest(responseHeaders);

    MockProviderConfig config = MockProviderConfig.createDefault();


    MappingJackson2HttpMessageConverter converter = getMappingConverter();

    RestTemplate template = new RestTemplate(Collections.<HttpMessageConverter<?>> singletonList(converter));
    VerificationResult result = fragment.runConsumer(config, config1 -> {
        ConfigApplication ds = new ConfigApplication();
        RestApiServiceImpl rs = new RestApiServiceImpl();


        ReflectionTestUtils.setField(ds, "host", config.url());

        ReflectionTestUtils.setField(ds, "restApiService", template);


    });
    if (result instanceof PactError) {
        throw new RuntimeException(((PactError)result).error());
    }
    assertEquals(ConsumerPactTest.PACT_VERIFIED, result);
}

上面代码中fragment.runConsumer(...)这行发生了错误。

错误:-

现有依赖项:-

<dependency>
    <groupId>au.com.dius</groupId>
    <artifactId>pact-jvm-consumer-junit_2.11</artifactId>
    <version>3.3.3</version>
    <scope>test</scope>
</dependency>

我是否需要添加任何其他依赖项？

如何解决这个问题？

Answer 1

netty版本有问题。

不同版本的 spring-cloud-starter-eureka 和 pact-jvm-consumer_2.11 依赖中均使用了 netty。我已在 pact-jvm-consumer_2.11 中排除了 netty-handler，并且错误现已解决。
