我正在使用pack jvm consumer编写测试，并且在运行测试时遇到以下错误： -
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);
}
上述代码中此行fragment.runConsumer（...）出错。
错误： -

现有依赖关系： -
<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？
如何解决此问题？
答案 0 :(得分：0)
netty版本存在问题。
netty用于spring-cloud-starter-eureka和pact-jvm-consumer_2.11依赖于不同版本。我已经在pact-jvm-consumer_2.11中排除了netty-handler，现在错误得到了解决。
