Wiremock 存根错误：“无法识别的字段 \"timestamp\"（com.github.tomakehurst.wiremock.common.Errors 类），未标记为可忽略”

Question

我来这里是因为我还没有找到解决问题的方法。我实际上是在尝试使用wiremock 来存根响应（对Mocked 服务的调用是通过FeignClient 完成的）。我的意图是在真实的应用程序中而不是在测试中，而不是在真实的应用程序中获得真实的伪装客户端的虚假响应。因此，在这种情况下，我不是在测试中存根 WireMockServer，而是在 Spring Boot 应用程序类中存根，但是当在那里存根响应时，我遇到了一个非常奇怪的错误，到目前为止我已经调查了很多但没有成功。

这是我目前使用的代码：

@EnableFeignClients
@SpringBootApplication
public class CrmApplication
      implements CommandLineRunner
{
    private final ConfigurableApplicationContext context;private final ConfigurableApplicationContext context;

    @Autowired
    public CrmApplication( ConfigurableApplicationContext context )
    {
        this.context = context;
    }

    public static void main( String[] args )
    {
        log.info( "Starting the CRM Validator" );
        SpringApplication.run( CrmApplication.class, args );
        log.info( "Finishing the CRM Validator" );
    }

    @Override
    public void run( String... args )
    {
        final WireMockServer server = new WireMockServer( options().port( 8000 ) );
        server.start();
        log.info( "Wiremock has started in the following url: {}", "http://localhost:8000\n\n" );

        String resultJson = "{\"id\":1,\"hasJudicialRecords\":false}";

        MappingBuilder mappingBuilder = get( urlPathEqualTo( "/api/v1/judicial-registry/1") )
              .willReturn( aResponse().withStatus( 200 )
                                      .withHeader( "Content-Type", "application/json" )
                                      .withBody( resultJson ) )
        stubFor( mappingBuilder );

    }
}

这实际上在stubFor( mappingBuilder ); 行中失败了，这是我得到的例外：

所以一个问题是，wiremock 是否只在测试中起作用？

我已尝试更改 JSON 及其字段，但这似乎不起作用，所以如果你们中的任何人知道如何解决该问题会有所帮助，或者如果您也知道如何存根被调用的 api 请求@FeignClient（不是在测试中，而是在真正的 Spring 应用程序运行中）作为替代方案可能也可以工作。

谢谢！

Answer 1

server.start() 之后你需要：

configureFor("localhost", server.port());
