java.lang.IllegalArgumentException：json string不能为null或为空

时间：2018-01-24 08:34:05

标签： java spring rest-assured spring-cloud-contract

我使用独立设置模拟了我的其他控制器，我得到了以下异常。我正在使用线程调用我的控制器调用的外部服务。 spring cloud contract使用下面的类，它会自动生成MockMvcRequestSpecification和ResponseOptions测试场景

这是我的代码。 

@RunWith(SpringRunner.class)
@TestPropertySource("classpath:application.yml")
@SpringBootTest(classes = Application.class)
public abstract class AccountsControllerContractTest {

@Value("${groups}")
private String groups;

@Value("${service1}")
private String service1;

@Value("${service2}")
private String service2;

private ServiceProvider1 serviceProvider1;

private ServiceProvider2 ServiceProvider2;


@Autowired
WebClient webClient;

    WebClient webClient1 = WebClient.builder().clientConnector(new ReactorClientHttpConnector(new Consumer<HttpClientOptions.Builder>() {
        @Override
        public void accept(HttpClientOptions.Builder builder) {
            builder.compression(true);
        }
    })).build();

    WebClient webClient2 = WebClient.builder().clientConnector(new ReactorClientHttpConnector(new Consumer<HttpClientOptions.Builder>() {
        @Override
        public void accept(HttpClientOptions.Builder builder) {
            builder.compression(true);
                       }
    })).build();


    serviceProvider1 = new ServiceProvider1(webClient1, service1, 20);
    serviceProvider2 = new ServiceProvider2(webClient2, service2, tam, 20);

    RestAssuredMockMvc.standaloneSetup(MockMvcBuilders.standaloneSetup(new AccountsController(new EntitlementsService(serviceProvider1, ServiceProvider2))));

   }
 }

执行构建时，它会自动生成测试用例，控制器调用wiremocks（我可以在日志中看到响应）。但是控制器没有收到回复。

任何帮助？

答案 0 :(得分：1)

将@Autowired WebApplicationContext context传递给RestAssuredMockMvc. webAppContextSetup(context)。由于您已经开始使用整个上下文，因此使用独立案例是没有意义的。很可能你错过了一个文件管理器，或者如果你通过整个上下文它应该更好。
