春天云合同MockHttpServlet抛出非法参数异常。

Question

我正在使用spring cloud contract为使用eureka和ribbon的微服务编写测试。我能够生成存根，并且成功部署，但当我尝试向消费者服务发送请求时，它抛出一个IllegalArgument异常。我试着添加了头文件，但我还是得到了同样的异常。

这是我的代码

@SpringBootTest(classes = Application.class, webEnvironment = WebEnvironment.MOCK)
@AutoConfigureJsonTesters
@RunWith(SpringRunner.class)
@AutoConfigureMockMvc
@ActiveProfiles("dev")
@DirtiesContext
@AutoConfigureStubRunner(workOffline = true, ids = "com.example:example:+:stubs:8182")
@FixMethodOrder(MethodSorters.NAME_ASCENDING)

public class ExampleTest{
    static {
        System.setProperty("eureka.client.enabled", "false");
        System.setProperty("spring.cloud.config.failFast", "false");
        System.setProperty("stubrunner.cloud.ribbon.enabled", "false");
        System.setProperty("stubrunner.cloud.enabled", "false");
    }

    @Autowired MockMvc mockMvc;

    @Test
    public void testName() {
try {

        mockMvc.perform(get("/example_endpoint").header("host", "localhost:80")).andDo(print());
}
catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

这是我得到的异常
