如何使用mockMvc测试gzip？

Question

我正在测试 Spring Boot 压缩属性：

server.compression.enabled=true

我想验证在发送带有 header 的请求后"Accept-Encoding":"gzip"，
我会收到带有 header 的响应"Content-Encoding":"gzip"。

该测试适用于 TestRestTemplate，但不适用于 MockMvc。

我创建了一个新项目并添加了上述属性以及此控制器：

@RestController
public class IssueController {

    @GetMapping
    public Person getString() {
        return new Person("ADSDSADSDSA", "REWREWREWREW");
    }

    class Person {
        private String name;
        private String surname;

        //Constructor, getters and setters
    }
}

使用 TestRestTemplate 进行工作测试

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class TestIssueControllerIntegrationTest {

    @Autowired
    private TestRestTemplate testRestTemplate;

    @Test
    public void testGzip(){
        HttpHeaders httpHeaders= new HttpHeaders();
        httpHeaders.add("Accept-Encoding", "gzip");

        HttpEntity<Void> requestEntity = new HttpEntity<>(httpHeaders);

        ResponseEntity<byte[]> response = testRestTemplate.exchange("/", HttpMethod.GET, requestEntity, byte[].class);

        assertThat(response.getHeaders().get("Content-Encoding").get(0), equalTo("gzip"));
    }
}

测试不适用于 MockMvc

@WebMvcTest(IssueController.class)
public class TestIssueController {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testGzip() throws Exception {
        MvcResult result = this.mockMvc.perform(MockMvcRequestBuilders.get("/").header("Accept-Encoding", "gzip")).andReturn();

        assertThat(result.getResponse().getHeader("Content-Encoding"), CoreMatchers.equalTo("gzip"));
    }
}

真的不可能用mockMvc测试压缩还是我做错了什么？
