当使用spring的webclient或webtestclient接收包含字符串列表的json主体时，我遇到了一个问题。
似乎列表没有正确解析。正文的json字符串只是放在列表的第一个条目中。
例子：

List<String> actual = this.webTestClient.get()
    .uri("/path")
    .accept(MediaType.APPLICATION_JSON)
    .exchange()
    .expectStatus().isOk()
    .expectBodyList(String.class)
    .returnResult().getResponseBody();

我在org.springframework.web.reactive.function.client.webclientintegrationtests中尝试了一个测试：

@ParameterizedWebClientTest
    void retrieveJsonArrayOfStringAsResponseEntityList(ClientHttpConnector connector) {
        this.startServer(connector);

        String content = "[\"Jane\", \"Jason\", \"John\"]";
        this.prepareResponse(response -> response.setHeader("Content-Type", "application/json").setBody(content));

        Mono<ResponseEntity<List<String>>> result = this.webClient.get()
                .uri("/json").accept(MediaType.APPLICATION_JSON)
                .retrieve()
                .toEntityList(String.class);

        StepVerifier.create(result).consumeNextWith(entity -> {
            assertThat(entity.getStatusCode()).isEqualTo(HttpStatus.OK);
            assertThat(entity.getHeaders().getContentType()).isEqualTo(MediaType.APPLICATION_JSON);
            assertThat(entity.getHeaders().getContentLength()).isEqualTo(25);
            assertThat(entity.getBody()).isEqualTo(Arrays.asList("Jane", "Jason", "John"));
        }).expectComplete().verify(Duration.ofSeconds(3));

        this.expectRequestCount(1);
        this.expectRequest(request -> {
            assertThat(request.getPath()).isEqualTo("/json");
            assertThat(request.getHeader(HttpHeaders.ACCEPT)).isEqualTo("application/json");
        });
    }

这是失败的

expected: ["Jane", "Jason", "John"]
but was : ["["Jane", "Jason", "John"]"]

以及org.springframework.test.web.reactive.server.samples.responseentitytests中的另一个失败测试：

@Test
    public void entityListString() {
        // @formatter:off
        this.client.delete()
        .exchange()
        .expectStatus().isOk()
        .expectHeader().contentType(MediaType.APPLICATION_JSON)
        .expectBodyList(String.class)
        .hasSize(3)
        .contains("Jane", "Jason", "John")
        // @formatter:on
        ;
    }
...
static class PersonController {
...
        @DeleteMapping
        List<String> deletePersons() {
            return Arrays.asList("Jane", "Jason", "John");
        }

这是一个错误还是我错过了一个功能？
