Spring Rest文档无法使用WebTestClient记录pathParameters

如何解决Spring Rest文档无法使用WebTestClient记录pathParameters

升级到Spring-test-5.3.0-SNAPSHOT后，spring rest文档由于无法找到urlTemplate而抱怨未能记录路径参数。

webTestClient.mutateWith(csrf()).get()
        .uri("/products/{productId}",productId)
        .accept(MediaType.APPLICATION_JSON)
        .exchange()
        .expectStatus().isOk()
        .expectHeader().contentType(MediaType.APPLICATION_JSON)
        .expectBody()
        .consumeWith(document("find-product-by-id",pathParameters(
                        parameterWithName("productId").description("...")
                ),responseFields(getProductResponseFields())));

错误日志：

好像DefaultWebTestClient在构造uri时将uriTemplate设置为null，但是找不到覆盖它的方法。

解决方法

不幸的是，最新的Spring Framework 5.3快照中存在回归，我不认为您可以解决它。我提出了Spring Framework issue。同时，您可以使用Spring Framework 5.3.0.RC1，因为它是在引入问题之前发布的。
