this is index.adoc
= blog
:doctype: book
:icons: font
:source-highlighter: highlightjs
== /hello: Say "Hello World!"
operation::hello[]
.request
include::{snippets}/hello/http-request.adoc[]
.response
include::{snippets}/hello/http-response.adoc[]
this is my test class
#SpringBootTest
#AutoConfigureMockMvc
#ExtendWith({RestDocumentationExtension.class, SpringExtension.class})
public class HelloControllerTest {
private MockMvc mockMvc;
#BeforeEach
public void setUp(WebApplicationContext webApplicationContext,
RestDocumentationContextProvider restDocumentation) {
this.mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
.apply(documentationConfiguration(restDocumentation))
.build();
}
#Test
public void hello() throws Exception {
mockMvc.perform(get("/hello").param("name", "imckh"))
.andExpect(status().isOk())
.andDo(print())
.andExpect(jsonPath("$.msg", "Hello imckh!").exists())
.andDo(document("hello",
requestParameters(parameterWithName("name").description("The name to retrieve")),
responseFields(
fieldWithPath("code").description("Code of the response"),
fieldWithPath("msg").description("Message of the response"))
));
}
}
When i done testing, it can generate some *.adoc files like 'http-request.adoc, http-response.adoc',
generated-snippets
then i use maven package, it do can generate a index.html, but it cannot parse below
operation::hello[]
.request
include::{snippets}/hello/http-request.adoc[]
.response
include::{snippets}/hello/http-response.adoc[]
generated docs
It get wrong in this step: Including multiple snippets for an operation
Thanks.

You are using version 2.0.0-RC.1 of asciidoctor-maven-plugin with which spring-restdocs-asciidoctor is not compatible. Unfortunately, that incompatibility results in a silent failure to resolve the generated snippets. If you downgrade to 1.6.0 you will at least see a failure caused by the incompatibility.
You can avoid the problem by using a 1.5.x version of asciidoctor-maven-plugin with which spring-restdocs-asciidoctor in compatible. At the time of writing, 1.5.8 is the latest version. Things work as expected with this version.
You may also be interested in this Spring REST Docs issue which will hopefully figure out what to do about the breaking changes in AsciidoctorJ once the dust has settled a bit.
