@SpringBootApplication
public class Application {

  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }
}

@RestController
public class HomeController {

  @GetMapping("/")
  public Map<String, Object> greeting() {
    return Collections.singletonMap("message", "Hello World");
  }

}

{“message”:”Hello World”}

@RunWith(SpringRunner.class)
@WebMvcTest(HomeController.class)
@AutoConfigureRestDocs(outputDir = "target/snippets")
public class WebLayerTest {

  @Autowired
  private MockMvc mockMvc;

  @Test
  public void shouldReturnDefaultMessage() throws Exception {
    this.mockMvc.perform(get("/")).andDo(print()).andExpect(status().isOk())
        .andExpect(content().string(containsString("Hello World")))
        .andDo(document("home"));
  }
}

└── target
  └── snippets
    └── home
      └── httpie-request.adoc
      └── curl-request.adoc
      └── http-request.adoc
      └── http-response.adoc

用 Spring REST Docs 构建文档

This is an example output for a service running at http://localhost:8080:

.request
include::{snippets}/home/http-request.adoc[]

.response
include::{snippets}/home/http-response.adoc[]

这个例子非常简单，通过单元测试和一些简单的配置就能够得到api文档了。
