离线API文档

本文主要讲解如何在springboot下整合Swagger2 API离线文档。

本教程在Demo07基础上添加Swagger2 API离线文档配置信息

添加依赖

引入 springfox-staticdocs、spring-restdocs-mockmvc 依赖：

<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-staticdocs</artifactId>
  <version>2.6.1</version>
  <scope>test</scope>
</dependency>

<dependency>
  <groupId>org.springframework.restdocs</groupId>
  <artifactId>spring-restdocs-mockmvc</artifactId>
  <version>2.0.2.RELEASE</version>
  <scope>test</scope>
</dependency>

添加依赖

MAVEN属性配置

<swagger2markup.version>1.3.1</swagger2markup.version>
<swagger.output.dir>${project.build.directory}/asciidoc/json</swagger.output.dir>
<swagger.snippetOutput.dir>${project.build.directory}/asciidoc/snippets</swagger.snippetOutput.dir>
<generated.asciidoc.directory>${project.build.directory}/asciidoc/generated</generated.asciidoc.directory>
<asciidoctor.html.output.directory>${project.build.directory}/asciidoc/html</asciidoctor.html.output.directory>
<swagger.input>${swagger.output.dir}/swagger.json</swagger.input>

MAVEN属性配置

添加插件配置

<!-- 以下用于生成adoc文件的配置 -->
<plugin>
    <groupId>io.github.swagger2markup</groupId>
    <artifactId>swagger2markup-maven-plugin</artifactId>
    <version>${swagger2markup.version}</version>
    <dependencies>
        <dependency>
            <groupId>io.github.swagger2markup</groupId>

            </goals>
        </execution>
    </executions>
</plugin>

<!--此插件生成HTML-->
<plugin>
  <groupId>org.asciidoctor</groupId>

添加插件配置

编写测试类

在com/heardfate/springboot/demo/Swagger2MarkupTest.java下添加测试类

package com.heardfate.springboot.demo;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.mock.web.MockHttpServletResponse;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import java.nio.file.Files;
import java.nio.file.Paths;

import static org.springframework.restdocs.mockmvc.RestDocumentationRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

  /**
   * @since: 2018/11/4
   * @author: Mr.HeardFate
   */
  @RunWith(SpringRunner.class)
  @SpringBootTest
  public class Swagger2MarkupTest {
	@Autowired
	private WebApplicationContext context;

	private MockMvc mockMvc;

	@Before
	public void setUp() {
		this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context).build();
	}

	@Test
	public void createSpringfoxSwaggerJson() throws Exception {
	  String outputDir = "target/asciidoc/json";
	  //将api-docs的json数据写入文件
	  MvcResult mvcResult = this.mockMvc.perform(get("/v2/api-docs")
		  .accept(MediaType.APPLICATION_JSON))
		  .andExpect(status().isOk())
		  .andReturn();

	  //将获取的JSON写入文件
	  MockHttpServletResponse response = mvcResult.getResponse();
	  String swaggerJson = response.getContentAsString();
	  Files.createDirectories(Paths.get(outputDir));
	  Files.write(Paths.get(outputDir, "swagger.json"), swaggerJson.getBytes());

	  //将多个ADOC整合成一个INDEX.ADOC文件
	  String generated = "target/asciidoc/generated";
	  Files.createDirectories(Paths.get(generated));
	  Files.write(Paths.get(generated, "index.adoc"), ("include::overview.adoc[]\ninclude::definitions" +
			".adoc[]\ninclude::paths.adoc[]").getBytes());
	}
}
