Swagger+spring boot 转换为html,PDF文
前言
使用Swagger将Restlet APIs转换为html和PDF文档。
主要是使用Swagger2Markup。官网提供了两种方式:
You can use Swagger2Markup to convert your contract-first Swagger YAML file into a human-readable format and combine it with hand-written documentation.
-
you can choose the code-first approach and use Swagger2Markup together with Swagger JAX-RS, springfox or spring-restdocs.
-
If you are Gradle or Maven user, you can also use the Swagger2Markup Gradle Plugin or Swagger2markup Maven Plugin.
我所使用的环境:Spring Boot + Gradle。
所以我使用的Swagger 是 springfox,如果你是Restlet JAX-RS等,可以使用restlet-framework(这些都可以在swagger的开源集合中找到)。
由于我的项目使用的是Gradle构建的,所以我使用的是Swagger2Markup Gradle Plugin。
官网提供了一个完整的Demo,可以生成html和pdf:http://swagger2markup.github.io/swagger2markup/1.3.1/#_demo
官方Demo是使用Swagger2Markup Gradle Plugin插件生成的,当然你也可以使用MAVEN插件,插件的使用例子如下:
Swagger2Markup Gradle Plugin:https://github.com/Swagger2Markup/swagger2markup-gradle-project-template
Swagger2Markup Maven Plugin:https://github.com/Swagger2Markup/swagger2markup-maven-project-template
转换为 html或PDF的步骤
- 通过编写junit测试类生成一个实时的swagger.json。
- 将swagger.json转换为AsciiDoc。
- 增加AsciiDoc相关文档,具体可以参考Swagger2Markup Gradle Plugin或Swagger2Markup Maven Plugin文档。
- 将生成的asciiDoc通过AsciiDoc plugin转换为HTML和PDF.
- 将生成的html和pdf拷贝到可执行的jar包中,并部署他就可以让外界访问了。

按照上述步骤开始编辑自己的应用。
1.在build.gradle中添加相关依赖和插件
buildscript {
repositories {
mavenCentral()
//*********以下为swagger转换 pdf需要************//
jcenter()
maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local/' }
//*********以上为swagger转换 pdf需要************//
mavenLocal()
}
dependencies {
classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.4.0.RELEASE'
//*********以下为swagger转换 pdf需要************//
//asciidoc 插件
classpath 'org.asciidoctor:asciidoctor-gradle-plugin:1.5.3'
classpath 'org.asciidoctor:asciidoctorj-pdf:1.5.0-alpha.10.1'
//swagger2markup 插件
classpath 'io.github.swagger2markup:swagger2markup-spring-restdocs-ext:1.2.0'
classpath 'io.github.swagger2markup:swagger2markup-gradle-plugin:1.2.0'
//*********以上为swagger转换 pdf需要************//
}
}
apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'spring-boot'
//*********以下为swagger转换 pdf需要************//
apply plugin: 'org.asciidoctor.convert'
apply plugin: 'io.github.swagger2markup'
apply plugin: 'io.spring.dependency-management'
//*********以上为swagger转换 pdf需要************//
version = '1.2.0'
tasks.withType(JavaCompile) {
sourceCompatibility = "1.8"
targetCompatibility = "1.8"
options.deprecation = true
}
repositories {
mavenCentral()
//*********以下为swagger转换 pdf需要************//
jcenter()
maven { url 'https://repo.spring.io/snapshot' }
maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local/' }
//*********以上为swagger转换 pdf需要************//
mavenLocal()
}
ext {
//设置springfox版本
springfoxVersion = '2.5.0'
}
dependencies {
//json
compile "org.codehaus.jackson:jackson-mapper-asl:1.9.12"
/*fastjson*/
compile "com.alibaba:fastjson:1.1.39"
compile 'org.springframework.boot:spring-boot-starter-web'
compile 'org.springframework.boot:spring-boot-starter-actuator'
compile 'com.google.guava:guava:18.0'
compile 'net.logstash.logback:logstash-logback-encoder:4.5.1'
compile("com.fasterxml.jackson.dataformat:jackson-dataformat-smile:2.6.5")
compile("com.fasterxml.jackson.module:jackson-module-afterburner:2.6.5")
//*********以下为swagger转换 pdf需要************//
compile 'io.swagger:swagger-annotations:1.5.6'
compile group: 'io.springfox', name: 'springfox-swagger2', version: '2.6.1'
compile group: 'io.springfox', name: 'springfox-swagger-ui', version: '2.6.1'
testCompile "io.springfox:springfox-bean-validators:${springfoxVersion}"
testCompile 'org.springframework.restdocs:spring-restdocs-mockmvc'
//*********以上为swagger转换 pdf需要************//
testCompile 'org.springframework.boot:spring-boot-starter-test'
testCompile 'junit:junit'
testCompile 'com.fasterxml.jackson.module:jackson-module-jsonSchema:2.6.5'
}
2.在build.gradle中设置swagger.json和asciiDoc生成路径,且配置到SystemProperty中,方便代码中使用。
ext {
//asciiDoc生成路径
asciiDocOutputDir = file("${buildDir}/asciidoc/generated")
//swagger.json生成路径
swaggerOutputDir = file("${buildDir}/swagger")
snippetsOutputDir = file("${buildDir}/asciidoc/snippets")
//设置springfox版本
springfoxVersion = '2.5.0'
}
test {
//设置一些systemProperty
systemProperty 'io.springfox.staticdocs.outputDir', swaggerOutputDir
systemProperty 'io.springfox.staticdocs.snippetsOutputDir', snippetsOutputDir
systemProperty 'io.springfox.staticdocs.asciiDocOutputDir',asciiDocOutputDir
}
3.编写测试类生成swagger.json
也可以直接生成asciiDoc,跳过生成swagger.json然后通过swagger.json生成asciiDoc这一步,具体代码请参考:http://swagger2markup.github.io/swagger2markup/1.3.1/#_spring_boot_and_springfox
@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@AutoConfigureRestDocs(outputDir = "build/asciidoc/snippets")
@SpringBootTest(classes = {CommonToolsApplication.class, SwaggerAutoConfiguration.class})
@AutoConfigureMockMvc
public class Swagger2MarkupTest {
private static final Logger LOG = LoggerFactory.getLogger(Swagger2MarkupTest.class);
@Autowired
private MockMvc mockMvc;
@Test
public void createSpringfoxSwaggerJson() throws Exception {
//String designFirstSwaggerLocation = Swagger2MarkupTest.class.getResource("/swagger.yaml").getPath();
//获取生成swagger.json路径,已经在build.gradle中配置
String outputDir = System.getProperty("io.springfox.staticdocs.outputDir");
//本项目api路径
MvcResult mvcResult = this.mockMvc.perform(get("/v2/api-docs")
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andReturn();
MockHttpServletResponse response = mvcResult.getResponse();
String swaggerJson = response.getContentAsString();
Files.createDirectories(Paths.get(outputDir));
try (BufferedWriter writer = Files.newBufferedWriter(Paths.get(outputDir, "swagger.json"), StandardCharsets.UTF_8)){
writer.write(swaggerJson);
}
}
}
其中CommonToolsApplication为spring boot 启动类,SwaggerAutoConfiguration为Swagger配置类
@SpringBootApplication
public class CommonToolsApplication {
public static void main(String[] args) {
SpringApplication.run(CommonToolsApplication.class, args);
}
}
@Configuration
@EnableSwagger2
public class SwaggerAutoConfiguration {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
//配置扫描的基础包
.apis(RequestHandlerSelectors.basePackage("com.ops.commons.web"))
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("Spring Boot中使用Swagger2构建RESTful APIs")
.description("Controller中入参最好使用SpringMVC注解:@RequestBody,@RequestParam,@PathVariable<br>"
+ "返回使用@ResponseBody或者ResponseEntity,区别:ResponseEntity可以包含Header和HttpStatus")
.version("1.0")
.build();
}
}
4.添加AsciiDoc相关文档
打开官方Demo。将src/doc/asciidoc下面的文件拷贝到自己项目中。
5.将swagger.json生成asciiDoc文件
当增加Swagger2Markup Gradle Plugin插件时,他会自动增加一个convertSwagger2markup任务,当然你可以覆盖他。
在build.gradle中覆写convertSwagger2markup task:
convertSwagger2markup {
//执行该task时先运行test,主要是运行Swagger2MarkupTest,让其生成swagger.json
dependsOn test
//入参为swagger.json
swaggerInput "${swaggerOutputDir}/swagger.json"
outputDir asciiDocOutputDir
config = [
'swagger2markup.pathsGroupedBy' : 'TAGS',
'swagger2markup.extensions.springRestDocs.snippetBaseUri': snippetsOutputDir.getAbsolutePath()]
}
6.将asciiDoc转换为html和PDF。
在build.gradle中添加
asciidoctor {
//依赖上面的swagger.json转换为asciiDoc任务,方便直接运行该任务时,先运行convertSwagger2markup
dependsOn convertSwagger2markup
sources {
include 'index.adoc'
}
backends = ['html5', 'pdf']
attributes = [
doctype: 'book',
toc: 'left',
toclevels: '3',
numbered: '',
sectlinks: '',
sectanchors: '',
hardbreaks: '',
generated: asciiDocOutputDir
]
}
7.将生成的html和PDF拷贝到项目中
因为生成的文件时放在build下面的,拷贝到项目中,当启动了项目后,用户可以直接通过浏览器查看
jar {
dependsOn asciidoctor
//将生成的html和PDF拷贝到项目中
from ("${asciidoctor.outputDir}/html5") {
into 'static/docs'
}
from ("${asciidoctor.outputDir}/pdf") {
into 'static/docs'
}
}
ok,完成。
现在你可以运行gradle clean asciidoctor命令,查看生成的文档了,html路径:build\asciidoc\html5;pdf路径:build\asciidoc\pdf。
