springfox-swagger有什么用？
- 自動生成restAPI文檔
- 文檔在線查看／在線調試
- 隨著代碼自動更新
- 自動生成客戶端代碼
- 自動生成server模擬代碼
openAPI-specification/swagger/springfox
openAPI-specification 是一套描述REST API的規(guī)范
swagger 是實現(xiàn)openAPI-specification的一套工具瑞凑。是個具體實現(xiàn)
springfox 原名swagger-springmvc 是對swagger的java spring的集成祝钢。 目前也可以兼容swagger之外的規(guī)范照弥，例如RAML和jsonapi铺厨。
swagger 1和 swagger 2的區(qū)別
swagger1 指的是 OpenAPI Spec用的是1.2版本
swagger2 指的是 OpenAPI Spec用的是2.0版本
springfox-swagger2 對應的 swagger-core 版本是 1.5.3- 1.5.4

springfox-swagger2
-
引入jar包
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.x.x</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.x.x</version> </dependency> -
全局配置boot
@SpringBootApplication @EnableSwagger2 public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } @Bean public Docket testApi() { ApiInfo apiInfo = new ApiInfoBuilder() .title("API接口") .description("api") .build(); return new Docket(DocumentationType.SWAGGER_2) .groupName("default") .genericModelSubstitutes(DeferredResult.class) .useDefaultResponseMessages(false) .forCodeGeneration(true) .pathMapping("/") .select() .build() .apiInfo(apiInfo); } } -
全局配置非boot
@Configuration @EnableWebMvc @EnableSwagger2 public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } @Bean public Docket testApi() { ApiInfo apiInfo = new ApiInfoBuilder() .title("API接口") .description("api") .build(); return new Docket(DocumentationType.SWAGGER_2) .groupName("default") .genericModelSubstitutes(DeferredResult.class) .useDefaultResponseMessages(false) .forCodeGeneration(true) .pathMapping("/") .select() .build() .apiInfo(apiInfo); } } -
配置controller
@Api(tags = {"測試組"}) @RestController public class Controller { @ApiOperation(value = "方法1", notes = "方法1描述") @RequestMapping(value = "/CH070", method = {RequestMethod.POST} , produces = {"application/json","application/xml"}) public Response method1(@ApiParam(required = true, value = "參數(shù)1") @RequestParam(value = "method11") String method2 , @ApiParam(required = true, value = "method2") @RequestParam(value = "method2", required = true) String method2) { } } -
集成 spring-data-rest / bean-validators
<dependency> <groupId>io.springfox</groupId> <artifactId>springfox-bean-validators</artifactId> <version>${springfox.version}</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-data-rest</artifactId> <version>${springfox.version}</version> <dependency>@Import({SpringDataRestConfiguration.class, BeanValidatorPluginsConfiguration.class})
springfox-swagger-ui
swagger-ui 是一個node工程窍株，通過swagger暴露的接口，展示文檔信息
springfox-swagger-ui 是一個webjar, 方便進行maven集成
springfox-ui 目錄結構：
```
META-INF
|- resources
|- webjars
|-swagger-ui.html
|-springfox-swagger-ui
|-css
|-fonts
|-images
|-lang
|-lib
|-o2c.html
|-springfox.js
|-swagger-ui.min.js
```
什么是webjar敞峭？
第三方小工具, 把靜態(tài)資源進行打包踊谋，幷版本化管理。
-
spring-boot 默認支持旋讹。
//WebMvcAutoConfiguration#addResourceHandlers if (!registry.hasMappingForPattern("/webjars/**")) { customizeResourceHandlerRegistration( registry.addResourceHandler("/webjars/**") .addResourceLocations( "classpath:/META-INF/resources/webjars/") .setCachePeriod(cachePeriod)); } -
非spring-boot
<mvc:resources mapping="/swagger-ui.html" location="classpath:/META-INF/resources/"/> <mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>
其他風格的替代品：
swagger-codegen
swagger-codegen這個是總入口殖蚕。不過文檔比較亂，不太好找沉迹，下面列出幾個關鍵點
從哪里獲得輸入的配置文件睦疫？
-
springfox-swagger-ui 默認輸出地址為/v2/api-docs?group=default。
group可以自定義鞭呕，default group可以不傳蛤育。 通過瀏覽器地址欄請求可能無法接受json格式的返回報文，這時可以通過更改spring-boot配置項springfox.documentation.swagger.v2.path 添加后綴解決葫松，例如：/v2/api-docs.json#springfox.documentation.swagger2.web.Swagger2Controller public static final String DEFAULT_URL = "/v2/api-docs"; @RequestMapping( value = DEFAULT_URL, method = RequestMethod.GET, produces = { APPLICATION_JSON_VALUE, HAL_MEDIA_TYPE }) @PropertySourcedMapping( value = "${springfox.documentation.swagger.v2.path}", propertyKey = "springfox.documentation.swagger.v2.path") @ResponseBody public ResponseEntity<Json> getDocumentation( @RequestParam(value = "group", required = false) String swaggerGroup, HttpServletRequest servletRequest) { 在線生成 https://generator.swagger.io/ 貌似需要把配置文件暴露到外網(wǎng)
swagger-codegen-maven-plugin maven 自動化集成
具體有哪些配置項 源碼 文檔沒怎么說瓦糕，源碼里有列表。腋么。
