Migrating from SpringFox

• Remove springfox and swagger 2 dependencies. Add springdoc-openapi-ui dependency instead.

   
      org.springdoc
      springdoc-openapi-ui
      @springdoc.version@
   

• Replace swagger 2 annotations with swagger 3 annotations (it is already included with springdoc-openapi-ui dependency). Package for swagger 3 annotations is io.swagger.v3.oas.annotations.

  • @ApiParam -> @Parameter
  • @ApiOperation -> @Operation
  • @Api -> @Tag
  • @ApiImplicitParams -> @Parameters
  • @ApiImplicitParam -> @Parameter
  • @ApiIgnore -> @Parameter(hidden = true) or @Operation(hidden = true) or @Hidden
  • @ApiModel -> @Schema
  • @ApiModelProperty -> @Schema

• This step is optional: Only if you have multiple Docket beans replace them with GroupedOpenApi beans.

  Before:

      @Bean
      public Docket publicApi() {
          return new Docket(DocumentationType.SWAGGER_2)
                  .select()
                  .apis(RequestHandlerSelectors.basePackage("org.github.springshop.web.public"))
                  .paths(PathSelectors.regex("/public.*"))
                  .build()
                  .groupName("springshop-public")
                  .apiInfo(apiInfo());
      }
  
      @Bean
      public Docket adminApi() {
          return new Docket(DocumentationType.SWAGGER_2)
                  .select()
                  .apis(RequestHandlerSelectors.basePackage("org.github.springshop.web.admin"))
                  .paths(PathSelectors.regex("/admin.*"))
                  .build()
                  .groupName("springshop-admin")
                  .apiInfo(apiInfo());
      }
  

  Now:

      @Bean
      public GroupedOpenApi publicApi() {
          return GroupedOpenApi.builder()
                  .setGroup("springshop-public")
                  .pathsToMatch("/public/**")
                  .build();
      }
  
      @Bean
      public GroupedOpenApi adminApi() {
          return GroupedOpenApi.builder()
                  .setGroup("springshop-admin")
                  .pathsToMatch("/admin/**")
                  .build();
      }
  

  If you have only one Docket -- remove it and instead add properties to your application.properties:

  springdoc.packagesToScan=package1, package2
  springdoc.pathsToMatch=/v1, /api/balance/**
  

• Add bean of OpenAPI type. See example:

      @Bean
      public OpenAPI springShopOpenAPI() {
          return new OpenAPI()
                  .info(new Info().title("SpringShop API")
                  .description("Spring shop sample application")
                  .version("v0.0.1")
                  .license(new License().name("Apache 2.0").url("http://springdoc.org")))
                  .externalDocs(new ExternalDocumentation()
                  .description("SpringShop Wiki Documentation")
                  .url("https://springshop.wiki.github.org/docs"));
      }
