springboot 에 swagger 설치해서 api 확인하자

swaggerConfig.java (이름이야뭐..아무거나..) 를 만들어서

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration@EnableSwagger2public class SwaggerConfig {

    @Bean    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.any()) //모든 url 리스트 찾아내줘 스웍                .paths(PathSelectors.any()) // 모든 패스 전부.                .build();
    }
}

이것만으로 잘 안되서..

@Overridepublic void addViewControllers(ViewControllerRegistry registry) {
    registry.addRedirectViewController("/api/v2/api-docs", "/v2/api-docs");
    registry.addRedirectViewController("/api/swagger-resources/configuration/ui", "/swagger-resources/configuration/ui");
    registry.addRedirectViewController("/api/swagger-resources/configuration/security", "/swagger-resources/configuration/security");
    registry.addRedirectViewController("/api/swagger-resources", "/swagger-resources");
}

@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/api/swagger-ui.html**").addResourceLocations("classpath:/META-INF/resources/swagger-ui.html");
    registry.addResourceHandler("/api/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
...
}

했더니 localhost:8080/api/swagger-ui.html 에서 보게 되었다.
