Spring Boot整合Swagger2

• Maven依赖

<!-- swagger api -->
   <dependency>
       <groupId>io.springfox</groupId>
       <artifactId>springfox-swagger2</artifactId>
       <version>2.9.2</version>
   </dependency>
   <dependency>
       <groupId>io.springfox</groupId>
       <artifactId>springfox-swagger-ui</artifactId>
       <version>2.9.2</version>
   </dependency>

• Docket配置

package org.sang.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
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
@EnableSwagger2
public class SwaggerConfig {

    @Value(value = "${springfox.swagger.enable}")
    private boolean swaggerEnable;


    @Bean
    Docket docket() {
        System.out.println("swaggerEnable:" + swaggerEnable);
        return new Docket(DocumentationType.SWAGGER_2)
                .enable(swaggerEnable)
                .select()
                .apis(RequestHandlerSelectors.basePackage("org.sang.controller"))
                .paths(PathSelectors.any())
                .build()
                .apiInfo(new ApiInfoBuilder()
                    .description("SwaggerApi测试文档")
                    .version("v1.0")
                    .title("Api测试文档")
                    .build()
                );
    }

}

• 让SpringMVC DispatchServlet找到Swagger对应的资源

public class MyWebMvcConfig implements WebMvcConfigurer {
   /**
     * 让DispatchServlet找到Swagger对应的资源
     * 否则：No mapping found for HTTP request with URI [/swagger-ui.html]
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}
