spring boot 2.0 集成swagger2

1.添加依赖

<dependency>
  <groupId>io.springfox</groupId>
 <artifactId>springfox-swagger2</artifactId>
  <version>2.7.0</version>
</dependency>
<dependency>
   <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger-ui</artifactId>
  <version>2.7.0</version>
</dependency>

2.创建配置类

Swagger需要一个配置类来进行对swagger的基本配置

import org.springframework.beans.factory.annotation.Autowired;
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.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**
* Swagger2的接口配置
*/
@Configuration
@EnableSwagger2
public class SwaggerConfig {

   /**
    * 创建API
    * @return
    */
   @Bean
   public Docket createRestApi() {
       return new Docket(DocumentationType.SWAGGER_2)
               //详细定制
               .apiInfo(apiInfo())
               .select()
               //.apis(RequestHandlerSelectors.basePackage("com.ruoyi.project.*.*.controller"))
               //扫描所有
               .apis(RequestHandlerSelectors.any())
               .paths(PathSelectors.any())
               .build();
   }

   private ApiInfo apiInfo() {
       // 用ApiInfoBuilder进行定制
       return new ApiInfoBuilder()
               .title("系统接口列表")
               .description("API接口测试平台\",\n" +
                       "                \"提供后台所有Restful接口\",")
               .termsOfServiceUrl("http://localhost/swagger-ui.html")
               .contact(new Contact(Yzz, "https://gitee.com/y_project/RuoYi", "[email protected]"))
               .version("1.1.0")
               .build();
   }
}

3.配置WebMvcConfigurerAdapter (重要)

@Configuration
public class ResourcesConfig extends WebMvcConfigurerAdapter{
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry)
    {
        /**swagger配置*/
        registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}
