swagger2 配置

1、配置Maven依赖

<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>

2、新建SwaggerConfig类

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.service.ApiKey;
import springfox.documentation.service.AuthorizationScope;
import springfox.documentation.service.SecurityReference;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spi.service.contexts.SecurityContext;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import java.util.List;

import static com.google.common.collect.Lists.newArrayList;

/**
 * @author lism
 */
@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2).
                useDefaultResponseMessages(false)
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.regex("^(?!auth).*$"))
                .build()
                .securitySchemes(securitySchemes())
                .securityContexts(securityContexts())
                ;
    }
    private List<ApiKey> securitySchemes() {
        return newArrayList(
                new ApiKey("Authorization", "Authorization", "header"));
    }
    private List<SecurityContext> securityContexts() {
        return newArrayList(
                SecurityContext.builder()
                        .securityReferences(defaultAuth())
                        .forPaths(PathSelectors.regex("^(?!auth).*$"))
                        .build()
        );
    }
    private List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return newArrayList(
                new SecurityReference("Authorization", authorizationScopes));
    }
}

3、在启动类上加入 @EnableSwagger2 注解

4、登录 http://localhost:8080/swagger-ui.html，也就可以看到所有写的接口了，大功告成
