springboot配置swagger2线上文档

1、先上项目配置好的swagger2的ui界面：

2、需要swagger2的这两个包：

        <!-- swagger2 包 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>${springfox-swagger2-version}</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>${springfox-swagger2-version}</version>
        </dependency>

3、然后需要写配置swagger2的代码类：

代码内容如下：

package com.example.cloudorderdemo.config;

import io.swagger.annotations.Api;
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.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

@Configuration
public class SwaggerConfig {

　　//application.yml中配置的version
    @Value("${info.app.version}")
    private String version;

//application.yml中配置的应用名称
    @Value("${spring.application.name}")
    private String applicationName;

    @Bean
    public Docket createRestApi(){//如果在application.yml中配置了项目访问路径userdemo就要在swagger访问路径的端口后面加上 /userdemo/

        //最新：swagger的访问路径：http://localhost:8880/swagger-ui.html#

        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).enable(true)
                .select()
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                .paths(PathSelectors.any())
                .build()
                .apiInfo(apiInfo());
    }

    private ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                .title("order订单服务")
                .version(version)
                .build();
    }

}
