Swagger2的配置和使用

springboot快速整合Swagger2

1. 添加maven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. 添加SpringBoot配置

package jweb.system.config;

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;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**
 * Created by Laichj on 2018/1/3.
 */
@Configuration
@EnableSwagger2
public class Swagger2 {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("jweb.account.controller"))
                .paths(PathSelectors.any())
                .build();
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Spring Boot中使用Swagger2构建RESTful APIs")
                .description("Swagger2配置")
                .termsOfServiceUrl("http://aposs.cn/")
                .version("2.7.0")
                .build();
    }

}

- 添加文档内容

常用的注解有：
@ApiOperation
@ApiImplicitParams
@ApiImplicitParam

配置后启动项目，访问
http://host:port/swagger-ui.html
查看项目API

如果出现以下错误：

Unable to infer base url. This is common when using dynamic servlet registration or when the API is behind an API Gateway. The base url is the root of where all the swagger resources are served. For e.g. if the api is available at http://example.org/api/v2/api-docs then the base url is http://example.org/api/. Please enter the location manually:

则需要在Application中添加@EnableSwagger2 注解
