Swagger -----自动生成接口文档

测试demo:Spring+SpringMvc+Mybatis-Plus+SpringBoot+RESTful风格Api +Maven

1，引入依赖

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

2，SwaggerConfig

package com.mangoubiubiu.config;

import com.google.common.base.Predicates;
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.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;

@Configuration//配置类
@EnableSwagger2//swagger注解
public class SwaggerConfig {

    @Bean
    public Docket webApiConfig(){
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("webApi")
                .apiInfo(webApiInfo())
                .select()
                //接口中包含admin error 就不显示
                .paths(Predicates.not(PathSelectors.regex("/admin/.*")))
                .paths(Predicates.not(PathSelectors.regex("/error.*")))
                .build();
    }


    private ApiInfo webApiInfo(){
        return new ApiInfoBuilder()
                .title("网站-课程中心API文档")
                .description("本文档描述了课程中心微服务接口定义")
                .version("1.0")
                .contact(new Contact("Mangoubiubiu", "https://www.cnblogs.com/mangoubiubiu/", "0000000000@qq.com"))
                .build();
    }

}

3,Controller

import io.swagger.annotations.ApiParam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.*;

import java.util.List;

        List<Teacher> records = pageInfo.getRecords();//所有的数据list

        return R.ok().data("total",total).data("rows",records);

    }
