①:配置Swagger2生成API接口文档

1. 概述

​ 前后端分离开发模式中,api文档是最好的沟通方式。Swagger 是一个规范和完整的框架,用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。及时性 (接口变更后,能够及时准确地通知相关前后端开发人员)规范性 (并且保证接口的规范性,如接口的地址,请求方式,参数及响应格式和错误信息)一致性 (接口信息一致,不会出现因开发人员拿到的文档版本不一致,而出现分歧)可测性 (直接在接口文档上进行测试,以方便理解业务)

2. 配置Swagger2

(1)在classRoom_parent下创建子模块common

配置Swagger2生成API接口文档

(2)在common模块引入依赖 并删除common中的src目录

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <scope>provided </scope>
    </dependency>

    <!--mybatis-plus-->
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
        <scope>provided </scope>
    </dependency>

    <!--lombok用来简化实体类:需要安装lombok插件-->
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>

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

    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
    </dependency>
</dependencies>

(3)在common下创建子模块service_utils

(4)在service_utils创建swagger2配置类
配置Swagger2生成API接口文档

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
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
@EnableSwagger2
public class Swagger2Config {
    @Bean
    public Docket webApiConfig(){
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("ggkt")
                .apiInfo(webApiInfo())
                .select()
                //只显示api路径下的页面
                //.paths(Predicates.and(PathSelectors.regex("/api/.*")))
                .build();
    }

    private ApiInfo webApiInfo(){
        return new ApiInfoBuilder()
                .title("网站-API文档")
                .description("本文档描述了网站微服务接口定义")
                .version("1.0")
                .contact(new Contact("it", "http://it.com", "it.com"))
                .build();
    }
}

(5)在service模块引入service_utils依赖

<dependency>
    <groupId>com.it</groupId>
    <artifactId>service_utils</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

(6)在service_vod启动类上添加注解,进行测试
配置Swagger2生成API接口文档

@SpringBootApplication
@ComponentScan("com.it")
public class ServiceVodApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServiceVodApplication.class, args);
    }
}

3. 定义接口说明和参数说明

定义在类上:@Api

定义在方法上:@ApiOperation

定义在参数上:@ApiParam

@Api(tags = "讲师管理接口")
@RestController
@RequestMapping(value="/admin/vod/teacher")
public class TeacherController {

    @Autowired
    private TeacherService teacherService;

    //删除讲师
    @ApiOperation("逻辑删除讲师")
    @DeleteMapping("{id}")
    public boolean removeById(@ApiParam(name = "id", value = "ID", required = true) @PathVariable String id){
        return teacherService.removeById(id);
    }

    //查询所有讲师列表
    @ApiOperation("所有讲师列表")
    @GetMapping("findAll")
    public List<Teacher> findAll(){
        List<Teacher> list = teacherService.list();
        return list;
    }
}

4. swagger2测试

(1)浏览器输入固定地址 http://localhost:8301/swagger-ui.html

(2)测试接口

(3)执行接口
