整合swagger

一.简介

使用swagger的好处

1.生成在线接口文档

2.方便接口测试

二.创建步骤

1.创建一个公共子模块common,并引入依赖

<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>
        <scope>provided</scope>
    </dependency>
    <!--swagger-->
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <scope>provided</scope>
    </dependency>
    <!-- redis -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
    <!-- spring2.X集成redis所需common-pool2
    <dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>2.6.0</version>
    </dependency>-->
</dependencies>

2.在common中再创建一个子模块，service-base

3.在service-base中创建一个配置类SwaggerConfig

@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()
                .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("java", "http://atguigu.com", "[email protected]"))
                .build();
    }
}

4.service-edu使用service_base,故需要在service.pom中引用依赖

<dependency>
    <groupId>com.sidney</groupId>
    <artifactId>service_base</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

5.在service-edu启动类中设置包扫描规则@ComponentScan(basePackages = {"com.sidney"})，从而扫描到配置类SwaggerConfig，若不改只能扫描当前项目中的类

@SpringBootApplication
@ComponentScan(basePackages = {"com.sidney"})
public class EduApplication {
    public static void main(String[] args) {
      SpringApplication.run(EduApplication.class,args);

    }
}

6.swagger访问地址

http://localhost:8001/swagger-ui.html

界面会列出可测试的接口

7.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

/**
 * <p>
 * 讲师 前端控制器
 * </p>
 *
 * @author Sidney
 * @since 2020-05-01
 */
@Api(description = "讲师管理")
@RestController
@RequestMapping("/eduservice/teacher")
public class EduTeacherController {

    @Autowired
    private EduTeacherService teacherService;

    @ApiOperation(value = "所有讲师列表")
    //查询讲师表所有数据
    @GetMapping("/findAll")
    public R findAllTeacher() {
        List<EduTeacher> list = teacherService.list(null);
        return R.ok().data("items", list);
    }

    //逻辑删除讲师的方法
    @ApiOperation(value = "根据ID删除讲师")
    @DeleteMapping("{id}") //id需要通过路径传递
    public R removeTeacher(@ApiParam(name = "id", value = "讲师ID", required = true) @PathVariable String id) {
        boolean b = teacherService.removeById(id);

        if (b){
            return R.ok();
        }else {
            return R.error();

        }
    }

}
