一、Swagger2介绍
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。
1.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)
2.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)
3.一致性 (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)
4.可测性 (直接在接口文档上进行测试,以方便理解业务)
二、配置Swagger2
1、创建common模块
在guli-parent下创建模块common
配置:
groupId:com.atguigu
artifactId:common

2、在common中引入相关依赖
<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>
3、在common下面创建子模块service-base

4、在模块service-base中,创建swagger的配置类
创建包com.atguigu.servicebase.config,创建类SwaggerConfig
@Configuration
@EnableSwagger2
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("Helen", "http://atguigu.com", "55317332@qq.com"))
.build();
}
}
5、在模块service模块中引入service-base
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>service-base</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
6、在service_edu中启动类上加注解
使项目启动时扫描到包并加载
@SpringBootApplication
@ComponentScan(basePackages = {"com.caiweiwei"})
public class EduApplication {
public static void main(String[] args) {
SpringApplication.run(EduApplication.class,args);
}
}
7、API模型
可以添加一些自定义设置,例如:
定义样例数据
@ApiModelProperty(value = "创建时间", example = "2019-01-01 8:00:00")
@TableField(fill = FieldFill.INSERT)
private Date gmtCreate;
@ApiModelProperty(value = "更新时间", example = "2019-01-01 8:00:00")
@TableField(fill = FieldFill.INSERT_UPDATE)
private Date gmtModified;
8、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(description="讲师管理")
@RestController
@RequestMapping("/admin/edu/teacher")
public class TeacherAdminController {
@Autowired
private TeacherService teacherService;
@ApiOperation(value = "所有讲师列表")
@GetMapping
public List<Teacher> list(){
return teacherService.list(null);
}
@ApiOperation(value = "根据ID删除讲师")
@DeleteMapping("{id}")
public boolean removeById(
@ApiParam(name = "id", value = "讲师ID", required = true)
@PathVariable String id){
return teacherService.removeById(id);
}
}
