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)。
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.service_base.config,创建类SwaggerConfig
package com.atguigu.servicebase.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
@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启动类上添加注解
package com.atguigu.eduservice;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@ComponentScan(basePackages={"com.atguigu"})
public class EduApplication {
public static void main(String[] args) {
SpringApplication.run(EduApplication.class, args);
}
}
7、根据URL访问,进行测试
http://localhost:8001/swagger-ui.html
8、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;
9、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);
}
}
