springBoot(12)---整合Swagger2

Spingboot整合Swagger2

随着互联网技术的发展,一般开发都是前后端分离,那么前端和后端的唯一联系,变成了API接口;API文档变成了前后端开发人员联系的纽带,变得越来越重要,没有API

文档工具之前,大家都是手写API文档的,在什么地方书写的都有,有在confluence上写的,有在对应的项目目录下readme.md上写的,每个公司都有每个公司的玩法,无所谓好

坏。但都有一个很大的诟病就是,如果你的接口改动了,那你必须记得去改你的API文档,而Swagger并不需要。swagger就是一款让你更好的书写API文档的框架。

一、项目搭建

1、pom.xml

        <dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency> <dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>

2、application.yml

server:
port: 8086 #代表当前环境是dev环境
spring:
profiles:
active: dev

3、Swagger2DevConfig(配置类)

注意添加@EnableSwagger2注解,这个注解也可以加在springboot启动类上

@Configuration
@EnableSwagger2
public class Swagger2DevConfig { //默认pro环境
@Profile({"default", "pro"})
@Bean
public Docket createWebApi() {
return new Docket(DocumentationType.SWAGGER_2).enable(false).select().build();
} //dev环境接口访问地址:http://localhost:8086/swagger-ui.html
@Profile("dev")
@Bean
public Docket createWebApiDev() {
return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfoDev()).select()
.apis(RequestHandlerSelectors.withClassAnnotation(Api.class)).paths(PathSelectors.any()).build();
} //测试环境接口访问地址: test.jincou.com/user/swagger-ui.html
@Profile("test")
@Bean
public Docket createWebApiTest() {
return new Docket(DocumentationType.SWAGGER_2).host("test.jincou.com/user")
.protocols(Sets.newHashSet("https")).apiInfo(apiInfoDev()).select()
.apis(RequestHandlerSelectors.withClassAnnotation(Api.class)).paths(PathSelectors.any()).build();
} private ApiInfo apiInfoDev() {
return new ApiInfoBuilder().title("用户模块API").description(
"用户api接口文档\n" + "\n" + "测试环境:https://test.jincou.com/user\n").contact(new Contact("张三", "", ""))
.version("1.0").build();
}
}

4、PersonController

这里提供了两个接口

@Api(tags = "用户相关接口")
@RestController
@RequestMapping(value = "/web/api/person")
public class PersonController { @ApiOperation(value = "用户详细信息", notes = "通过id获得用户详细信息")
@ApiImplicitParams({
@ApiImplicitParam(name = "id", value = "用户ID", required = true, paramType = "query", defaultValue = "0")})
@RequestMapping(value="page",method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_UTF8_VALUE )
public Person getById(@RequestParam(value="id",defaultValue = "0") Long id){
return new Person(id,2,"小小","杭州");
} //大咖分页列表
@ApiOperation(value = "删除用户信息", notes = "通过ID删除用户信息")
@ApiImplicitParams({
@ApiImplicitParam(name = "id", value = "用户ID", required = true, paramType = "query", defaultValue = "0")})
@RequestMapping(value="delete",method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_UTF8_VALUE )
public String delete(@RequestParam(value="id",defaultValue = "0") Long id){ return "删除成功";
}
}

5、Person实体类

@ApiModel(description = "用户详细信息")
public class Person { @ApiModelProperty(value = "用户Id", position = 1)
private Long id; @ApiModelProperty(value = "用户年龄", position = 2)
private int age; @ApiModelProperty(value = "用户姓名", position = 3)
private String name; @ApiModelProperty(value = "用户所在城市", position = 4)
private String city; public Person(Long id,int age,String name,String city){
this.id=id;
this.age=age;
this.city=city;
this.name=name;
}
//提供get和set方法
}

6、本地启动测试

访问:http://localhost:8086/swagger-ui.html。
