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。
