一直以来做对外的接口文档都比较原始,基本上都是手写的文档传来传去,最近发现了一个新玩具,可以在接口上省去不少麻烦。
swagger是一款方便展示的API文档框架。它可以将接口的类型最全面的展示给对方开发人员,避免了手写文档的片面和误差行为。
swagger目前有两种swagger和swagger2两种,1比较麻烦,所以不考虑使用。本文主要记录我用swagger2做对外接口的两种方式,方面后面查阅。
使用传统的springmvc整合swagger2

spring-mvc.xml 中添加映射静态的配置
<!-- swagger静态文件路径 --> <mvc:resources location="classpath:/META-INF/resources/" mapping="swagger-ui.html"/> <mvc:resources location="classpath:/META-INF/resources/webjars/" mapping="/webjars/**"/>
swagger2的配置类:
@Configuration
@EnableSwagger2
public class SwaggerConfig extends WebMvcConfigurationSupport {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("net.laoyeyey.yyblog"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("yyblog项目 RESTful APIs")
.description("yyblog项目api接口文档")
.version("1.0")
.build();
}
}
paths如果在生产情况下可以调整为PathSelectors.none(),即不显示所有接口信息;
接口信息配置
即在SpringMvc的Controller中配置相关的接口信息
@Controller
@RequestMapping(value = "aitou")
@Api(description = "测试服务-账户信息查询")
public class DailyOperationDataController {
Logger logger = Logger.getLogger(DailyOperationDataController.class);
@Autowired
private DailyOperationDataService DailyOperationDataService;
/*
* @ApiOperation(value = "接口说明", httpMethod ="接口请求方式", response ="接口返回参数类型", notes ="接口发布说明"
* @ApiParam(required = "是否必须参数", name ="参数名称", value ="参数具体描述"
*/
@ApiOperation(value = "账户信息查询接口")
@RequestMapping(method ={RequestMethod.POST,RequestMethod.GET}, value="/query/dailydata/{dataDate}")
@ResponseBody
public DailyOperationDataDto getDailyReportByDataDate(@PathVariable("dataDate") String dataDate) {
try {
return DailyOperationDataService.getDailyReportByDataDate(dataDate);
} catch (Exception e) {
logger.error(e.getMessage(), e);
}
return null;
}
}
常用的一些注解
@Api:用在类上,说明该类的作用 @ApiOperation:用在方法上,说明方法的作用 @ApiImplicitParams:用在方法上包含一组参数说明 @ApiImplicitParam:用在 @ApiImplicitParams 注解中,指定一个请求参数的各个方面 paramType:参数放在哪个地方 · header --> 请求参数的获取:@RequestHeader · query -->请求参数的获取:@RequestParam · path(用于restful接口)--> 请求参数的获取:@PathVariable · body(不常用) · form(不常用) name:参数名 dataType:参数类型 required:参数是否必须传 value:参数的意思 defaultValue:参数的默认值 @ApiResponses:用于表示一组响应 @ApiResponse:用在@ApiResponses中,一般用于表达一个错误的响应信息 code:数字,例如400 message:信息,例如"请求参数没填好" response:抛出异常的类 @ApiParam:单个参数描述 @ApiModel:描述一个Model的信息,用对象来接收参数(这种一般用在post创建的时候,使用@RequestBody这样的场景,请求参数无法使用@ApiImplicitParam注解进行描述的时候) @ApiModelProperty:描述一个model的属性 @ApiProperty:用对象接收参数时,描述对象的一个字段 @ApiIgnore:使用该注解忽略这个API
使用springboot整合swagger2
maven依赖

添加静态资源配置
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {/**
* 配置静态资源路径以及上传文件的路径
*
* @param registry
*/
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
registry.addResourceHandler("/upload/**").addResourceLocations(environment.getProperty("spring.resources.static-locations"));
/*swagger-ui*/
registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
swagger2的配置类
@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Autowired
private BaseConfig baseConfig;
@Bean
public Docket createRestApi() {
if(Constant.TRUE.equals(baseConfig.getSwaggerShow())) {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.cpic.sxwx"))
.paths(PathSelectors.any())
.build();
}else {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.paths(PathSelectors.none())
.build();
}
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("springboot利用swagger构建api文档")
