swagger与springCloudGateway整合
单个服务swagger配置
增加依赖
<!-- swagger -->
<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>
增加swagger配置文件
@Configuration
@EnableSwagger2
public class SwaggerConfig{
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2) //主要api配置机制初始化为swagger规范2.0
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("换成你的controller包名"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("Spring Boot中使用Swagger2构建RESTful API") // 标题
.description("测试") // 描述信息
.termsOfServiceUrl("服务地址") //服务网址
.version("1.0") //版本号
.build();
}
}
解决静态资源无法访问的问题
@Configuration
public class CorsConfig extends WebMvcConfigurationSupport{
/**
* 解决swagger-ui.html 404无法访问的问题
*/
@Override
protected void addResourceHandlers(ResourceHandlerRegistry registry) {
// 解决静态资源无法访问
registry.addResourceHandler("/**")
.addResourceLocations("classpath:/static/");
// 解决swagger无法访问
registry.addResourceHandler("/swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");
// 解决swagger的js文件无法访问
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowedMethods("PUT", "DELETE", "GET", "POST", "OPTIONS")
.allowCredentials(true).maxAge(3600);
}
}
接口参数说明
@ApiOperation(value = "测试swagger")
@ApiImplicitParams({
@ApiImplicitParam(name = "deviceId",value = "设备ID",dataType = "string",paramType = "query",required = true),
@ApiImplicitParam(name = "wifiId",value = "wifiID",dataType = "string",paramType = "query",required = true),
@ApiImplicitParam(name = "token",value = "token",dataType = "string",paramType = "query",required = true)
})
@ApiResponses({@ApiResponse(code = 200,message = "OK",response = ResponseData.class)})

<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>

swagger配置
共需增加三个配置文件
SwaggerProvider
@Component
@Primary
@AllArgsConstructor
public class GwSwaggerResourceProvider implements SwaggerResourcesProvider {
public static final String API_URI = "/v2/api-docs";
private final RouteLocator routeLocator;
private final GatewayProperties gatewayProperties;
@Override
public List<SwaggerResource> get() {
List<SwaggerResource> resources = new ArrayList<>();
List<String> routes = new ArrayList<>();
routeLocator.getRoutes().subscribe(route -> routes.add(route.getId()));
gatewayProperties.getRoutes().stream().filter(routeDefinition -> routes.contains(routeDefinition.getId()))
.forEach(routeDefinition -> routeDefinition.getPredicates().stream()
.filter(predicateDefinition -> ("Path").equalsIgnoreCase(predicateDefinition.getName()))
.forEach(predicateDefinition -> resources.add(swaggerResource(routeDefinition.getId(),
predicateDefinition.getArgs().get(NameUtils.GENERATED_NAME_PREFIX + "0")
.replace("/**", API_URI)))));
return resources;
}
private SwaggerResource swaggerResource(String name, String location) {
SwaggerResource swaggerResource = new SwaggerResource();
swaggerResource.setName(name);
swaggerResource.setLocation(location);
swaggerResource.setSwaggerVersion("2.0");
return swaggerResource;
}
}
SwaggerHandler
@RestController
@RequestMapping("/swagger-resources")
public class SwaggerHandler {
@Autowired(required = false)
private SecurityConfiguration securityConfiguration;
@Autowired(required = false)
private UiConfiguration uiConfiguration;
private final SwaggerResourcesProvider swaggerResources;
@Autowired
public SwaggerHandler(SwaggerResourcesProvider swaggerResources) {
this.swaggerResources = swaggerResources;
}
@GetMapping("/configuration/security")
public Mono<ResponseEntity<SecurityConfiguration>> securityConfiguration() {
return Mono.just(new ResponseEntity<>(
Optional.ofNullable(securityConfiguration).orElse(SecurityConfigurationBuilder.builder().build()), HttpStatus.OK));
}
@GetMapping("/configuration/ui")
public Mono<ResponseEntity<UiConfiguration>> uiConfiguration() {
return Mono.just(new ResponseEntity<>(
Optional.ofNullable(uiConfiguration).orElse(UiConfigurationBuilder.builder().build()), HttpStatus.OK));
}
@GetMapping("")
public Mono<ResponseEntity> swaggerResources() {
return Mono.just((new ResponseEntity<>(swaggerResources.get(), HttpStatus.OK)));
}
}
SwaggerHeaderFilter
@Component
public class SwaggerHeaderFilter extends AbstractGatewayFilterFactory {
private static final String HEADER_NAME = "X-Forwarded-Prefix";
@Override
public GatewayFilter apply(Object config) {
return (exchange, chain) -> {
ServerHttpRequest request = exchange.getRequest();
String path = request.getURI().getPath();
if (!StringUtils.endsWithIgnoreCase(path, SwaggerProvider.API_URI)) {
return chain.filter(exchange);
}
String basePath = path.substring(0, path.lastIndexOf(SwaggerProvider.API_URI));
ServerHttpRequest newRequest = request.mutate().header(HEADER_NAME, basePath).build();
ServerWebExchange newExchange = exchange.mutate().request(newRequest).build();
return chain.filter(newExchange);
};
}
}
增加配置
#默认所有服务转发操作
spring.cloud.gateway.discovery.locator.enabled=true
#小写服务名
spring.cloud.gateway.discovery.locator.lower-case-service-id=true
#path路由断言
spring.cloud.gateway.routes[0].id=springcloud-test
spring.cloud.gateway.routes[0].uri=lb://springcloud-test
spring.cloud.gateway.routes[0].predicates[0]=Path=/springcloud-test/**
spring.cloud.gateway.routes[0].filters[0].name=SwaggerHeaderFilter
spring.cloud.gateway.routes[1].id=springcloud-test2
spring.cloud.gateway.routes[1].uri=lb://springcloud-test2
spring.cloud.gateway.routes[1].predicates[0]=Path=/springcloud-test2/**
spring.cloud.gateway.routes[1].filters[0].name=SwaggerHeaderFilter
实现效果
注意
如配置了全局过滤，需增加白名单
