SwaggerAPI配置

每个需要提供API的都需要配置（User-Service / Schedule-Service / Auth-service）

/**
 * AuthServerConfig
 * 

 * Description:
 * 

 * Creation Time: 2019/3/12 22:39.
 *
 * @author HuWeihui
 */
@Configuration
@EnableSwagger2
public class SwaggerConfig {
     

    @Bean
    public Docket createRestApi() {
     
        // 构建授权参数在请求头
        ParameterBuilder parBuilder = new ParameterBuilder();
        List<Parameter> pars = new ArrayList<Parameter>();
        Parameter authorizationParameter =
                parBuilder.name("Authorization")
                        .description("授权TOKEN")
                        .modelRef(new ModelRef("string"))
                        .parameterType("header").required(false).build();
        pars.add(authorizationParameter);

        StopWatch watch = new StopWatch();
        watch.start();
        Docket swaggerSpringMvcPlugin = new Docket(DocumentationType.SWAGGER_2)
                .groupName("usercenter-service")
                .apiInfo(apiInfo())
                .globalOperationParameters(pars)
                .useDefaultResponseMessages(false)
                .select().apis(RequestHandlerSelectors.basePackage("com.hui.cloud.uc"))
                .paths(PathSelectors.any())
                .build();
        watch.stop();
        return swaggerSpringMvcPlugin;
    }

    private ApiInfo apiInfo() {
     
        String title = "usercenter-service API文档";
        String description = " RESTFUL API";
        return new ApiInfoBuilder()
                .title(title)
                .description(description)
                .version("1.0.0")
                .build();
    }

}

Gateway新增SwaggerAPI聚合配置

/**
 * SwaggerProvider
 * 

 * Description
 * 

 * Creation Time: 2019/9/13 0:44.
 *
 * @author Hu-Weihui
 */
@Component
@Primary
@AllArgsConstructor
public class SwaggerProvider implements SwaggerResourcesProvider {
     
    public static final String API_URI = "/v2/api-docs";

    @Autowired
    private final RouteLocator routeLocator;

    @Autowired
    private final GatewayProperties gatewayProperties;

    @Override
    public List<SwaggerResource> get() {
     
        List<SwaggerResource> resources = new ArrayList<>();
        List<String> routes = new ArrayList<>();
        //取出gateway的route
        routeLocator.getRoutes().subscribe(route -> routes.add(route.getId()));
        //结合配置的route-路径(Path)，和route过滤，只获取有效的route节点
        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")
                                        // 注意我的swagger配置了 group 所以传参新增 ?group=serviceId
                                        .replace("/**", API_URI+"?group="+routeDefinition.getId())))));
        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;
    }
}

Gateway对外提供Swagger资源

/**
 * SwaggerHandler
 * 
 * 描述：
 * 
 * Creation Time: 2019/10/4 18:13.
 *
 * @author Gary.Hu
 */
@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)));
    }
}

如果配置了Oauth2认证授权，需要开放Swagger的资源

/**
 * ResourceServerConfig
 * 
 * 描述：资源服务配置
 * 
 * Creation Time: 2019/10/1 1:38.
 *
 * @author Gary.Hu
 */
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
     

    private TokenStore tokenStore;

    @Autowired
    public ResourceServerConfig(TokenStore tokenStore) {
     
        this.tokenStore = tokenStore;
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
     
        http
                .csrf().disable()
                .authorizeRequests()
                //swagger放行
                .antMatchers("/swagger-ui.html", "/swagger-resources/**", "/webjars/**", "/v2/**").permitAll()
                .antMatchers("/usercenter-service/**").permitAll()
                //允许登录、注册放行
                .antMatchers("/sys-user/user","/sys-user/login","/sys-user/register","/h2-console").permitAll()
                // 健康检查放行
                .antMatchers("/actuator/**").permitAll()
                //OPTIONS请求 放行
                .antMatchers(HttpMethod.OPTIONS).permitAll()
                .anyRequest().authenticated();

    }

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
     
        resources
                .tokenStore(tokenStore)
                // 设置资源ID
                .resourceId("usercenter-service");
    }
}
