Я загрузил простое приложение Spring Boot и добавил Swagger.Это работало просто отлично.
Затем я добавил поддержку OAuth в свое приложение, и Swagger UI выдает ошибку, каждый раз, когда я захожу на http://localhost:8080/swagger-ui.html, я получаю сообщение об ошибке:
Не удалось загрузить определение API.
Ошибки
Ошибка выборки не определена http://localhost:8080/v2/api-docs
Как показано на рисунке ниже: 
В инструментах разработчика браузера я вижу запрос GET с кодом ответа 500 и двумя кодами ответа 404, как показано ниже: 
Поскольку я Reactive Netty (из Spring WebFlux) не поддерживает OAuth2, я изменил свой сервер приложений на использование Tomcat вместо Reactive Netty, как показано ниже:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
<exclusions>
<!-- Exclude Reactor Netty because for now we need the servlet classes -->
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-reactor-netty</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- For now we are using Tomcat server and not Netty (excluded above) -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
<!-- We still want to use the Reactive features that come with project reactor-netty (like WebClient) -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-reactor-netty</artifactId>
</dependency>
Мой OAuth2SecurityConfiguration класс, который расширяет WebSecurityConfigurerAdapter, конфигурируетHttpSecurity as
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.cors().disable()
.csrf().disable()
.authorizeRequests()
.antMatchers("/oauth/token").permitAll();
}
Тогда мой сервер ресурсов установлен как:
@Configuration
@EnableResourceServer
public class ResourceServer extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http
.cors().disable()
.csrf().disable()
.headers().frameOptions().disable()
.and()
.authorizeRequests()
.antMatchers("/actuator/**").hasRole("ADMIN") // Spring Actuator endpoints
.antMatchers("/user/**").hasRole("USER") // App REST endpoints
.anyRequest().permitAll();
}
}
Таким образом, все запросы к Swagger не должны проходить аутентификацию

ПопробоватьЯ добавил веб-зависимость Spring Boot, но происходит то же исключение.
Я не нахожу ссылки на ServerHttpRequest в своем коде, поэтому она должна быть вызвана некоторой зависимостью (я очень подозреваю OAuth и SpringЗависимости безопасности, поскольку они являются единственными новыми зависимостями с тех пор, как Swagger работал в последний раз, просто отлично).
Вот моя конфигурация Swagger
@Configuration
@EnableSwagger2WebFlux
public class SwaggerConfig {
@Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
// Make only our app specific endpoints available in Swagger docs
.apis(RequestHandlerSelectors.basePackage("com.xxxxx.spring.poc"))
.build()
.apiInfo(apiInfo());
}
private ApiInfo apiInfo() {
return new ApiInfo("Simple Spring PoC",
"A very simple CRUD application developed with Spring Boot 2",
"0.1",
"Terms of service",
new Contact("XXXXX", "www.xxxxxx.com", "xxxxx@xxxxx.com"),
"License of API", "https://www.apache.org/licenses/LICENSE-2.0", Collections.emptyList());
}
}
Итак, мой вопрос, почему и как я могу это исправитьОшибка Swagger и показать мою документацию REST?
