swagger-ui 和 spring webflux 的 404 错误 [英] 404 error with swagger-ui and spring webflux
问题描述
我正在使用 Spring Webflux 开发 REST 服务,并且我想使用 Swagger2 为我的 API 生成文档.我发现只有 Swagger2 版本 3.0.0 快照支持 Webflux.
I am developping REST services with Spring Webflux and I want to produce documentation with Swagger2 for my API with. I discovered that Webflux is only supported with Swagger2 version 3.0.0 snapshot.
这是我的配置:
- Java 11
- Maven 3
我的 SwaggerConfiguration bean 看起来像这样
My SwaggerConfiguration bean looks like this
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2WebFlux;
@Configuration
@EnableSwagger2WebFlux
public class SwaggerConfig {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(new ApiInfoBuilder()
.description("My Reactive API")
.title("My Domain object API")
.version("1.0.0")
.build())
.enable(true)
.select()
.apis(RequestHandlerSelectors.basePackage("com.mypackage.service.myobject.controller"))
.paths(PathSelectors.any())
.build();
}
}
我的 springboot 应用定义如下:
My springboot app is defined like this :
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.reactive.config.EnableWebFlux;
@SpringBootApplication
@EnableWebFlux
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
这是我的 pom 配置
Here's my pom configuration
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.1.RELEASE</version>
</parent>
<properties>
<swagger.version>3.0.0-SNAPSHOT</swagger.version>
</properties>

但是,当我输入 http://localhost:8080/swagger-ui 时出现 404 错误.html 在我的浏览器中.如果我输入 http://localhost:8080/v2/api-docs,我会得到为我的 API 使用 json 格式的 swagger 文档.
However, I get a 404 error when I type http://localhost:8080/swagger-ui.html in my browser. If I type http://localhost:8080/v2/api-docs, I get the swagger document in json for my API.
我在 Intellij 下的调试中运行我的 springboot 应用程序.我尝试在命令行中运行 fat jar:同样的问题.有人知道我的配置有什么问题吗?
I run my springboot app in debug under Intellij. I try to run the fat jar in command line: same issue. Does somebody know what is wrong with my configuration?
谢谢
推荐答案
找到了!
我必须像这样为 swagger-ui 注册一个 webflux 资源处理程序.
I have to register a webflux resource handler for swagger-ui like this.
import org.springframework.context.annotation.Configuration;
import org.springframework.web.reactive.config.ResourceHandlerRegistry;
import org.springframework.web.reactive.config.WebFluxConfigurer;
@Configuration
public class WebfluxConfig implements WebFluxConfigurer {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/swagger-ui.html**")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
问题解决了!
