使用 Spring Boot 配置 Swagger UI [英] Configuring Swagger UI with Spring Boot

问题描述

我正在尝试使用我的 Spring 启动应用程序配置 Swagger UI.尽管 v2/api-docs 似乎可以正确加载，但 http://localhost:8080/swagger-ui.html 并没有加载我带注释的 REST API.

I am trying to configure Swagger UI with my Spring boot application. Although the v2/api-docs seems to be loading properly, the http://localhost:8080/swagger-ui.html does not load my annotated REST API.

这是我所拥有的:

pom.xml:

...
<!--Swagger UI-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.6.1</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.4.0</version>
        </dependency>
...

SwaggerConfig.java

@Configuration

    @Bean
    public Docket api()
    {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(regex("/.*"))
                .build().apiInfo(apiInfo());
    }

    private ApiInfo apiInfo()
    {
        ApiInfo apiInfo = new ApiInfo(
                "My Project's REST API",
                "This is a description of your API.",
                "version-1",
                "API TOS",
                "[e-mail]",
                "API License",
                "API License URL"
        );
        return apiInfo;
    }
}

swagger-ui.html (http://localhost:8080/swagger-ui.html) 没有显示预期的 REST 调用:

The swagger-ui.html (http://localhost:8080/swagger-ui.html) does not show the expected REST calls:

代码检查中 swagger-ui.html 中的错误:加载资源失败:服务器响应状态为404().

The error in swagger-ui.html from the code inspection: Failed to load resource: the server responded with a status of 404 ().

我已经四处搜索(也尝试了 web-config mvc)，但错误仍然存​​在.也许我在 .iml 文件中缺少资源引用?

I have googled around (tried web-config mvc too) but the error persists. Maybe I am missing a resource reference in the .iml file?

推荐答案

我今天遇到了这个问题，并通过匹配我的 springfox-swagger2 和 springfox-swagger- 的版本来解决它ui 依赖:

I had this issue today and fixed it by matching up the versions of my springfox-swagger2 and springfox-swagger-ui dependencies:

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.6.1</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.6.1</version>
    </dependency>

几乎没有其他代码可以让它启动和运行.一个简单的配置类:

There's very little other code to just get it up and running. One simple config class:

@Configuration
@EnableSwagger2
class SwaggerConfiguration {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.foo.samples.swaggersample"))
                .paths(PathSelectors.any())
                .build();
    }

}

还有我的 application.properties

And my application.properties

# location of the swagger json
springfox.documentation.swagger.v2.path=/swagger.json

(这是在 Spring Boot 中).
