Linux Swagger与Spring Boot如何无缝对接

在Spring Boot项目中集成Swagger，可以方便地生成API文档，并提供在线测试功能。以下是实现Swagger与Spring Boot无缝对接的步骤：

1. 添加依赖

首先，在pom.xml文件中添加Swagger和Swagger UI的依赖：

<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>

2. 配置Swagger

创建一个配置类来配置Swagger。这个类需要使用@Configuration注解，并且需要启用Swagger2。

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.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.controller")) // 替换为你的控制器包路径
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("API Documentation")
                .description("API Documentation for Spring Boot Application")
                .version("1.0.0")
                .build();
    }
}

3. 启用Swagger

确保你的Spring Boot应用程序已经启用了Swagger。你可以在主应用程序类上添加@EnableSwagger2注解，或者在配置类中添加。

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@SpringBootApplication
@EnableSwagger2
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

4. 访问Swagger UI

启动你的Spring Boot应用程序后，你可以通过浏览器访问Swagger UI界面。默认情况下，Swagger UI的地址是：

http://localhost:8080/swagger-ui.html

5. 配置Swagger UI（可选）

你可以进一步自定义Swagger UI，例如添加认证、自定义主题等。以下是一个简单的示例，展示如何添加基本认证：

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.service.*;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spi.service.contexts.SecurityContext;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import java.util.Arrays;
import java.util.Collections;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.controller"))
                .paths(PathSelectors.any())
                .build()
                .securitySchemes(Arrays.asList(apiKey()))
                .securityContexts(Arrays.asList(securityContext()));
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("API Documentation")
                .description("API Documentation for Spring Boot Application")
                .version("1.0.0")
                .build();
    }

    private ApiKey apiKey() {
        return new ApiKey("JWT", "Authorization", "header");
    }

    private SecurityContext securityContext() {
        return SecurityContext.builder()
                .securityReferences(defaultAuth())
                .forPaths(PathSelectors.any())
                .build();
    }

    List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return Arrays.asList(new SecurityReference("JWT", authorizationScopes));
    }
}

通过以上步骤，你就可以在Spring Boot项目中无缝集成Swagger，并生成详细的API文档。
