springboot引入swagger2

1，pom文件里引入swagger-ui依赖

bash 复制代码

    <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.7.0</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.7.0</version>
        </dependency>

2，在config里添加swagger基础配置

bash 复制代码

public abstract class BaseSwaggerConfig {

    @Bean
    public Docket createRestApi() {
        SwaggerProperties swaggerProperties = swaggerProperties();
        Docket docket = new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo(swaggerProperties))
                .directModelSubstitute(Byte.class, Integer.class)
                .select()
                .apis(RequestHandlerSelectors.basePackage(swaggerProperties.getApiBasePackage()))
                .paths(PathSelectors.any())
                .build();
        if (swaggerProperties.isEnableSecurity()) {
            docket.securitySchemes(securitySchemes()).securityContexts(securityContexts());
        }
        return docket;
    }

    private ApiInfo apiInfo(SwaggerProperties swaggerProperties) {
        return new ApiInfoBuilder()
                .title(swaggerProperties.getTitle())
                .description(swaggerProperties.getDescription())
                .contact(new Contact(swaggerProperties.getContactName(), swaggerProperties.getContactUrl(), swaggerProperties.getContactEmail()))
                .version(swaggerProperties.getVersion())
                .build();
    }

    private List<ApiKey> securitySchemes() {
        //设置请求头信息
        List<ApiKey> result = new ArrayList<>();
        ApiKey apiKey = new ApiKey("Authorization", "Authorization", "header");
        result.add(apiKey);
        return result;
    }

    private List<SecurityContext> securityContexts() {
        //设置需要登录认证的路径
        List<SecurityContext> result = new ArrayList<>();
        result.add(getContextByPath("/*/.*"));
        return result;
    }

    private SecurityContext getContextByPath(String pathRegex) {
        return SecurityContext.builder()
                .securityReferences(defaultAuth())
                .forPaths(PathSelectors.regex(pathRegex))
                .build();
    }

    private List<SecurityReference> defaultAuth() {
        List<SecurityReference> result = new ArrayList<>();
        AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        result.add(new SecurityReference("Authorization", authorizationScopes));
        return result;
    }

    /**
     * 自定义Swagger配置
     */
    public abstract SwaggerProperties swaggerProperties();
}

3，config里添加swagger自定义配置

bash 复制代码

@Data
@EqualsAndHashCode(callSuper = false)
@Builder
public class SwaggerProperties {
    /**
     * API文档生成基础路径
     */
    private String apiBasePackage;
    /**
     * 是否要启用登录认证
     */
    private boolean enableSecurity;
    /**
     * 文档标题
     */
    private String title;
    /**
     * 文档描述
     */
    private String description;
    /**
     * 文档版本
     */
    private String version;
    /**
     * 文档联系人姓名
     */
    private String contactName;
    /**
     * 文档联系人网址
     */
    private String contactUrl;
    /**
     * 文档联系人邮箱
     */
    private String contactEmail;
}

4，API文档相关配置

bash 复制代码

@Configuration
@EnableSwagger2
public class SwaggerConfig extends BaseSwaggerConfig{

    @Override
    public SwaggerProperties swaggerProperties() {
        return SwaggerProperties.builder()
                .apiBasePackage("com.linz.app")
                .title("Maven测试")
                .description("Maven测试相关接口文档")
                .contactName("test")
                .version("1.0")
                .enableSecurity(true)
                .build();
    }
}
