1. pom 文件 在 maven 仓库中输入 springfox查到最新的

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

2.配置
主要映射 视图
不然访问不了
访问地址
localhost:9000/swagger-ui.html

@Configuration
public class WebMVCConfig extends WebMvcConfigurerAdapter {
    /**
     * 配置swagger 映射路径
     * @param registry
     */
    @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/");
    }
}

开启，填写相关信息

@Configuration
@EnableWebMvc
@EnableSwagger2
@ComponentScan(basePackages = { "cn.lucode.*" })
public class SwaggerConfig {
    ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("lucode Web SelfService APIs")
                .description("")
                .license("")
                .licenseUrl("")
                .termsOfServiceUrl("")
                .version("1.0.0")
                .build();
    }
    @Bean
    public Docket customImplementation() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("cn.lucode"))
                .build()
                .directModelSubstitute(org.joda.time.LocalDate.class, java.sql.Date.class)
                .directModelSubstitute(org.joda.time.DateTime.class, java.util.Date.class)
                .apiInfo(apiInfo());
    }
}
