1.pom中添加swagger依赖

<!-- swagger-ui -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.8.0</version>
            <exclusions>
                <exclusion>
                    <artifactId>javassist</artifactId>
                    <groupId>org.javassist</groupId>
                </exclusion>
            </exclusions>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.8.0</version>
            <exclusions>
                <exclusion>
                    <artifactId>javassist</artifactId>
                    <groupId>org.javassist</groupId>
                </exclusion>
            </exclusions>
        </dependency>

2.编写配置类

@Configuration
@EnableSwagger2
public class SwaggerConfiguration {

    @Bean
    public Docket createRestApi() {
        System.out.println("======  SWAGGER CONFIG  ======");
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo()).select()
                .apis(RequestHandlerSelectors.basePackage("controller包的全路径名"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("xxxx RESTful APIs")
                .description("快速上手,快速开发,快速交接")
                .contact("xxxx")
                .version("2.0.0")
                .build();
    }

}

3.添加静态资源访问及权限拦截的放行(可选)

/**
 * application configuration
 */
@Configuration
public class AppConfiguration implements WebMvcConfigurer {

  public static final String LOGIN_INTERCEPTOR_PATH_PATTERN = "/**/*";
  public static final String LOGIN_PATH_PATTERN = "/login";
  public static final String PATH_PATTERN = "/**";
  public static final String LOCALE_LANGUAGE_COOKIE = "language";
  public static final int COOKIE_MAX_AGE = 3600;

  @Bean
  public LoginHandlerInterceptor loginInterceptor() {
    return new LoginHandlerInterceptor();
  }

  /**
   * Cookie
   * @return local resolver
   */
  @Bean(name = "localeResolver")
  public LocaleResolver localeResolver() {
    CookieLocaleResolver localeResolver = new CookieLocaleResolver();
    localeResolver.setCookieName(LOCALE_LANGUAGE_COOKIE);
    /** set default locale **/
    localeResolver.setDefaultLocale(Locale.US);
    /** set cookie max age **/
    localeResolver.setCookieMaxAge(COOKIE_MAX_AGE);
    return localeResolver;
  }

  @Bean
  public LocaleChangeInterceptor localeChangeInterceptor() {
    LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
    /**  **/
    lci.setParamName("language");

    return lci;
  }

  @Override
  public void addInterceptors(InterceptorRegistry registry) {
    //i18n
    registry.addInterceptor(localeChangeInterceptor());

    registry.addInterceptor(loginInterceptor())
            .addPathPatterns(LOGIN_INTERCEPTOR_PATH_PATTERN)
            .excludePathPatterns(LOGIN_PATH_PATTERN,"/swagger-ui.html","/swagger-resources/**", "/webjars/**", "/v2/**", "/doc.html", "*.html", "/ui/**");
  }

  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
    registry.addResourceHandler("doc.html").addResourceLocations("classpath:/META-INF/resources/");
    registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    registry.addResourceHandler("/ui/**").addResourceLocations("file:ui/");
    // 解决swagger无法访问
    registry.addResourceHandler("/swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
  }

  @Override
  public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/ui/").setViewName("forward:/ui/index.html");
    registry.addViewController("/").setViewName("forward:/ui/index.html");
  }

  @Override
  public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping(PATH_PATTERN).allowedOrigins("*").allowedMethods("*");
  }

  /**
   * Turn off suffix-based content negotiation
   *
   * @param configurer configurer
   */
  @Override
  public void configureContentNegotiation(final ContentNegotiationConfigurer configurer) {
    configurer.favorPathExtension(false);
  }

}
