一、整合swagger2

1、添加依赖

implementation 'io.springfox:springfox-swagger2:2.9.2'
    	implementation 'com.github.xiaoymin:swagger-bootstrap-ui:1.8.9'

2、写配置文件SwaggerConfig

import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import springfox.documentation.builders.ApiInfoBuilder;
    import springfox.documentation.builders.ParameterBuilder;
    import springfox.documentation.builders.PathSelectors;
    import springfox.documentation.builders.RequestHandlerSelectors;
    import springfox.documentation.schema.ModelRef;
    import springfox.documentation.service.ApiInfo;
    import springfox.documentation.service.Contact;
    import springfox.documentation.service.Parameter;
    import springfox.documentation.spi.DocumentationType;
    import springfox.documentation.spring.web.plugins.Docket;
    import springfox.documentation.swagger2.annotations.EnableSwagger2;
    
    import java.util.ArrayList;
    import java.util.List;
    
    @Configuration
    @EnableSwagger2
    public class SwaggerConfig {
    
        @Bean
        public Docket createRESTApi() {
            //请求时添加head参数start
            ParameterBuilder tokenPar = new ParameterBuilder();
            List<Parameter> pars = new ArrayList<Parameter>();
            tokenPar.name("token").description("令牌").modelRef(new ModelRef("string")).parameterType("header").required(false).build();
            pars.add(tokenPar.build());
            return new Docket(DocumentationType.SWAGGER_2)
                    .apiInfo(apiInfo()).select()
                    .apis(RequestHandlerSelectors.basePackage("com.zz.www"))
                    .paths(PathSelectors.any())
                    .build()
                    .globalOperationParameters(pars);
        }
    
        private ApiInfo apiInfo() {
            Contact contact = new Contact("zz", "", "729253864.@qq.com");
            return new ApiInfoBuilder()
                    .title("测试")
                    .description("测试系统API后台服务接口")
                    .termsOfServiceUrl("http://www.baidu.com")
                    .contact(contact)
                    .version("1.0")
                    .build();
        }
    
    }

**注意：**.apis(RequestHandlerSelectors.basePackage("com.zz.www"))里面的com.zz.www改成自己的包名

3、访问，IP+端口+doc.html,效果如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk5NjYzMg_size_16_color_FFFFFF_t_70][]

更换swagger-ui

implementation 'io.springfox:springfox-swagger2:2.9.2'
    	implementation 'io.springfox:springfox-swagger-ui:2.9.2'

访问：IP+端口+swagger-ui.html,效果如下，controller层加上swwager注解，将会在页面具体显示

代码

@Api(description = "用户登录")
    @RestController
    public class UserLoginController {
    
        @ApiOperation(value = "登录", notes="登录啊")
        @PostMapping("login")
        private String login(String account, String password, HttpServletResponse response) {
            return null;
        }
    
        @ApiOperation(value = "登出", notes="登出啊")
        @GetMapping("logout")
        private String logout() {
            return null;
        }
    
    }

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk5NjYzMg_size_16_color_FFFFFF_t_70 1][]

不添加注解时如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTk5NjYzMg_size_16_color_FFFFFF_t_70 2][]

注：当项目有拦截器时，需要取消对swagger-ui的访问验证，否则将访问失败

shiro: ShiroConfig中取消验证：

filterMap.put("/swagger-ui.html", "anon");
            filterMap.put("/v2/api-docs", "anon");
            filterMap.put("/webjars/**", "anon");
            filterMap.put("/swagger-resources/**", "anon");

拦截器： 拦截器取消验证

     */
    @Controller
    public class UserTokenInterceptor implements HandlerInterceptor{
    
        @Autowired
        private TRUserService trUserService;
    
        @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
            HttpSession session = request.getSession();
            TRUser user = (TRUser) session.getAttribute("user");
            if (BeanUtil.isEmpty(user)) {

                result.setError("登录超时", -1);
                returnResult(result, response);
                return false;
            } else {
                Result result = new Result();
                String username = user.getUsername();

                        return false;

            return true;
        }
    
        private void returnResult(Result result, HttpServletResponse response) {
            PrintWriter writer = null;
            response.setCharacterEncoding("UTF-8");
            response.setContentType("application/json;charset=UTF-8");
            String json = JSON.toJSONString(result);
            try {
                writer = response.getWriter();
                writer.print(json);
            } catch (Exception e) {
    
            } finally {
                if (null != writer) {
                    writer.close();
                }
            }
        }
    }

    @Component
    public class WebMvcConfig extends WebMvcConfigurationSupport{
    
        @Autowired
        private UserTokenInterceptor userTokenInterceptor;
    
        @Override
        protected void addResourceHandlers(ResourceHandlerRegistry registry) {
            registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");
            registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
            registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
        }
    
        @Override
        protected void addInterceptors(InterceptorRegistry registry) {
            registry.addInterceptor(userTokenInterceptor)
                    .addPathPatterns("/**")
                    .excludePathPatterns(
                            "/","/static/**",// 静态资源
                            "/swagger-ui.html","/v2/api-docs","/webjars/**","/swagger-resources/**", // SwaggerUI
                            "/login" // 用户登录
                    );
        }
    }

二、整合swagger3

1、添加依赖

implementation 'io.springfox:springfox-boot-starter:3.0.0'

2、配置文件application.yml添加

application:
      name: lzz
      version: 0.0.1
      description: 描述

3、添加swagger配置文件，此处已经过滤掉拦截器，后面配置将不必再次配置(遗留问题：项目版本号手动配置，非自动获取以及添加拦截之后页面无法访问)

    import org.springframework.boot.SpringBootVersion;
    import org.springframework.context.annotation.Bean;

    @Configuration
    @EnableOpenApi
    public class SwaggerConfig implements WebMvcConfigurer {
    
        @Value("${swagger2.enable}")
        private boolean enable;
    
        @Value("${application.name}")
        private String applicationName;
    
        @Value("${application.version}")
        private String applicationVersion;

        public Docket createRestApi()
        {
            return new Docket(DocumentationType.OAS_30).pathMapping("/")
    
                    // 定义是否开启swagger，false为关闭，可以通过变量控制
                    .enable(enable)
    
                    // 将api的元信息设置为包含在json ResourceListing响应中。
                    .apiInfo(apiInfo())
    
                    // 选择哪些接口作为swagger的doc发布
                    .select()
                    .apis(RequestHandlerSelectors.any())
                    .paths(PathSelectors.any())
                    .build()
    
                    // 支持的通讯协议集合
                    .protocols(newHashSet("https", "http"))
    
                    // 授权信息设置，必要的header token等认证信息
                    .securitySchemes(securitySchemes())
    
                    // 授权信息全局应用
                    .securityContexts(securityContexts());
        }
    
        /**
         * API 页面上半部分展示信息
         */
        private ApiInfo apiInfo()
        {
            return new ApiInfoBuilder().title("Sinhy " + applicationName + " Api Doc")
                    .description(applicationDescription)
                    .contact(new Contact("JetLi", null, "zhangz@163.com"))
                    .version("Application Version: " + applicationVersion + ", Spring Boot Version: " + SpringBootVersion.getVersion())
                    .build();
        }
    
        /**
         * 设置授权信息
         */
        private List<SecurityScheme> securitySchemes()
        {
            return Collections.singletonList(new ApiKey("BASE_TOKEN", "token", "pass"));
        }
    
        /**
         * 授权信息全局应用
         */
        private List<SecurityContext> securityContexts()
        {
            return Collections.singletonList(
                    SecurityContext.builder().securityReferences(Collections.singletonList(new SecurityReference("BASE_TOKEN", new AuthorizationScope[] {new AuthorizationScope("global", "")}))).build());
        }
    
        @SafeVarargs
        private final <T> Set<T> newHashSet(T... ts)
        {
            if (ts.length > 0)
            {
                return new LinkedHashSet<>(Arrays.asList(ts));
            }
            return null;
        }
    
        /**
         * 通用拦截器排除swagger设置，所有拦截器都会自动加swagger相关的资源排除信息
         */
        @SuppressWarnings("unchecked")
        public void addInterceptors(InterceptorRegistry registry)
        {
            try
            {
                Field registrationsField = ReflectionUtils.findField(InterceptorRegistry.class, "registrations");
                List<InterceptorRegistration> registrations = (List<InterceptorRegistration>) ReflectionUtils.getField(registrationsField, registry);
                if (registrations != null)
                {
                    for (InterceptorRegistration interceptorRegistration : registrations)
                    {
                        interceptorRegistration
                                .excludePathPatterns("/swagger**/**")
                                .excludePathPatterns("/webjars/**")
                                .excludePathPatterns("/v3/**")
                                .excludePathPatterns("/doc.html");
                    }
                }
            }
            catch (Exception e)
            {
    
            }
        }
    }

4、访问IP+端口://swagger-ui/index.html   注意此处与swagger2的访问路径不同，效果如下

swagger3的Authorize可全局设置，见下图
