1.加入依賴

  compile group: 'io.springfox', name: 'springfox-boot-starter', version: '3.0.0'

2.swagger配置類

  @Configuration
public class SwaggerConfiguration implements WebMvcConfigurer {
    private static final String API_BASE_PACKAGE = "com.romens.market.webapp";
    @Autowired
    private SwaggerConfigProperties configProperties;

    @Bean
    public Docket createRestApi() {
        Docket docket = new Docket(DocumentationType.OAS_30)
                // 定義是否開啟swagger，false為關(guān)閉，可以通過變量控制
                .enable(configProperties.isEnable())
                .pathMapping("/")
                .select()
                .apis(RequestHandlerSelectors.basePackage(API_BASE_PACKAGE))
                .paths(PathSelectors.any())
                .build()
                .globalRequestParameters(getGlobalRequestParameters())
                .directModelSubstitute(org.joda.time.LocalDate.class, java.sql.Date.class)
                .directModelSubstitute(org.joda.time.DateTime.class, java.util.Date.class);
        if (!StringUtils.isEmpty(configProperties.getPrefix())) {
            docket.pathMapping(configProperties.getPrefix());
        }
        return docket.apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {
        Contact contact = new Contact("項目組",
                "http://www./",
                "xx@xx.cn");
        return new ApiInfoBuilder()
                .title("webapp-service")
                .description("模塊")
                .termsOfServiceUrl("")
                .contact(contact)
                .version("1.0.0")
                .build();
    }

    /**
     * 通用攔截器排除swagger設(shè)置呵恢，所有攔截器都會自動加swagger相關(guān)的資源排除信息
     */
    @SuppressWarnings("unchecked")
    @Override
    public void addInterceptors(InterceptorRegistry registry) {

        try {
            Field registrationsField = FieldUtils.getField(InterceptorRegistry.class, "registrations", true);
            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) {
            e.printStackTrace();
        }
    }

    //生成全局通用參數(shù)
    private List<RequestParameter> getGlobalRequestParameters() {
        List<RequestParameter> parameters = new ArrayList<>();
        parameters.add(new RequestParameterBuilder()
                .name("entId")
                .description("企業(yè)號")
                .required(true)
                .in(ParameterType.HEADER)
                .query(q -> q.model(m -> m.scalarModel(ScalarType.STRING)))
                .required(false)
                .build());
        parameters.add(new RequestParameterBuilder()
                .name("operator")
                .description("操作人")
                .required(false)
                .in(ParameterType.HEADER)
                .query(q -> q.model(m -> m.scalarModel(ScalarType.STRING)))
                .required(false)
                .build());
        return parameters;
    }

    //生成通用響應(yīng)信息
    private List<Response> getGlobalResonseMessage() {
        List<Response> responseList = new ArrayList<>();
        responseList.add(new ResponseBuilder().code("404").description("找不到資源").build());
        return responseList;
    }

}

3.添加資源映射（重要）

  @Configuration
public class RomensWebMvcConfigurationSupport extends WebMvcConfigurationSupport {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("doc.html")
                .addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/swagger-ui/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/springfox-swagger-ui/");
        registry.addResourceHandler("favicon.ico")
                .addResourceLocations("classpath:/static/favicon.ico");
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
    

補充
1）swagger增強(qiáng)
