Swagger2在spring拦截器的配置及全局参数设置

一：配置拦截器

默认拦截器是对Swagger2请求时拦截的。

@Configuration
@EnableWebMvc
public class MvcConfig implements WebMvcConfigurer {



    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        //配置登录拦截器
        registry.addInterceptor(new AuthorizedCheckInterceptor()).
                addPathPatterns("/**")
                    .excludePathPatterns("/users/login/**", "/swagger-resources/**", "/webjars/**", "/swagger-ui.html/**");
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        //将templates目录下的CSS、JS文件映射为静态资源，防止Spring把这些资源识别成thymeleaf模版
        //  registry.addResourceHandler("/templates/**.js").addResourceLocations("classpath:/templates/");
        //registry.addResourceHandler("/templates/**.css").addResourceLocations("classpath:/templates/");
        //其他静态资源
        //registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
        //swagger增加url映射
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }

}

二 配置全局参数

如配置所有请求header中需要添加token，配置全局响应码

package org.niugang.coding.conf;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.RequestMethod;
import springfox.documentation.builders.*;
import springfox.documentation.schema.ModelRef;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.service.Parameter;
import springfox.documentation.service.ResponseMessage;
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 {

    /**
     * 全局参数(如header中的token)
     *
     * @return List<Parameter>
     */
    private List<Parameter> parameter() {
        List<Parameter> params = new ArrayList<>();
        params.add(new ParameterBuilder().name("token")
                .description("请求令牌")
                .modelRef(new ModelRef("string"))
                .parameterType("header")
                .required(false).build());
        return params;
    }

    @Bean
    public Docket sysApi() {
        //设置全局响应状态码
        List<ResponseMessage> responseMessageList = new ArrayList<>();
        responseMessageList.add(new ResponseMessageBuilder().code(404).message("找不到资源").responseModel(new ModelRef("ApiError")).build());
        responseMessageList.add(new ResponseMessageBuilder().code(400).message("参数错误").responseModel(new ModelRef("ApiError")).build());
        responseMessageList.add(new ResponseMessageBuilder().code(401).message("没有认证").responseModel(new ModelRef("ApiError")).build());
        responseMessageList.add(new ResponseMessageBuilder().code(500).message("服务器内部错误").responseModel(new ModelRef("ApiError")).build());
        responseMessageList.add(new ResponseMessageBuilder().code(403).message("没有没有访问权限").responseModel(new ModelRef("ApiError")).build());
        responseMessageList.add(new ResponseMessageBuilder().code(200).message("请求成功").responseModel(new ModelRef("ApiError")).build());

        return new Docket(DocumentationType.SWAGGER_2)
                .globalResponseMessage(RequestMethod.GET, responseMessageList)
                .globalResponseMessage(RequestMethod.POST, responseMessageList)
                .globalResponseMessage(RequestMethod.PUT, responseMessageList)
                .globalResponseMessage(RequestMethod.DELETE, responseMessageList)
                .apiInfo(apiInfo())
                .select()
                 //默认显示所有controller
                .apis(RequestHandlerSelectors.basePackage("org.niugang.coding"))
                .paths(PathSelectors.any())
                .build().globalOperationParameters(parameter());
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("new-coding-standards-user")
                .description("springboot新代码规范脚手架工程")
                .termsOfServiceUrl("")
                .contact(new Contact("niugang", "", "863263957@qq.com"))
                .version("1.0")
                .build();
    }
