package com.example.emos.wx.config;

import io.swagger.annotations.ApiOperation;
import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.ApiKey;
import springfox.documentation.service.AuthorizationScope;
import springfox.documentation.service.SecurityReference;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spi.service.contexts.SecurityContext;
import springfox.documentation.spring.web.plugins.ApiSelectorBuilder;
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(){
        Docket docket=new Docket(DocumentationType.SWAGGER_2);
        //配置Docket基本信息
        ApiInfoBuilder builder=new ApiInfoBuilder();
        builder.title("EMOS在线办公");
        ApiInfo info=builder.build();
        docket.apiInfo(info);

        //哪些类的哪些方法要添加到swagger里面
        ApiSelectorBuilder selectorBuilder=docket.select();
        selectorBuilder.paths(PathSelectors.any());
        selectorBuilder.apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class));
        selectorBuilder.build();
        ApiKey apikey=new ApiKey("token","token","header");

        List<ApiKey> list=new ArrayList<>();
        list.add(apikey);
        docket.securitySchemes(list);
        //设定令牌作用域
        AuthorizationScope scope=new AuthorizationScope("global","accessEverything");
        AuthorizationScope[] scopes={scope};
        SecurityReference reference=new SecurityReference("token",scopes);
        List refList=new ArrayList();
        refList.add(reference);
        SecurityContext context=SecurityContext.builder().securityReferences(refList).build();
        List ctxList=new ArrayList();
        ctxList.add(ctxList);
        docket.securityContexts(ctxList);
        return docket;
    }
}

上面是swagger的配置类，下面是主启动类，卡我好几天了奇怪的很

package com.example.emos.wx;




import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;


@ServletComponentScan
@SpringBootApplication
public class EmosWxApiApplication {

    public static void main(String[] args) {
        SpringApplication.run(EmosWxApiApplication.class, args);
    }

}
