springcloud zuul网关整合swagger2，swagger被拦截问题

首先感谢一位博主的分享https://www.cnblogs.com/xiaohouzai/p/8886671.html

话不多说直接上图和代码

首先我们要有一个springcloud分布式项目

我就简单的一个eureka注册中心然后就是一个user用户然后当然就是zuul网关拉。

eureka的配置我就不多说了，我直接贴zuul网关和swagger的相关配置

zuul中的配置

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>2.3.2.RELEASE</version>
</dependency>
<--swagger2依赖-->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.7.0</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.7.0</version>
</dependency>

zuul 的application.yml

#网关配置
zuul:
  LogFilter:    #自定义过滤器的名称
    pre:        #自定义过滤器类型
      disable: true  # 是否禁用false
  prefix: /api/      #网关前缀如：http://localhost;8080/api/其他服务名
  routes:   #路由规则
    user-server: #用户的服务名
      path: /user/**  #你定义的zuul网关名

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("分布式某某系统")
                .description("某某系统接口文档说明")
                .termsOfServiceUrl("http://localhost:8081")
                .contact(new Contact("vker", "", "6492178@gmail.com"))
                .version("1.0")
                .build();
    }

    @Bean
    UiConfiguration uiConfig() {
        return new UiConfiguration(null, "list", "alpha", "schema",
                UiConfiguration.Constants.DEFAULT_SUBMIT_METHODS, false, true, 60000L);
    }
}

import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Component;
import springfox.documentation.swagger.web.SwaggerResource;
import springfox.documentation.swagger.web.SwaggerResourcesProvider;

import java.util.ArrayList;
import java.util.List;

@Component
@Primary
public class DocumentationConfig implements SwaggerResourcesProvider {

    @Override
    public List<SwaggerResource> get() {
        List<SwaggerResource> resources = new ArrayList<>();
        //第一个参数随便写，中间的参数是你zuul中application中的配置路径，第三是版本信息，随意
        resources.add(swaggerResource("随便填", "/api/user/v2/api-docs", "2.0"));
        return resources;
    }

    private SwaggerResource swaggerResource(String name, String location, String version) {
        SwaggerResource swaggerResource = new SwaggerResource();
        swaggerResource.setName(name);
        swaggerResource.setLocation(location);
        swaggerResource.setSwaggerVersion(version);
        return swaggerResource;
    }
}

然后就是user的配置

    <artifactId>springfox-swagger-ui</artifactId>

</dependency>

@Configuration

public class Swagger2Config {
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为当前包下controller生成API文档
                .apis(RequestHandlerSelectors.basePackage("com.cn.me.controller"))
                //为有@Api注解的Controller生成API文档

                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("xxxxx")//自己定义标题
                .description("部门、用户等接口")
                .version("1.0")
                .build();
    }
}
