springboot集成swagger3

  1 pom.xml增加

  <dependency>

    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>
2  增加config文件
      新增 Swager3Config 文件，代码如下

package com.example.app.config;

import org.apache.catalina.User;
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.oas.annotations.EnableOpenApi;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

@Configuration
@EnableOpenApi
public class Swagger3Config {


    @Bean
    public Docket api() {
        return new Docket(DocumentationType.OAS_30)
                .apiInfo(apiInfo()) //应用文档基本信息
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.app")) // swagger扫描路径
                .paths(PathSelectors.any()) // 应用于包下所有路径
                .build(); // 设置全局通用参数
    }

    /**
     * 文档基本信息
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("swagger口文档")
                .description("swagger接口文档")
                .version("2.0")
                .build();
    }

}

  新增  MyWebMvcConfigurer文件,代码如下

package com.example.app.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

@Configuration
public class MyWebMvcConfigurer extends WebMvcConfigurationSupport {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        // swagger配置
        registry.
                addResourceHandler("/swagger-ui/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/springfox-swagger-ui/")
                .resourceChain(false);
    }

}

然后在接口controller 配置就行

url 访问  ip:port/swagger-ui/index.html
