spring-boot2.7.8添加swagger

一、新建项目swaggerdemo

二、修改pom.xml

注意修改：spring-boot-starter-parent版本为：2.7.8

添加依赖：

springfox-swagger2
springfox-swagger-ui
springfox-boot-starter

修改：application.yml

matching-strategy: ant_path_matcher

server:
  port: 81
spring:
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher

添加SwaggerConfig

package com.saas.swaggerdemo;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.RestController;
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;

@EnableOpenApi
@Configuration
public class SwaggerConfig {
    @Bean
    public ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Swagger Test App Restful API")
                .description("swagger test app restful api")
                .version("1.0.0.0")
                .build();
    }

    @Bean
    public Docket createRestApi(ApiInfo apiInfo) {
        return new Docket(DocumentationType.OAS_30)
                .apiInfo(apiInfo)
                .groupName("SwaggerGroupOneAPI")
                .select()
                .apis(RequestHandlerSelectors.withClassAnnotation(RestController.class))
                .paths(PathSelectors.any())
                .build();
    }
}

二、添加控器器

ProductController.java

package com.saas.swaggerdemo.controllers;

import com.saas.swaggerdemo.ProductDto;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

@RestController
@Api(value = "ProductController")
@RequestMapping("/products")
public class ProductController {

    @ApiOperation(value = "保存产品")
    @PostMapping("save")
    public boolean SaveProduct(@RequestBody ProductDto productDto) {
        return true;
    }
}

ProductDto.java

package com.saas.swaggerdemo;
public class ProductDto {
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    private  String name;
}

运行效果：
