如何配置swgger以及使用方法(postman,apipost)

一.如何配置swgger

1.引入依赖:我配置的是swgger2,如果需要其他版本,可以自行百度

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.4.0</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.4.0</version>
        </dependency>

2.配置config(配置文件)

package com.example.springbootdemo.config;

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.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
@Configuration
@EnableSwagger2
public class Swagger2 {
//swagger2的配置文件，这里可以配置swagger2的一些基本的内容，比如扫描的包等等
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为当前包路径
                .apis(RequestHandlerSelectors.basePackage("com.example.springbootdemo"))//这里是你springboot启动器的路径相对路径
                .paths(PathSelectors.any())
                .build();
    }
    //构建 api文档的详细信息函数,注意这里的注解引用的是哪个
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                //页面标题
                .title("Spring Boot 测试使用 Swagger2 构建RESTful API")
                //创建人
                .contact(new Contact("xiaoLiang", "http://www.baidu.com", ""))
                //版本号
                .version("1.0")
                //描述
                .description("API 描述")
                .build();
    }
 
 
}

3.编写一个controller测试一下

package com.example.springbootdemo.controller;

import com.example.springbootdemo.entity.User;
import org.springframework.web.bind.annotation.*;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;

@RestController
@RequestMapping("/user")
@Api(value = "/user")
public class SwagController {
 
 
    @ApiOperation(value = "查询用户", notes = "查询用户")
    @PostMapping(value = "/getName")
    @ResponseBody
    public User getName(@RequestBody User userName) {
        System.out.println(userName.toString());
        return userName;
    }
 
 
}

4.我没有配置端口号默认就是localhost:8080/doc.html访问swgger2

 5.postman是一样的
