接口文档？AYPI？全流程？小白新手教程

YAPI链接 

https://yapi.pro/

1.添加项目

2.填写项目名称

3.添加接口

 

4.填接口名称，接口路径，有需要的可以填接口分类。 

比如项目中需要两大模块，管理员与病患，且接口数目较多，就可以分类接口，以便更好管理。

这里的接口分类填了就行，不用后续其他操作。

 5.最终效果

6.与后端连接，打开idea 

package com.simplesin.config;
import com.simplesin.json.JacksonObjectMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import java.util.List;

/**
 * 配置类，注册web层相关组件
 */
@Configuration
@Slf4j
public class WebMvcConfiguration extends WebMvcConfigurationSupport {

    /**
     * 通过knife4j生成接口文档
     * @return
     */
    @Bean
    public Docket docket() {
        ApiInfo apiInfo = new ApiInfoBuilder()
                .title("simplesin的项目接口文档")
                .version("2.0")
                .description("simplesin的项目接口文档")
                .build();
        Docket docket = new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.simplesin.controller"))
                .paths(PathSelectors.any())
                .build();
        return docket;
    }
}

7.在application.yml我配置的是8080

server:
  port: 8080

spring:
  profiles:
    active: dev
  main:
    allow-circular-references: true
  datasource:
    druid:
      driver-class-name: ${simplesin.datasource.driver-class-name}
      url: jdbc:mysql://${simplesin.datasource.host}:${simplesin.datasource.port}/${simplesin.datasource.database}?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true
      username: ${simplesin.datasource.username}
      password: ${simplesin.datasource.password}
  redis:
    host: localhost
    port: 6379
    lettuce:
      pool:
        max-active: 10
        max-idle: 10
        min-idle: 1
        time-between-eviction-runs: 10s
#mybatis:
#  #mapper配置文件
#
#  type-aliases-package: com.simplesin.entity

mybatis-plus:
  type-aliases-package: com.simplesin.entity
  global-config:
    db-config:
      id-type: auto
  configuration:
    #开启驼峰命名
    map-underscore-to-camel-case: true
  mapper-locations: classpath:mapper/*.xml
logging:
  level:
    com:
      simplesin:
        mapper: debug
        service: info
        controller: info

simplesin:
  jwt:
    # 设置jwt签名加密时使用的秘钥
    admin-secret-key: itcast
    # 设置jwt过期时间
    admin-ttl: 7200000
    # 设置前端传递过来的令牌名称
    admin-token-name: token

 8.输入localhost，电脑就会补全后面的信息

 9.最终效果
