设计的数据库表结构:

接下来一些简单配置自己百度就好代码最好自己实现

主要说下遇到的价格问题:

***************************
APPLICATION FAILED TO START
***************************
Description:
Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.

If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

Mybatis没配置好数据库环境原因在你的yml写下:

spring:
    datasource:
        username: root
        password: 123456
        url: jdbc:mysql://127.0.0.1:3306/test?            
    characterEncoding=utf8&useSSL=false&autoReconnect=true
        driver-class-name: com.mysql.jdbc.Driver

mybatis:
  mapper-locations: classpath:mapper/*Mapper.xml
  type-aliases-package: com.best800.demologin.model.dto

2.swagger只显示样式但是不具体显示接口

很蠢的答案包名可能使从网上复制的答案但是包名没改过来

3.swagger页面报错404或者

Unable to infer base url. 
This is common when using dynamic servlet registration or when the API is behind an API Gateway.
The base url is the root of where all the swagger resources are served. For e.g. if the api is available at 
http://example.org/api/v2/api-docs then the base url is http://example.org/api/. 
Please enter the location manually:

jar包版本问题按照上述demo-login的版本即可

4.mybatis-plus 按照配置文件找不到相应的dao层和xml文件

jar包问题 mybatis-plus-boot-starter 和 mybatisplus-spring-boot-starter

5.springboot中的web项目不能访问templates中的静态资源

如果配置文件中的相关配置没有写错可能是在controller里用了@RestController注解

@RestController = @Controller + @ResponseBody 返回的json 所以在controller的返回"index.html"里返回的永远是String

6.idea里提示数据库连接时间超时可能是配置的信息有问题轻易不要改my.ini文件

如果改了报错 mysql处于启动卡死的状态要先用管理员身份打开cmd 使用命令 skilltask杀死相应的进程

在进入mysql 的目录重新启动一个cmd 执行mysql启动

7. 如果jar包导入不成功,可以尝试下mvn install 和mvn package

最后推荐几个比较有用的配件

codeglance代码的缩略图可以看做是LOL的小地图

sequence diagram 右键方法自动生成uml图方便读懂别人代码

mybatis plugin 不用多说

String manipulation 快速修改驼峰命名

最后还是贴一下配置文件吧:

  client:
    service-url:
      defaultZone: http://localhost:8080/eureka
