全部配置完成后，打开localhost:8080/shopping页面
页面弹出“查询错误”
看了一下源码，把返回的错误对象扔到控制台
看到了这些

我自己分析一下觉得可能是database.properties文件配置错误
这里是配置文件内容

#这里是数据库驱动，如果想换用SQLServer或者其他，需要更改pom.xml jar相关以来==依赖以及这里的驱动
driverClassName=com.mysql.jdbc.Driver
#数据库连接地址，不同数据库不一样，若换数据库请自行搜索替代方式
url=jdbc:mysql://localhost:3306/shopping
#你的数据库的用户名
userName=root
#你的数据库的密码，一定要改
password=123456

检查了一下发现和自己设置的是一样的，端口也是默认对3306开放

SQL数据库也建好了，只是里面没有任何数据

从错误堆栈那里来看是内部服务器错误，但是不知道是什么地方出了问题，能不能给分析一下。。。
猜测：

  • properties连接路径配置错误
  • 某些我不知道的MYSQL配置错误
  • 文件路径（emmmmmmm）

抱歉，之前我没有看到这个issue。今天才看到，可能你已经解决这个问题了。我还是说一下我觉得可能的导致这种问题的原因：

  1. 新建好对应的数据库之后是需要执行我放在resource目录下面的shoppingSQL语句.txt里面的建表语句先把对应的表建立起来。
  2. MySQL数据库你可能用的是8.0，在连接8.0的MySQL时旧有驱动会有问题，因此建议换成MySQL5.6尝试一下，或者搜索MySQL8.0对应的连接驱动版本以及连接方式。
