原创 com.mysql.cj.exceptions.DataConversionException: Cannot determine value type from string ‘xx‘
程序报错分析:Spring Boot+MyBatis项目在分页查询时出现DataIntegrityViolationException异常,错误提示无法从字符串'xx'确定值类型。经排查发现是实体类字段类型与数据库字段类型不匹配导致,具体为master_name字段在实体类中未定义为String类型。解决方案是将实体类对应字段类型修改为String,修改后程序运行正常。该问题属于典型的ORM框架类型映射不一致问题,通过修正实体类定义即可解决。

原创 pycharm中远程连接虚拟机,出现Automatic upload failed
出现Automatic upload failed.Connection was cancelled 主要是虚拟机没有打开,所以pycharm无法连接到虚拟机,也就无法进行本地python文件上传到虚拟机中 但是,新建远程连接时勾选了Automatically upload project files to the server ,这种行为是不建议的。 因为自动更新加载到虚拟机会占用虚拟机大量的空间,空间利用率低下。因此,出现这种问题,建议停用自动加载的选...

原创 datagrip覆写模式,前面输入内容覆写后面的内容,教你如何解决
作为刚入门大数据的编程小白,在使用datagrip这款软件写SQL语句的时候,可能会出现一些比较难受的情况:那就是发现前面的语句写错了要修改或者想要在前面的语句中加语句时,前面写的内容会覆写之前写的内容,这样又要补写后面的内容,效率太低。(具体问题如下:)这种情况可能是你进入了覆写模式,可能是你敲代码的时候不小心按了 INSERT 按键,要想切换退出覆写模式,只需要再按一下 INSERT 即可。注:两种模式都可以使用 INSERT切换。退出后的效果如下:...
