Spring Boot 应用程序错误: 数据完整性违规异常 (email 字段过长)

此错误报告了一个数据完整性违规的异常。具体地，错误发生在插入用户数据时，'email' 字段的数据长度超过了数据库列的限制。

解决这个问题的方法是缩短'email' 字段的长度，使其符合数据库列的限制。可以通过修改数据库表的定义或者在插入数据之前截断'email' 字段的值来解决这个问题。

建议:

1. 检查数据库表定义，确认'email' 字段的长度是否足够。如果长度不够，需要修改数据库表的定义，增加'email' 字段的长度。
2. 在插入数据之前，对'email' 字段进行截断，使其长度符合数据库列的限制。

注意:

请根据实际情况选择合适的解决方法。如果无法修改数据库表定义，只能通过截断'email' 字段的方式解决问题。

其他:

如果以上方法无法解决问题，请参考 MySQL 文档，了解 Data truncation 异常的其他解决方法。
