我正在为编辑功能运行一个jsp，由于某种原因，用于解析int id的String idTemp不断被识别为要执行更新的一些数据。

method edit in class data access cannot be applied to given types
required: int, +37 String
found: int, +36 String
reason: actual and formal argument lists differ in length您建议我做什么来保留 idTemp 字符串但又能够在不将其包含在要插入的数据中的情况下执行？

错误消息告诉您，DataAccess.java 中的 edit 方法要求您传入一个 int，后跟 37 字符串。但是，当您在 jsp 文件中调用 da.edit(...) 时，您将传入一个 int，后跟 36 字符串。
确保您传递给 edit() 的内容与方法定义匹配。我相信您缺少第三个参数:字符串描述
关于java - 类数据访问中的方法编辑无法应用于给定类型，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34035504/
