问题描述
当我单击编辑按钮时,dataTable中的值应以表格形式显示。但不知何故,它不起作用。以下是我的参考代码。
When i clicked the edit button the values from dataTable should display in form. But somehow it doesn't work. Below are my codes for reference.
调用数据表:
:@RequestParam(value = "params") String params这是因为默认情况下, @RequestParam 尝试获取值。
This happens because, by default, @RequestParam tries to get the value. It then returns an exception when the value is not found.
因此,您有两种方法可以解决此问题,
So you have two ways to resolve this,
您可以为URL / check 提供一个 params 变量,或者
您可以将 @RequestParam 的要求改为false:
You can change the @RequestParam requirement to false like this:
@RequestParam(value = params,required = false)字符串参数
@RequestParam(value = "params", required = false) String params
请注意,这是一个示例反映您的情况和问题。古德·卢克。
