When using PageHelper pagination plug-in SpringBoot in, if you set pagehelper.reasonable = true, pageNum <= will check the first page 0, pageNum> pages (more than the total number), queries the last page
That is even greater than the total number of pages of incoming pages will still return data
In the configuration file, the pagehelper.reasonable changed to false to
pagehelper.reasonable=false
Official documentation wrote:
reasonable: Paging rationalization parameter defaults to false. When this parameter is set to true, pageNum <= 0, the first page queries, pageNum> pages (more than the total number), the last page queries. Default false, according to a direct query parameters.
