2. Use

Many articles on the network will say that it needs to be configured in application.properties.

In fact, there is no need at all, and the default settings already meet most of the needs.

Just use it directly.

@ RequestMapping (value = "getApps.do") public String getApps (Apps apps) {PageHelper.startPage (apps.getPageNum (), apps.getPageSize ()); ArrayList appsList = appsService.getApps (apps); PageInfo appsPageInfo = new PageInfo (appsList); return JSON.toJSONString (appsPageInfo);}

PageHelper.startPage (the number of pages to be displayed and the number of pages to be displayed per page)

The next line is followed by the query statement, do not write anything else, otherwise there will be no effect.

PageHelper.startPage (apps.getPageNum (), apps.getPageSize ()); ArrayList appsList = appsService.getApps (apps)

This only has a paging effect, and there is no detailed information on the total number of pages and so on.

If you have a need for the number of pages, you need to add the following line

PageInfo appsPageInfo = new PageInfo (appsList)

This satisfies all the paging requirements.
