springboot-mysql-pagehelper集成
pagehelperjar：
<dependency>

</dependency>application.properties配置：
#pagehelper,方言
pagehelper.helperDialect=mysql
pagehelper.reasonable=true
pagehelper.supportMethodsArguments=true
pagehelper.pageSizeZero=true
pagehelper.params=count=countSql分页插件使用：（紧跟查询即可完成分页）
/**
* http://127.0.0.1:8097/hello1?a=1&b=50
* @param request
* @return
* @throws SQLException
*/
@RequestMapping(value = "/hello1", method = RequestMethod.GET)
@ResponseBody
public PageInfo<String> index1(HttpServletRequest request,@RequestParam("a") int pageNum, @RequestParam("b") int pageSize) throws SQLException {
if (StringUtils.isEmpty(pageNum)) {
pageNum=0;
pageSize=10;
}
PageHelper.startPage(pageNum, pageSize);//页码，每页显示数量
List<String> stringlist = (List<String>) iBaseService.findList("usermapper.selectuserlist",null);
PageInfo<String> pageInfo = new PageInfo<String>(stringlist);
return pageInfo;
}
使用方式二：
@RequestMapping(value = "/hello11", method = RequestMethod.GET)
@ResponseBody
public Map<String, Object> index11(HttpServletRequest request,@RequestParam("a") int pageNum, @RequestParam("b") int pageSize) throws SQLException {
if (StringUtils.isEmpty(pageNum)) {
pageNum=0;
pageSize=10;
}
PageHelper.startPage(pageNum, pageSize);//页码，每页显示数量
List<String> stringlist = (List<String>) iBaseService.findList("usermapper.selectuserlist",null);
PageInfo<String> pageInfo = new PageInfo<String>(stringlist);
Map<String, Object>datamap=new HashMap<String, Object>();
datamap.put("pagenum", pageInfo.getPageNum());
datamap.put("pagesize", pageInfo.getPageSize());
datamap.put("dataSize", pageInfo.getTotal());
datamap.put("datalist", pageInfo.getList());
return datamap;
}
