pagehelper分页插件

springboot-mysql-pagehelper集成

pagehelperjar：

    com.github.pagehelper
    pagehelper-spring-boot-starter
    0.1.0

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 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 stringlist = (List) iBaseService.findList("usermapper.selectuserlist",null);
      PageInfo pageInfo = new PageInfo(stringlist);

      return pageInfo;

}

使用方式二：

@RequestMapping(value = "/hello11", method = RequestMethod.GET)
@ResponseBody
public Map 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 stringlist = (List) iBaseService.findList("usermapper.selectuserlist",null);
      PageInfo pageInfo = new PageInfo(stringlist);
      Mapdatamap=new HashMap();
      datamap.put("pagenum", pageInfo.getPageNum());
      datamap.put("pagesize", pageInfo.getPageSize());
      datamap.put("dataSize", pageInfo.getTotal());
      datamap.put("datalist", pageInfo.getList());
      return datamap;

}
