Implementing table server-side paging and fuzzy query based on SpringMVC+Bootstrap+DataTables-javaTutorial-php.cn

Preface

Based on SpringMVC+Bootstrap+DataTables, data table server-side paging, fuzzy query (non-DataTables Search), and page asynchronous refresh are implemented.

Note: The sp:message tag uses SpringMVC internationalization

Controller processing method, responsible for querying the tables required on the page Data, returned after formatting Json.

@RequestMapping(value="/goodsType/getData", produces = "text/json;charset=UTF-8")
@ResponseBody
public String getData(HttpServletRequest request, QueryCondition query) {
DatatablesView<GoodsType> dataTable = goodsTypeService.getGoodsTypeByCondition(query);

Service business processing class, mainly counts the number of records based on query conditions, and queries the current page data list

public DatatablesView<GoodsType> getGoodsTypeByCondition(QueryCondition query) {
DatatablesView<GoodsType> dataView = new DatatablesView<GoodsType>();
//构建查询条件
WherePrams where = goodsTypeDao.structureConditon(query);
Long count = goodsTypeDao.count(where);
List<GoodsType> list = goodsTypeDao.list(where);
dataView.setRecordsTotal(count.intValue());
dataView.setData(list);
return dataView;
}

The Dao layer is the basic database query operation, which is omitted here...

Query conditions only use keyword fuzzy query, which can be added dynamically according to business needs Other query conditions need to be processed accordingly in the background.
