在维护老项目的时候需要对部分分页进行手动修改、方式是获取前端的分页参数 page以及rows、 new PageRequest对象把分页参数传进去、通过 queryable.setPageable(pageable);保存、最后进行调用。

完整代码如下：

    @ResponseBody@RequestMapping(value = "getLbjzkList", method = RequestMethod.GET)@PageableDefaults(sort = "id=desc")private void ajaxList(Queryable queryable, PropertyPreFilterable propertyPreFilterable, HttpServletRequest request,HttpServletResponse response) throws IOException {EntityWrapper<LbjZk> entityWrapper = new EntityWrapper<LbjZk>(entityClass);propertyPreFilterable.addQueryProperty("id");propertyPreFilterable.addQueryProperty("name");Integer page= Integer.parseInt(request.getParameter("page").toString());Integer rows= Integer.parseInt(request.getParameter("rows").toString());// 预处理queryable.setPageable(new PageRequest(page, rows));QueryableConvertUtils.convertQueryValueToEntityValue(queryable, entityClass);SerializeFilter filter = propertyPreFilterable.constructFilter(entityClass);PageJson<LbjZk> pagejson = new PageJson<LbjZk>(lbjZkService.list(queryable,entityWrapper));String content = JSON.toJSONString(pagejson, filter);StringUtils.printJson(response, content);}

PageJson分页工具类：

package com.railway.core.model;import java.io.Serializable;
import java.util.List;import com.railway.core.query.data.Page;/*** 页面展示分页* * @author lyy** @param <T>*/
public class PageJson<T> implements Serializable {private static final long serialVersionUID = 1L;private long page = 1;// 当前页private long rows = 10;// 每页显示记录数private long total; // 总数private long totalPages; // 总页数private List<T> results; // 结果public PageJson() {}public PageJson(List<T> results) {this(0, Long.MAX_VALUE, Long.MAX_VALUE, results);}public PageJson(Page<T> page) {this(page.getNumber(), page.getSize(), page.getTotalElements(), page.getContent());}public PageJson(long page, long rows, long total, List<T> results) {this.page = page;this.rows = rows;this.total = total;this.results = results;this.totalPages = getRows() == 0 ? 1 : (int) Math.ceil((double) total / (double) getRows());}public long getPage() {return page;}public void setPage(long page) {this.page = page;}public long getRows() {return rows;}public void setRows(long rows) {this.rows = rows;}public long getTotal() {return total;}public void setTotal(long total) {this.total = total;}public long getTotalPages() {return totalPages;}public List<T> getResults() {return results;}public void setResults(List<T> results) {this.results = results;}}
