How to connect layui and backend

Layui front and backend data interaction:

layui has its own set of specific data format interactions (this is very important), and the code must be parameter :0, msg: "", count: data size (int), data: "Data List". Generally we choose to encapsulate and return the receiving class.

Layui tool class code

public class Layui extends HashMap { public static Layui data(Integer count,List data){ Layui r = new Layui(); r.put("code", 0); r.put("msg", ""); r.put("count", count); r.put("data", data); return r; } }

PageUtils is optional here, you can encapsulate it yourself

@Data public class PageUtils implements Serializable { private static final long serialVersionUID = -1202716581589799959L; //总记录数 private int totalCount; //每页记录数 private int pageSize; //总页数 private int totalPage; //当前页数 private int currPage; //列表数据 private List list; /** * 分页 * @param list 列表数据 * @param totalCount 总记录数 * @param pageSize 每页记录数 * @param currPage 当前页数 */ public PageUtils(List list, int totalCount, int pageSize, int currPage) { this.list = list; this.totalCount = totalCount; this.pageSize = pageSize; this.currPage = currPage; this.totalPage = (int)Math.ceil((double)totalCount/pageSize); } }
