java easyUI实现自定义网格视图实例代码

前言

easyui是一种基于jQuery的用户界面插件集合。

easyui为创建现代化，互动，JavaScript应用程序，提供必要的功能。

使用easyui你不需要写很多代码，你只需要通过编写一些简单HTML标记，就可以定义用户界面。

本文主要给大家介绍了关于java easyUI自定义网格视图的相关内容，下面话不多说了，来一起看看详细的介绍吧

方法如下：

一：前台代码如下

二：后台返回的数据格式

后台返回的数据格式和经典的easyui的数据格式是一样的

数据格式：

　　{"total":67,"errmsg":"查询成功","errcode":1,"rows":[{"postId":77,"dealType":0,"title":"理解","partNo":null,"content":"理解[图片]","location":null,"tradeType":0,"brandId":0,"quantity":0,"contacts":"SakuraAoi","contactNumber":null,"color":null,"channelId":1,"createDate":"2018-10-16 10:12:19","updateDate":null,"status":0,"isDelete":0,"isAdmindel":0,"isTop":0,"replyNumber":0,"readNumber":0,"thumbNumber":0,"authorId":0,"isOem":0,"type":0,"amount":0.0,"channelPostAttach":[{"attachId":99,"postId":77,"uploadDate":1539655939000,"attachName":"record-attach/sell/371-20181016101221.png","type":10121001,"typeName":null,"attachNameUrl":""}],"nickName":"SakuraAoi","avatar":"","channelName":"新车交易","brandName":"长安铃木","startDate":null,"endDate":null,"brandIds":null,"channelIds":null,"strBrandIds":null,"strChannelIds":null,"begin":0,"end":0,"dealTypes":null,"isDeletes":null,"item":null,"value":0,"userId":0,"actId":0,"dealTypeName":null,"tradeTypeName":null,"isTopName":null,"createDate2":null}]}

三：视图效果

四：后台数据的获取

后台数据的获取为一对多，因为一个帖子会包含多个图片附件。

帖子实体类：

public class BsChannelPost {
 private int postId;
 private int dealType;
 private String title;
 private String partNo;
 private String content;
 private String location;
 private int tradeType;
 private int brandId;
 private int quantity;
 private String contacts;
 private String contactNumber;
 private String color;
 private int channelId;
 @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
 private Date createDate;
 @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
 private Date updateDate;
 private int status;
 private int isDelete;
 private int isAdmindel;
 private int isTop;
 private int replyNumber;
 private int readNumber;
 private int thumbNumber;
 private int authorId;
 private int isOem;
 private int type;
 private double amount;
 private List<BsChannelPostAttach> channelPostAttach;//附件

 private String nickName;
 private String avatar;
 private String channelName;
 private String brandName;

 private String startDate;
 private String endDate;
 private List<Integer> brandIds;
 private List<Integer> channelIds;
 private String strBrandIds;
 private String strChannelIds;
 private int begin;
 private int end;
 private String dealTypes;
 private String isDeletes;

 private String item;
 private int value;
 private int userId;
 private int actId;

 private String dealTypeName;
 private String tradeTypeName;
 private String isTopName;
 private String createDate2;
}

附件实体类：

import lombok.Data;
@Data//lombok 免写get set
public class BsChannelPostAttach {
 private int attachId;
 private int postId;
 private Date uploadDate;
 private String attachName;
 private int type;
 private String typeName;
 private String attachNameUrl;
}
