作者：曾将
这篇文章主要给大家介绍了关于java easyUI实现自定义网格视图的相关资料，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧
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 contactNumber;
private String color;

private int status;
private int isDelete;
private int isAdmindel;
private int isTop;
private int replyNumber;
private int readNumber;
private int thumbNumber;

private int type;

private List<BsChannelPostAttach> channelPostAttach;//附件
private String nickName;
