A. easyui datagrid 数据绑定 java

后台：

只需要将url绑定就好，他会自动获得你的数据，进行显示，希望能帮助到你

B. 菜鸟求教，java easyui 怎么用DataGrid 的属性queryParams给后台传参数，DataGrid的代码如下：

你上面的dataGrid应该只是个本地的例子吧，没有和后台交互吧!因为我看你的url="mytable",感觉不像是action请求；因为你说的queryParams是需要发送远程请求时，才起作用的；

这样就会重新去发送新的url请求，初始化datagrid新的数据了；（我这样的写法是动态的设置请求参数，如果你想直接在datagird初始化中添加参数，你就直接在初始化datagird的时候添加属性queryParams : {参数名:'参数值',}）

C. 如何用easyui+JAVA 实现动态拼凑datagrid表格

首先datagrid表格式智能显示的只要你的json字符串符合特定格式就可以正确显示。所以你需要做的就是在后台拼接好字符串发送到前台就行了，datagrid会自动显示。
json字符格式：注意格式一定要正确。
{"total":28,"rows":[
{"proctid":"FI-SW-01","proctname":"Koi","unitcost":10.00,"status":"P","listprice":36.50,"attr1":"Large","itemid":"EST-1"},
{"proctid":"K9-DL-01","proctname":"Dalmation","unitcost":12.00,"status":"P","listprice":18.50,"attr1":"Spotted Alt Female","itemid":"EST-10"},
]}
上面是后台拼接好的字符串，可以使用fastjson-1.1.28.jar架包；架包只能将类或list或map转为json字符串，而我们要的数据中多了两个字段：total和rows，所以还要建立一个封装类。类中定义两个变量：total和rows，rows是一个我们的数据集合，将这个类转换成json字符串发送到前台就可以了。

如果前台要特定格式或样式显示可以使用datagrid的属性来设置：
$('#dg').datagrid({
url:'datagrid_data.json',

columns:[[
{field:'code',title:'Code',width:100},
{field:'name',title:'Name',width:100},
{field:'price',title:'Price',width:100,
formatter: function(value,row,index){
if (row.user){
return row.user.name;
} else {
return value;
}
}

}
]]
});
这样基本上就可以实现我们所需要的了。

D. Java项目用easyui做树形列表后台代码怎么来准备数据啊不要概括型答案，要详细过程的，谢谢！

教你怎么解决,下次就知道了.

访问这个地址,是easyui的官网范例,可以看到范例的html里面有这个配置treegrid_data3.json

所以官方的代码用的是这个地址返回的json:http://www.jeasyui.net/demo/treegrid_data3.json.

访问上面的地址,返回值就是你要的:

{"total":9,"rows":[
{"id":1,"region":"Wyoming"},
{"id":11,"region":"Albin","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":1},
{"id":12,"region":"Canon","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":1},
{"id":13,"region":"Egbert","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":1},
{"id":2,"region":"Washington"},
{"id":21,"region":"Bellingham","f1":2000,"f2":1800,"f3":1903,"f4":2183,"f5":2133,"f6":1923,"f7":2018,"f8":1838,"_parentId":2},

],"footer":[
{"region":"Total","f1":14000,"f2":12600,"f3":13321,"f4":15281,"f5":14931,"f6":13461,"f7":14126,"f8":12866}
