把整张表作为参数传递

 html部分，是个动态的表格

<form method="post" id="nform" action="shywpt/team/ryxxNew">
    <input name="fzfwStr" id="fzfwStr" type="hidden"/>
                <h3>人员信息新增</h3>
                <table cellpadding="5"> 
                   <tr>
                        <td>负责范围(采油厂):</td>

                        <td>
                            <!-- <input id="sccj" class="easyui-combobox" name="sccj" readonly=true
                                data-options="valueField:'code',textField:'name',url:''" />  -->
                            <input id="cyc" name="cyc"
                                   class="easyui-combobox" data-options="

										valueField:'id',

										onSelect: function(rec){
											var url =  encodeURI('shywpt/team/getGuanliqu?id='+rec.id+'&name='+rec.name);
									        $('#glq').combobox('reload', url);
								        },
								        onChange:function(newValue,oldValue){
									        $('#glq').combobox('clear');
									    }
										"/>

                        </td>
                        <td>负责范围(管理区):</td>

                        <td>
                            <input id="glq" name="glq" class="easyui-combobox" multiple=true data-options="

												"/>

                        </td>


                    </tr>
                    <tr>
                        <td colspan=3>
                            <table id="fzfw" style="width:550px;"></table>
                            <br/>
                        </td>
                    </tr>
 </table>
</form>

js部分

//对管理区绑定选择事件
    $("#glq").combobox({
        onSelect: function (record) {
            //添加行
            $('#fzfw').datagrid('appendRow', {
                cycid: record.cycid,
                cycmc: record.cycmc,
                glqid: record.glqid,
                glqmc: record.glqmc,
                ryid: '${id}',
                oper: '<input type="button" value="删除" onclick="delRow(this)"/>'
            });
        }
    })

    //初始化管理区
    function initGlq() {
        //初始化fzfw
        $("#fzfw").datagrid({
            url: "",
            striped: true,
            singleSelect: true,
            autoRowHeight: true,
            nowrap: false,
            columns: [[
                {field: 'cycid', title: '采油厂ID', hidden: true, halign: 'center'},
                {field: 'cycmc', title: '采油厂', width: 180, halign: 'center'},
                {field: 'glqid', title: '管理区ID', hidden: true, halign: 'center'},
                {field: 'glqmc', title: '管理区', width: 140, halign: 'center'},
                {field: 'ryid', title: '人员ID', hidden: true, width: 130, halign: 'center'},
                {field: 'oper', title: '操作', width: 100, halign: 'center'},
            ]],
        });
    }

    //删除负责范围表格的行记录
    function delRow(obj) {
        //删除一行记录，因为是easyui的样式，所以向上找3层才是tr
        var tr = obj.parentNode.parentNode.parentNode;
        $("#fzfw").datagrid("deleteRow", tr.rowIndex);
        var rows = $('#fzfw').datagrid('getRows');
        $('#fzfw').datagrid('loadData', rows);
    }

    //保存
    function doSave(dialog) {

        if($("#ywsxm").combobox("getValue")!=null){
            $("#id").val($("#ywsxm").combobox("getValue"));
            $("#ywsxm").combobox('setValue', $("#ywsxm").combobox("getText"));
        }

        //负责范围
        var fzfwData = $('#fzfw').datagrid('getData');
        for (var i = 0; i < fzfwData.rows.length; i++) {
            $('#fzfw').datagrid('endEdit', i);
        }
        var fzfwDataObj = fzfwData.rows;
        $("#fzfwStr").val($.toJSON(fzfwDataObj));
        $("#dwmc").val($("#dwid").combobox('getText'));
        //获得父页面datagrid，用于刷新页面
        var datagrid = dialog.getData("datagrid");
        $('#nform').form('submit', {
            success: function (data) {
                var data = eval('(' + data + ')'); // change the JSON string to javascript object
                if (data.meta.success) {
                    $.messager.alert('', '创建成功', 'info', function () {
                        dialog.getData('datagrid').datagrid('reload');
                        dialog.close();
                    });
                } else {
                    $.messager.alert('error', data.meta.message);
                }
            }
        });
    }

 controller层就是直接用实体类传参，实体类中的定义：private String fzfwStr;

@RequestMapping(path = "ryxxNew", method = RequestMethod.POST, produces = "text/html;charset=UTF-8")
    @ResponseBody
    public String doRyxxNew(Dwryxx dwryxx) {
        dwxxService.insertRyxx(dwryxx);
        return "{'meta':{'success':true,'message':'ok'},'data':null}";
    }

service层

    @Transactional
    public void insertRyxx(Dwryxx dwryxx) {
        mybatisRepository.insert(INSERTRYXX, dwryxx);
        String rystr = dwryxx.getFzfwStr();

        List<Map<String, String>> ryList = JsonUtils.fromJson(rystr,
                new TypeReference<List<Map<String, String>>>() {
                });
        if (ryList != null && ryList.size() > 0) {
            for (int i = 0; i < ryList.size(); i++) {
                Map<String, String> map = ryList.get(i);
                Ryfzfw ryfzfw = new Ryfzfw();
                ryfzfw.setId(UUID.randomUUID().toString());
                ryfzfw.setCycid(map.get("cycid"));
                ryfzfw.setCycmc(map.get("cycmc"));
                ryfzfw.setGlqid(map.get("glqid"));
                ryfzfw.setGlqmc(map.get("glqmc"));
                ryfzfw.setRyid(dwryxx.getId());
                mybatisRepository.insert(INSERTFZFW, ryfzfw);
            }
        }


    }
