本机部署：8081
ajax请求跨域：

function initGrid2(){
$.ajax({
                type:"GET",
                url:'http://localhost:8080/x/ommon/findDept?dept_id=346', //跨域请求8080
                contentType:'application/json;charset=utf-8',
                dataType:'json',
                success:function (res) {
                alert(231);
                    $('#dg2').bootstrapTable({
         striped: true,   
       cache: false,                     
         smartDisplay: false,  
         dataType:'json',
         idField:'id',
         columns: [{
         field:'id',
         checkbox:true
         },{
           title: '序号',
           align: 'center',
           halign: 'center',
           formatter: function (value, row, index) {
             return index + 1;
           }
         }, {
