Controller层
//添加
@RequestMapping("adds")
@ResponseBody
public void addType(String tName,String tCrtate,String tJiao){
AuditType a=new AuditType();
a.settName(tName);
a.settCrtate(tCrtate);
a.settJiao(tJiao);
auditTypeService.addty(a);

}

    //添加
    @Transactional
   public void addty(AuditType auditType){
       auditTypeRep.save(auditType);
   }


        页面HTML
        <script>
    function add() {
        $("#adddlg").dialog("open");

你ajax的 url:"adds?tName="+tName+"&&tCrtate="+tCrtate+"&&tJiao="+tJiao,这里错了。
应该是这样：
$.ajax({
url:"adds",
data:{tName: tName,tCrtate: tCrtate,tJiao: tJiao}
dataType:"json",
type:"post",
success:function(data){
if(data>0) {
$.messager.alert("系统提示",'新增成功');
/*$("#dg1").datagrid("reload");
$("#adddlg").dialog("close");*/
}else{
$.messager.alert("系统提示",'新增失败');
}
},
/* error:function (data) {
$.messager.alert("系统提示",'错误');
}*/
})
