Spring MVC前台先后台传递一个List

后台代码

@RequestMapping(value = "/saveRoleRight",method = RequestMethod.POST)@ResponseBodypublic MessageTO saveRoleRight(HttpServletRequest request,@RequestBody List<Temp> roleList){MessageTO res=new MessageTO();System.out.println(111);//已将数据传入return res;}

前台js

function saveData(){var arr=new Array();$.ajax({url:"../saveRoleRight",//请求的后台地址type:"POST",//强求方式contentType:"application/json",//数据类型data:JSON.stringify(arr),//将数组转换为json对象error:function(a,b){//错误alert(2);},success:function(data){//成功alert(1);}});}

//这里面引用了一个js,是将对象转换为JSON对象
