Ajax pass the array to the background, the background Spring MVC accepts an array of parameters
The front end of the following code, passing an array, receiving background List <String>:
var arrayData = [];
arrayData.push("xxx");
arrayData.push("yyy");
$.post(url,{arrayData : arrayData},function(data,status) {
//do something
});
Background code as follows:
@RequestMapping("test")
@ResponseBody
public Message test(@RequestParam(value="arrayData[]") List<String> arrayData){
//do something
return data;
}
There are two points to note:
- Use annotations@RequestParam
- Parameter values annotation in to add[ ]
Note: if arrayData only one value, and this value has a comma, for example:
arrayData.push("xxx,yyy")
Such data, when received back, list there will be two elements, namely "xxx" and "yyy"
If there are a plurality of deployment arrayData values, for example:
arrayData.push("xxx,yyy")
arrayData.push("aaa,bbb")
Such data, received the background, it does not split apart, that list there will be two elements, namely, "xxx, yyy" and "aaa, bbb";
So, if by virtue of their own data, so try not to use a comma; if you want to transfer the data itself, so, it can be replaced with other characters first comma, and then the background reception, back to back.
