Springmvc passing and receiving array parameters

How to pass an array in the Java URL, how does the SPRINGMVC Framework controller class receive array parameters?

Here's how to pass an array parameter in a URL:

Dd.do?titles[]=col1&titles[]=col2&titles[]=col3

or using Ajax to pass:

var param = {titles:[ ‘col1‘ , ‘col2‘ , ‘col3‘ ]};  $.ajax({url: "dd.php" , type: "post" , data:param, async: false , dataType: "json" ,/**这个类型很重要 */ cache: false , error: function (data) {           rtnObj = data.responseText;       }, beforeSend: function (XMLHttpRequest) {           //ajaxStart();       }, complete: function (XMLHttpRequest, textStatus) {           //ajaxComplete();       }, success: function (data) {           rtnObj = data;       }});

In Springmvc, the controller class receives array parameters in the method:

@RequestMapping (value= "/save" , method = RequestMethod.POST)  @ResponseBody public String save( @RequestParam (value = "titles[]" ) String[] titles){       System.out.println(titles);       return null ;  }
