springmvc传递和接收数组参数java url中如何传递数组，springMVC框架controller类如何接收数组参数？
下⾯介绍⼀下URL中传递数组参数⽅法：
dd.do?titles[]=col1&titles[]=col2&titles[]=col3
或者使⽤ajax⽅式传递：
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 = sponseText;
}, beforeSend:function(XMLHttpRequest) {
//ajaxStart();
}, complete:function(XMLHttpRequest, textStatus) {
//ajaxComplete();
}, success:function(data) {mvc的controller
rtnObj = data;
}});
在springMVC中controller类接收数组参数的⽅法：
@RequestMapping(value="/save", method = RequestMethod.POST)
@ResponseBody
public String save(@RequestParam(value = "titles[]") String[] titles){
System.out.println(titles);
return null;
}
