记一次ajax传递数组引发的入参问题

后台ajax

var check &＃61; [];$(&＃39;#datagrid&＃39;).find(&＃39;:checkbox&＃39;).each(function(){ if($(this).is(&＃39;:checked&＃39;)){check.push($(this).val());}});var row &＃61; {};row[&＃39;adminIds&＃39;] &＃61; check;row[&＃39;adminIdOlds&＃39;] &＃61; oldCheck;row[&＃39;roleId&＃39;] &＃61; $("#roleId").val();$.ajax({url : &＃39;${ctx}/admin/authorizedUser&＃39;,type : &＃39;post&＃39;,data : JSON.stringify(row),headers: { &＃39;Accept&＃39;: &＃39;application/json&＃39;,&＃39;Content-Type&＃39;:&＃39;application/json&＃39; },datatype: &＃39;json&＃39;,success : function(data) {showAlert(data);if(data.status&＃61;&＃61;"success"){parent.modal.close();}},error : function() {dangerAlert();}});

后台接收使用&＃64;RequestBody

使用对象来接受

若后台ajax改为如下&＃xff1a;即去掉headers定义

var check &＃61; [];$(&＃39;#datagrid&＃39;).find(&＃39;:checkbox&＃39;).each(function(){ if($(this).is(&＃39;:checked&＃39;)){check.push($(this).val());}});var row &＃61; {};row[&＃39;adminIds&＃39;] &＃61; check;row[&＃39;adminIdOlds&＃39;] &＃61; oldCheck;row[&＃39;roleId&＃39;] &＃61; $("#roleId").val();$.ajax({url : &＃39;${ctx}/admin/authorizedUser&＃39;,type : &＃39;post&＃39;,data : row,datatype: &＃39;json&＃39;,success : function(data) {showAlert(data);if(data.status&＃61;&＃61;"success"){parent.modal.close();}},error : function() {dangerAlert();}});

则后台接收可使用

&＃64;ResponseBody&＃64;RequestMapping("authorizedUser")public Map authorizedUser(&＃64;RequestParam(value &＃61; "adminIds[]", required &＃61; true) String[] adminIds,&＃64;RequestParam(value &＃61; "adminIdOlds[]", required &＃61; true) String[] adminIdOlds) {
}
