Front-end JS code:
var conditons = [];
var test1 = new Object();
test1.name="1";
test1.id="2";
var test2 = new Object();
test2.name="1";
test2.id="2";
conditons.push(test1);
conditons.push(test2);
$(function(){
$.ajax({
async:"false",
type:'post',
url:' Link ',
data:{name:"123",conditions:JSON.stringify(conditons)},
dataType : 'json',
success:function(data){
console.log(data);
},
error: function (XMLHttpRequest, textStatus, errorThrown){
alert("error");
}
});
});
Important note: Convert the array of objects to a string in the form of JSON: JSON. stringify
Back-end acquisition:
String conditions = request.getParameter("conditions");
JSONArray conditionList = JSONArray.fromObject(conditions);
