ajax内容

var plateNumber = $("#plateNumber").val();
var vehicleLab = $("#vehicleLab").val();
$.ajax({
method : "post",
url : "",
dataType : "json",
cache : false,
data : {
"plateNumber" : encodeURI(plateNumber),
"vehicleLab" : encodeURI(vehicleLab)
},
success : function(data) {

}
});

action中写法

String plateNumberstr = URLDecoder.decode(plateNumber,"UTF-8"); String vehicleLabstr = URLDecoder.decode(vehicleLab,"UTF-8");
