【问题描述】：

在我的应用程序中，我需要将一组参数从客户端传递到服务器端。我尝试了以下代码，但它不起作用。我需要从复选框列表中获取数据并将其传递到服务器端。 我的客户端代码

$(".add").click(function()

    monitoring.length=0;
    nonMonitoring.length=0;
    $('.modal-body input:checked').each(function() 
        monitoring.push($(this).val());
        );

    $('.addkeywords input:checked').each(function() 
        nonMonitoring.push($(this).val());
        );


//  alert(monitoring[2]+ " " + nonMonitoring[2]);
    var monitoringLength=monitoring.length;
    var nonMonitoringLength=nonMonitoring.length;


    $.ajax(
            type : "GET",
            url : '/rest/my/rest/mysql/controller',
            data : 
                monitoringLength: monitoringLength,
                nonMonitoringLength: nonMonitoringLength,
                monitoring : monitoring,
                nonMonitoring: nonMonitoring,


            ,
            success : function(data) 

            //  var keywordsList=data
                //console.log(keywordsList);
            //  htm = "" ;

                if(data=='success')
                    //  loadChannels();
                    location.reload();
                    else
                alert("failed to upload");

                


            


);



)

我的服务器端代码。

@RequestMapping("/rest/my/rest/mysql/controller")

    public void monitorKeywords(@RequestParam(value="monitoringLength",required=true)int monitoringLength,@RequestParam(value="nonMonitoringLength",required=true)int nonMonitoringLength,@RequestParam(value="monitoring",required=true)List<String> monitoring,@RequestParam(value="nonMonitoring",required=true)List<String> nonMonitoring)
        System.out.println("MonitoringLength =>" +monitoringLength);
        System.out.println("NonMonitoringLength=>" +nonMonitoringLength);
        System.out.println("Monitoring=>" +monitoring);
        System.out.println("Monitoring=>" +nonMonitoring);

不知何故，这不起作用。这是什么错误？请帮忙

【参考方案1】：

在请求参数更改列表为数组

即

@RequestParam(value="monitoring",required=true) String[] monitoring, @RequestParam(value="nonMonitoring",required=true) String[] nonMonitoring
