java spring boot HTTP POST请求不工作

Question

对于我的应用程序，我正在编写一个POST请求，从一个复选框列表中发送参数数组。它对get请求有效，但对post请求无效。我的代码中有什么错误。

$(".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 : "POST",
            url : '/rest/channelstats/my/rest/controller',
            data : {
            //  monitoring : monitoring,
            //  nonMonitoring: nonMonitoring,
                monitoringLength: monitoringLength,
                nonMonitoringLength: nonMonitoringLength,

            },
            success : function(data) {

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


            }


});


    })

@RequestMapping(value="/rest/channelstats/my/rest/controller",method = RequestMethod.POST)
public void monitorKeywords(@RequestParam(value="monitoringLength",required=true)int monitoringLength,@RequestParam(value="nonMonitoringLength",required=true)int nonMonitoringLength){
    System.out.println("MonitoringLength =>" +monitoringLength);
    System.out.println("NonMonitoringLength=>" +nonMonitoringLength);

}

}

它适用于HTTP GET请求，但不适用于POST请求。我应该如何解决这个问题呢？

Answer 1

根据您的jquery post请求，您应该使用DAO（数据访问对象）解析请求数据。因此您应该添加类request

public class Request {

    private int monitoringLength;
    private int nonMonitoringLength;

    //getters and setters
} 

并将controller更改为

@RequestMapping(value="/rest/channelstats/my/rest/controller",method = RequestMethod.POST)
public void monitorKeywords(@RequestBody Request request){
    System.out.println("MonitoringLength =>"+request.getMonitoringLength());            
    System.out.println("NonMonitoringLength=>"+request.getNonMonitoringLength());
}
