将请求发布到SPRING BOOT应用程序，该应用程序不是从Jquery（前端）运行的，而是从POSTMAN运行得很好

Question

在我的前端表单中,我从用户路由器名称和环回中取两个值作为输入,

     <form id = "form" method="POST" name="myForm"  content = "application/json">
    <input id = "setrname"  placeholder="Router-Name" type="text" required />
    <input id = "setloopback" placeholder="Loop-Back" type="text" minlength="7" maxlength="15" size="15" pattern="^((\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.){3}(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$">
    <input value="Submit" class="formBtn" type="submit"">
    <input class="formBtn" type="reset" />
  </form>

Javascript代码

    var form = document.getElementById('form')

 form.addEventListener('submit',function(e){
     e.preventDefault()
     var rName = document.getElementById('setrname').value
     console.log(rName)
     var loop_back = document.getElementById('setloopback').value
     console.log(loop_back)
    var status1 =0;
    var status2 =0;
    var status3 =0;
    var status4 =0;
    var status5 =0;
    var final_status =0 ;
    var flag =0;
    $.post("http://localhost:8081/ping",{"loop_back":loop_back,"rName":rName,"final_status":final_status,"status1":status1,"status2":status2,"status3":status3,"status4":status4,"status5":status5,"flag":flag},function(data){
    console.log(data)}).done(function(){alert('Request done!');})
        .fail(function() { alert('failed, '); });
 })

@RequestMapping(method = RequestMethod.POST,value="/ping",consumes = "application/json")
    public void addData(@RequestBody PingData data) {
        pingdataservice.save(data);
    }

发送POST请求时Spring的输出

[io.javabrains.demo.ping.pingdata@6b3fbeba,io.javabrains.demo.ping.pingdata@343caa92,io.javabrains.demo.ping.pingdata@296453b0,io.javabrains.demo.ping.pingdata@48166a94,io.javabrains.demo.ping.pingdata@5ecad742,io.javabrains.demo.ping.pingdata@ff39e33,

在json.stringify（requestdata）中发送请求数据。会奏效的

ex: JSON.stringify({"loop_back":loop_back,"rName":rName})
