Java 如何通过单击控制器不同的同一JSP页面的两个不同按钮来开发两个调用ajax?

Java 如何通过单击控制器不同的同一JSP页面的两个不同按钮来开发两个调用ajax?,java,ajax,jsp,spring-mvc,Java,Ajax,Jsp,Spring Mvc,我正在春季开发一份员工登记表。我使用了两个ajax调用,一个用于员工信息,另一个用于上传e文件(图像),并将它们存储在单个jsp页面和单个控制器中的特定文件夹中。这是我的jsp页面: function onuploadCall(){ var file = $('[name="file"]'); console.log(file); var filename = $.trim(file.val()); console.log(filename); //va

我正在春季开发一份员工登记表。我使用了两个ajax调用,一个用于员工信息,另一个用于上传e文件(图像),并将它们存储在单个jsp页面和单个控制器中的特定文件夹中。这是我的jsp页面:

    var file = $('[name="file"]');
    console.log(file);
   var filename = $.trim(file.val());
   console.log(filename);
     //var imgContainer = $('#imgContainer');

    var formData = new FormData();
    formData.append('file', jQuery('input[type=file]')[0].files[0]);

    $.ajax({
        url: "http://localhost:8080/EmployeeRegistrationForm/echofile",
