java - 在 spring mvc 中使用ajax将列表数据绑定(bind)到模型

Question

我有一个场景，我想使用 ajax 将数据绑定(bind)到 spring 中的模型类

模型类:EmployeeBean

private List<FamilyBean> familyDetails;
private String name;
//Getters and setters

FamilyBean 类位于此处:

private String memberId;
private String empUserId;
private String relationship;
private String memberName;
private String age;
private String occupation;
private String contact;
private String isIncludeMedIns;
private String modefiedBy;
private String modifiedOn;
//Getters and Setters

JSP:

<input type="text" name="familyDetails[0].relationship" value="A">
<input type="text" name="familyDetails[0].memberName" value="B">
 <input type="text" name="familyDetails[0].age" value="C">
  <input type="button" value="Previous" name="_target1" id="previous">

Ajax 调用:

$("#previous").click(function(){            
        $.ajax({                
            type: "POST",
            url:"saveTempEmployeeData",
            data:$("#formData").serialize(),//formData is id of the form                
            success:function (map) {                    
                //alert("SUCCESS");                                           
            },
            error:function (xhr) {
                //alert(xhr.statusText+" ERROR");
            }
        }); 
    });

Spring Controller :

@RequestMapping(value="/saveTempEmployeeData", method=RequestMethod.POST, headers="Accept=*")
public @ResponseBody void saveTempEmployeeData(HttpServletRequest request, HttpServletResponse response, @ModelAttribute("employeeBean")EmployeeBean employeeBean, ModelMap map) throws Exception{              

    userService.saveTempEmployeeData(employeeBean, pageNumber);

    try{
        System.out.println("In controller");

    }
    catch(Exception e){

    }
    response.setContentType("application/json");
    response.setCharacterEncoding("ISO-8859-1");
    response.getWriter().write(new Gson().toJson(map));

}

数据未绑定(bind)到 Controller 中的模型属性。

有什么办法吗？

注意:<input type="text" name="name" value="Sunny">

此数据正在绑定(bind)到模型。

我认为您应该在 JSP 中命名输入控件，如下所示:

<input type="text" name="employeeBean.familyDetails[0].relationship" value="A">
<input type="text" name="employeeBean.familyDetails[0].memberName" value="B">
<input type="text" name="employeeBean.familyDetails[0].age" value="C">

这样 Spring 就会知道它必须在 employeeBean 内填充 familyDetails。
