java - Spring MVC @RequestMapping 不返回任何内容，只需关闭

Question

我正在开发一个收集信息的 JSP，提交后页面关闭，然后转到确认页面。我不需要确认页面。单击 JSP 上的“提交”后，我只想关闭窗口。 Controller 上的返回值需要一个值。我可以在那里放什么让它简单地结束？这是我的 Controller :

@Controller
//@SessionAttributes({"resultBoard", "filterBoard"})
public class NewEmployeeController {

    NewEmployeeService newEmpService;

    @Autowired
    public NewEmployeeController(NewEmployeeService service){
        this.newEmpService = service;
    }

    @RequestMapping(value = "NewEmpInput", method = RequestMethod.GET)
    public String promptEmployee(Model model)
    {
        //JSP can only reference 1 object, but need to reference many objects. So I put many classes inside EmployeeFormWrapper wrapper class.
        model.addAttribute("myForm", new EmployeeFormWrapper());
        return "NewEmpInput";
    }

    @RequestMapping(value = "NewEmpInput", method = RequestMethod.POST)
    public String newEmployee(@ModelAttribute("myForm") EmployeeFormWrapper myForm)
    {

        NewEmployeeVM employee = myForm.getEmployee();
        ClientVM client = myForm.getClient();
        ProjectVM project = myForm.getProject();
        System.out.println("Employee = " + employee.getFirstName() + " " + employee.getLastName());
        System.out.println("Client = " + client.getText());
        System.out.println("Project = " + project.getText());

        newEmpService.saveNewEmployee(employee);

        return "ConfirmNewEmp";
    }
}

更改了 java Controller 中的方法以返回 void。我将此脚本添加到我的 jsp 中:

<script type="text/javascript">
    function closeWindow() {
        window.close();
    }
</script>

并将我的 jsp 中表单的第一行更新为:

<form:form commandName="employee" modelAttribute="employee" onsubmit="closeWindow()">

我在jsp中的提交按钮保持不变:

<p>
    <input type="submit" value="Submit">
</p>

现在可以了。谢谢。
