我有 Controller ，通过它导航到 home.jsp在 home .jsp 中有两个按钮 FindEmployeeByid FindEmployeeByName现在，当我点击 FindEmployeeByid 时，新的弹出窗口已打开，但在弹出窗口中我收到此消息 The requested resource (/EmployeeWebSpring/search/Search.jsp) is not available. ，因为在 Search.jsp 中我使用了 spring 的表单标签，所以它无法获取模型对象，所以请告诉我如何执行此操作以打开一个输入字段处于事件状态的弹出窗口，以便我可以提交数据并执行一些操作在那个数据上

这是我的 Controller 

    package com.nousinfo.tutorial.controllers;

import java.util.List;

import org.springframework.stereotype.Controller;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import com.nousinfo.tutorial.model.EmployeeForm;
import com.nousinfo.tutorial.service.impl.EmployeeServiceImpl;
import com.nousinfo.tutorial.service.model.EmployeeBO;

@Controller
@RequestMapping("/search")
public class SearchEmployeeController {

    private EmployeeServiceImpl employeeServiceImpl;

    public void setEmployeeServiceImpl(EmployeeServiceImpl employeeServiceImpl) {
        this.employeeServiceImpl = employeeServiceImpl;
    }



    @RequestMapping(value = "/searchspring", method = RequestMethod.GET)
    public String view(@Validated EmployeeForm employeeForm)
            throws Exception {
    return "home";
    }


    @RequestMapping(value = "/employeeNo", method = RequestMethod.POST)
    public ModelAndView searchByEmpNo(
            @ModelAttribute("employeeForm") EmployeeForm employeeForm)
            throws Exception {
        ModelAndView model = new ModelAndView();
        model.addObject("employeeForm", employeeForm);
        Long i = Long.parseLong(employeeForm.getEmployeeNumber());

        EmployeeBO employeeBO = employeeServiceImpl.getEmployee(i);
        System.out.println(employeeBO);
        model.addObject("employeeBO", employeeBO);

        model.setViewName("EmployeeDetail");
        return model;
    }

    @RequestMapping(value = "/empByName", method = RequestMethod.POST)
    public ModelAndView searchByEmployeeName(
            @ModelAttribute("employeeForm") EmployeeForm employeeForm) {
        ModelAndView model = new ModelAndView();
        model.addObject("employeeForm", employeeForm);
        List<EmployeeBO> employeeBOs = employeeServiceImpl
                .findEmployees(employeeForm.getFirstName());
        model.addObject("listEmployeeBO", employeeBOs);
        model.setViewName("EmployeeList");
        return model;

    }

    @RequestMapping(value = "/empByDeptId", method = RequestMethod.POST)
    public ModelAndView searchByDeptId(
            @ModelAttribute("employeeForm") EmployeeForm employeeForm) {
        ModelAndView model = new ModelAndView();
        model.addObject("employeeForm", employeeForm);
        List<EmployeeBO> employeeBOs = employeeServiceImpl
                .getAllEmployeeByDeptid(employeeForm.getDepartmentId());
        model.addObject("listEmployeeBO", employeeBOs);
        model.setViewName("EmployeeList");

        return model;

    }

}

最佳答案

您可以在java脚本中执行以下操作并运行您的java脚本函数，因为您的函数运行它将控制权交给 Controller ，您可以提供jsp View 或任何 View 

<script>
    function popup() {
        window.open("../popup/searchspring", 'window', 'width=200,height=100');
    }
</script>

在 Controller 中你必须做这样的事情，它将你的请求导航到所需的页面，因为在 spring Controller 中决定 View 页面的导航 
 @RequestMapping(value = "/searchspring", method = RequestMethod.GET)
    public String view(Model model) throws Exception {
        EmployeeBO employeeBO = new EmployeeBO();
        model.addAttribute("employeeBO", employeeBO);
        return "EmployeeForm";
    }
