Spring MVC将多个列表从控制器传递到jsp

Question

我有两个对象Employee和Department员工包含dept_id。我想要做的是在jsp页面的表格中显示Employee的内容。但不是显示dept_id我想显示dept_name从Department表。到目前为止，我有我的控制器方法：

public ModelAndView viewEmployee(HttpServletRequest request, 
      HttpServletResponse response) throws Exception { 

     List<Employee> employeeList = employeeService.getAllEmployee(); 
     List<Department> departmentList = new ArrayList<Department>(); 
     for (Employee e : employeeList) { 
      departmentList.add(departmentService.getDepartment(e.getDept_id())); 
     } 
     Map<String, Object> model = new HashMap<String, Object>(); 
     model.put("employee", employeeList); 
     model.put("department", departmentList); 

     return new ModelAndView("viewEmployee", "model", model); 
    } 

viewEmployee.jsp

<table border="1px" bordercolor="black" width=80% align="center"> 
       <tr> 
        <td>Name</td> 
        <td>Gender</td> 
        <td>Salary</td> 
        <td>Department</td> 
        <td>Action</td> 
       </tr> 
       <c:forEach items="${model.employeeList}" var="element"> 

        <tr> 
         <td><c:out value="${element.name}" /></td> 
         <td><c:out value="${element.gender}" /></td> 

         <td><c:out value="${element.salary}" /></td> 

         <td>display Department Name here </td> 

         <td><a 
          href="<c:url value="editEmployee.htm"> 
        <c:param name="emp_id" value="${element.id}"/> 
     </c:url> 
    ">Edit</a> 
          <a 
          href="<c:url value="deleteEmployee.htm"> 
        <c:param name="emp_id" value="${element.id}"/> 
     </c:url> 
    ">Delete</a> 

         </td> 
        </tr> 

       </c:forEach> 
      </table> 

任何帮助吗？我无法将地图内容显示到jsp页面。

Answer 1

应该<c:forEach items="${model.employee}" var="element">

而且部门应该是员工的属性，这样就可以使用${employee.department.name}
