Question

我是progrmming的新手，使用spring mvc框架开发spring MVC应用程序。我想通过使用带有2个映射实体的JSTL将数据列表到表中。

<c:forEach items="${empList}" var="emp">
<tr class="odd gradeX">
     <td>${emp.icode}</td>
     <td>${emp.employeeName}</td>
     //problem here
     //I want to get employee's phone num 
     <td>${emp.ph_number}</td>                                              
</tr>
</c:forEach>

这是我的实体的例子， 1）员工实体

@Entity
public class Employee implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long employeeId;
private String employeeName;

@OneToMany(mappedBy="employee" ,cascade={CascadeType.ALL})
private List<Phone>phones;

//method getter setter }

2）电话实体

@Entity
public class Phone implements Serializable{

@Id
@GeneratedValue(strategy = GenerationType.AUTO)

private long phoneId;
private String ph_number;

@ManyToOne
private Employee employee;
//method getter setter}

3）Enployee控制器

@Controller
public class EmployeeController {
@EJB(mappedName = "ejb:/EJB//EmployeeServiceBean!com.mfu.ejb.EmployeeService")
EmployeeService empServ;
@RequestMapping("/listEmp")
public ModelAndView listEmployee(HttpServletRequest request) {
    ModelAndView mv = new ModelAndView("ListEmp.jsp");

    List<Employee> empList;
    try {
        empList = empServ.getAllEmployee();
        mv.addObject("empList", empList);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return mv;
}
}

谢谢你，抱歉我的英语不好。希望它有所作为。
