JSP中List中的$ {employee.id}抛出java.lang.NumberFormat

Question

我有一个JSP页面，当List<Employee>从下面的方法中显示时，它可以正常工作<c:forEach>。

@RequestMapping(value = { "getAllEmployees", "/" })

public ModelAndView getAllEmployees() {

    // logger.info("Getting the all Employees.");

    List<Employee> employeeList = employeeService.getAllEmployees();

    return new ModelAndView("employeeList", "employeeList", employeeList);

}

List<Employee>从下面的方法显示时，同一JSP会引发异常。

@RequestMapping("searchEmployee")

public ModelAndView searchEmployee(@RequestParam("searchName") String searchName) {

    // logger.info("Searching the Employee. Employee Names: " + searchName);

    List<Employee> employeeList = employeeService.getAllEmployees(searchName);

    System.err.println("Employee count = "+employeeList.size());

    return new ModelAndView("employeeList", "employeeList", employeeList);

}

这是堆栈跟踪：

java.lang.NumberFormatException: For input string: "id"

    java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)

这是怎么引起的，我该如何解决？
