我有一個JSP頁面，當List從下面的方法中顯示時，它可以正常工作。

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

public ModelAndView getAllEmployees() {

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

List employeeList = employeeService.getAllEmployees();

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

}

List從下面的方法顯示時，同一JSP會引發異常。

@RequestMapping("searchEmployee")

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

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

List employeeList = employeeService.getAllEmployees(searchName);

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

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

}

這是堆棧跟蹤：

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

java.lang.Integer.parseInt(Integer.java:492)

org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)

這是怎么引起的，我該如何解決？
