ajax不能跳转页面，需要传递Message来决定结果

@RequestMapping(value = "/updateEmployeeIntro", method = RequestMethod.POST)
@ResponseBody
public Message updateEmployeeIntroById(HttpSession session, EmployeeIntroVO employeeIntroVo) {
Message msg = new Message();
EmployeeByCodeAndPwdVO employee = (EmployeeByCodeAndPwdVO) session.getAttribute("employee");
employeeIntroVo.setEmployeeId(employee.getId());
employeeIntroVo.setUpdator(employee.getId());
employeeIntroVo.setUpdateTime(new Date());
int retNumber = employeeBaseService.updateEmployeeDetail(employeeIntroVo);
if (retNumber > 0) {
msg.setResult(true);
} else {
msg.setResult(false);
}
return msg;

}
