代码：
public ActionForward managerLogin(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
managerform managerForm = (managerform) form;
managerForm.setName(managerForm.getName());
managerForm.setPwd(managerForm.getPwd());
int ret = managerDAO.checkManager(managerForm);
System.out.print("验证结果ret的值:" + ret);
if (ret == 1) {
HttpSession session = request.getSession();
session.setAttribute("manager", managerForm.getName());
return mapping.findForward("managerLoginok");
} else {
request.setAttribute("error", "您输入的管理员名称或密码错误！");
return mapping.findForward("error");
}
}
private ActionForward managerQuery(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
String str = null;
request.setAttribute("managerQuery", managerDAO.query(str));
return mapping.findForward("managerQuery");
}
```
需要改的地方：
避免参数直接赋值：
```
ret == 1)
```
缺少注释
