1.Java代码
@RequestMapping("/sq-condition/{type}")
public ModelAndView sqCondition(@PathVariable(value="type") int type){
Map<String,Object> validateMap=validateSession(sessionTimeOut);
if(validateMap.get("SESSION_VALIDATED").toString().equals("false")){
return new ModelAndView(sessionTimeOut);
}
ModelAndView mv=new ModelAndView("redirect:/pda/stock/sq-condition.html");
mv.addObject("type", type);
return mv;
}
注：根据类型控制显示不同条件。
