作用:从一个@RequestMapping 中存储的数据传到另一个 @RequestMapping 中
使用手段: RedirectAttributes和@ModelAttribute
一个栗子:
@RequiresPermissions("quota:quotaSystem:edit")
@RequestMapping(value = "delete")
public String delete(QuotaSystem quotaSystem, RedirectAttributes redirectAttributes) {
//使用addFlashAttribute来设置重定向时需要传递的参数。
redirectAttributes.addFlashAttribute("myflag",quotaSystem.getQuotaSystemFlag()); //需要存储字段
quotaSystemService.delete(quotaSystem);
addMessage(redirectAttributes, "删除成功");
return "redirect:"+Global.getAdminPath()+"/quota/quotaSystem/deletelist";
}
@RequiresPermissions("quota:quotaSystem:view")
@RequestMapping(value = "deletelist")
//要重定向的方法,使用@ModelAttribute注解将参数拿到
public String deletelist(@ModelAttribute("myflag") String myflag ,Model model,QuotaSystem quotaSystem, HttpServletRequest request, HttpServletResponse response) {
quotaSystem.setQuotaSystemFlag(myflag);
Page<QuotaSystem> page = quotaSystemService.findPage(new Page<QuotaSystem>(request, response), quotaSystem);
model.addAttribute("page", page);
model.addAttribute("quotaSystemFlag", quotaSystem.getQuotaSystemFlag());
return "modules/quota/quotaSystemList";
}
