我正面临更新对象的prblm，因为当我试图在 updateApp 函数上显示我的对象id时，我得到0表示它不是 editApp 功能
上的相同对象控制器
@RequestMapping(value = { "/edtApp-{id}" }, method = RequestMethod.GET)
public String editApp(@PathVariable int id, ModelMap model) {
PIL_P_APPLCTN application = appService.findById(id);
logger.info("=========>"+application.getId()+" "+application.getAPPLCTN_CD());
List<PRM_CONTEXTE> cntxt = cntxtService.findAllOBJECTS();
model.addAttribute("cntxt", cntxt);
model.addAttribute("application", application);
model.addAttribute("edit", true);
model.addAttribute("loggedinuser", getFullName());
return "formApp";
}
@RequestMapping(value = { "/edtApp-{id}" }, method = RequestMethod.POST)
public String updateApp(@Valid @ModelAttribute("application") PIL_P_APPLCTN application, BindingResult result, ModelMap model,
@PathVariable int id) {
logger.info("====**=====>"+application.getId()+" "+application.getAPPLCTN_CD());
logger.info("====**=====>"+application.getId()+" "+application.getAPPLCTN_DS());
logger.info("====**=====>"+application.getId()+" "+application.getAPPLCTN_ID());
logger.info("====**=====>"+application.getId()+" "+application.getDECLG_IDNTFNT_NU());
logger.info("====**=====>"+application.getId()+" "+application.getVersion());
logger.info("====**=====>"+application.getId()+" "+application.getActive());
List<PRM_CONTEXTE> cntxt = cntxtService.findAllOBJECTS();
if (result.hasErrors()) {
model.addAttribute("cntxt", cntxt);
return "formApp";
}
appService.updateOBJECT(application);
return "redirect:/appli";
}

感谢任何建议..
答案 0 :(得分：0)
通过更改pathVariable的名称来解决此问题，因为它与ID相同，并且在我的实体中添加了 set for id
@RequestMapping(value = { "/edtApp-{i}" }, method = RequestMethod.GET)
public String editApp(@PathVariable int i, ModelMap model) {
//....
}
@RequestMapping(value = { "/edtApp-{i}" }, method = RequestMethod.POST)
public String updateApp(@Valid @ModelAttribute("application") {
//....
}
