我正在使用弹簧拼贴 2 进行通用布局。我想通过拼贴获取带有 id 的页面。当我打开我的页面进行编辑时，此链接包含带有 id 的路径，然后它在新页面中打开而不是通用布局。请帮助我

It's kind of hard to decipher what you are asking, but I'll give it a go. If you're talking about accountedit/<id> page, then I'm guessing this call is wrong:

@RequestMapping(value = "/accountedit/{accountid}", method = RequestMethod.GET)
public ModelAndView updateAccount(@PathVariable String accountid) {
    System.out.println("## HELLO UPDATE");
    return new ModelAndView("accountupdate", "account", accountService.getAccountDetails(accountid));
    //return new ModelAndView("accountupdate", accountService.getAccountDetails(accountid));
}

I'd try and change it to

@RequestMapping(value = "/accountedit/{accountid}", method = RequestMethod.GET)
public ModelAndView updateAccount(@PathVariable String accountid) {
    System.out.println("## HELLO UPDATE");
    return new ModelAndView("accountedit", "account", accountService.getAccountDetails(accountid));
}

I think you have problems as accountupdate is not a mapped tile.
