在mvc中将编辑和创建post方法合并为1

@Controller
@RequestMapping("/post")
public class PostController {

    @RequestMapping(value = "/save", method = RequestMethod.POST)
    public String savePost(@RequestParam("operation") String operation, @ModelAttribute("post") Post post) {
        if ("edit".equals(operation)) {
            // 执行编辑操作的逻辑
            // ...
        } else if ("create".equals(operation)) {
            // 执行创建操作的逻辑
            // ...
        }
        return "redirect:/post/list";
    }
}
