这段代码的时序图怎末画// 添加 @RequestMapping("/debook/add.html") public String addDebookHtml(Model model, HttpSession session) { List<Category> categoryList = categoryService.selectAll(); model.addAttribute("categoryList", categoryList); return "/admin/debook_add"; } @ResponseBody @RequestMapping("/debook/add") public Map<String, Object> addDebook(@RequestBody Debook debook, HttpSession session) { User user = (User) session.getAttribute(WebConstant.SESSION_KEY_USER); debook.setUserId(user.getId()); debook.setUsername(user.getUsername()); debook.setDebookTime(new Date()); debookService.insertSelective(debook); return new ResponseBean().getResponseMap(); }

以下是该段代码的简单时序图:
```
客户端 服务器
| |
| GET /debook/add.html HTTP/1.1 |
| Host: example.com |
| ... |
| |
| HTTP/1.1 200 OK |
| Content-Type: text/html |
| ... |
| <HTML> |
| ... |
| <form action="/debook/add"> |
| ... |
| |
| POST /debook/add HTTP/1.1 |
| Host: example.com |
| Content-Type: application/json |
| ... |
| {"name": "book1", |
| "category": "fiction", |
| ...} |
| |
| HTTP/1.1 200 OK |
| Content-Type: application/json|
| ... |
| {"code": 0, |
| "message": "success", |
| ...} |
| |
```
在客户端发送GET请求时,服务器会返回一个HTML表单,其中包含了所有的Category对象列表。当用户填好表单后,点击提交按钮,客户端会发送一个POST请求,将Debook对象的信息以JSON格式发送给服务器。服务器会在接收到请求后,从session中获取当前用户信息,并将该信息和Debook对象的其他信息一起设置到Debook对象中,最后通过调用debookService的insertSelective方法向数据库中添加Debook对象。最终,服务器会返回一个包含操作结果的JSON格式的响应。
