@RequestMapping (value = "/save" , method = RequestMethod.POST) public GeneralResponse save( @RequestBody @Valid MemberInsertDetail member, BindingResult bindingResult) throws JsonProcessingException { if (bindingResult.hasErrors()) { throw new ErrParamException(); } boolean flag = false ; flag = memberService.save(member); } |
表單提交二
使用.serialize()方法 提交表單內容;
1、可以后臺使用 request.getParamter("對應字段的name")獲取參數;
2、也可以使用 Model mdel 的POJO接受。(name要一一對應起來)
- 格式:var data = $("#formID").serialize();
- 功能:將表單內容序列化成一個以&拼接的字符串,鍵值對的形式,name1=val1&name2=val2&,空格以%20替換。

@RequestMapping ( "/addEmployees" ) @ResponseBody public Result<Integer> addEmployees(HttpServletRequest request) { String phone = request.getParameter( "phone" ); String password = request.getParameter( "password" ); String username = request.getParameter( "username" ); 身份單checkbox接收。如果是復選框多個checkbox,則用數組String[] 接收。 String checkbox = request.getParameter( "checkbox" ); } |

如果想要接收User[]數組,只需要把saveUsers的參數類型改為@RequestBody User[] userArray就行了。
接收List<Map<String,Object>>集合參數:
