@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); } |
表单提交二
使用.serialize()方法 提交表单内容;
1、可以后台使用 request.getParamter("对应字段的name")获取参数;
2、也可以使用 Model mdel 的POJO接受。(name要一一对应起来)
- 格式:var data = $("#formID").serialize();
- 功能:将表单内容序列化成一个以&拼接的字符串,键值对的形式,name1=val1&name2=val2&,空格以%20替换。

如果想要接收User[]数组,只需要把saveUsers的参数类型改为@RequestBody User[] userArray就行了。
接收List<Map<String,Object>>集合参数:
