今天遇见一个form需要两个button提交显示不同Controller的需求

一开始解决思路：

---

我有一个HTML页面的一个窗体和2个按钮的片段：

<form action="#" data-th-action="@{/action/edit}" data-th-object="${model}" method="post"><button type="submit" name="action" value="save">save</button><button type="submit" name="action" value="cancel">cancel</button>
</form>

以及控制器：

@RequestMapping(value="/edit", method=RequestMethod.POST)
public ModelAndView edit(@ModelAttribute SomeModel model, @RequestParam(value="action", required=true) String action) {if (action.equals("save")) {// do something here     }if (action.equals("cancel")) {// do another thing}return modelAndView;
}

后来网上查阅大牛的思路：

您可以使用params变量创建具有不同@RequestMappings的单独方法。

@RequestMapping(value="/edit", method=RequestMethod.POST, params="action=save")
public ModelAndView save() {}
@RequestMapping(value="/edit", method=RequestMethod.POST, params="action=cancel")
public ModelAndView cancel() {}

使用th：formactionon submit button这是工作在多少你有submit button和这也是usefull给予更多的链接到一个表单与不同的submit button

<form action="#"  class="form" th:action="@{'/publish-post/'+${post.id}}" method="post">
<input class="savebtn" type="submit" value="Save" th:formaction="'/save-post/'+${post.id}">
<input class="publish" type="submit" value="Publish Article">
</form>

---

对于多个提交按钮，下面的方法对我很有效。* 注意：th：取消按钮中的格式操作。*

<form action="#" th:action="@{/saveProducts}" th:object="${model}" method="post"><button type="submit" name="action" value="cancel" th:formaction="@{/cancelProducts}">CANCEL</button><button type="submit" name="action" value="save">SAVE</button>
</form>

对于控制器：

@RequestMapping(value="/saveProducts", method= RequestMethod.POST)public String save(@ModelAttribute SomeModel model) {*//Do something*}@RequestMapping(value="/cancelProducts", method=RequestMethod.POST)public String cancel(@ModelAttribute SomeModel model) {*//Do something*}
