You need a form and then submit the value to the controller ...
您需要一个表单，然后将值提交给控制器...
Something like :
就像是 ：
<form name="foo" action="/foo/bar" method="post">
<input name="fieldName" type="text" />
<input type="submit" value="Submit">
<form>
And then get it in your controller :
然后在你的控制器中获取它：
@Controller
@RequestMapping(value = "/foo")
public class AdminController {
@RequestMapping(value = "/bar")
public String testAction(@RequestParam String fieldName) {
// yourValue contain the value post from the html form
return "yourview";
}
}
