假设我有这样的表格:
<form method="post" action="/create">
<input type="text" name="title.0" value="Curious George" />
<input type="text" name="author.0" value="H.A. Rey" />
<input type="text" name="date.0" value="2/23/1973" />
<input type="text" name="title.1" value="Code Complete" />
<input type="text" name="author.1" value="Steve McConnell" />
<input type="text" name="date.1" value="6/9/2004" />
<input type="text" name="title.2" value="The Two Towers" />
<input type="text" name="author.2" value="JRR Tolkien" />
<input type="text" name="date.2" value="6/1/2005" />
<input type="submit" />
</form>
如何从 Spring MVC 3.0 Controller 解析它?
最佳答案
name
属性不必是唯一的。所以:
<input type="text" name="title" value="Curious George" />
<input type="text" name="title" value="Code Complete" />
<input type="text" name="title" value="The Two Towers" />
然后
@RequestMapping("/create")
public void create(
@RequestParam("title") List<String> titles,
@RequestParam("author") List<String> authors, ..) {..}
应保留元素的顺序,根据 the spec :
The control names/values are listed in the order they appear in the document. The name is separated from the value by '=' and name/value pairs are separated from each other by '&'.
