Spring RestController如何同时接受JSON和XML？

Question

我有一个很好用的Spring控制器：

@RestController
@RequestMapping(value = "/widgets")
class WidgetController {
    @RequestMapping(method = RequestMethod.POST)
    WidgetResponse createWidget(@Valid @RequestBody Widget widget) {
        // ...
    }
}

{
  "name" : "Widget1",
  "type" : "spinning",
  "isFizz" : true
}

<widget name="Widget1">
  <type>spinning</type>
  <isFizz>false</isFizz>
</widget>

null

使用参数consumes注释@requestmapping

@RequestMapping(value = "/widgets",consumes={MediaType.APPLICATION_JSON_VALUE,MediaType.APPLICATION_XML_VALUE})
WidgetResponse createWidget(@Valid @RequestBody Widget widget){
///
{

参数consumes取MediaType数组
