使用Java Spring接收POST数据 [英] Receiving POST data with Java Spring

问题描述

我试图捕获一个使用以下代码发布到我的Java控制器中的数组:

I'm trying to catch an array that has been posted to my Java Controller with the code shown below:

@RequestMapping(method=RequestMethod.POST, value="/json/foo.json")
public @ResponseBody Object foo(List<Integer> fooIds)
{
    for (Integer id : fooIds)
    {
         fooService.delete(id);
    }
    return null;
}

但是我仍然出现以下错误:

However I keep getting the following error:

Could not instantiate bean class [java.util.List]: Specified class is an interface

我要发布的数组的设置如下(在PHP中):

The array I am posting is setup as follows (in PHP):

$array = array(
    "fooIds[0]" => 1,
    "fooIds[1]" => 2,
    "fooIds[2]" => 3,
    "fooIds[3]" => 4,
    "fooIds[4]" => 5,
);

我最初尝试过:

$array = array(1,2,3,4,5);

但是那也不起作用.

推荐答案

我可以使用以下代码:

@RequestMapping(method=RequestMethod.POST, value="/json/foo.json")
public @ResponseBody Object foo(@RequestParam("ids") int[] fooIds)
{
    for (Integer id : fooIds)
    {
        fooService.delete(id);
    }
    return null;
}

然后按如下所示设置阵列:

The array is then setup like this:

$array = array(
    'fooIds' => '1,2,3,4,5',
);
