JSON对象和Spring @RequestParam

Question

我在我的网站前端操作下面的JSON对象

<script>
window.campaign = {
    name: "test",
    budget: 20.00,
    type: 0,
    dynamic: false,
    geo_target: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27],
    time_target: {
        monday: ["00","00","00","00",1],
        tuesday: ["00","00","00","00",1],
        wednesday: ["00","00","00","00",1],
        thursday: ["00","00","00","00",1],
        friday: ["00","00","00","00",1],
        saturday: ["00","00","00","00",1],
        sunday: ["00","00","00","00",1]
    },

    setName: function(val) {
        this.name = val;
    },

    //some more setters go here
}
</script>

然后我使用AJAX将其发送到我的Spring应用程序

$.ajax({ type: "POST", url: submit_url, data: JSON.stringify(window.campaign) })
.done(function() { alert( "success" ); })
.fail(function() { alert( "error" ); });

现在问题是相应地映射@Controller中的所有变量

....
@RequestParam(value = "name", required = false, defaultValue = "") String name,
@RequestParam(value = "budget", required = false, defaultValue = "0") BigDecimal budget,
@RequestParam(value = "type", required = false, defaultValue = "0") int type,
@RequestParam(value = "dynamic", required = false, defaultValue = "false") boolean dynamic,
@RequestParam(value = "geo_target", required = false, defaultValue = "") int[] geoTargeting,
....

这一切都很好，但我不知道如何映射time_target

我尝试使用@RequestBody创建一个新的Model并对其进行映射

....
@RequestParam(value = "name", required = false, defaultValue = "") String name,
....
@RequestParam(value = "geo_target", required = false, defaultValue = "") int[] geoTargeting,    
@RequestBody TimeTarget timeTargeting
....

但没有成功。我使用http://www.jsonschema2pojo.org为我发送的整个对象创建了一个Class，但没有成功(仅供参考，它创建了两个类，一个用于timeTargeting，另一个用于其他所有内容)。

我真的很绝望。请帮助:)如果提供的代码还不够，我可以更新更多。
