REST API 插件 - 使用正文而不是查询字符串作为参数

and it creates me a receipt with the new body and title passed in.

这不起作用:

POST /receipt/
{
  "body": "new_body",
  "title": "new title"
}

这里有一些代码:

struts.xml:

    <constant name="struts.convention.default.parent.package" value="receipto"/>
    <constant name="struts.convention.package.locators" value="controllers,actions"/>
</struts>

ReceiptController.java:

public class ReceiptController implements ModelDriven<Object> {

    private ReceiptManager receiptManager = new ReceiptManager();
    private String id;
    private Receipt model = new Receipt();
    private Collection list;

    public Object getModel()
    {
        return (list==null ? model : list);
    }

    public HttpHeaders create()
    {
        receiptManager.save(model);
        return new DefaultHttpHeaders("create");
    }


    public HttpHeaders show()
    {
        model = receiptManager.find(id);
        return new DefaultHttpHeaders("show");
    }

    public HttpHeaders update()
    {
        receiptManager.save(model);
        return new DefaultHttpHeaders("update");
    }

    public HttpHeaders destroy()
    {
        model = receiptManager.destroy(id);
        return new DefaultHttpHeaders("destroy");
    }

    public HttpHeaders index()
    {
        list = receiptManager.list();
        return new DefaultHttpHeaders("index").disableCaching();
    }

    public String getId()
    {
        return id;
    }

    public void setId(String id)
    {
        this.id = id;
    }
}

它应该像我想要的那样工作，还是插件就是这样工作的?
