Question

我有以下json结构：

{
    "foo" : {
        "foo1" : {
            "txt" : "val",
            "txt1" : "val1",
            "txt2" : "val2",
        },
        "foo2" : {
            "txt" : "val",
            "txt1" : "val1",
            "txt2" : "val2",
        }
    },
    "bar" : {
        "bar1": {
            "txt" : "val",
            "txt1" : "val1",
            "txt2" : "val2",
        },
        "bar2": {
            "txt" : "val",
            "txt1" : "val1",
            "txt2" : "val2",
        }
    }
}

虽然我有以下pojo：

class Pojo {
  String txt;
  String txt1;
  String txt2;
}

我的resteasy方法看起来像：

@POST
@Produces({ MediaType.APPLICATION_JSON })
@Consumes({ MediaType.APPLICATION_JSON })
@Path("/foo")
public void bar(@QueryParam("jsonObj") Map<String,Map<String,Pojo>> jsonObj);

然而，在启动服务器时，我收到以下错误：

我浏览了documentation，对于复杂对象，它说使用StringConvertor，但不应该支持List，Map等简单类型...

Answer 1

而不是在Map＆gt;中获取JSON; jsonObj格式，您可以使用InputStream然后您可以处理输入流以从中获取对象。

resteasy @Consume json使用java.util.Map失败
