如何使用Jackson将ObjectNode作为父对象添加到子ObjectNode

Question

我想在嵌套结构中添加2个节点。第一个是初始状态

INITIAL 
{
"type" : "type",
"features" : [ {
"properties" : {
"staticText" : "1",
"assets" : {
"metaData" : {
"someMetaData"
}
}
}
} ],
}

我想添加"合并"one_answers";node"对象节点如下所示。那我就选下面这个了。

DESIRED
{
"type" : "type",
"features" : [ {
"merge" : {
"properties" : {
"staticText" : "1",
"assets" : {
"node": {
"metaData" : {
"someMetaData"
}
}
}
} 
}
} ],
}

我想把空节点("jsonNodes"下面的代码,但没有成功。我如何在第二个嵌套节点声明?

root.with("merge").set("properties",jsonNodes);

反序列化

Josson josson = Josson.fromJsonString(
"{" +
"  "type" : "type"," +
"  "features" : [ {" +
"    "properties" : {" +
"      "staticText" : "1"," +
"      "assets" : {" +
"        "metaData" : {" +
"          "someMetaData" : "xxx"" +
"        }" +
"      }" +
"    }" +
"  } ]" +
"}");

转换

JsonNode node = josson.getNode(
"field(features" +
"  .map(merge" +
"    :field(properties" +
"      .field(assets" +
"        .map(node" +
"          :field(metaData)" +
"        )" +
"      )" +
"    )" +
"  )" +
")");
System.out.println(node.toPrettyString());

输出

{
"type" : "type",
"features" : [ {
"merge" : {
"properties" : {
"staticText" : "1",
"assets" : {
"node" : {
"metaData" : {
"someMetaData" : "xxx"
}
}
}
}
}
} ]
}
