我有以下objectNode:
{
"type": "FeatureCollection",
"features": [
{"type":"Feature",
"properties":{
"pro1":"value1",
"pro2":"value2"
},
"geometry":{
"type":"Polygon",
"coordinates":[[[3.22998,48.312428],[3.22998,48.719961],[3.405762,48.719961],[3.405762,48.312428],[3.22998,48.312428]]]
}
}
]
}
基本上我想从属性中删除所有元素并获得类似的内容:
"properties":{}
我尝试过使用以下内容,但它会删除所有内容:
bufferPolygon.setObject(((ObjectNode)bufferIteration).with("properties").removeAll().toString());
答案 0 :(得分:0)
基本上我想删除
properties
中的所有元素并得到类似的内容:"properties":{}
以下内容可为您提供所需的结果:
JsonNode tree = mapper.readTree(json);
for (JsonNode feature : tree.get("features")) {
((ObjectNode) feature).set("properties", mapper.createObjectNode());
}
String updatedJson = mapper.writeValueAsString(tree);
