Given a JSON like:
{
"a":1,
"b":2,
"c":3,
"d":4,
"e":5
}
How can I select out b, d and e to get the following JSON?
{
"b":2,
"d":4,
"e":5
}
I want a JSON object and NOT only 2, 4 and 5 values?
This is what I'm trying with and failing:
$.[b,d,e]
JSONPath is not suitable for what you are trying to achieve: JSONPath is designed to select values and not key-value pairs. What you want could be achieved with Jackson or any JSON parser for Java.
If you want to go for Jackson here's the code that will do the trick:
String json = "{\"a\":1,\"b\":2,\"c\":3,\"d\":4,\"e\":5}";
ObjectMapper mapper = new ObjectMapper();
JsonNode tree = mapper.readTree(json);
ObjectNode node = mapper.createObjectNode();
node.set("b", tree.get("b"));
node.set("d", tree.get("d"));
node.set("e", tree.get("e"));
String result = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(node);
Elements must be in single quotes.
$.['b','d','e']
Works fine for JsonPath from com.jayway.jsonpath:json-path:2.4.0
Your json path is correct, while json it self is not. It should be:
{
"a":1,
"b":2,
"c":3,
"d":4,
"e":5
}
BTW there is good online testing resources for these purposes: http://jsonpath.com/
You need to modify your JSON to (as said by Andremoniy)
{
"a":1,
"b":2,
"c":3,
"d":4,
"e":5
}
and to select b,d,e use this
$.b,d,e
