JsonParserNotationParser

Example

Test Payload

{
  "friends": [
    {
      "id": 0,
      "name": "Santiago Mcmillan"
    },
    {
      "id": 1,
      "name": "Graham Zimmerman"
    },
    {
      "id": 2,
      "name": "Tabatha Garrison"
    }
  ]
}

Concept

parser.get("friends[*].name") -> ["Santiago Mcmillan", "Graham Zimmerman", "Tabatha Garrison"]

Prepare

String payload = readPayload();
ObjectMapper mapper = new ObjectMapper()
JsonNodeParser parser = new JsonNodeParser(mapper.readValue(payload, JsonNode.class));

Basic Usage

Assert.assertEquals(1, parser.get("friends[0].id").size());
Assert.assertEquals(1, parser.get("friends[1].id").size());
Assert.assertEquals(1, parser.get("friends[2].id").size());

Assert.assertEquals("0", parser.get("friends[0].id").get(0));
Assert.assertEquals("1", parser.get("friends[1].id").get(0));
Assert.assertEquals("2", parser.get("friends[2].id").get(0));

Assert.assertEquals(1, parser.get("friends[0].name").size());
Assert.assertEquals(1, parser.get("friends[1].name").size());
Assert.assertEquals(1, parser.get("friends[2].name").size());

Assert.assertEquals("Santiago Mcmillan", parser.get("friends[0].name").get(0));
Assert.assertEquals("Graham Zimmerman", parser.get("friends[1].name").get(0));
Assert.assertEquals("Tabatha Garrison", parser.get("friends[2].name").get(0));

Wildcard

Assert.assertEquals(3, parser.get("friends[*].id").size());
Assert.assertEquals(3, parser.get("friends[*].name").size());

Assert.assertEquals("Santiago Mcmillan", parser.get("friends[*].name").get(0));
Assert.assertEquals("Graham Zimmerman", parser.get("friends[*].name").get(1));
Assert.assertEquals("Tabatha Garrison", parser.get("friends[*].name").get(2));

Fail Case

Assert.assertEquals(0, parser.get("friends[0].xxx").size());
Assert.assertEquals(0, parser.get("friends[3].name").size());
Assert.assertEquals(0, parser.get("xxx").size());
