How to fetch multifield item's content from the below JSON in junits

[priyak]

Can anyone help me with the below query?

In the below JSON, how can I fetch desc and title from the multiFieldContent ?? with the help of JSONArray we can achieve it, but since its deprecated.. please provide any suggestions.

{
"jcr:primaryType": "nt:unstructured",
"textLabel": "Text",
"multiFieldContent": {
"jcr:primaryType": "nt:unstructured",
"item0": {
"jcr:primaryType": "nt:unstructured",
"desc": "desc1",
"title": "title1"
},
"item1": {
"jcr:primaryType": "nt:unstructured",
"desc": "desc2",
"title": "title2"
}
}
}

Hi,

We can use Gson, however you can check here how to write junit test for multifield https://medium.com/@veena.vikraman19/aem-junit-for-simple-aem-component-with-multifield-2326f61c8982  

import com.google.gson.Gson;
import com.google.gson.JsonObject;

String str="{\n"

+ " \"jcr:primaryType\": \"nt:unstructured\",\n"

+ " \"textLabel\": \"Text\",\n"

+ " \"multiFieldContent\": {\n"

+ " \"jcr:primaryType\": \"nt:unstructured\",\n"

+ " \"item0\": {\n"

+ " \"jcr:primaryType\": \"nt:unstructured\",\n"

+ " \"desc\": \"desc1\",\n"

+ " \"title\": \"title1\"\n"

+ " },\n"

+ " \"item1\": {\n"

+ " \"jcr:primaryType\": \"nt:unstructured\",\n"

+ " \"desc\": \"desc2\",\n"

+ " \"title\": \"title2\"\n"

+ " }\n"

+ " }\n"

+ "}";

JsonObject json=new Gson().fromJson(str, JsonObject.class);

JsonObject multiFieldContent=json.get("multiFieldContent").getAsJsonObject();

String desc1=multiFieldContent.get("item0").getAsJsonObject().get("desc").getAsString();

String desc2=multiFieldContent.get("item1").getAsJsonObject().get("desc").getAsString();

Thanks,

Hi, 

If you need this to be just for your JUnit, you could use any other JSON parser as a dependency to do the job. For example, you can use the Jackson library to represent the JSON data and get those values. Please check this: https://www.baeldung.com/java-jsonnode-get-keys 

For example:

- Include the dependency in your pom.xml

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.13.1</version>
    <scope>test</scope>
</dependency>

- Try something like this

//Your JSON string representation
String jsonString = "{}";
// Create ObjectMapper instance
ObjectMapper mapper = new ObjectMapper();

// Parse JSON string to JsonNode
JsonNode rootNode = mapper.readTree(jsonString);

// Navigate to the multiFieldContent node
JsonNode multiFieldContentNode = rootNode.path("multiFieldContent");

// Iterate over items in multiFieldContent
multiFieldContentNode.fields().forEachRemaining(entry -> {
    JsonNode itemNode = entry.getValue();
    String title = itemNode.path("title").asText();
    String desc = itemNode.path("desc").asText();
    System.out.println("Title: " + title + ", Description: " + desc);
});

Hope this helps.
