Jakarta JSON Processing with Japanese Joy

Joy is a Japanese implementation of the Jakarta JSON Processing (JSON-P) API.

To use it in a standalone Maven project, declare the following dependencies:

<dependency>
    <groupId>jakarta.json</groupId>
    <artifactId>jakarta.json-api</artifactId>
    <version>2.0.0</version>
</dependency>
<dependency>
    <groupId>org.leadpony.joy</groupId>
    <artifactId>joy-classic</artifactId>
    <version>2.1.0</version>
</dependency>

Now you can start to process JSON, just using the Jakarta EE APIs:

import java.io.StringReader;
import org.junit.jupiter.api.Test;
import jakarta.json.Json;


public class JsonpWithJoyTest {

    @Test
    public void parseJSON() {
        var expected = "joy";
        var json = """
                {"hello":"%s"}
                """.formatted(expected);
                
        try (var stringReader = new StringReader(json)){
            var jsonObject = Json.createReader(stringReader).readObject();
            var actual = jsonObject.getString("hello");
            assertEquals(expected, actual);
        }
        
    }
}
