The JSON format is commonly used in RESTful web services to exchange messages. In this section, we will discuss how the Java API or JSON processing is used in a RESTful web service. First, add the RESTful web service dependency to pom.xml:
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0</version>
</dependency>Create a sample REST web service to test the JSON API. Create a resource class JsonResource annotated with @PATH to identify the URI path. Here's how we accomplish this:
package org.json;
import java.io.StringReader;
import javax.ws.rs.GET;
import javax.ws.rs.Produces;
import javax.ws.rs.Path;
import javax.json.*;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
@Path("jaxrs")
public class JsonResource {
}To package the resource class, create a class...
