To pretty print XML using the Jersey client in Java, you can customize the client's configuration to enable pretty printing. The Jersey client uses the org.glassfish.jersey.client.ClientConfig class to configure its behavior. By adding specific configuration properties, you can control the XML output format during the client request.

Here's how you can pretty print XML using the Jersey client:

  1. Add Dependency: Make sure you have the Jersey client library as a dependency in your project. You can use Maven to add the following dependency:

    xml
    <dependency> <groupId>org.glassfish.jersey.core</groupId> <artifactId>jersey-client</artifactId> <version>2.x</version> <!-- Replace with the desired version --> </dependency>
  2. Configure the Client: Create an instance of ClientConfig and set properties to enable pretty printing. In this case, we will use the property ClientProperties.PRETTY_PRINT_OUTPUT and set it to true.

    java
    import javax.ws.rs.client.Client; import javax.ws.rs.client.ClientBuilder; import org.glassfish.jersey.client.ClientConfig; import org.glassfish.jersey.client.ClientProperties; public class JerseyClientExample { public static void main(String[] args) { // Create a client configuration ClientConfig config = new ClientConfig(); config.property(ClientProperties.PRETTY_PRINT_OUTPUT, true); // Create the Jersey client with the configured properties Client client = ClientBuilder.newClient(config); // Perform your client requests here... } }
  3. Perform Client Request: Use the configured Client instance to perform your request. The XML response will be pretty printed.

    java
    import javax.ws.rs.client.Client; import javax.ws.rs.client.ClientBuilder; import org.glassfish.jersey.client.ClientConfig; import org.glassfish.jersey.client.ClientProperties; import javax.ws.rs.core.Response; public class JerseyClientExample { public static void main(String[] args) { // Create a client configuration ClientConfig config = new ClientConfig(); config.property(ClientProperties.PRETTY_PRINT_OUTPUT, true); // Create the Jersey client with the configured properties Client client = ClientBuilder.newClient(config); // Perform the client request Response response = client.target("https://api.example.com/data") .request() .get(); // Print the pretty printed XML response String xmlResponse = response.readEntity(String.class); System.out.println(xmlResponse); // Close the client and the response response.close(); client.close(); } }

By setting the ClientProperties.PRETTY_PRINT_OUTPUT property to true, the Jersey client will automatically pretty print the XML response during the client request. This configuration ensures that the XML output is human-readable and indented properly for better readability.
