Examples for Chapter 6 - RESTful Java with JAX-RS 2.0 - page 284

Chapter 21. Examples for Chapter 6

In Chapter 3 , you saw a quick overview on how to write a simple JAX-RS service. You
might have noticed that we needed a lot of code to process incoming and outgoing XML
data. In Chapter 6 , you learned that all this handcoded marshalling code is unnecessary. JAX-
RS has a number of built-in content handlers that can do the processing for you. You also
learned that if these prepackaged providers do not meet your requirements, you can write
your own content handler.
There are two examples in this chapter. The first rewrites the ex03_1 example to use JAXB
instead of handcoded XML marshalling. The second example implements a custom content
handler that can send serialized Java objects over HTTP.

Example ex06_1: Using JAXB
This example shows how easy it is to use JAXB and JAX-RS to exchange XML documents
over HTTP. The com.restfully.shop.domain.Customer class is the first interesting piece
of the example.

src/main/java/com/restfully/shop/domain/Customer.java

@XmlRootElement ( name = "customer" )
public public class class Customer Customer {

private private int int id ;

private private String firstName ;

private private String lastName ;

private

private String street ;
private private String city ;

private private String state ;

private

private String zip ;
private

private String country ;

@XmlAttribute
public

public int int getId () {

return return id ;

}

public public void void setId ( int int id ) {

this this . id = id ;

}

@XmlElement ( name = "first-name" )
