Examples for Chapter 4 - RESTful Java with JAX-RS 2.0 - page 270

The @PATCH annotation is used on the patchCustomer() method. The implementation of this
method simply delegates to the original updateCustomer() method.

The Client Code

The client code for ex04_1 is pretty straightforward and similar to ex03_1 . Let's look at some
initial minor changes we've made:
src/test/java/com/restfully/shop/test/PatchTest.java

package package com . restfully . shop . test ;

import import org.junit.AfterClass org.junit.AfterClass ;

import import org.junit.BeforeClass org.junit.BeforeClass ;

import import org.junit.Test org.junit.Test ;

import import javax.ws.rs.client.Client javax.ws.rs.client.Client ;

import import javax.ws.rs.client.ClientBuilder javax.ws.rs.client.ClientBuilder ;

import import javax.ws.rs.client.Entity javax.ws.rs.client.Entity ;

import import javax.ws.rs.core.Response javax.ws.rs.core.Response ;

public class class PatchTest PatchTest

{

private private static static Client client ;

@BeforeClass
public

public static static void void initClient ()

{

client = ClientBuilder . newClient ();

}

@AfterClass
public public static static void void closeClient ()

{

client . close ();

}

First, we initialize our Client object within a JUNit @BeforeClass block. Any static meth-
od you annotate with @BeforeClass in JUnit will be executed once before all @Test meth-
ods are executed. So, in the initClient() method we initialize an instance of Client . Stat-
