 # Common ReST Client Library

+
+### Spring Framework
+
+#### Single Client
+
+If you will only be declaring a single client in your Spring context, this is easy.  You will just need two things.  First, inject the single client into any of your Spring beans.  You may do inject it into more than one.  An example is below:
+
+```java
+@Component
+public class ... {
+    @Autowired
+    @Qualifier("client.cxf")  // may be optional
+    private Client client;
+}
+```
+
+Next, you need to configure that client.  You can do that by providing a single implementation of the `ClientConfiguration` (or `ClientCxfConfiguration`) interface.
+
+```java
+@Configuration
+public class ... implements ClientCxfConfiguration {
+    ...
+}
+```
+
+For Jersey implementations, just use `client.jersey` and `ClientJerseyConfiguration`.  If you want to provide one of each, then follow the instructions for multiple clients below.
+
+#### Multiple Clients
+
+If you will or may have multiple clients in your Spring context, there is an extra step.  You will still need to define a `ClientConfiguration` for each.  On top of that, you will need to create specialized implementations of each client.  That special implementation will reference the configuration directly.  An example is below.
+
+```java
+@Component("my.client")
+public class MyClient extends ClientCxfImpl {
+    @Autowired
+    public MyClient(MyClientConfiguration config) {
+        super(config);
+    }
+}
+```
+
+You can then inject your client(s) into your Spring beans.  Like the example below:
+
+```java
+@Component
+public class ... {
+    @Autowired
+    private MyClient client;
+
+    @PostConstruct
+    public void init() {
+        MyJaxRsApi api = this.client.getApi(MyJaxRsApi.class);
+    }
+}
+
+### POJO
+
+You do not have to use the Spring framework to use these classes.  You can instantiate them directly.  But you wil still need to create a `ClientConfiguration` as mentioned above.
+
+```java
+MyClientConfiguration config = new MyClientConfiguration();
+...
+ClientCxfImpl client = new ClientCxfImpl(config);
+MyJaxRsApi api = client.getApi(MyJaxRsApi.class);
+```
