Maven Dependency

...

For injecting proxies via a spring context, use the jaxrs:client element like:

  <jaxrs:client id="restClient"
         address="http://localhost:${testutil.ports.BookServerRestSoap}/test/services/rest"
         serviceClass="org.apache.cxf.systest.jaxrs.BookStoreJaxrsJaxws"
         inheritHeaders="true">
         <jaxrs:headers>
             <entry key="Accept" value="text/xml"/>
         </jaxrs:headers>
  </jaxrs:client>  

See this bean for a full example of how jaxrs:client can be used to inject a proxy. Note that WebClient can also be injected as a jaxrs:client.

Asynchronous proxy invocations

...

Proxy sub-resource methods returning Objects can not be invoked. Prefer to have sub-resource methods returning typed classes: interfaces, abstract classes or concrete implementations. 

Working with user models

Proxies can be created with the external user model being applied to a proxy class, for example:

...

The above code will send requests like "GET http://books/1", "GET http://books/2", etc.

If the request URI can be parameterized then you may want to use the following code:

...

<bean id="myJsonProvider" 
class="org.apache.cxf.jaxrs.provider.JSONProvider" > 
        <property name="supportUnwrapped" value="true" /> 
        <property name="wrapperName" value="nodeName" /> 
    </bean> 

<util:list id="webClientProviders"> 
    <ref bean="myJsonProvider"/> 
</util:list> 

<bean id="myWebClient" class="org.apache.cxf.jaxrs.client.WebClient" 
factory-method="create"> 
        <constructor-arg type="java.lang.String" 
value="http://some.base.url.that.responds/" /> 
        <constructor-arg ref="webClientProviders" /> 
</bean> 

...

<jaxrs:client id="webClient"
         addressaddress="https://localhost:${port}/services/rest"
         serviceClass="org.apache.cxf.jaxrs.client.WebClient">
         <jaxrs:headers>
             <entry key="Accept" value="text/xml"/>
         </jaxrs:headers>
  </jaxrs:client>

The only limitation of using this option is that some of jaxrs:client attributes ("inheritHeaders", "modelRef") and elements ("model") are not really applicable to WebClient.

Clients and HTTP(s)

The default HttpClientHTTPConduit conduit by default supports the following HTTPS protocols: TLSv1, TLSv1.1, TLSv1.2, TLSv1.3. Since Apache CXF 4.0.4 / 3.6.3 release, the default HttpClientHTTPConduit respects https.protocols system property (see please https://blogs.oracle.com/java/post/diagnosing-tls-ssl-and-https) and if set, would use the provided protocols. This behavior could be turned off by setting https.protocols.ignored system property to "true" (the default value is "false").
