  • setResourceClasses() is for root resources only, use setProvider() or setProviders() for @Provider-annotated classes.
  • By default, the JAX-RS runtime is responsible for the lifecycle of resource classes, default lifecycle is per-request. You can set the lifecycle to singleton by using following line:

    Code Block
    java
    java
    sf.setResourceProvider(BookStore.class, new SingletonResourceProvider(new BookStore()));

Note that even though no Spring is explicitly used in the previous section, it is still used by default

Spring Boot

Please see CXF SpringBoot documentation. 

Please see JAX-RS Spring Boot and JAX-RS Spring Boot Scan demos.

Please see JAXRSClientSpringBoot documentation on how CXF JAX-RS Clients can be used in a SpringBoot Application. 

 

Configuring JAX-RS endpoints programmatically without Spring

Note that even though no Spring is explicitly used in the previous section, it is still used by default to have various CXF components registered with the bus such as transport factories. If no Spring libraries are available on the classpath then please follow the following example :

sf.setResourceClasses(CustomerService.class);
sf.setResourceProvider(CustomerService.class, new SingletonResourceProvider(new CustomerService()));
sf.setAddress("http://localhost:9000/");
BindingFactoryManager manager = sf.getBus().getExtension(BindingFactoryManager.class);

h1. Configuring JAX-RS services in container with Spring configuration file.

h2. web.xml

In web.xml one needs to register one or more CXFServlet(s) and link to an application context configuration.

h3. Using Spring ContextLoaderListener

Blueprint Web

This section describes how CXF JAX-RS endpoints can be bootstrapped with CXFBlueprintServlet and Blueprint contexts.

This approach is recommended for developers building CXF JAX-RS endpoints to be deployed in OSGI and which will do RequestDispatcher-based forwards.

Additionally it allows to reuse the same Blueprint contexts between OSGI and non-OSGI deployments.

Both options below work with CXF 3.1.3:

Code Block
xml
xml
<dependency>
  <groupId>org.apache.cxf</groupId>
  <artifactId>cxf-rt-frontend-jaxrs</artifactId>
  <version>3.1.3</version>
</dependency>

 

Maven dependencies

OSGI

xml
xml
<dependency>
  <groupId>org.apache.aries.blueprint</groupId>
  <artifactId>org.apache.aries.blueprint.webosgi</artifactId>
  <version>1.0.1</version>
</dependency>

In OSGI (Karaf) one should also install a 'war' feature.

Servlet Container

Common example

 

This web.xml shows how to setup CXFBlueprintServlet which processes this Blueprint context. It works exactly the same way in OSGI and non-OSGI environments.

    implements BookInterface {

    public Book getThatBook(@PathParam("bookId") Long id) 
        throws BookNotFoundFault {
        return doGetBook(id);
    }

    @Path("/thebook")
    public Book getTheBook(@PathParam("bookId") Long id) 
        throws BookNotFoundFault {
        return doGetBook(id);
    }
}
{code}

In

will

the

method

...

which

...

needs

...

to

as

...

getThatBook(...)

...

will

...

be

...

part

...

of

the

interface.

...

The

getTheBook()

...

can

not

...

be

to

Note that multiple service  or providers class names are separated by a comma. Users may want to use a "class.parameter.split.char" servlet parameter with the value "space" when

migrating from the older CXF versions were the space was used to separate multiple class names.

Note that having the web-app_2_3.dtd

consider

Lifecycle management

From Spring

By default, the service beans which are referenced directly from the jaxrs:server endpoint declarations are treated by the runtime as singleton JAX-RS root resources. For example:

h1. Lifecycle management

h2. From Spring

By default, the service beans which are referenced directly from the jaxrs:server endpoint declarations are treated by the runtime as singleton JAX-RS root resources. For example:

{code:xml}
<beans>
  <jaxrs:server id="customerService" address="/service1">
    <jaxrs:serviceBeans>
      <ref bean="customerBean" />
    </jaxrs:serviceBeans>
  </jaxrs:server>
  <!--
    The scope attribute, if any, will be ignored. For example, adding the scope attribute with the value
    "request", "prototype", etc, won't have any effect, the customerBean will still be treated as 
    a JAX-RS singleton by the runtime.
  --> 
  <bean id="customerBean" class="demo.jaxrs.server.CustomerService" />
</beans>
{code}

Spring

...

instantiates

...

and

...

injects

...

the

...

customerBean

...

reference

...

and

...

the

...

runtime

...

will

...

access

...

this

...

reference

...

directly

...

afterwards.

...

Effectively,

...

the

...

scope

...

attribute

...

which

...

may

...

be

...

present

...

on

...

the

...

customerBean

...

bean

...

declaration

...

is

...

ignored

...

in

...

this

...

case,

...

unless

...

the

...

Spring

...

AOP

...

is

...

used

...

to

...

enforce

...

the

...

required

...

scope

...

(see

...

below

...

for

...

more

...

information).

...

The

...

'serviceFactories'

attribute

...

has

to

be

used

a

'prototype',

...

'request'

...

and

...

other

...

Spring

...

bean

...

scopes

...

be

...

supported.

...

For

...

example,

...

the

...

serviceFactories

element

...

can

...

reference

...

one

...

or

...

more

...

beans

...

of

type

'org.apache.cxf.jaxrs.spring.SpringResourceFactory'

In

Other

If

seems

a

bit

verbose

Another

in

addition,

the

(example,

instances)

...

are

not

actually

at

thus

...

one

limitation

of

the

configuration

...

is

...

that

...

it

...

is

...

not

possible

...

to

...

inject

JAX-RS

contexts

...

into

these

...

This

is

not

a

show-stopper

because

contexts

such

as

UriInfo

...

can

...

be

...

passed

in

as

resource

However,

if

the

the

or

...

then

...

a

little

...

customization

...

of

...

the

...

org.apache.cxf.jaxrs.spring.SpringResourceFactory

...

will

...

do

...

the

...

trick.

...

Particularly,

...

the

...

Spring

...

ApplicationContext

...

reports

...

that

...

a

...

request-scoped

...

bean

...

is

...

a

...

singleton

...

but

...

the

...

JAX-RS

...

runtime

...

can

not

inject

thread-local

...

proxies

...

given

...

that

...

the

...

actual

...

instance

...

is

...

not

...

available

...

as

...

explained

...

above;

...

in

...

fact,

...

the

...

request-scoped

...

beans

...

are

...

not

...

really

...

JAX-RS

...

singletons.

...

Thus

...

a

simple

custom

factory

...

like

...

this

one

...

is

...

needed

and

it

h2. PostConstruct and PreDestroy

Bean methods annotated with @PostConstruct and @PreDestroy annotations will be called as expected by the scope rules. 
Singleton beans will have their postconstruct method called when the endpoint is created. If a given singleton resource instance was created by Spring then its predestroy method will also be called after, for example, the web application which uses it is about to be unloaded. At the moment singletons created by CXFNonSpringJaxrsServlet or programmatically will only have their postconstruct method (if any) called.  

Prototype beans will have their postconstruct and predestroy method called before a resource method is invoked and immediately after the invocation has returned but before the response has actually been serialized. You can indicate that the predestroy method has to be called after the request has completely gone out of scope (that is after the response body if any has been written to the output stream) by adding an

Sharing providers between multiple endpoints

One way to share multiple providers between multiple endpoints is to refer to the same provider bean from within jaxrs:provider sections:

<beans>
  
  <cxf:bus>
        <cxf:properties>
            <entry key="javax.ws.rs.ext.ExceptionMapper" value-ref="exceptionMapper"/>
        </cxf:properties>
  </cxf:bus

  <bean id="exceptionMapper" class="org.apache.cxf.systest.jaxrs.RuntimeExceptionMapper"/>

      <bean class="org.apache.cxf.systest.jaxrs.CustomerService2"/>
    </jaxrs:serviceBeans>
  </jaxrs:server>
  
  </beans>
{code}

Note a global exception mapper has been registered using the name of interface, "javax.ws.rs.ext.ExceptionMapper", which all the exception mappers have to implement. 

Note that once can register global per-bus providers using "javax.ws.rs.ext.ExceptionMapper", "javax.ws.rs.ext.MessageBodyReader" or "javax.ws.rs.ext.MessageBodyWriter" bus properties with the registered providers expected to implement either of these interfaces. 

Alternatively, one can have all the providers (JAX-RS and CXF-specific) registered with a bus using "org.apache.cxf.jaxrs.bus.providers" list property:

{code:xml}
<beans xmlns:util="http://www.springframework.org/schema/util">
  
  <cxf:bus>
        <cxf:properties>
            <entry key="org.apache.cxf.jaxrs.bus.providers" ref="busProviders"/>

h1. Dynamic servlets and a single JAX-RS endpoint

In some advanced cases you may want to dynamically add new servlets (CXFServlet or CXFNonSpringJaxrsServlet) with all of them serving the same JAX-RS endpoints. In this case you most likely want to configure servlets so that the CXF endpoint address is not overridden :

{code:xml}
{code:xml}
<servlet>
 <servlet-name>CXFServlet</servlet-name>
 <display-name>CXF Servlet</display-name>
 <servlet-class>
     org.apache.cxf.transport.servlet.CXFServlet
 </servlet-class>
 <init-param>
    <param-name>config-location</param-name>
    <param-value>/WEB-INF/beans1.xml</param-value>
 </init-param>
 <init-param>
    <param-name>disable-address-updates</param-name>
    <param-value>true</param-value>
 </init-param>
 <load-on-startup>1</load-on-startup>
</servlet>
{code}

{code}

h1. Servlet Container Configuration

In some cases servlet containers may have to be configured to get URI containing various encoded characters passed to the JAX-RS runtime unchanged.

h2. Tomcat

1. System "org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH"
and "org.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH" properties may have to be set to "true" to support URIs containing encoded forward or backward slashes.
2. When using mod_jk - ensure that the JkOptions setting has +ForwardURICompatUnparsed set. 
3. Windows: upgrade isapi_redirect.dll if you see URI containing encoded spaces being decoded by Tomcat.
.jaxrs.CustomerService2"/>
    </jaxrs:serviceBeans>
  </jaxrs:server>
  
  </beans>

Note a global exception mapper has been registered using the name of interface, "javax.ws.rs.ext.ExceptionMapper", which all the exception mappers have to implement.

Note that once can register global per-bus providers using "javax.ws.rs.ext.ExceptionMapper", "javax.ws.rs.ext.MessageBodyReader" or "javax.ws.rs.ext.MessageBodyWriter" bus properties with the registered providers expected to implement either of these interfaces.

Alternatively, one can have all the providers (JAX-RS and CXF-specific) registered with a bus using "org.apache.cxf.jaxrs.bus.providers" list property:

    <ref bean="exceptionMapper"/>
    <ref bean="customMessageBodyReader"/>
    <ref bean="customMessageBodyWriter"/>
  </util:list>

  <bean id="customMessageBodyReader" class="org.apache.cxf.systest.jaxrs.CustomReader"/>
  <bean id="customMessageBodyWriter" class="org.apache.cxf.systest.jaxrs.CustomWriter"/> 

  <jaxrs:server id="customerService" address="/service1">
    <jaxrs:serviceBeans>
      <bean class="org.apache.cxf.systest.jaxrs.CustomerService"/>
    </jaxrs:serviceBeans>
  </jaxrs:server>

  <jaxrs:server id="customerService" address="/service2">

      <bean class="org.apache.cxf.systest.jaxrs.CustomerService2"/>
    </jaxrs:serviceBeans>
  </jaxrs:server>
  
  </beans>

Dynamic servlets and a single JAX-RS endpoint

Note: this is not required by default starting from CXF 3.0.0-milestone1

In some advanced cases you may want to dynamically add new servlets (CXFServlet or CXFNonSpringJaxrsServlet) with all of them serving the same JAX-RS endpoints. In this case you most likely want to configure servlets so that the CXF endpoint address is not overridden :

Code Block

xml
{code:xml}
<servlet>
 <servlet-name>CXFServlet</servlet-name>
 <display-name>CXF Servlet</display-name>
 <servlet-class>
     org.apache.cxf.transport.servlet.CXFServlet
 </servlet-class>
 <init-param>
    <param-name>config-location</param-name>
    <param-value>/WEB-INF/beans1.xml</param-value>
 </init-param>
 <init-param>
    <param-name>disable-address-updates</param-name>
    <param-value>true</param-value>
 </init-param>
 <load-on-startup>1</load-on-startup>
</servlet>


Auto-discovery of root resources and providers

Starting from CXF 3.0.0 it is possible to enable the auto-discovery of JAX-RS roots and providers with the regular CXF JAX-RS endpoint declarations done in XML . Currently it is only possible with Spring. Patch supporting it for Blueprint is available and will be dealt with asap.

 

Spring

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:jaxrs="http://cxf.apache.org/jaxrs"
      xsi:schemaLocation="
         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
         http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd">

     <import resource="classpath:META-INF/cxf/cxf.xml" />
     
     <!-- 
         Discover all root resources and providers in packages starting from "a.b.c" 
     -->
     <jaxrs:server address="/customers" basePackages="a.b.c"/>

     <!-- 
       Discover a root resource and providers in packages starting from "a.b.c" and "d.e.f",
       Note that in case of jaxrs:client, having multiple discoverable root resources can lead to
       unexpected results, as only the single root can be recognized 
     -->
     <jaxrs:client address="http://customers" basePackages="a.b.c,d.e.f"/>

 </beans>

Note the above does not require Spring annotations such as @Component added to JAX-RS provider or resources.

If you prefer doing a pure Spring-based auto-discovery you can have @Component added to JAX-RS application classes and do

Servlet and Application Container Configuration

Please see this page for more information.

Starting from CXF 3.1.0: org.apache.cxf.jaxrs.servlet.sci.JaxrsServletContainerInitializer implementing javax.servlet.ServletContainerInitializer is shipped in a cxf-rt-rs-http-sci module.

Adding this module will support  no-web.xml and other JAX-RS deployments depending on the container auto-discovery mechanism as described in a 2.3.2 section of JSR-339 (JAX-RS 2.0).
