Apache CXF 和 Spring 结合使用

• Setting up your build

Open up your favorite IDE and create a new project. The first thing we need to do is add the necessary CXF dependencies to the project. You can find these dependencies in the CXF distribution in the lib directory.

commons-logging-1.1.jar
geronimo-activation_1.1_spec-1.0-M1.jar (or Sun's Activation jar)
geronimo-annotation_1.0_spec-1.1.jar (JSR 250)
geronimo-javamail_1.4_spec-1.0-M1.jar (or Sun's JavaMail jar)
geronimo-servlet_2.5_spec-1.1-M1.jar (or Sun's Servlet jar)
geronimo-ws-metadata_2.0_spec-1.1.1.jar (JSR 181)
jaxb-api-2.0.jar
jaxb-impl-2.0.5.jar
jaxws-api-2.0.jar
neethi-2.0.jar
saaj-api-1.3.jar
saaj-impl-1.3.jar
stax-api-1.0.1.jar
wsdl4j-1.6.1.jar
wstx-asl-3.2.1.jar
XmlSchema-1.2.jar
xml-resolver-1.2.jar

The Spring jars:

aopalliance-1.0.jar
spring-core-2.0.8.jar
spring-beans-2.0.8.jar
spring-context-2.0.8.jar
spring-web-2.0.8.jar

And the CXF jar:

cxf-2.1.jar

• Writing your Service

First we'll write our service interface. It will have one operation called "sayHello" which says "Hello" to whoever submits their name.

package demo.spring;

import javax.jws.WebService;

@WebService
public interface HelloWorld {
    String sayHi(String text);
}

Our implementation will then look like this:

package demo.spring;

import javax.jws.WebService;

@WebService(endpointInterface = "demo.spring.HelloWorld")
public class HelloWorldImpl implements HelloWorld {

    public String sayHi(String text) {
        System.out.println("sayHi called");
        return "Hello " + text;
    }
}

The @WebService annotation on the implementation class lets CXF know which interface to use when creating WSDL. In this case its simply our HelloWorld interface.

• Declaring your server beans

CXF contains support for "nice XML" within Spring 2.0. For the JAX-WS side of things, we have a <jaxws:endpoint> bean which sets up a server side endpoint.

Lets create a "beans.xml" file in our WEB-INF directory which declares an endpoint bean:

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

	<import resource="classpath:META-INF/cxf/cxf.xml" />
	<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
	<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

	<jaxws:endpoint 
	  id="helloWorld" 
	  implementor="demo.spring.HelloWorldImpl" 
	  address="/HelloWorld" />
	  
</beans>

If you want to reference a spring managed-bean, you can write like this:

<bean id="hello" class="demo.spring.HelloWorldImpl" />

<jaxws:endpoint id="helloWorld" implementor="#hello" address="/HelloWorld" />
