Apache CXF practice 2: Integration of Sping and Web containers

Next, let's take a look at how CXF is integrated with spring.

1. Create a HelloWorld Interface Class

 
 

  
  
package com.googlecode.garbagecan.cxfstudy.helloworld;  
  
  
 
  
  
import javax.jws.WebMethod;  
  
  
import javax.jws.WebParam;  
  
  
import javax.jws.WebResult;  
  
  
import javax.jws.WebService;  
  
  
 
  
  
@WebService 
  
  
public interface HelloWorld {  
  
  
    @WebMethod 
  
  
    @WebResult String sayHi(@WebParam String text);  
  
  
} 
 
 

2. Create a HelloWorld implementation class

 
 

  
  
package com.googlecode.garbagecan.cxfstudy.helloworld;  
  
  
 
  
  
public class HelloWorldImpl implements HelloWorld {  
  
  
 
  
  
    public String sayHi(String name) {  
  
  
        String msg = "Hello " + name + "!";  
  
  
        return msg;  
  
  
    }  
  
  
} 
 
 

3. Modify the web. xml file

 
 

  
  
<!DOCTYPE web-app PUBLIC  
  
  
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
  
  
 "http://java.sun.com/dtd/web-app_2_3.dtd" >  
  
  
 
  
  
<web-app>  
  
  
 
  
  
    <display-name>cxfstudy</display-name>  
  
  
 
  
  
    <servlet>  
  
  
        <servlet-name>cxf</servlet-name>  
  
  
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>  
  
  
        <load-on-startup>1</load-on-startup>  
  
  
    </servlet>  
  
  
 
  
  
    <servlet-mapping>  
  
  
        <servlet-name>cxf</servlet-name>  
  
  
        <url-pattern>/ws/*</url-pattern>  
  
  
    </servlet-mapping>  
  
  
 
  
  
    <listener>  
  
  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
  
  
    </listener>  
  
  
      
  
  
    <context-param>  
  
  
        <param-name>contextConfigLocation</param-name>  
  
  
        <param-value>classpath*:**/spring.xml</param-value>  
  
  
    </context-param>  
  
  
      
  
  
</web-app> 
 
 

4. Create a spring configuration file and place it in the classpath path.

 
 

  
  
<?xml version="1.0" encoding="UTF-8"?>  
  
  
<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="com.googlecode.garbagecan.cxfstudy.helloworld.HelloWorldImpl" address="/HelloWorld" />  
  
  
      
  
  
    <!-- For client test -->  
  
  
    <jaxws:client id="helloworldClient" address="http://localhost:9000/ws/HelloWorld" serviceClass="com.googlecode.garbagecan.cxfstudy.helloworld.HelloWorld" />     
  
  
</beans>  
 
 

5. Create a test class

 
 

  
  
package com.googlecode.garbagecan.cxfstudy.helloworld;  
  
  
 
  
  
import org.springframework.context.ApplicationContext;  
  
  
import org.springframework.context.support.ClassPathXmlApplicationContext;  
  
  
 
  
  
public class SpringClient {  
  
  
    public static void main(String[] args) {  
  
  
        ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");  
  
  
        HelloWorld helloworld = (HelloWorld)context.getBean("helloworldClient");  
  
  
        System.out.println(helloworld.sayHi("kongxx"));  
  
  
    }  
  
  
}  
 
 

6. Test

6.1 start tomcat or use jetty of maven and access http: // localhost: 9000/ws/HelloWorld? To verify that the web service has been started and takes effect;

6.2 then run the test class to verify the web service.
