Apache CXF实战之二:集成Sping与Web容器

开发 后端
Apache的CXF现在几乎成了Java领域构建Web Service的首选类库,并且它也确实简单易用,下面就通过几篇系列文章做一下简单介绍。

书接上文,下面看看CXF怎样和spring集成。

1.创建HelloWorld 接口类

  1. package com.googlecode.garbagecan.cxfstudy.helloworld;  
  2.  
  3. import javax.jws.WebMethod;  
  4. import javax.jws.WebParam;  
  5. import javax.jws.WebResult;  
  6. import javax.jws.WebService;  
  7.  
  8. @WebService 
  9. public interface HelloWorld {  
  10.     @WebMethod 
  11.     @WebResult String sayHi(@WebParam String text);  

2.创建HelloWorld实现类

  1. package com.googlecode.garbagecan.cxfstudy.helloworld;  
  2.  
  3. public class HelloWorldImpl implements HelloWorld {  
  4.  
  5.     public String sayHi(String name) {  
  6.         String msg = "Hello " + name + "!";  
  7.         return msg;  
  8.     }  

3.修改web.xml文件

  1. <!DOCTYPE web-app PUBLIC  
  2.  "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
  3.  "http://java.sun.com/dtd/web-app_2_3.dtd" >  
  4.  
  5. <web-app>  
  6.  
  7.     <display-name>cxfstudy</display-name>  
  8.  
  9.     <servlet>  
  10.         <servlet-name>cxf</servlet-name>  
  11.         <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>  
  12.         <load-on-startup>1</load-on-startup>  
  13.     </servlet>  
  14.  
  15.     <servlet-mapping>  
  16.         <servlet-name>cxf</servlet-name>  
  17.         <url-pattern>/ws/*</url-pattern>  
  18.     </servlet-mapping>  
  19.  
  20.     <listener>  
  21.         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
  22.     </listener>  
  23.       
  24.     <context-param>  
  25.         <param-name>contextConfigLocation</param-name>  
  26.         <param-value>classpath*:**/spring.xml</param-value>  
  27.     </context-param>  
  28.       
  29. </web-app> 

4.创建spring配置文件并放在classpath路径下

  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <beans xmlns="http://www.springframework.org/schema/beans" 
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws" 
  4.     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd      
  5. http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">  
  6.     <import resource="classpath:META-INF/cxf/cxf.xml" />  
  7.     <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />  
  8.     <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />  
  9.     <jaxws:endpoint id="helloworld" implementor="com.googlecode.garbagecan.cxfstudy.helloworld.HelloWorldImpl" address="/HelloWorld" />  
  10.       
  11.     <!-- For client test -->  
  12.     <jaxws:client id="helloworldClient" address="http://localhost:9000/ws/HelloWorld" serviceClass="com.googlecode.garbagecan.cxfstudy.helloworld.HelloWorld" />     
  13. </beans>  

5.创建测试类

  1. package com.googlecode.garbagecan.cxfstudy.helloworld;  
  2.  
  3. import org.springframework.context.ApplicationContext;  
  4. import org.springframework.context.support.ClassPathXmlApplicationContext;  
  5.  
  6. public class SpringClient {  
  7.     public static void main(String[] args) {  
  8.         ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");  
  9.         HelloWorld helloworld = (HelloWorld)context.getBean("helloworldClient");  
  10.         System.out.println(helloworld.sayHi("kongxx"));  
  11.     }  
  12. }  

6.测试

6.1 首先启动tomcat或者使用maven的jetty,并访问http://localhost:9000/ws/HelloWorld?wsdl来验证web service已经启动并且生效;

6.2 然后运行测试类来验证web service。
