Spring+CXF的WebServices简单示例

本文就最简单的WebServices示例来演示Spring和CXF的整合。

1. 使用Maven创建webapp项目，pom如下

   <properties>
   	<cxf.version>2.2.3</cxf.version>
   </properties>
   
   <dependencies>
   	<dependency>
   		<groupId>javax.servlet</groupId>
   		<artifactId>javax.servlet-api</artifactId>
   		<version>3.1.0</version>
   	</dependency>
   
   	<dependency>
   		<groupId>org.springframework</groupId>
   		<artifactId>spring-webmvc</artifactId>
   		<version>4.1.4.RELEASE</version>
   	</dependency>
   
   	<dependency>
   		<groupId>org.apache.cxf</groupId>
   		<artifactId>cxf-rt-frontend-jaxws</artifactId>
   		<version>${cxf.version}</version>
   	</dependency>
   	<dependency>
   		<groupId>org.apache.cxf</groupId>
   		<artifactId>cxf-rt-transports-http</artifactId>
   		<version>${cxf.version}</version>
   	</dependency>
   	<!-- Jetty is needed if you're are not using the CXFServlet -->
   	<dependency>
   		<groupId>org.apache.cxf</groupId>
   		<artifactId>cxf-rt-transports-http-jetty</artifactId>
   		<version>${cxf.version}</version>
   	</dependency>
   
   	<dependency>
   		<groupId>junit</groupId>
   		<artifactId>junit</artifactId>
   		<version>4.12</version>
   		<scope>test</scope>
   	</dependency>
   </dependencies>

2. 需要暴露的服务

   @WebService
   public class Hello {
   	public String say(){
   		return "hello,kevin";
   	}
   }

3. Spring配置文件

   <?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">
   
   	<bean id="hello" class="net.oseye.Hello"></bean>
   	
   	<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="helloService" implementor="#hello" address="/hello" />
   </beans>

4. web.xml

   <!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>Archetype Created Web Application</display-name>
   
   	<!-- needed for ContextLoaderListener -->
   	<context-param>
   		<param-name>contextConfigLocation</param-name>
   		<param-value>classpath:applicationContext.xml</param-value>
   	</context-param>
   
   	<!-- Bootstraps the root web application context before servlet initialization -->
   	<listener>
   		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   	</listener> 
   	
   	<servlet>
   		<servlet-name>cxf</servlet-name>
   		<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
   	</servlet> 
   	<servlet-mapping>
   		<servlet-name>cxf</servlet-name>
   		<url-pattern>/*</url-pattern>
   	</servlet-mapping>
   </web-app>

5. 运行
