使用cxf写web service的简单实例

增加CXF依赖

<dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>apache-cxf</artifactId>
        <version>${cxf.version}</version>
        <type>pom</type>
  </dependency>

创建服务接口

import javax.jws.WebService;

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

import javax.jws.WebService;

@WebService
public class HellowWordController implements HelloWorld {
    /*
     * (non-Javadoc)
     * 
     * @see com.wfj.infc.HelloWorld#sayHi(java.lang.String)
     */
    public String sayHi(String text) {
        // TODO Auto-generated method stub
        System.out.println("sayHi called");
        return "Hello " + text;
    }

}

cxfdemo-beans.xml

<?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"
       default-autowire="byName">

    <import resource="classpath:META-INF/cxf/cxf.xml"/>
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
    <bean id="hello" class="com.wangfj.product.core.controller.HellowWordController"/>
    <jaxws:endpoint id="helloWorld" implementor="#hello" address="/webservice/hw"/>
</beans>

在webapp中发布

XF提供了spring的集成，同时还提供了org.apache.cxf.transport.servlet.CXFServlet用于在 web容器中发布WebService。 前面的例子中增加了整个apache-cxf的依赖，所以会自动增加对srping的引用。只需要写beans配置文件和web.xml文件即可。

• 在web.xml中配置CXFServlet

 <servlet>
        <servlet-name>CXFServlet</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>

 <context-param>
         <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/cxfdemo-beans.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
