《转》利用cxf实现webservice
首先下载cxf包,目前最新的版本是apache-cxf-2.1.,下栽地址http://cxf.apache.org/download.html。
1. 首先新建一个web工程CxfService,倒入cxf所学要的包。要倒入的包如下:
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-2.1.jar jaxb-impl-2.1.6.jar jaxws-api-2.1.jar jetty-6.1.5.jar jetty-util-6.1.5.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 (optional - for XML Configuration support):
aopalliance-1.0.jar spring-core-2.0.4.jar spring-beans-2.0.4.jar spring-context-2.0.4.jar spring-web-2.0.4.jar
And the CXF jar:
cxf-2.1.jar2.新建一个接口类:HelloWorld,如下:
- package com.zx.cxf.service;
- import javax.jws.WebParam;
- import javax.jws.WebService;
- @WebService
- public interface HelloWorld {
- String sayHi(@WebParam(name="text") String text);
- }
创建接口的实现类:HelloWorldImpl,如下
- package com.zx.cxf.service;
- import javax.jws.WebService;
- import com.zx.cxf.service.HelloWorld;
- @WebService(endpointInterface = "com.zx.cxf.service.HelloWorld",
- serviceName = "HelloWorld")
- public class HelloWorldImpl implements HelloWorld {
- public String sayHi(String text) {
- return "Hello " + text;
- }
- }
*@WebService:申明为webservice的注解
*endpointInterface:要暴露的接口类
*serviceName : 服务名
在WEB-INF目录下新建beans.xml,如下:
- <?xml version="1.0" encoding="UTF-8"?>
- <!-- START SNIPPET: beans -->
- <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.zx.cxf.service.HelloWorldImpl"
- address="/HelloWorld" />
- </beans>
- <!-- END SNIPPET: beans -->
address: 要和注释里面神秘的服务名对应,
修改web.xml文件,如下:
- <?xml version="1.0" encoding="ISO-8859-1"?>
- <!DOCTYPE web-app
- PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
- "http://java.sun.com/dtd/web-app_2_3.dtd">
- <!-- START SNIPPET: webxml -->
- <web-app>
- <context-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>/WEB-INF/beans.xml</param-value>
- </context-param>
- <listener>
- <listener-class>
- org.springframework.web.context.ContextLoaderListener
- </listener-class>
- </listener>
- <servlet>
- <servlet-name>CXFServlet</servlet-name>
- <display-name>CXF Servlet</display-name>
- <servlet-class>
- org.apache.cxf.transport.servlet.CXFServlet
- </servlet-class>
- <load-on-startup>1</load-on-startup>
- </servlet>
- <servlet-mapping>
- <servlet-name>CXFServlet</servlet-name>
- <url-pattern>/services/*</url-pattern>
- </servlet-mapping>
- </web-app>
- <!-- END SNIPPET: webxml -->
启动tomcat
测试:简单的测试就是ie测试,在浏览器中输入http://localhost:8080/CxfService/services/,如果出现
{http://service.cxf.zx.com/}HelloWorldImplPort ,或者输入http://localhost:8080/CxfService/services/HelloWorld?wsdl,出现wsdl文挡,则说明服务器端配置成功。
可户端测试:
测试类如下:
- package com.zx.cxf.service;
- import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
- import org.apache.cxf.interceptor.*;
- import com.zx.cxf.service.HelloWorld;
- public class client {
- private client() {
- }
- public static void main(String args[]) throws Exception {
- JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
- factory.getInInterceptors().add(new LoggingInInterceptor());
- factory.getOutInterceptors().add(new LoggingOutInterceptor());
- factory.setServiceClass(HelloWorld.class);
- factory.setAddress("http://localhost:8080/CxfService/services/HelloWorld");
- HelloWorld client = (HelloWorld) factory.create();
- String reply = client.sayHi("HI");
- System.out.println("Server said: " + reply);
- }
- }
如果控制台打印出:Server said: Hello HI则说明测试成功。
Ps:如果出现in thread "main" javax.xml.ws.soap.SOAPFaultException: Error reading XMLStreamReader.
关掉防火墙就可以了。
下面是源文件:下载后倒入所需要的包
- CxfService.rar (5.5 KB)
@WebService和@WebMethod | 是WSDL映射Annotation.这些Annotation将描述Web Service的WSDL文档元素和JAVA源代码联系在一起。 |
@WebService和@WebMethod | WSDL映射Annotation.这些Annotation将描述Web Service的WSDL文档元素和JAVA源代码联系在一起。 |
@WebService | annotation的元素name,serviceName和targetNamespace成员用来描述wsdl:protType,wsdl:service,和targetNameSpace生成WebService中的WSDL文件。 |
@SOAPBinding | 是一个用来描述SOAP格式和RPC的协议的绑定Annotation. |
@WebMethod | Annotation的operationName成员描述了wsdl:operation,而且它的操作描述了WSDL文件中的SOAPAction头部,这是客户端必须要放入到SOAPHeader中的数值,SOAP1.1中的一种约束。 |
@WebParam | 是一个用来描述SOAP格式和RPC的协议的绑定Annotation. |
@WebResult | Annotation的partName成员描述了wsdl:part用来返回WSDL文档的值。 |
