基于CXF的webService本地数据交互----PC端与Android端（一）

1.下载CXF（我下载的是2.4.6）

http://cxf.apache.org/download.html

2.新建一个web项目，项目结构如附件所示。
基于CXF的webService本地数据交互----PC端与Android端（一）

为了方便，我们将下载的CXF包lib文件夹下的jar包全部导入到工程中。

(实际用到的jar包可看附件图)
基于CXF的webService本地数据交互----PC端与Android端（一）

3.服务端

a.建一个服务接口 IHelloWorld.java

package com.royal.service;

import java.util.List;

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface IHelloWorld {

	public String sayHi(@WebParam(name = "text") String text);

	public int getNumber();

	public String getNameAndAge(@WebParam(name = "nameid") String nameid, @WebParam(name = "number") int number);

	public List getList();

}

其实我测试过了，不用@WebParam("")声明也行。

b.服务接口的实现类 HelloWorldImpl.java

package com.royal.serviceImpl;

import java.util.ArrayList;
import java.util.List;

import javax.jws.WebService;

import com.royal.service.IHelloWorld;

/**
 * 接口实现
 * 
 * @author Royal 注意：@webservice自动注入一定要写
 * 
 */
@WebService(endpointInterface = "com.royal.service.IHelloWorld", serviceName = "HelloWorldService")
public class HelloWorldImpl implements IHelloWorld {

	public String sayHi(String text) {
		return text + "Hi";
	}

	public int getNumber() {
		return 100;
	}

	public String getName(String nameid) {
		return nameid;
	}

	public List getList() {
		List list = new ArrayList<String>();
                list.add("萧瑟");
                list.add(10);	
		return null;
	}

}

c.服务接口集合spring的配置 beanRefServer.xml

<?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 Apache CXF Bean Definition -->
	<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" />

	<!-- implementor ：接口类的实现类 address： 要和注释里面神秘的服务名对应， -->
	<jaxws:endpoint id="helloWorld"
		implementor="com.royal.serviceImpl.HelloWorldImpl" address="/HelloWorldService" />

</beans>

d.web.xml的配置 web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	
	<!-- Spring Config Location -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/classes/beanRefServer.xml</param-value>
    </context-param>
    <!-- Spring ContextLoaderListener -->
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    
     <!-- Apache CXFServlet -->
    <servlet>
        <servlet-name>CXFServlet</servlet-name>
        <servlet-class>
            org.apache.cxf.transport.servlet.CXFServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- CXFServlet Mapping -->
    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>
	
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

OK,这样服务端的配置就完成了，启动tomcat。

4.在浏览器中输入：http://localhost:服务器端口/项目名/services

如果看见：WSDL : {http://serviceImpl.royal.com/}HelloWorldService ，则代表成功。

点击WSDL链接，可看见WSDL文件内容。

=========================================================

小结：

其配置流程步骤可认为

------sevlet: 拦截注意name及mapping

<servlet>
        <servlet-name>CXFServlet</servlet-name>
        <servlet-class>
            org.apache.cxf.transport.servlet.CXFServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- CXFServlet Mapping -->
    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>

------新增自定义xml文件：

作用：声明地址访问信息，根据指定的地址找到实现类

<!-- implementor ：接口类的实现类 address： 要和注释里面神秘的服务名对应， -->
	<jaxws:endpoint id="xxxxxxx"
		implementor="xxxxxxxxx.xxxImpl" address="/xxxxxx" />

（之后将该文件配置进web.xml，这样服务启动的时候就被加入了）

-------实现类：

作用：匹配自定义xml文件中的地址名

可切入一个接口，暴露提供给用户

@WebService(endpointInterface = "xxxxx", serviceName = "xxxxxx")
public class xxxxxImpl implements xxxxxx {
}

这部分当做个人小结，可无视。

==================================================================

5.客户端

写一个客户端测试类 CXFClient.java

package com.royal.client;

import java.util.List;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import com.royal.service.IHelloWorld;

public class CXFClient {
	
	public CXFClient(){
		
	}
	
	public static void main(String args[]) throws Exception {
		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
		factory.getInInterceptors().add(new LoggingInInterceptor());
		factory.getOutInterceptors().add(new LoggingOutInterceptor());
		factory.setServiceClass(IHelloWorld.class);  
		factory.setAddress("http://localhost:8090/cxf_webservice/services/HelloWorldService");
		IHelloWorld client = (IHelloWorld) factory.create();

		String hi = client.sayHi("萧_瑟");  
		int number = client.getNumber();
		String NameAge = client.getNameAndAge("萧_瑟",18);
		List list = client.getList();
		
		System.out.println("hi----" + hi);
		System.out.println("number----" + number);
		System.out.println("NameAge----" + NameAge);
		System.out.print("list----");
		for(int i = 0; i < list.size(); i++){
			System.out.print(list.get(i) + ",");
		}
	}

}

6. 打印结果：

hi----萧_瑟 Hi
number----100
NameAge----萧_瑟18
list----10,萧_瑟,
