cxf简单例子

cxf 这里介绍在web跟非web中的发布以及调用

准备条件：

1，导入cxf的相关jar包，以maven项目为例 pom的配置文件为

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<configuration>

</configuration>
</plugin>
</plugins>
</build>
</project>

2，创建实体类，接口以及实现类

package pBean;

public class Reader {

    private static final long serialVersionUID = 1L;

    private String name;

    private String password;

    public Reader(){}

    public Reader(String name,String password) {

        this.name = name;

        this.password = password;

    }

    public String getName() {

       return name;

    }

    public void setName(String name) {

       this.name = name;

    }

    public String getPassword() {

       return password;

    }

    public void setPassword(String password) {

        this.password = password;

    }

    //Get/Set方法省略

    public String toString(){

        return "Name:"+name+",Password:"+password;

    }

}

定义接口类

package pInterface;

import java.util.List;

import javax.jws.WebParam;

import javax.jws.WebService;

import pBean.Reader;

@WebService

public interface IReaderService {

    public Reader getReader(@WebParam(name = "name") String name,@WebParam(name = "password") String password);

    public List<Reader> getReaders();

}

Tip：（里的WebParam必须指定，否则调用的时候返回null）

定义实现类

package pImpl;

import java.util.ArrayList;

import java.util.List;

import javax.jws.WebParam;

import pBean.Reader;

import pInterface.IReaderService;

public class ReaderService implements IReaderService{

    public Reader getReader(@WebParam(name="name") String name,@WebParam(name="password") String password) {

            return new Reader(name,password);

        }

        public List<Reader> getReaders(){

            List<Reader> readerList = new ArrayList<Reader>();

            readerList.add(new Reader("shun1","123"));

            readerList.add(new Reader("shun2","123"));

            return readerList;

        }

}

目录结构

一、在非web中发布服务并调用

1，发布服务，

执行下面的main方法，这个服务就起来了，此时在浏览器输入http://localhost:8080/readerService?wsdl就能访问服务

package pTest;

import javax.xml.ws.Endpoint;

import pImpl.ReaderService;

/**

*@author chenrd

*@date 2018-3-20 下午3:55:42

*CXF自带了一个轻量的容器服务，相当于spring自己提供了IOC容器一样。

*我们可以先用它来测试一下我们部署成功没。

*/

public class Test {

    public static void main(String[] args) {

        System.out.println("Server is starting...");

        ReaderService readerService = new ReaderService();

        Endpoint.publish("http://localhost:8080/readerService",readerService);

        System.out.println("Server is started...");

    }

}

2，调用服务

package pTest;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import pBean.Reader;

import pInterface.IReaderService;

/**

*@author chenrd

*@date 2018-3-20 下午4:35:14

*业务：

*部署成功后，我们就是要调用啦，

*它的调用也相当简单，跟xfire类似，取得接口，然后就可以跟本地类一样调用方法了。

*/

public class Test2 {

    /**

    * 这里很简单，也是取得一个工厂类，

    * 然后直接设接口和地址再create就可以得取相应的接口了，

    * 这里跟xfire一样，也是需要调用端先定义好接口原型，否则这些调用将无从说起。

    */

    public static void main(String[] args) {

        JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();

        factoryBean.setServiceClass(IReaderService.class);

        factoryBean.setAddress("http://localhost:8080/readerService");

        IReaderService readerService = (IReaderService)factoryBean.create();

        Reader reader = readerService.getReader("shun","123");

        System.out.println("Reader:"+reader);

    }

}

二、在web中发布服务并调用

添加下面1和2的条件

1，在web.xml中添加


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

2，spring配置文件中的配置（这里单独放到了一个文件）

<?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">

<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="readerServicce2" implementor="pImpl.ReaderService" address="/readerService2" />
</beans>

说明：



发布（部署你的项目到tomcat并跑起来）

调用：

package pTest;

import javax.xml.namespace.QName;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

import pBean.Reader;

/**
* @author chenrd
* @date 2018-3-21 上午11:39:31 业务：
*/
public class Test3 {
public static void main(String[] args) {
//这个是用cxf 客户端访问cxf部署的webservice服务
//千万记住，访问cxf的webservice必须加上namespace ,否则通不过
//现在又另外一个问题，传递过去的参数服务端接收不到
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
//url为调用webService的wsdl地址
Client client = dcf.createClient("http://localhost:8080/CXF/webservice/readerService2?wsdl");
//第一个参数是wsdl的命名空间
QName qname=new QName("http://pInterface/","getReader");
//namespace是命名空间，methodName是方法名
String name = "name";
String pwd = "pwd";
//paramvalue为参数值
Object[] objects = null;
Object object = null;
try {
object = client.invoke(qname,name,pwd);
} catch (Exception e) {
e.printStackTrace();
}
//调用web Service//输出调用结果
System.out.println(object);
// System.out.println(((Reader)objects[0]).toString());
}
}
