Apache CXF实战之一

泰山神 · 发表于 2017-1-1 08:17:39

Apache的CXF现在几乎成了Java领域构建Web Service的首选类库，并且它也确实简单易用，下面就通过几篇系列文章做一下简单介绍。
当然首先想到的当然还是那个Hello World示例。这个系列文章中用到的例子都是基于Maven构建的工程，下面是我的pom.xml文件内容

下面来看看HelloWorld的具体例子。
1.创建HelloWorld 接口类

package com.googlecode.garbagecan.cxfstudy.helloworld;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
@WebService
public interface HelloWorld {
@WebMethod
@WebResult String sayHi(@WebParam String text);
}

2.创建HelloWorld实现类

package com.googlecode.garbagecan.cxfstudy.helloworld;
public class HelloWorldImpl implements HelloWorld {
public String sayHi(String name) {
String msg = "Hello " + name + "!";
return msg;
}
}

3.创建Server端测试类

package com.googlecode.garbagecan.cxfstudy.helloworld;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
// http://localhost:9000/HelloWorld?wsdl
public class Server {
public static void main(String[] args) throws Exception {
JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
factory.setServiceClass(HelloWorldImpl.class);
factory.setAddress("http://localhost:9000/ws/HelloWorld");
factory.create();
System.out.println("Server start...");
Thread.sleep(60 * 1000);
System.out.println("Server exit...");
System.exit(0);
}
}

4.创建Client端测试类

package com.googlecode.garbagecan.cxfstudy.helloworld;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
public class Client {
public static void main(String[] args) {
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(HelloWorld.class);
factory.setAddress("http://localhost:9000/ws/HelloWorld");
HelloWorld helloworld = (HelloWorld) factory.create();
System.out.println(helloworld.sayHi("kongxx"));
System.exit(0);
}
}

5.测试
首先运行Server类来启动Web Service服务，然后访问http://localhost:9000/ws/HelloWorld?wsdl地址来确定web service启动正确。
运行Client测试类，会在命令行输出Hello kongxx!的message
