几种调用web service的方式【含spring】

首先写一个服务端：

package com.pp.ws.server;
    
    import javax.jws.WebMethod;
    import javax.jws.WebParam;
    import javax.jws.WebService;
    
    @WebService(targetNamespace="http://wsapi.pp1618.com", serviceName="PPLoginService")
    public class LoginService {
    	
    	@WebMethod
    	public String login(@WebParam(name="username") String username, @WebParam(name="password") String password){
    		if(username != null && username.equals(password)){
    			return "OK";
    		}
    		return "Faliure";
    	}
    }

package com.pp.ws.server;
    
    import javax.xml.ws.Endpoint;
    
    public class AppServer  {
        public static void main( String[] args ) {
        	Endpoint.publish("http://127.0.0.1:6644/user/login", new LoginService());
        }
    }

启动。

然后，用wsimport（JDK自带命令，本文章中使用的是JDK1.8）生成源代码，命令如下：

wsimport -s ./src -p com.pp.client.ws -encoding utf-8 http://127.0.0.1:6644/user/login?wsdl

另外新建一个maven项目，把上面生成的代码（src目录）拷贝到项目的src目录中去

代码结构如下：

![Center][]

并且加入spring依赖

<dependency>
    	<groupId>org.springframework</groupId>
    	<artifactId>spring-web</artifactId>
    	<version>4.3.2.RELEASE</version>
    </dependency>

调用的示例代码如下：

package com.pp.client;
    
    import java.net.MalformedURLException;
    import java.net.URL;
    
    import javax.xml.namespace.QName;
    import javax.xml.ws.Service;
    
    import org.springframework.context.annotation.AnnotationConfigApplicationContext;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean;
    
    import com.pp.client.ws.LoginService;
    import com.pp.client.ws.PPLoginService;
    
    public class AppClient {
    
    	//方式一
    	public static void fun1() throws Exception {
    		URL url = new URL("http://127.0.0.1:6644/user/login?wsdl");
    		//QName的两个参数，参照LoginService上面的注解
    		QName qname = new QName("http://wsapi.pp1618.com", "PPLoginService");
    		Service service = Service.create(url, qname);  
    		LoginService ls = service.getPort(LoginService.class);
    		System.out.println(ls.login("admin", "123"));
    		System.out.println(ls.login("admin", "admin"));
    	}
    	
    	//方式二(PPLoginService内部其实使用的是方式一)
    	public static void fun2() throws Exception {
    		URL url = new URL("http://127.0.0.1:6644/user/login?wsdl");
    		PPLoginService ppls = new PPLoginService(url);
    		LoginService ls = ppls.getLoginServicePort();
    		System.out.println(ls.login("admin", "123"));
    		System.out.println(ls.login("admin", "admin"));
    	}
    	
    	//方式三，使用spring封装的方式
    	public static void fun3() throws Exception {
    		AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(WSConfig.class);
    		LoginService ls = context.getBean(LoginService.class);
    		System.out.println(ls.login("admin", "123"));
    		System.out.println(ls.login("admin", "admin"));
    		context.close();
    	}
    	
    	public static void main(String[] args) throws Exception {
    		fun1();
    		fun2();
    		fun3();
    	}
    }
    
    @Configuration
    class WSConfig {
    	
    	@Bean
    	public JaxWsPortProxyFactoryBean createMainCouponService() throws MalformedURLException {
    		//JaxWsPortProxyFactoryBean 类在spring-web.jar里面
    		JaxWsPortProxyFactoryBean bean = new JaxWsPortProxyFactoryBean();
    		bean.setServiceInterface(LoginService.class);
    		bean.setServiceName("PPLoginService");
    		bean.setWsdlDocumentUrl(new URL("http://127.0.0.1:6644/user/login?wsdl"));
    		//设置超时
    		bean.addCustomProperty("com.sun.xml.internal.ws.request.timeout", 20000);
    		bean.addCustomProperty("com.sun.xml.internal.ws.connect.timeout", 20000);
    		return bean;
    	}
    }

需要注意的是：前两种方式是使用JDK自带的方式，第三种是spring封装的调用方式
