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：

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
