几种调用web service的方式（含spring)

首先写一个服务端：

1.  
2. package com.pp.ws.server;
3.  
4. import javax.jws.WebMethod;
5. import javax.jws.WebParam;
6. import javax.jws.WebService;
7.  
8. @WebService(targetNamespace="http://wsapi.pp1618.com", serviceName="PPLoginService")
9. public class LoginService {
10.  
11. @WebMethod
12. public String login(@WebParam(name="username") String username, @WebParam(name="password") String password){
13. if(username != null && username.equals(password)){
14. return "OK";
15. }
16. return "Faliure";
17. }
18. }
19. package com.pp.ws.server;
20.  
21. import javax.xml.ws.Endpoint;
22.  
23. public class AppServer {
24. public static void main( String[] args ) {
25. Endpoint.publish("http://127.0.0.1:6644/user/login", new LoginService());
26. }
27. }

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

1.  
2. <dependency>
3. <groupId>org.springframework</groupId>
4. <artifactId>spring-web</artifactId>
5. <version>4.3.2.RELEASE</version>
6. </dependency>
7. 调用的示例代码如下：
8. package com.pp.client;
9.  
10. import java.net.MalformedURLException;
11. import java.net.URL;
12.  
13. import javax.xml.namespace.QName;
14. import javax.xml.ws.Service;
15.  
16. import org.springframework.context.annotation.AnnotationConfigApplicationContext;
17. import org.springframework.context.annotation.Bean;
18. import org.springframework.context.annotation.Configuration;
19. import org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean;
20.  
21. import com.pp.client.ws.LoginService;
22. import com.pp.client.ws.PPLoginService;
23.  
24. public class AppClient {
25.  
26. //方式一
27. public static void fun1() throws Exception {
28. URL url = new URL("http://127.0.0.1:6644/user/login?wsdl");
29. //QName的两个参数，参照LoginService上面的注解
30. QName qname = new QName("http://wsapi.pp1618.com", "PPLoginService");
31. Service service = Service.create(url, qname);
32. LoginService ls = service.getPort(LoginService.class);
33. System.out.println(ls.login("admin", "123"));
34. System.out.println(ls.login("admin", "admin"));
35. }
36.  
37. //方式二(PPLoginService内部其实使用的是方式一)
38. public static void fun2() throws Exception {
39. URL url = new URL("http://127.0.0.1:6644/user/login?wsdl");
40. PPLoginService ppls = new PPLoginService(url);
41. LoginService ls = ppls.getLoginServicePort();
42. System.out.println(ls.login("admin", "123"));
43. System.out.println(ls.login("admin", "admin"));
44. }
45.  
46. //方式三，使用spring封装的方式
47. public static void fun3() throws Exception {
48. AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(WSConfig.class);
49. LoginService ls = context.getBean(LoginService.class);
50. System.out.println(ls.login("admin", "123"));
51. System.out.println(ls.login("admin", "admin"));
52. context.close();
53. }
54.  
55. public static void main(String[] args) throws Exception {
56. fun1();
57. fun2();
58. fun3();
59. }
60. }
61.  
62. @Configuration
63. class WSConfig {
64.  
65. @Bean
66. public JaxWsPortProxyFactoryBean createMainCouponService() throws MalformedURLException {
67. //JaxWsPortProxyFactoryBean 类在spring-web.jar里面
68. JaxWsPortProxyFactoryBean bean = new JaxWsPortProxyFactoryBean();
69. bean.setServiceInterface(LoginService.class);
70. bean.setServiceName("PPLoginService");
71. bean.setWsdlDocumentUrl(new URL("http://127.0.0.1:6644/user/login?wsdl"));
72. //设置超时
73. bean.addCustomProperty("com.sun.xml.internal.ws.request.timeout", 20000);
74. bean.addCustomProperty("com.sun.xml.internal.ws.connect.timeout", 20000);
75. return bean;
76. }
77. }
