import javax.jws.WebService;import com.sivalabs.caas.domain.AuthenticationStatus;
import com.sivalabs.caas.domain.Credentials;
import com.sivalabs.caas.exceptions.AuthenticationServiceException;WebService
public interface AuthenticationService
{
public AuthenticationStatus authenticate(Credentials credentials) throws AuthenticationServiceException;
}package com.sivalabs.caas.domain;
/*** author siva**/
public class Credentials
{private String userName;private String password;public Credentials()
{}public Credentials(String userName, String password) {super();this.userName userName;this.password password;}//setters and getters}package com.sivalabs.caas.domain;/*** author siva**/
public class AuthenticationStatus
{private String statusMessage;private boolean success;//setters and getters}package com.sivalabs.caas.exceptions;/*** author siva**/
public class AuthenticationServiceException extends RuntimeException
{private static final long serialVersionUID 1L;public AuthenticationServiceException(){}public AuthenticationServiceException(String msg){super(msg);}
} 现在让我们实现AuthenticationService。 package com.sivalabs.caas.services;import java.util.HashMap;
import java.util.Map;import javax.jws.WebService;import com.sivalabs.caas.domain.AuthenticationStatus;
import com.sivalabs.caas.domain.Credentials;
import com.sivalabs.caas.exceptions.AuthenticationServiceException;/*** author siva**/
WebService(endpointInterfacecom.sivalabs.caas.services.AuthenticationService,serviceNameAuthenticationService, targetNamespacehttp://sivalabs.blogspot.com/services/AuthenticationService)
public class AuthenticationServiceImpl implements AuthenticationService
{private static final Mapstring, string CREDENTIALS new HashMapstring, string();static{CREDENTIALS.put(admin, admin);CREDENTIALS.put(test, test); }Overridepublic AuthenticationStatus authenticate(Credentials credentials) throws AuthenticationServiceException{if(credentials null){throw new AuthenticationServiceException(Credentials is null);}AuthenticationStatus authenticationStatus new AuthenticationStatus();String userName credentials.getUserName();String password credentials.getPassword();if(userNamenull || userName.trim().length()0 || passwordnull || password.trim().length()0){authenticationStatus.setStatusMessage(UserName and Password should not be blank);authenticationStatus.setSuccess(false);}else{if(CREDENTIALS.containsKey(userName) password.equals(CREDENTIALS.get(userName))){authenticationStatus.setStatusMessage(Valid UserName and Password);authenticationStatus.setSuccess(true);}else{authenticationStatus.setStatusMessage(Invalid UserName and Password);authenticationStatus.setSuccess(false);}}return authenticationStatus;}
} 为了简单起见我们在此根据存储在HashMap中的静态数据检查凭据。 在实际的应用程序中将根据数据库进行此检查。 现在我们将发布WebService。 package com.sivalabs.caas.publisher;import javax.xml.ws.Endpoint;import com.sivalabs.caas.services.AuthenticationServiceImpl;public class EndpointPublisher
{public static void main(String[] args){Endpoint.publish(http://localhost:8080/CAAS/services/AuthenticationService, new AuthenticationServiceImpl());}} 运行此独立的类以发布AuthenticationService。 要检查服务是否已成功发布请将浏览器指向URL http// localhost8080 / CAAS / services / AuthenticationServicewsdl。 如果该服务成功发布您将看到WSDL内容。 现在让我们创建一个独立测试客户端来测试Web服务。 package com.sivalabs.caas.client;import java.net.URL;import javax.xml.namespace.QName;
import javax.xml.ws.Service;import com.sivalabs.caas.domain.AuthenticationStatus;
import com.sivalabs.caas.domain.Credentials;
import com.sivalabs.caas.services.AuthenticationService;/*** author siva**/
public class StandaloneClient
{public static void main(String[] args) throws Exception{URL wsdlUrl new URL(http://localhost:8080/CAAS/services/AuthenticationService?wsdl);QName qName new QName(http://sivalabs.blogspot.com/services/AuthenticationService, AuthenticationService);Service service Service.create(wsdlUrl,qName);AuthenticationService port service.getPort(AuthenticationService.class);Credentials credentialsnew Credentials();credentials.setUserName(admin1);credentials.setPassword(admin);AuthenticationStatus authenticationStatus port.authenticate(credentials);System.out.println(authenticationStatus.getStatusMessage());credentials.setUserName(admin);credentials.setPassword(admin);authenticationStatus port.authenticate(credentials);System.out.println(authenticationStatus.getStatusMessage());}} 不用我们自己编写StandaloneClient我们可以使用wsimport命令行工具生成Client。 wsimport工具在JDK / bin目录中。 转到项目的src目录然后执行以下命令。 wsimport -keep -p com.sivalabs.caas.client http// localhost8080 / CAAS / services / AuthenticationServicewsdl 它将在com.sivalabs.caas.client软件包中生成以下Java和类文件。 Authenticate.java AuthenticateResponse.java AuthenticationService_Service.java AuthenticationService.java AuthenticationServiceException_Exception.java AuthenticationServiceException.java AuthenticationStatus.java Credentials.java ObjectFactory.java 包信息.java 现在您可以使用生成的Java文件来测试服务。 public static void main(String[] args) throws Exception
{AuthenticationService_Service service new AuthenticationService_Service();com.sivalabs.caas.client.AuthenticationService authenticationServiceImplPort service.getAuthenticationServiceImplPort();com.sivalabs.caas.client.Credentials credentials new com.sivalabs.caas.client.Credentials();credentials.setUserName(admin1);credentials.setPassword(admin);com.sivalabs.caas.client.AuthenticationStatus authenticationStatus authenticationServiceImplPort.authenticate(credentials);System.out.println(authenticationStatus.getStatusMessage());credentials.setUserName(admin);credentials.setPassword(admin);authenticationStatus authenticationServiceImplPort.authenticate(credentials);System.out.println(authenticationStatus.getStatusMessage());
} 现在我们将看到如何在Tomcat服务器上部署JAX-WS WebService。 我们将在apache-tomcat-6.0.32上部署在http://sivalabs.blogspot.com/2011/09/developing-webservices-using-jax-ws.html中开发的AuthenticationService。 要部署我们的AuthenticationService我们需要添加以下配置。 1.web.xml web-applistenerlistener-classcom.sun.xml.ws.transport.http.servlet.WSServletContextListener/listener-class/listenerservletservlet-nameauthenticationService/servlet-nameservlet-classcom.sun.xml.ws.transport.http.servlet.WSServlet/servlet-classload-on-startup1/load-on-startup/servletservlet-mappingservlet-nameauthenticationService/servlet-nameurl-pattern/services/AuthenticationService/url-pattern/servlet-mapping
/web-app 2.创建一个新文件WEB-INF / sun-jax-ws.xml ?xml version1.0 encodingUTF-8?
endpointsxmlnshttp://java.sun.com/xml/ns/jax-ws/ri/runtimeversion2.0endpointnameAuthenticationServiceimplementationcom.sivalabs.caas.services.AuthenticationServiceImplurl-pattern/services/AuthenticationService//endpoints 3.从http://jax-ws.java.net/下载JAX-WS参考实现。 将所有jar文件从jaxws-ri / lib文件夹复制到WEB-INF / lib。 现在将应用程序部署在Tomcat服务器上。 您不需要像使用EndpointPublisher那样由我们自己发布服务。 Tomcat启动并运行后请在http// localhost8080 / CAAS / services / AuthenticationServicewsdl中查看生成的wsdl。 现在如果您使用独立客户端测试AuthenticationService它将可以正常工作。 public static void testAuthenticationService()throws Exception
{URL wsdlUrl new URL(http://localhost:8080/CAAS/services/AuthenticationService?wsdl);QName qName new QName(http://sivalabs.blogspot.com/services/AuthenticationService, AuthenticationService);Service service Service.create(wsdlUrl,qName);AuthenticationService port service.getPort(AuthenticationService.class);Credentials credentialsnew Credentials();credentials.setUserName(admin);credentials.setPassword(admin);AuthenticationStatus authenticationStatus port.authenticate(credentials);System.out.println(authenticationStatus.getStatusMessage());
} 但是如果尝试使用wsimport工具生成的客户端代码进行测试请确保在客户端类路径中没有jax-ws-ri jar。 否则您将得到以下错误 Exception in thread main java.lang.NoSuchMethodError: javax.xml.ws.WebFault.messageName()Ljava/lang/String;at com.sun.xml.ws.model.RuntimeModeler.processExceptions(RuntimeModeler.java:1162)at com.sun.xml.ws.model.RuntimeModeler.processDocWrappedMethod(RuntimeModeler.java:898) 参考 “ 我的实验”博客上的 JCG合作伙伴 Siva Reddy提供了使用JAX-WS开发WebServices和在Tomcat-6上部署JAX-WS WebService的信息 。 翻译自: https://www.javacodegeeks.com/2012/03/web-services-with-jax-ws-on-tomcat.htmljax-rs jax-ws
