CXF入门

CXF是apache旗下的开源框架，由Celtix + XFire这两门经典的框架合成，是一套非常流行的web service框架。

它提供了JAX-WS的全面支持，并且可以根据实际项目的需要，采用代码优先（Code First）或者 WSDL 优先（WSDL First）来轻松地实现 Web Services 的发布和使用，同时它能与spring进行完美结合。

简单实例

创建接口：

import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;  
@XmlJavaTypeAdapter(ProjectAdapter.class)  
public interface Project \{  
public String getProjectName();  
public void setProjectName(String projectName);  
public String getProjectId();  
public void setProjectId(String projectId);  
public String getProjectDescribe();  
public void setProjectDescribe(String projectDesc);  
\}

实现接口：

import javax.xml.bind.annotation.XmlType;  
@XmlType(name="Project")  
public class ProjectImpl implements Project \{  
private String projectId;  
private String projectName;  
private String projectDescribe;  
  
public ProjectImpl() \{\}  
  
public String getProjectId() \{  
return projectId;  
\}  
public void setProjectId(String projectId) \{  
this.projectId = projectId;  
\}  
public String getProjectName() \{  
return projectName;  
\}  
public void setProjectName(String projectName) \{  
this.projectName = projectName;  
\}  
public String getProjectDescribe() \{  
return projectDescribe;  
\}  
public void setProjectDescribe(String projectDescribe) \{  
this.projectDescribe = projectDescribe;  
\}  
\}

业务处理：

import javax.jws.WebParam;  
import javax.jws.WebService;

//该处用到注解  
@WebService  
public interface ProjectManager \{  
public String greeting();  
public String greetingWithParameter(@WebParam(name="greet")String greet);  
public String getProjectName();  
public String getProjectNameById(String projectID);  
public void updataProjectName(@WebParam(name="projectName")String projectName);  
public void setDefaultProject(Project project);  
public void registerProject(Project project);  
public void removeProject(String id);  
public Project getDefaultProject();  
public void getAllProject();  
\}

实现：

import java.util.HashMap;  
import java.util.Map;  
import javax.jws.WebService;  
@WebService(  
serviceName="ProjectManager",  
portName="ProjectManagerPort",  
targetNamespace="http://webservices/cxf.demo/",  
endpointInterface="demo.cxf.webservices.ProjectManager"  
)  
public class ProjectManagerImpl implements ProjectManager \{  
  
private Project project;  
private Map<String, Project> projectMap;  
  
public ProjectManagerImpl() \{  
System.out.println("--------构造方法---------");  
initProject();  
\}  
private void initProject() \{  
System.out.println("开始初始化");  
project = new ProjectImpl();  
project.setProjectId("default projectId");  
project.setProjectName("default projectName");  
project.setProjectDescribe("default projectDesc");  
projectMap = new HashMap<String, Project>();  
Project project2 = new ProjectImpl();  
project2.setProjectId("projectId2");  
project2.setProjectName("projectName2");  
project2.setProjectDescribe("projectDesc2");  
  
projectMap.put(project.getProjectId(), project);  
projectMap.put(project2.getProjectId(), project2);  
\}  
public String greeting() \{  
System.out.println("---------greeting--------");  
return "Hello,this is ProjectManager.";  
\}  
public String greetingWithParameter(String greet) \{  
System.out.println("--------greetingWithParameter---------");  
return "Hello,"+greet+"this is ProjectManager.";  
\}  
public String getProjectName() \{  
System.out.println("---------getProjectName--------");  
return project.getProjectName();  
\}  
public String getProjectNameById(String projectID) \{  
System.out.println("---------getProjectNameById--------");  
if (!projectMap.containsKey(projectID)) \{  
return null;  
\}  
return projectMap.get(projectID).getProjectName();  
\}  
public void updataProjectName(String projectName) \{  
System.out.println("---------updataProjectName--------");  
project.setProjectName(projectName);  
\}  
public void setDefaultProject(Project project) \{  
System.out.println("---------setDefaultProject--------");  
if (project == null) \{  
return;  
\}  
this.project = project;  
\}  
public Project getDefaultProject()\{  
System.out.println("---------getDefaultProject--------");  
return project;  
\}  
public void registerProject(Project project) \{  
System.out.println("---------registerProject--------");  
if (projectMap.containsKey(project.getProjectId())) \{  
return;  
\}  
projectMap.put(project.getProjectId(), project);  
\}  
public void removeProject(String id) \{  
System.out.println("---------removeProject--------");  
if (!projectMap.containsKey(id)) \{  
return;  
\}  
projectMap.remove(id);  
\}  
public void getAllProject() \{  
System.out.println("--------getAllProject---------");  
for (Map.Entry<String, Project> crrentProject : projectMap.entrySet()) \{  
System.out.println(" "+crrentProject.getKey()+":"+crrentProject.getValue().getProjectName());  
\}  
\}  
public Project getProjectById(String projectId)\{  
System.out.println("----------getProjectById----------");  
if (!projectMap.containsKey(projectId)) \{  
return null;  
\}  
return projectMap.get(projectId);  
\}  
\}

服务端：

public class Server \{  
  
  
public Server() \{  
System.out.println("Starting Server");  
ProjectManager projectManager = new ProjectManagerImpl();  
String endPointAddress = "http://localhost:9000/ProjectManager";  
Endpoint.publish(endPointAddress, projectManager);  
\}  
  
public static void main(String\[\] args) throws Exception \{  
new Server();  
System.out.println("Server ready...");  
Thread.sleep(30\*6\*1000);  
System.out.println("Server exiting....");  
System.exit(0);  
\}  
\}

客户端：

import java.net.URL;  
import javax.xml.namespace.QName;  
import javax.xml.ws.Service;  
import demo.cxf.webservices.Project;  
import demo.cxf.webservices.ProjectImpl;  
import demo.cxf.webservices.ProjectManager;  
public class Client \{  
private static final QName SERVICE\_NAME = new QName("http://webservices.cxf.demo/", "ProjectManager");  
private static final QName PORT\_NAME = new QName("http://webservices.cxf.demo/", "ProjectManagerPort");  
private static final String WSDL\_LOCATION = "http://localhost:9000/ProjectManager?wsdl";  
public Client() \{  
\}  
public static void main(String\[\] args) throws Exception \{  
System.out.println("Starting Client....");  
URL wsdlUrl = new URL(WSDL\_LOCATION);  
Service service = Service.create(wsdlUrl,SERVICE\_NAME);  
ProjectManager projectManager = service.getPort(PORT\_NAME,ProjectManager.class);  
System.out.println(projectManager.getProjectName());  
Project project = new ProjectImpl();  
project.setProjectName("new projectName");  
projectManager.setDefaultProject(project);  
Project newProject = projectManager.getDefaultProject();  
System.out.println("NewProjectId is "+newProject.getProjectId()+".NewProjectName is "+newProject.getProjectName());  
projectManager.registerProject(project);  
System.out.println(projectManager.getProjectNameById("Default ProjectId"));  
System.out.println(projectManager.getProjectNameById("new ProjectId"));  
System.exit(0);  
\}  
\}
