Apache-cxf2.5 + spring DEMO/code-优快云博客

本文详细介绍了如何利用CXF框架构建企业级Web服务，包括服务接口设计、实现和服务调用流程。通过提供的代码示例，展示了UserService接口及其实现类UserServiceImpl的结构，以及客户端如何通过CXF进行服务调用。此外，还提供了Spring配置文件示例，确保服务能够在应用中正常运行。

cxf的作用、优点和缺点网上很多，请自行了解。

建立web项目 cxf 结构如下图

下面是代码:

User

package demo.cxf;

import java.util.Date;

public class User {
	private Date birthday;
	private int height;
	private String password;
	private String sex;
	private String sign;
	private String username;

	public Date getBirthday() {
		return birthday;
	}

	public void setBirthday(Date birthday) {
		this.birthday = birthday;
	}

	public int getHeight() {
		return height;
	}

	public void setHeight(int height) {
		this.height = height;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String getSex() {
		return sex;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}

	public String getSign() {
		return sign;
	}

	public void setSign(String sign) {
		this.sign = sign;
	}

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

}

UserService

package demo.cxf;

import javax.jws.WebService;

@WebService
public interface UserService {
	public void changeUserState(User user, int state);

	public boolean checkUserExists(String username);

	public void createUser(User user);

	public void cusumePremiumPoint(String username, int points);

	public void deleteUser(String username) throws NotFoundException;

	public void increasePremiumPoint(String username, int points);

	public void updateUserInformation(User user);
}

UserServiceImpl

package demo.cxf;

import javax.jws.WebService;
/**
 * 
 * @author Administrator
 * @date 2011-12-11
 * 
 */
/*
 * @WebService，必选的标注。用于导出的服务接口及其实现类
 * endpointInterface	指定服务接口的Java类。通常用于服务实现类的标注。应当指定类的全名，如demo.cxf.UserService
 * serviceName	定义服务名，与名域一起唯一标识一个服务。默认是其Java类名
 */
@WebService(endpointInterface = "demo.cxf.UserService", serviceName = "/UserService")
public class UserServiceImpl implements UserService{

	public void changeUserState(User user, int state) {
		print("changeUserState"); 
	}
	public boolean checkUserExists(String username) {
		print("checkUserExists");
		return false;
	}
	public void createUser(User user) {
		print("createUser");
		print(user.getUsername());
	}
	public void cusumePremiumPoint(String username, int points) {
		print("consumePremiumPoint");
	}
	public void deleteUser(String username) throws NotFoundException {
		throw new NotFoundException("我故意没找到");
	}
	public void increasePremiumPoint(String username, int points) {
		print("increasePremiumPoint");
	}
	public void updateUserInformation(User user) {
		print("updateUserInformation");
	}
	private void print(Object o) {
		System.out.println(o);
	}

}

NotFoundException

package demo.cxf;

public class NotFoundException extends Exception {
	/**
	 * 
	 */
	private static final long serialVersionUID = 5356795954914115184L;

	public NotFoundException() {
		super();
	}

	public NotFoundException(String message, Throwable cause) {
		super(message, cause);
	}

	public NotFoundException(String message) {
		super(message);
	}

	public NotFoundException(Throwable cause) {
		super(cause);
	}
}

Client

package demo.cxf;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

public class Client {
	private static  void deleteUser(String username) throws NotFoundException{
		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
		factory.setServiceClass(UserService.class);
		factory.setAddress("http://localhost:8080/cxf/services/UserService");
		UserService client = (UserService)factory.create();
		client.deleteUser(username);
	}
	
	public static void main(String[] args) {
		try {
			Client.deleteUser("lin");
		} catch (NotFoundException e) {
			e.printStackTrace();
		}	
	}
}
