Apache CXF实现WebService开发(一)

       Apache CXF 是一个开放源代码框架，提供了用于方便地构建和开发 Web 服务的可靠基础架构。它允许创建高性能和可扩展的服务，您可以将这样的服务部署在 Tomcat 和基于 Spring 的轻量级容器中，以及部署在更高级的服务器上，例如 Jboss、IBM? WebSphere? 或 BEA WebLogic。

基本环境搭建
        下载最新的CXF需要的jar文件，http://cxf.apache.org/download.html或者http://download.csdn.net/detail/ma_hoking/8210349。在这里我们不进行区分，将所有Apache CXF\apache-cxf-3.0.2\lib下的jar文件(不包含子目录下的文件)复制到项目下。在此我们新建一个Java Project项目CXFWebService，将前面所述的jar文件导入项目中。

创建自定义对象
注解：
@XmlRootElement-指定XML根元素名称（可选） 
@XmlAccessorType-控制属性或方法序列化 ， 四种方案： 

• FIELD-对每个非静态，非瞬变属性JAXB工具自动绑定成XML，除非注明XmlTransient 
• NONE-不做任何处理 
• PROPERTY-对具有set/get方法的属性进行绑定，除非注明XmlTransient 
• PUBLIC_MEMBER -对有set/get方法的属性或具有共公访问权限的属性进行绑定，除非注 明XmlTransient 

@XmlType-映射一个类或一个枚举类型成一个XML Schema类型

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

/**
 * 定义对象演示
 * @author mahc
 *
 */
@XmlRootElement(name="User")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder={"name","loginName","age"})
public class User {

	//请使用基本属性类型
	private String name;
	private String loginName;
	private int age;

	/**
	 * ※ 需要※       无参数默认构造器
	 */
	public User() {
		super();
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getLoginName() {
		return loginName;
	}

	public void setLoginName(String loginName) {
		this.loginName = loginName;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	public User(String name, String loginName, Integer age) {
		this.name = name;
		this.loginName = loginName;
		this.age = age;
	}

	@Override
	public String toString() {
		return "User [name=" + name + ", loginName=" + loginName + ", age="
				+ age + "]";
	}
	
}

import java.util.List;

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

import com.mahaochen.cxf.User;

/**
 * ※@WebService：申明为webservice的注解 
 *  endpointInterface：要暴露的接口类
 *  serviceName：服务名
 * @author mahc
 *
 */
@WebService(endpointInterface = "com.mahaochen.cxf.ws.IUserService", serviceName = "UserService")
public interface IUserService {

	/**
	 * ※@WebParam(name = "name"):自定义请求参数的名称
	 * @param name
	 * @param loginName
	 * @param age
	 * @return
	 */
	public User registerUser(
			@WebParam(name = "name") String name,
			@WebParam(name = "loginName") String loginName,
			@WebParam(name = "age") int age);
	
	public List<User> getRegistedUsers();

}

构建WebService的实现类

import java.util.ArrayList;
import java.util.List;

import com.mahaochen.cxf.User;

public class UserService implements IUserService{

	private static List<User> userList = new ArrayList<User>();
	
	@Override
	public User registerUser(String name, String loginName, int age) {
		
		User user = new User(name, loginName, age);
		userList.add(user);
		return user;
	}

	@Override
	public List<User> getRegistedUsers() {

		for(int i=0;i<2;i++){
			User tempUser = new User("name"+i, "loginName"+i, 18+i);
			userList.add(tempUser);
		}
		return userList;
	}

}

/**
 * 发布WebServie服务测试类
 * @author mahc
 *
 */
public class TestCXFWebService {

	public static void main(String[] args) {
		System.out.println("CXFWebService is starting!");
		IUserService userService = new UserService();
		String address = "http://localhost:8090/CXFWebService";
//		String testAddress = "http://localhost:8090/CXFWebService?wsdl";
		Endpoint.publish(address, userService);
		System.out.println("CXFWebService is started!");
	}
}

            以上是单独部署的方式之一，然而很多情况下，我们并不希望我们的WebService和我们的应用分开成两个服务器，而希望他们在同一个容器，Tomcat或JBOSS或其他的，这样我们就必须通过WEB来部署我们前面完成的webservice。这部分将在下篇博文中介绍，敬请期待！
