這篇文章介紹一下怎麼通過CXF來發布RESTful的Web Service.

1. 首先是實體類，注意其中的@XmlRootElement註解

package com.googlecode.garbagecan.cxfstudy.jaxrs;import java.util.Date;import javax.xml.bind.annotation.XmlRootElement;@XmlRootElement(name="Customer") public class Customer {    private
 
 String id;    private String name;    private Date birthday;    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public
 
 Date getBirthday() {        return birthday;    }    public void setBirthday(Date birthday) {        this.birthday = birthday;    }    @Override    public String toString() {        return org.apache.commons.lang.builder.ToStringBuilder.reflectionToString(this);    }}

package
 
 com.googlecode.garbagecan.cxfstudy.jaxrs;import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.PathParam;import javax.ws.rs.Produces;import javax.ws.rs.QueryParam;@Path(value = "/customer") @Produces("*/*")//@Produces("application/xml")//@Produces("application/json")public interface CustomerService {    @GET    @Path(value = "/{id}/info")    Customer findCustomerById(@PathParam("id")String id);        @GET    @Path(value = "/search")    Customer findCustomerByName(@QueryParam("name")String name);}

package com.googlecode.garbagecan.cxfstudy.jaxrs;import java.util.Calendar;public class CustomerServiceImpl implements CustomerService {    public Customer findCustomerById(String id) {        Customer customer = new Customer();        customer.setId(id);        customer.setName(id);        customer.setBirthday(Calendar.getInstance().getTime());        return customer;    }        public Customer findCustomerByName(String name) {        Customer customer = new Customer();        customer.setId(name);        customer.setName(name);        customer.setBirthday(Calendar.getInstance().getTime());        return customer;    }}

package com.googlecode.garbagecan.cxfstudy.jaxrs;import org.apache.cxf.interceptor.LoggingInInterceptor;import org.apache.cxf.interceptor.LoggingOutInterceptor;import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;public class MyServer {    public static void main(String[] args) throws Exception {        JAXRSServerFactoryBean factoryBean = new JAXRSServerFactoryBean();        factoryBean.getInInterceptors().add(new LoggingInInterceptor());        factoryBean.getOutInterceptors().add(new LoggingOutInterceptor());        factoryBean.setResourceClasses(CustomerServiceImpl.class);        factoryBean.setAddress("http://localhost:9000/ws/jaxrs");        factoryBean.create();    }}

package com.googlecode.garbagecan.cxfstudy.jaxrs;import org.apache.commons.httpclient.HttpClient;import org.apache.commons.httpclient.HttpStatus;import org.apache.commons.httpclient.methods.GetMethod;public class MyClient {    public static void main(String[] args) throws Exception {        go("http://localhost:9000/ws/jaxrs/customer/1/info");        go("http://localhost:9000/ws/jaxrs/customer/search?name=abc");    }        private static void go(String url) throws Exception {        HttpClient client = new HttpClient();        GetMethod method = new GetMethod(url);        int statusCode = client.executeMethod(method);        if (statusCode != HttpStatus.SC_OK) {            System.err.println("Method failed: " + method.getStatusLine());        }        byte[] responseBody = method.getResponseBody();        System.out.println(new String(responseBody));    }}

首先執行MyServer類，然後執行MyClient類來驗證Web Service。
