Apache CXF实战之一 Hello World Web Service
这篇文章介绍一下怎么通过CXF来发布RESTful的Web Service.
1. 首先是实体类,注意其中的@XmlRootElement注解
- 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);
- }
- }
2. RESTful Web Service接口类,可以通过修改@Produces注解来声明暴露接口返回的json还是xml数据格式
- 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);
- }
3. RESTful Web Service接口实现类
- 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;
- }
- }
4. Server端代码
- 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();
- }
- }
5. Client端代码
- 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));
- }
- }
6.测试首先运行MyServer类,然后运行MyClient类来验证Web Service。
