最简单的cxf restful webservice Demo（包括与spring集成）

package pojo;

import java.util.Date;

import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "student")
public class Student {

private long id;
private String name;
private Date birthday;

public long getId() {
return id;
}

public void setId(long 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;
}

}

package service;

import javax.jws.WebService;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import pojo.Student;

@WebService
@Path("/student")
public interface StudentService {

@GET
@Path("query/{id}")
@Produces(MediaType.APPLICATION_JSON)//这里可以自行定义返回的数据格式json xml等
public Student queryStudent(@PathParam("id")long id);
}

package service;

import java.util.Date;

import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;

import pojo.Student;

public class StudentServiceImpl implements StudentService {
@Override
public Student queryStudent(long id) {
Student student=new Student();
student.setId(1);
student.setName("yang");
student.setBirthday(new Date());
return student;
}
//为了省事直接在此类运行一个main方法发布服务
public static void main(String[] args) {
JAXRSServerFactoryBean JaxRSServerFactoryBean=new JAXRSServerFactoryBean();
JaxRSServerFactoryBean.setAddress("http://127.0.0.1:12347/rest");
JaxRSServerFactoryBean.setServiceBean(new StudentServiceImpl());
JaxRSServerFactoryBean.setResourceClasses(StudentServiceImpl.class);
JaxRSServerFactoryBean.create();

}
}

浏览器访问http://127.0.0.1:12347/rest/student/query/001
返回json格式数据
{"student":{"birthday":"2015-12-15T10:29:06.381+08:00","id":1,"name":"yang"}}

与spring集成

将该web项目发布到tomcat下 访问该URL   http://localhost:8080/cxf_restful/ws/restful/student/query/001 
返回结果

所需jar包不方便提供大家自行下载
