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
