使用cxf 发布 jax-rs 风格webservice 。并客户端测试。

详细介绍：http://www.ibm.com/developerworks/cn/java/j-lo-jaxrs/

1、定义一个User对象

package com.zf.test;


import java.util.Date;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="User")
public class User {
    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;
    }


}

2、编写Service接口

package com.zf.test;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;

@Path(value="/user")
@Produces(MediaType.TEXT_XML)  //指定返回给客户端的类型
@Consumes(MediaType.TEXT_XML)  //接收客户端来的类型
public interface IUserService {

    @GET
    @Path(value="/info/{id}")
    public User getUser(@PathParam("id") long id,@QueryParam("name") String name);

    @GET
    @Path(value="/info2")
    public User getUser(@QueryParam("name") String name);

    @POST
    @Path(value = "/info3")
    public User getUser(User user);

}

3、实现Service类

package com.zf.test;

import java.text.ParseException;
import java.text.SimpleDateFormat;

public class UserServiceImpl implements IUserService {

    public User getUser(long id,String name) {
        User user=new User();
        user.setId(id);
        user.setName(name);
        try {
            user.setBirthday(new SimpleDateFormat("yyyy-MM-dd").parse("1987-02-01"));
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return user;
    }

    public User getUser(String name) {
        User user=new User();
        user.setId(1);
        user.setName(name);
        try {
            user.setBirthday(new SimpleDateFormat("yyyy-MM-dd").parse("1985-03-01"));
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return user;
    }

    @Override
    public User getUser(User user) {
        System.out.println("getUser");
        if(user != null)
            System.out.println( user.getId() + " " + user.getName() + "  " + user.getBirthday().toLocaleString());
        else
            System.out.println("user is null!");
        return user;
    }

}

4、编写客户端

可以直接在浏览器中输入 http://localhost:9999/user/info/3?name=is_zhoufeng 访问。 在浏览器中会输出如下结果：

<User><birthday>1987-02-01T00:00:00+08:00</birthday><id>3</id><name>is_zhoufeng</name></User>

（下面的操作之前，应该在客户端生成对应的User类型。可以在服务端提供相应的xsd文件。给客户端生成。我这里直接将User复制过去了）

首先根据服务端 编写客户端Service接口

package com.zf.vo;

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;


@Path("/user")
@Produces(MediaType.TEXT_XML)
@Consumes(MediaType.TEXT_XML)
public interface UserService {

    @POST
    @Path("/info3")
    User info(User user);

    @GET
    @Path(value="/info2")
    User info2(String name) ;

}

访问GET方法

package com.zf.vo;
import org.apache.cxf.jaxrs.client.WebClient;

public class RestClient {
    public static void main(String[] args) {
        WebClient client=WebClient.create("http://127.0.0.1:5555/user/info/3?name=is_zhoufeng");
        User user=(User)client.accept("text/xml").get(User.class);
        System.out.println(user.getName());
    }
}

访问POST方法

package com.zf.vo;
import java.util.Date;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class PostRestClient {
    public static void main(String[] args) {
        ApplicationContext cxt = new ClassPathXmlApplicationContext(new String[]{"applicationContext.xml","jaxrs-https.xml"});
        UserService countriesService = (UserService)cxt.getBean("userService");
        User user = new User();
        user.setBirthday(new Date());
        user.setId(3);
        user.setName("is_zhoufeng");
        User u = countriesService.info(user);
        System.out.println(u.getId());
        System.out.println(u.getName());
        System.out.println(u.getBirthday().toLocaleString());
    }
}
