webservice--cxf和spring结合,发布restFull风格的服务

Posted 2020-10-04 baorant

下面是发布一个restFull风格的实例：

服务端：

实体：

package entity;

import java.util.Date;

import javax.xml.bind.annotation.XmlRootElement;

/**
 * 实体
 */

@XmlRootElement(name="student")       
public class Pojo {
    
    private long id;
    //温度
    private String detail;
    //日期
    private Date  date;
    //最高
    private int temperature_max;
    //最低
    private int temperature_min;
    
    
    public long getId() {
        return id;
    }
    public void setId(long id) {
        this.id = id;
    }
    public String getDetail() {
        return detail;
    }
    public void setDetail(String detail) {
        this.detail = detail;
    }
    public Date getDate() {
        return date;
    }
    public void setDate(Date date) {
        this.date = date;
    }
    public int getTemperature_max() {
        return temperature_max;
    }
    public void setTemperature_max(int temperature_max) {
        this.temperature_max = temperature_max;
    }
    public int getTemperature_min() {
        return temperature_min;
    }
    public void setTemperature_min(int temperature_min) {
        this.temperature_min = temperature_min;
    }
    
    
}

一定要在实体类的前边加上annotation ，这样才能让信息在POJO和XML之间转换

 

SEI:

package service;

import java.util.List;

import javax.jws.WebParam;
import javax.jws.WebResult;
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 entity.Pojo;

/**
 * 接口
 */

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

    //MediaType
    
    //查询学生列表
    @GET
    @Path("/queryList/{type}")
    @Consumes(MediaType.APPLICATION_XML)
    public List<Pojo> queryWeather(@PathParam("type")String cityName);
    
    
    //查询学生
    @GET
    @Path("/query/{id}")
    @Produces({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
    public Pojo queryById(@PathParam("id")long id);
    
}

每个方法之前，要用annotation声明http请求的method类型，比如GET,DELETE,POST, PUT

 @Path("/room/{id}")中的id是一个参数，应该在方法的参数列表中声明：  public Pojo queryById(@PathParam("id")long id)

实现类：

 

package service;

import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.List;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

import com.sun.org.glassfish.gmbal.ParameterNames;

import entity.Pojo;

/**
 * 实现类
 */

public class Impl implements WeatherInterface {

    @Override
    public List<Pojo> queryWeather(String cityName) {
        
        List<Pojo> list = new ArrayList<Pojo>();
        
        //日历附件
        Calendar calendar = Calendar.getInstance();
        int day = calendar.get(Calendar.DATE);
        
        Pojo pojo1 = new Pojo();
        pojo1.setId(01);
        pojo1.setDetail("晴1");
        pojo1.setDate(new Date());
        pojo1.setTemperature_max(5);
        pojo1.setTemperature_min(-6);
        
        Pojo pojo2 = new Pojo();
        pojo2.setId(02);
        pojo2.setDetail("晴2");
        calendar.set(Calendar.DATE, day+1);
        pojo2.setDate(calendar.getTime());
        pojo2.setTemperature_max(5);
        pojo2.setTemperature_min(-6);
        
        Pojo pojo3 = new Pojo();
        pojo3.setId(003);
        pojo3.setDetail("晴3");
        calendar.set(Calendar.DATE, day+2);
        pojo3.setDate(calendar.getTime());
        pojo3.setTemperature_max(5);
        pojo3.setTemperature_min(-6);
        
        
        list.add(pojo1);
        list.add(pojo2);
        list.add(pojo3);
        
        return list;
    }

    @Override
    public Pojo queryById(long id) {
        Pojo pojo1 = new Pojo();
        pojo1.setId(id);
        pojo1.setDetail("张三");
        pojo1.setDate(new Date());
        pojo1.setTemperature_max(5);
        pojo1.setTemperature_min(-6);
        
        return pojo1;
    }


}
