用CXF发布Web服务

1.下载apache-cxf-2.7.6jar包,并把lib目录下的所有jar包导入项目

2.编写测试的实体类,示例如下:

package cn.bd.weather.entity;

import java.util.Date;

import javax.xml.bind.annotation.XmlRootElement;
/**
 * 
 * @author Administrator
 *   @XmlRootElement 表示根元素
 */
@XmlRootElement(name="Weather")   //name属性默认是类名
public class Weather {
    private String city;
    private Date date;
    private int min;
    private int max;
    private int average;
    private String desc;
    
    public Weather() {
        super();
    }
    public Weather(String city, Date date, int min, int max, int average,
            String desc) {
        super();
        this.city = city;
        this.date = date;
        this.min = min;
        this.max = max;
        this.average = average;
        this.desc = desc;
    }
    public String getCity() {
        return city;
    }
    public void setCity(String city) {
        this.city = city;
    }
    public Date getDate() {
        return date;
    }
    public void setDate(Date date) {
        this.date = date;
    }
    public int getMin() {
        return min;
    }
    public void setMin(int min) {
        this.min = min;
    }
    public int getMax() {
        return max;
    }
    public void setMax(int max) {
        this.max = max;
    }
    public int getAverage() {
        return average;
    }
    public void setAverage(int average) {
        this.average = average;
    }
    public String getDesc() {
        return desc;
    }
    public void setDesc(String desc) {
        this.desc = desc;
    }
    
}

3.编写服务接口,示例如下:

package cn.bd.weather.service;

import java.util.Date;
import java.util.List;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

import cn.bd.weather.entity.Weather;

@WebService(serviceName="WeatherService") //@WebService里面的targetNamespace="默认是包名"
public interface WeatherService {
    @WebResult(name="out")
    List<Weather> getWeathers(@WebParam(name="city")String city,@WebParam(name="dates")List<Date> dates);
    //@WebParam(name="city")表示city参数的别名
    
}

4.编写服务接口的实现,示例如下:

package cn.bd.weather.service.impl;

import java.util.ArrayList;
import java.util.Date;

import java.util.List;

import javax.jws.WebMethod;
import javax.jws.WebService;

import cn.bd.weather.entity.Weather;
import cn.bd.weather.service.WeatherService;

@WebService   //@WebService里面的targetNamespace=""
public class WeatherServiceImpl implements WeatherService {
    
    @WebMethod   //注解为web服务方法
    public List<Weather> getWeathers(String city, List<Date> dates) {
        List<Weather> list=new ArrayList<Weather>();
        for(Date date : dates){
            list.add(getWeather(city,date));
        }
        return list;
    }
    
    @WebMethod(exclude=true)  //exclude=true 表示这个web方法不对外暴露
    public Weather getWeather(String city,Date date){
        return new Weather(city,date,25,27,30,"晴");
    }

}

5.编写spring容器,示例如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:jaxws="http://cxf.apache.org/jaxws"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
                        http://cxf.apache.org/jaxws
10                         http://cxf.apache.org/schemas/jaxws.xsd
11                         http://cxf.apache.org/bindings/soap
12                         http://cxf.apache.org/schemas/configuration/soap.xsd">
    <!-- 引入CXF的文件 -->
    <import resource="classpath:META-INF/cxf/cxf.xml"/>
15     <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
16     <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
    
    <!-- 定义发布web服务的类 -->
    <bean id="weatherService" class="cn.bd.weather.service.impl.WeatherServiceImpl"></bean>
    
    <!-- 配置Endpoint   端口 -->
    <jaxws:endpoint id="wsServiceBean" implementor="#weatherService" address="getWeather" publish="true">
    </jaxws:endpoint>
    
    <!-- 
        如何查看web服务是否了布成功
        要在web.xml配置CXFServlet和装载spring容器
        1.起动tomcat,在浏览器输入localhost:8090/CXFService/getWeather  
29         其中getWeather 是配置Endpoint,属性address的值
     -->
</beans>

6.web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>    
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <context-param>
13       <param-name>contextConfigLocation</param-name>
14       <param-value>classpath:applicationContext.xml</param-value> <!-- 加载spring容器 -->
15   </context-param>
16   <listener>
17       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class><!-- 监听spring容器 -->
18   </listener>
  
  <!-- 配置CXFServlet -->
  <servlet>
22       <servlet-name>CXFServlet</servlet-name>
23       <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
24   </servlet>
25   <servlet-mapping>
26       <servlet-name>CXFServlet</servlet-name>
27       <url-pattern>/*</url-pattern>
28   </servlet-mapping>
  
</web-app>
