6.用CXF编写基于Spring的WebService

首先是服务器端:

//实体类
public class Weather {

    private String region;//区域编码
    private String regionName;//区域名称
    private float temperature;//温度
    private boolean isRain;//是否下雨

    public Weather() {
        super();
    }
    public Weather(String region, String regionName, float temperature,
            boolean isRain) {
        super();
        this.region = region;
        this.regionName = regionName;
        this.temperature = temperature;
        this.isRain = isRain;
    }
    
    public String getRegion() {
        return region;
    }
    public void setRegion(String region) {
        this.region = region;
    }
    public String getRegionName() {
        return regionName;
    }
    public void setRegionName(String regionName) {
        this.regionName = regionName;
    }
    public float getTemperature() {
        return temperature;
    }
    public void setTemperature(float temperature) {
        this.temperature = temperature;
    }
    public boolean isRain() {
        return isRain;
    }
    public void setRain(boolean isRain) {
        this.isRain = isRain;
    }
    
    @Override
    public String toString() {
        return "Weather [region=" + region + ", regionName=" + regionName
                + ", temperature=" + temperature + ", isRain=" + isRain + "]";
    }
}

//SEI
@WebService
public interface WeatherDao {

    //通过区域编码查找该地区天气情况
    @WebMethod
    Weather findWeatherByRegion(String region);
}

//SEI实现类
@WebService
public class WeatherService implements WeatherDao {

    @Override
    public Weather findWeatherByRegion(String region) {
        return new Weather("fjxm", "福建省厦门市", 20, true);
    }

}

//配置beans.xml
<?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:jaxws="http://cxf.apache.org/jaxws"
    xsi:schemaLocation="

    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
    
    <!-- cxf的一些核心配置(必须引入) -->
    <import resource="classpath:META-INF/cxf/cxf.xml" />
    <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />

    <!-- implementor:SEI实现类全类名 -->

        webService部署路径:主机名/工程名/address
        wsdl文档:通过主机名/工程名/address?wsdl
        不再需要手动去发布webService！
    -->
    <jaxws:endpoint id="weatherWS" 
        implementor="com.cxf.service.WeatherService"
        address="/weatherws" />
</beans>

//配置web.xml，spring文件随容器启动加载
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

//发布该工程，查看wsdl文档：

<?xml version='1.0' encoding='UTF-8'?><wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://service.cxf.com/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns2="http://schemas.xmlsoap.org/soap/http" xmlns:ns1="http://dao.cxf.com/" name="WeatherServiceService" targetNamespace="http://service.cxf.com/">

************至此，服务器端发布成功，接下来是客户端生成代码以及配置和测试****************

//配置客户端的client-beans.xml
<?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:jaxws="http://cxf.apache.org/jaxws"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://cxf.apache.org/jaxws
    http://cxf.apache.org/schemas/jaxws.xsd">
    
    <!-- serviceClass:SEI -->
    <!-- address:server端webService的发布地址 -->
    <jaxws:client id="weatherClient" 
        serviceClass="com.cxf.dao.WeatherDao" 
        address="http://localhost:8080/cxf_spring_webService_server/weatherws" />
</beans>

//生成客户端代码同cxf生成客户端代码步骤---略
//测试
public class Test {

    public static void main(String[] args) {
        //获取spring容器，自动创建WeatherDao实现类对象
        ClassPathXmlApplicationContext context =
                new ClassPathXmlApplicationContext("client-beans.xml");
        
        //client-beans.xml里的id
        WeatherDao weatherDao = (WeatherDao) context.getBean("weatherClient");
        Weather weather = weatherDao.findWeatherByRegion("fjxm");
        System.out.println(weather);
    }
}

执行结果：

Weather [rain=true, region=fjxm, regionName=福建省厦门市, temperature=20.0]
