Web Service——CXF+Spring 整合

结合spring框架来实现CXF发布SOAP协议的服务，步骤基本相同，所不同的是的多了一些配置项，步骤如下

1. 服务端

第一步：创建web项目（引入jar包）

第二步：创建SEI接口

import javax.jws.WebService;
import javax.xml.ws.BindingType;
import javax.xml.ws.soap.SOAPBinding;

@WebService
@BindingType(SOAPBinding.SOAP12HTTP_BINDING)
public interface WeatherInterface {

    public String QueryWeather(String cityName);
}

第三步：创建SEI实现类

public class WeatherInterfaceImpl implements WeatherInterface {

    @Override
    public String QueryWeather(String cityName) {
        System.out.println("from client..." + cityName);
        if ("北京".equals(cityName)) {
            return "晴转多云";
        } else {
            return "雨转小雪";
        }
    }
}

第四步：配置spring配置文件，applicationContext.xml，用<jaxws:server>标签发布服务，设置1.服务地址；2.设置服务接口；3.设置服务实现类

<?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"
    xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:cxf="http://cxf.apache.org/core"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                            http://www.springframework.org/schema/beans/spring-beans.xsd
                            http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd
                            http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
                            http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">

    <!-- <jaxws:server发布SOAP协议的服务 ，对JaxWsServerFactoryBean类封装-->
    <jaxws:server address="/weather" serviceClass="com.zang.ws.cxf.server.WeatherInterface">
        <jaxws:serviceBean>
            <ref bean="weatherInterface"/>
        </jaxws:serviceBean>

        <!-- 配置拦截器 -->
        <jaxws:inInterceptors>
            <ref bean="inIntercepter"/>
        </jaxws:inInterceptors>
        <jaxws:outInterceptors>
            <ref bean="outIntercepter"/>
        </jaxws:outInterceptors>
    </jaxws:server>
    <!-- 配置拦截器的bean -->
    <bean name="inIntercepter" class="org.apache.cxf.interceptor.LoggingInInterceptor"/>
    <bean name="outIntercepter" class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>

    <!-- 配置服务实现类 -->
    <bean name="weatherInterface" class="com.zang.ws.cxf.server.WeatherInterfaceImpl"/>
</beans>                  

第五步：配置web.xml，配置spring配置文件地址和加载的listener，配置CXF的servlet。

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    id="WebApp_ID" version="3.1">
    <display-name>ws_cxf_spring_server</display-name>

    <!-- 设置spring的环境 -->
    <context-param>
        <!--contextConfigLocation是不能修改的 -->
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- 配置CXF的Servlet -->
    <servlet>
        <servlet-name>CXF</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>CXF</servlet-name>
        <url-pattern>/ws/*</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

第六步：部署到tomcat下，启动tomcat

第七步：测试服务，阅读使用说明书  地址： http://localhost:8089/ws_cxf_spring_server/ws/weather?wsdl

如果直接创建实现类，可以使用Endpoint标签发布服务。步骤如下

创建实现类

@WebService
public class HelloWorld {
    public String sayHello(String name){
        return "hello,"+name;
    }
}

之前通过创建SEI接口实现时，applicationContext.xml中是用<jaxws:server>标签来发布服务；而直接通过创建类来实现时，applicationContext.xml中应使用<jaxws:endpoint>标签来发布服务。

<!-- <jaxws:endpoint发布SOAP协议的服务 ，对Endpoint类封装-->
<jaxws:endpoint address="/hello" implementor="com.zang.ws.cxf.server.HelloWorld"/>    

重启tomcat，访问说明书  http://localhost:8089/ws_cxf_spring_server/ws/hello?wsdl

2. 客户端

第一步：引入jar包

第二步：生成客户端代码  wsdl2java命令，详见客户端实现

第三步：配置spring配置文件，applicationContent.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"
    xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:cxf="http://cxf.apache.org/core"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                            http://www.springframework.org/schema/beans/spring-beans.xsd
                            http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd
                            http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
                            http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">

    <!-- <jaxws:client实现客户端 ，对JaxWsProxyFactoryBean类封装 -->
    <jaxws:client id="weatherClient"
        address="http://127.0.0.1:8089/ws_cxf_spring_server/ws/weather"
        serviceClass="com.zang.cxf.weather.WeatherInterface" />
</beans>                  

第四步：从spring上下文件获取服务实现类，调用查询方法，打印

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.zang.cxf.weather.WeatherInterface;

public class WeatheClient {

    public static void main(String[] args) {
        // 初始化spring的上下文
        ApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
　　　　 // 调用查询方法
        WeatherInterface weatherInterface = (WeatherInterface) context.getBean("weatherClient");
        String weather = weatherInterface.queryWeather("济南");
        System.out.println(weather);
    }
}
