• webservice总结之cxf


    java webservice有很多种实现方式,处理方式一般有两种:

      a:基于SOAP的 JAX-WS(Java API for XML-Based Web Services) 比如:RI,Axis,CXF

      b:基于REST的JAX-RS 比如Jersey,RESTEasy,CXF

    可以看到CXF 不仅用于开发基于 SOAP 的 WS,也开发于开发基于 REST 的 WS,那就来总结一下CXF的具体用法吧。

    SOAP 风格写法

    1,定义接口

    import javax.jws.WebService;
    
    @WebService
    public interface HelloFacade {
        String sayHello(String msg);
    
    }

    2,服务端实现接口与发布

     a, 实现接口:

    import javax.jws.WebService;
    
    import org.springframework.stereotype.Component;
    
    import com.bresume.core.ws.HelloFacade;
    
    @WebService
    @Component
    public class HelloFacadeImpl implements HelloFacade{
    
        @Override
        public String sayHello(String msg) {
            System.out.println("msg="+msg);
            return msg+"_success";
        }
    
    }
    HelloFacadeImpl

     b, web.xml配置:

        <!-- CXF -->
        <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>
    web.xml

     c,spring配置:

      最好将ws配置文件单独放置,引入

     <import resource="spring-cxf.xml"/>

      建立spring-cxf.xml   jaxws:server 或者 jaxws:endpoint 两种配置方式都可以

    <?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:context="http://www.springframework.org/schema/context"
        xmlns:jaxws="http://cxf.apache.org/jaxws"
        xsi:schemaLocation="http://www.springframework.org/schema/beans  
                            http://www.springframework.org/schema/beans/spring-beans-3.2.xsd  
                            http://www.springframework.org/schema/context 
                             http://www.springframework.org/schema/context/spring-context-3.2.xsd 
                             http://cxf.apache.org/jaxws
                               http://cxf.apache.org/schemas/jaxws.xsd">
    
    
    
    
        <!-- <jaxws:server id="helloFacade" address="/soap/hello">
            <jaxws:serviceBean>
                <ref bean="helloFacadeImpl" />
            </jaxws:serviceBean>
        </jaxws:server>
     -->
     
     <jaxws:endpoint id="helloFacade" implementor="#helloFacadeImpl" address="/soap/hello"/>
    
    </beans>

    服务端配置完毕,访问wsdl,可看到如下内容,则表示服务端配置成功

    3,客户端访问

    import org.apache.cxf.endpoint.Client;
    import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
    import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
    
    import com.bresume.core.ws.HelloFacade;
    
    public class Test {
        static final String url = "http://localhost:8081/ws/soap/hello";
    
        public static void main(String[] args) {
            testJaxWsClient();
            //testDynamicClient();
        }
    
        public static void testJaxWsClient () {
            JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
            factory.setAddress(url);
            factory.setServiceClass(HelloFacade.class);
    
            HelloFacade hellofacade = factory.create(HelloFacade.class);
            String result = hellofacade.sayHello("word");
            System.out.println("testJaxWsClient"+result);
        }
    
        public static void testDynamicClient() {
            JaxWsDynamicClientFactory  factory = JaxWsDynamicClientFactory .newInstance();
            Client client = factory.createClient("http://localhost:8081/ws/soap/hello?wsdl");
    
            try {
                Object[] results = client.invoke("sayHello", "world");
                System.out.println("DynamicClientFactory"+results[0]);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
    Test
