Web Service学习-CXF与Spring整合为JavaEE应用发布WebService(三)

jopen 8年前

CXFSpring整合,分两个方面给大家介绍:

 

1,在传统ssh项目基础上添加Web Service

赋值CXFjar

web.xml配置文件中导入CXF的核心控制器:CXFServlet

Spring配置文件中导入CXF提供Schemaxml配置文件

Spring配置文件中使用jaxws:endpoint元素来暴露Web Service

如果要添加拦截器,在jaxws:endpoint元素里添加

inInterceptors,outInterceptors子元素

2,远程调用Web Service服务(让Action依赖远程Web Service的接口)

复制CXFjar

Spring配置文件中导入CXF提供Schemaxml配置文件

Spring配置文件中使用jaxws:client元素来配置远程Web Service代理

如果要添加拦截器。在jaxws:client元素里添加

inInterceptors,outInterceptors子元素

 

第一个方面:提供Web Service的服务


服务端:

 

项目结构:




在相应的SSH项目中添加CXF的相关jar包:




Web.xml


<?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"   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"   version="2.5">   <listener>            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>        </listener>            <context-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/applicationContext-common.xml</param-value>        </context-param>          <!--所有来自/*的请求,都交由 CXFServlet来处理-->      <servlet>            <servlet-name>HelloWorldService</servlet-name>            <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>            <load-on-startup>1</load-on-startup>        </servlet>        <servlet-mapping>            <servlet-name>HelloWorldService</servlet-name>            <url-pattern>/*</url-pattern>        </servlet-mapping>         </web-app>

applicationContext-common.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">       <import resource="classpath:META-INF/cxf/cxf.xml" />        <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />        <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />            <bean id="helloWorld" class="com.tgb.service.impl.HelloWorldImpl">       <property name="userService" ref="userService"></property>      </bean>          <!-- 用户的Service -->          <bean id="userService" class="com.tgb.service.impl.UserServiceImpl">             </bean>   <!-- implementor指定webservice的服务提供者 -->   <!-- address为wsdl的访问地址 -->      <jaxws:endpoint id="hello" implementor="#helloWorld" address="/hjy" >    <!-- 添加了2个In拦截器,如果不添加拦截器可直接注释掉如下代码 -->    <jaxws:inInterceptors>     <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/>     <bean class="com.tgb.auth.AuthInterceptor"/>    </jaxws:inInterceptors>    <!-- 如果要配置Out拦截器,使用outInterceptors -->   </jaxws:endpoint>  </beans>

以上配置已经完成,对于接口和相应的实现参考之前的博客即可,实现中对于new的内容使用spring管理起来

 

HelloWorldImpl:

package com.tgb.service.impl;    import java.util.Date;  import java.util.List;  import java.util.Map;    import javax.jws.WebService;    import com.tgb.domain.Cat;  import com.tgb.domain.User;  import com.tgb.service.HelloWorld;  import com.tgb.service.UserService;    @WebService(endpointInterface="com.tgb.service.HelloWorld",serviceName="HelloWorldImpl")  public class HelloWorldImpl implements HelloWorld{     private UserService userService;      public UserService getUserService() {    return userService;   }     public void setUserService(UserService userService) {    this.userService = userService;   }     public String sayHi(String name) {         return name+"您好!现在时间为:"+new Date();   }      @Override   public List<Cat> getCatsByUser(User user) {    //在实际项目中,web service组件自己并不会去实现业务功能    //它只是调用业务逻辑组件的方法来暴露web service  //  UserService us=new UserServiceImpl();        return userService.getCatsByUser(user);   }     @Override   public Map<String, Cat> getAllCats() {  //  UserService us=new UserServiceImpl();    return userService.getAllCats();   }       }

启动tomcat服务器:

新建客户端项目CXF_Spring_Client,生成客户端代码:




注意:

有些版本拷贝后,类中的super()会出错,要加上-frontendjaxws21,参看如上截图

 

客户端调用:


package com.tgb.client;    import java.util.List;    import org.apache.cxf.endpoint.Client;  import org.apache.cxf.frontend.ClientProxy;    import com.tgb.auth.AddHeaderInterceptor;  import com.tgb.service.Cat;  import com.tgb.service.HelloWorld;  import com.tgb.service.User;  import com.tgb.service.impl.HelloWorldImpl;    public class client {     public static void main(String[] args){    HelloWorldImpl factory=new HelloWorldImpl();    //此处返回的只是远程Web Service的代理    HelloWorld hw=factory.getHelloWorldImplPort();        /**     * 添加的拦截器     */    Client client=ClientProxy.getClient(hw);    //参数为输入的用户名,密码    client.getOutInterceptors().add(new AddHeaderInterceptor("hejingyuan","hjy"));            System.out.println(hw.sayHi("hejingyuan"));      System.out.println("--------------------------");        User user=new User();    user.setId(20);    user.setName("孙悟空");    user.setPass("111");    user.setAddress("花果山");        List<Cat> cats=hw.getCatsByUser(user);    for(Cat cat:cats){     System.out.println(cat.getName());    }        System.out.println("--------------------------");        System.out.println(hw.getAllCats().getEntry().get(0).getKey());    System.out.println(hw.getAllCats().getEntry().get(0).getValue().getName());       }  }



由于我们在服务端添加了拦截器,故客户端必须要添加相应的拦截器给服务端提供参数,否则客户端调用失败




另一个方面:调用远程的Web Service服务

 

新建客户端项目CXF_Spring_Web_Client,生成客户端代码




web.xml

<?xml version="1.0" encoding="UTF-8"?>  <web-app version="2.5" 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_2_5.xsd">      <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>/WEB-INF/applicationContext.xml</param-value>   </context-param>   <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>   </listener>      <filter>    <filter-name>struts2</filter-name>    <filter-class>     org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>   </filter>   <filter-mapping>    <filter-name>struts2</filter-name>    <url-pattern>/*</url-pattern>   </filter-mapping>         </web-app>

applicationContext.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">          <import resource="classpath:META-INF/cxf/cxf.xml" />   <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />   <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />      <bean id="listCatsAction" class="com.tgb.action.ListCatsAction">    <property name="helloWorld" ref="helloWorld"></property>   </bean>        <!-- 配置远程webservice代理 -->   <!-- id="helloWorld"对应 action setHelloWorld() -->   <jaxws:client id="helloWorld"    serviceClass="com.tgb.service.HelloWorld"    address="http://localhost:8080/CXF_Spring_Server/hjy">    <jaxws:outInterceptors>    <!-- 配置输出拦截器  -->      <bean class="com.tgb.auth.AddHeaderInterceptor" >      <constructor-arg value="hejingyuan"/>      <constructor-arg value="hjy"/>     </bean>    </jaxws:outInterceptors>   </jaxws:client>     </beans>

Struts.xml


<?xml version="1.0" encoding="UTF-8" ?>  <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">  <struts>     <package name="default" namespace="/" extends="struts-default">    <action name="listCats" class="com.tgb.action.ListCatsAction" >     <result name="SUCCESS">/WEB-INF/page/listcats.jsp</result>    </action>   </package>  </struts>

调用代码:

package com.tgb.action;    import org.apache.cxf.endpoint.Client;  import org.apache.cxf.frontend.ClientProxy;    import com.opensymphony.xwork2.ActionSupport;  import com.tgb.auth.AddHeaderInterceptor;  import com.tgb.service.HelloWorld;      public class ListCatsAction extends ActionSupport{        private HelloWorld helloWorld;       public HelloWorld getHelloWorld() {    return helloWorld;   }     public void setHelloWorld(HelloWorld helloWorld) {    this.helloWorld = helloWorld;   }     @Override   public String execute() throws Exception {    /**     * 添加的拦截器     */    Client client=ClientProxy.getClient(helloWorld);    //参数为输入的用户名,密码    client.getOutInterceptors().add(new AddHeaderInterceptor("hejingyuan","hjy"));    helloWorld.sayHi("hejingyuan");        return "SUCCESS";   }     }

最终的项目结构:




总结:


     以上与Spring的整合,概括的说,在应用Spring的框架过程中,一种是我们如何对外提供服务,另一种是我们如何获取已经提供好的服务。在整个过程中,只有几个关键点,很简单,但是要注意jar包的版本问题。
