【WebService框架-CXF】——CXF+Spring+Struts+自定义拦截器构建WebService客户端

　　在上一篇博客中我们总结了在SSH架构的服务端项目中添加Web Service层，并发布服务。这篇文章中，我们将介绍如何结合Spring构建WebService的客户端。

步骤

1.新建Java Web Project
2.引入Spring，Struts，CXF的相关Jar包。
这里写图片描述
3.通过java2wsdl命令生成客户端代理
链接地址为http://localhost:8080/CXF_Spring/webservice/HelloWorldWS?wsdl

4.编写Action，调用服务

public class ListCatAction extends ActionSupport  {    private HelloWorld hw;    private Map<String,Cat> cats=new HashMap<String, Cat>();    public Map<String, Cat> getCats() {        return cats;    }    public void setCats(Map<String, Cat> cats) {        this.cats = cats;    }    public void setHw(HelloWorld hw) {        this.hw = hw;    }    @Override    public String execute() throws Exception {        StringCat sc=hw.getAllCats();        if(sc!=null && sc.getEntries()!=null){            for(Entry e:sc.getEntries()){                            cats.put(e.getKey(), e.getValue());                           }        }          return "SUCCESS";    }}

将Action配置到struts.xml中

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd"><struts>    <constant name="struts.enable.DynamicMethodInvocation" value="false" />    <constant name="struts.devMode" value="false" />        <package name="struts2" extends="struts-default">        <action name="ListCatAction" class="ListCatAction">            <result name="SUCCESS">/WEB-INF/ListCats.jsp</result>        </action>    </package>   </struts>

ListCats.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><%@ taglib prefix="s" uri="/struts-tags" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>All the cats</title></head><body><s:iterator value="cats" var="entry">    <li>${entry.key}-->${entry.value.name}</li></s:iterator></body></html>

将Action交由Spring来管理。

<?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:aop="http://www.springframework.org/schema/aop"         xmlns:tx="http://www.springframework.org/schema/tx"         xmlns:jaxws="http://cxf.apache.org/jaxws"          xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.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="ListCatAction" class="com.tgb.action.ListCatAction">      <property name="hw" ref="hw"></property>  </bean></beans>

5.在applicationContext.xml中配置拦截器

  <jaxws:client id="hw"  serviceClass="com.tgb.ws.HelloWorld"   address="http://localhost:9009/HelloWorldWS"    >      <jaxws:outInterceptors>        <bean class="com.tgb.ws.auth.AddHeaderInterceptor">            <constructor-arg value="1"></constructor-arg>            <constructor-arg value="123"></constructor-arg>        </bean>    </jaxws:outInterceptors>  </jaxws:client>

总结

这里不同于服务端的配置就是使用<jaxws:client>标签。
