  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。

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。
