四、Struts2+Spring+jsp调用webservice接口

1、书写Action类名为：Struts2ClientAction.java。源码如下：(返回复杂结果集转成json。)

package com.itcast.struts2.client; 
import com.itcast.cxf.first.IHelloWorld; 
import com.opensymphony.xwork2.ActionSupport; 
/** 
 * Struts2访问WebService 
 * @author wangjianme 
 */ 
public class Struts2ClientAction extends ActionSupport{ 
    private static final long serialVersionUID = 1L; 
    private IHelloWorld hello;      //注入属性 
    private String name;            //用户输入的姓名 
    public String getName() { 
        return name; 
    } 
    public void setName(String name) { 
        this.name = name; 
    } 
    public IHelloWorld getHello() { 
        return hello; 
    } 
    public void setHello(IHelloWorld hello) { 
        this.hello = hello; 
    } 
    public String execute() throws Exception { 
        name = getHello().sayHello(getName());          //远程调用 
        return SUCCESS; 
    } 
} 

package com.itcast.struts2.client;
import com.itcast.cxf.first.IHelloWorld;
import com.opensymphony.xwork2.ActionSupport;
/**
 * Struts2访问WebService
 * @author wangjianme
 */
public class Struts2ClientAction extends ActionSupport{
 private static final long serialVersionUID = 1L;
 private IHelloWorld hello;  //注入属性
 private String name;      //用户输入的姓名
 public String getName() {
  return name;
 }
 public void setName(String name) {
  this.name = name;
 }
 public IHelloWorld getHello() {
  return hello;
 }
 public void setHello(IHelloWorld hello) {
  this.hello = hello;
 }
 public String execute() throws Exception {
  name = getHello().sayHello(getName());   //远程调用
  return SUCCESS;
 }

2、applicationContext.xml的最终源代码如下

?<?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 address="http://localhost:9999/cxf2.4_spring_web/ws/helloworld" 
                  serviceClass="com.itcast.cxf.first.IHelloWorld" 
                  id="helloService"> 
    </jaxws:client>    
    <!-- 配置Action --> 
    <bean id="Struts2ClientAction"  
          class="com.itcast.struts2.client.Struts2ClientAction"  
          scope="prototype"> 
        <property name="hello" ref="helloService"></property> 
    </bean> 
</beans> 

<?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 address="http://localhost:9999/cxf2.4_spring_web/ws/helloworld"
               serviceClass="com.itcast.cxf.first.IHelloWorld"
               id="helloService">
 </jaxws:client> 
 <!-- 配置Action -->
 <bean id="Struts2ClientAction"
    class="com.itcast.struts2.client.Struts2ClientAction"
    scope="prototype">
  <property name="hello" ref="helloService"></property>
 </bean>
</beans>

、配置struts.xml文件的源代码如下：

?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> 
    <package name="com.itcast" extends="struts-default" namespace="/"> 
        <action name="struts2client" class="Struts2ClientAction"> 
            <result>/jsps/result.jsp</result> 
        </action> 
    </package> 
</struts> 

<?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>
 <package name="com.itcast" extends="struts-default" namespace="/">
  <action name="struts2client" class="Struts2ClientAction">
   <result>/jsps/result.jsp</result>
  </action>
 </package>
</struts>

4、jsps/struts2.jsp的源代码如下：

%@ page language="java" contentType="text/html; charset=UTF-8"%> 
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> 
<html> 
  <head> 
  </head> 
  <body> 
    <form action="<c:url value='/struts2client.action'/>" method="post"> 
    <label for="name">输入姓名：</label> 
    <input type="text" name="name" id="name"/> 
    <br/> 
    <input type="submit" value="确定"/> 
    </form> 
  </body> 
</html> 

<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
  <head>
  </head>
  <body>
    <form action="<c:url value='/struts2client.action'/>" method="post">
    <label for="name">输入姓名：</label>
    <input type="text" name="name" id="name"/>
    <br/>
    <input type="submit" value="确定"/>
    </form>
  </body>
</html>

5、jsps/result.jsp页面如下

%@ page language="java" contentType="text/html; charset=UTF-8"%> 
<%@ taglib uri="/struts-tags" prefix="s"%> 
<html> 
  <head> 
  </head> 
  <body> 
        <s:property value="name"/> 
  </body> 
</html> 

<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<html>
  <head>
  </head>
  <body>
     <s:property value="name"/>
  </body>
</html>

 

 

补充：Web开发 , 其他 ,

上一个：五、js调用webservice接口
下一个：三、spring+cxf调用webservice接口
