WebService 学习笔记之 集成Spring和Web容器

一.开发环境

我的开发环境是：

MyEclipse 10

Tomcat 6.0

Apache cxf-2.3.0? 相关jar包下载地址： http://www.apache.org/dist/cxf/2.3.0/

二.开发步骤

? 创建Server

? 1.新建一个Web工程WebServiceDemo，并添加apache-cxf-2.3.0相关jar文件,然后建个com.demo包。在包里面创建HelloWorld接口

代码如下

package com.demo;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

@WebService  
public interface HelloWorld {
	@WebMethod
	@WebResult String sayHi(@WebParam String text);  

}

?

再创建一个类实现HelloWorld接口

package com.demo;

import javax.jws.WebService;

@WebService
public class HelloWorldImpl implements HelloWorld {

	public String sayHi(String text) {
		// TODO Auto-generated method stub
		return "Hi," + text;

	}

}

?

然后修改web.xml里面内容

<?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">
  <display-name></display-name>	
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
    <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>WEB-INF/beans.xml</param-value>  
   </context-param>  
  
  
    <listener>  
        <listener-class>  
            org.springframework.web.context.ContextLoaderListener  
        </listener-class>  
    </listener>  
  
    <servlet>  
        <servlet-name>CXFServlet</servlet-name>       
        <servlet-class>  
            org.apache.cxf.transport.servlet.CXFServlet  
        </servlet-class>  
       <load-on-startup>1</load-on-startup>  
    </servlet>  
  
    <servlet-mapping>  
       <servlet-name>CXFServlet</servlet-name>  
       <url-pattern>/*</url-pattern>  
   </servlet-mapping> 
</web-app>

?

在WEB-INF下面创建一个beans.xml

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"
    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" />

    <jaxws:endpoint id="helloWorld" implementor="com.demo.HelloWorldImpl" address="/HelloWorld" />
</beans>

?

将Web工程发布到Tomcat里面，然后启动Server

?

? 创建Client

? 接着创建客户端，在com.demo下面创建client-beans.xml。内容如下

<?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"
    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/schema/jaxws.xsd">

    <bean id="client" class="com.demo.HelloWorld"
        factory-bean="clientFactory" factory-method="create" />

    <bean id="clientFactory"
        class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
        <property name="serviceClass" value="com.demo.HelloWorld" />
        <property name="address" value="http://127.0.0.1:8080/WebServiceDemo/HelloWorld" />
    </bean>

</beans>

?

在创建测试类Client.java

package com.demo;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Client {
	public static Client self = new Client();
	private HelloWorld client = null;

	private Client() {
		ApplicationContext context = new ClassPathXmlApplicationContext(
				new String[] { "com/demo/client-beans.xml" });
		client = (HelloWorld) context.getBean("client");

	}

	public HelloWorld getServer() {
		return client;

	}

	public String getText(String text) throws Exception {
		String response = getServer().sayHi(text);
		return response;
	}

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		try {

			System.out.println(self.getText("cuiran"));
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

}

? 然后进行测试运行。如果遇到类似这种错误“AXB 2.1 API is being loaded from the bootstrap classloader”说明你的web工程添加了J2EE 1.4或者是1.5 library. 这样就与jaxb-api-2.2.1.jar

??冲突了，只需删除即可。

最后运行如图
