CXF WebService整合SpringMVC的maven项目

首先推荐博客：http://www.cnblogs.com/xdp-gacl/p/4259481.html

CXF是webService技术的一种实现工具，为什么用CXF来实现webService：

1.      Java的webService实现本身就是一个很耗性能的实现方案（xml与java对象之间在服务端以及客户端的互转比较消耗性能）；

2.      目前java主流的webService应用以CXF、AXIS2为主；

3.      通过网络渠道的了解,目前CXF的效率要比AXIS2高出至少50%；

4.      另外有一个webService的工具metro的效率比CXF高出10%；

5.      CXF的实现资料网上可以随便找出一大堆，metro的资料相对少一些；

6.      CXF在java应用实现中已经很成熟，企业更倾向于用这样一个成熟的解决方案；

基于以上原因，我选择CXF来实现webService。

CXF WebService整合SpringMVC：

1、web.xml 作如下修改：

<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>/webservice/*</url-pattern>
</servlet-mapping>

2、引用CXF

下载cxf工具包。解压CXF之后，把cxf工具包lib下的jar包全部放到工程的lib下。此处用到的cxf工具包版本为：apache-cxf-2.7.13，或者maven引用：

<!-- 在properties中注明CFX的版本 -->
<properties>
        <!-- spring版本号 -->
	<spring.version>4.0.2.RELEASE</spring.version>
	<!-- mybatis版本号 -->
	<mybatis.version>3.2.6</mybatis.version>
	<!-- log4j日志文件管理包版本 -->
	<slf4j.version>1.7.7</slf4j.version>
	<log4j.version>1.2.17</log4j.version>
	<!-- webService -->
	<cxf.version>2.7.13</cxf.version>
</properties>

3、spring.xml中配置

<?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:context="http://www.springframework.org/schema/context"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"
	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://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx.xsd
	http://www.springframework.org/schema/aop
	http://www.springframework.org/schema/aop/spring-aop.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-3.0.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"/> 

   <jaxws:endpoint id="orderWebService" address="/orderWebService"
          implementor="com.bsit.webservice.impl.OrderWebServiceImpl" />
<bean id="client" class="com.bsit.webservice.OrderWebServiceI"
          factory-bean="clientFactory" factory-method="create"/>
    <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
         <property name="serviceClass" value="com.bsit.webservice.OrderWebServiceI"/>
         <property name="address" value="http://192.168.1.20:8080/order/webservice/orderWebService?wsdl"/>
    </bean>

</beans>

4、接口及实现类

　　定义一个interface，使用@WebService注解标注接口，使用@WebMethod注解标注接口中定义的所有方法；实现类，使用@WebService注解标注实现类，实现接口中定义的所有方法（注意@WebService(endpointInterface="接口的包名.接口名", serviceName="服务名")中的配置），如下所示：

//接口
package com.bsit.webservice;

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

import com.bsit.orders.model.Orders;

@WebService
public interface OrderWebServiceI {

	//使用@WebMethod注解标注WebServiceI接口中的方法
	@WebMethod
	String sayHello(@WebParam(name="name") String name);

	@WebMethod
	Orders getOrdersByNum(String num);

}

//实现类
package com.bsit.webservice.impl;

import javax.jws.WebService;

import org.springframework.beans.factory.annotation.Autowired;

import com.bsit.orders.mapper.OrdersMapper;
import com.bsit.orders.model.Orders;
import com.bsit.webservice.OrderWebServiceI;

@WebService(endpointInterface="com.bsit.webservice.OrderWebServiceI",serviceName="OrderWebService")
public class OrderWebServiceImpl implements OrderWebServiceI{

	@Autowired
	private OrdersMapper ordersMapper;

	@Override
	public String sayHello(String name) {
		System.out.println("WebService sayHello " + name);
		return "Hello " + name + ", nice to meet you.";
	}

	@Override
	public Orders getOrdersByNum(String num) {
		Orders orders = ordersMapper.getOrdersBySalesNum(num);　　//数据库操作，ordersMapper注入

　　　　　　　　　 System.out.println(orders.getSales_order_num()); 

　　　　　　　　　 return orders; 
　　　　 } 
}

5、简单效果

　　启动tomcat，webservice随之启动，浏览器中输入：http://192.168.1.20:8080/order/webservice，

表示webservice服务已经启动。左边是暴漏出来的接口的方法名，点击右方的WSDL的链接，可以查看方法的具体参数信息：也可以直接输入：http://192.168.1.20:8080/order/webservice/orderWebService?wsdl，打开下图

6、测试

　　一、

package org.bsit.webService;

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

import com.bsit.orders.model.Orders;
import com.bsit.webservice.OrderWebServiceI;

public class OrderWebService1Test {

	/*
	 * 客户端调用webService的方法，如果spring.xml中配置了红色部分，则调用时factory.getBean("client")，强制转换成webService的接口
	*/
	@Test
	public void testOrderWebService(){
		ApplicationContext factory = new ClassPathXmlApplicationContext("/spring.xml");
		//转换OrderWebServiceI
		OrderWebServiceI client = (OrderWebServiceI)factory.getBean("client");

		Orders orders = new Orders();
		orders = client.getOrdersByNum("BS20160331-2");
		System.out.println(orders.getId() + ", " + orders.getSales_order_num());
	}
}

　　二、

package org.bsit.webService;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.bsit.orders.model.Orders;
import com.bsit.webservice.OrderWebServiceI;

public class OrderWebService2Test {

	private OrderWebServiceI orderWebService;

	/*
	 * 客户端调用webService的方法，如果spring.xml中没有配置红色部分，则调用时先写initParam()的初始化
	<jaxws:endpoint id="orderWebService" address="/orderWebService"
      	implementor="com.bsit.webservice.impl.OrderWebServiceImpl" />
	*/
	@Before
    　　 public void initParam(){
        　　JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
        　　factoryBean.setServiceClass(OrderWebServiceI.class);
        　　factoryBean.setAddress("http://192.168.1.20:8080/order/webservice/orderWebService?wsdl");  

        　　orderWebService = (OrderWebServiceI)factoryBean.create();
    　　}

	@Test
	public void testOrderWebService(){
		Orders orders = new Orders();
		orders = orderWebService.getOrdersByNum("BS20160331-2");
		System.out.println(orders.getId() + ", " + orders.getSales_order_num());
	}
}

7、结果：

　　控制台打印：73ccfffc-e7a3-468e-ba7d-5dc75e67886f, BS20160331-2；

　　说明webService中注入mapper成功，可以进行数据库查询，简单的字符串例子没做测试。

　　当然，这里既可以java调用webService，也可以其他程序如.net调用。
