Spring整合CXF之发布WebService服务

今天我们来讲下如何用Spring来整合CXF，来发布WebService服务；

 

给下官方文档地址：http://cxf.apache.org/docs/writing-a-service-with-spring.html

 

根据官方文档。我们把前面的实例用Spring整合CXF来处理下。会简化很多；

 

首先我们来建一个Maven项目 WebService_CXF

 

建好项目第一步，我们打开pom.xml

我们来添加下Spring支持：

<!-- 添加Spring支持 -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>4.1.7.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>4.1.7.RELEASE</version>
</dependency>
<dependency>
     <groupId>org.springframework</groupId>
     <artifactId>spring-tx</artifactId>
     <version>4.1.7.RELEASE</version>
    </dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>4.1.7.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>4.1.7.RELEASE</version>
</dependency>
 
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>4.1.7.RELEASE</version>
</dependency>
 
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>4.1.7.RELEASE</version>
</dependency>
 
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>4.1.7.RELEASE</version>
</dependency>
 
 
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aspects</artifactId>
    <version>4.1.7.RELEASE</version>
</dependency>
 
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>4.1.7.RELEASE</version>
</dependency>

　　接下来添加下CXF支持：

<!-- 添加cxf支持  -->
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-core</artifactId>
    <version>3.1.5</version>
</dependency>
 
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-frontend-jaxws</artifactId>
    <version>3.1.5</version>
</dependency>
 
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-transports-http</artifactId>
    <version>3.1.5</version>
</dependency>

　　我们在项目里添加下 applicationContext.xml spring配置文件 我们要额外添加下命名路径，因为我们要用新的标签；

<beans xmlns="http://www.springframework.org/schema/beans"    
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
    xmlns:p="http://www.springframework.org/schema/p"  
    xmlns:aop="http://www.springframework.org/schema/aop"   
    xmlns:context="http://www.springframework.org/schema/context"  
    xmlns:jee="http://www.springframework.org/schema/jee"  
    xmlns:tx="http://www.springframework.org/schema/tx"  
    xmlns:jaxws="http://cxf.apache.org/jaxws"
    xsi:schemaLocation="    
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd  
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd  
        http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd  
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

　　这里的我是参考官方文档上，添加了 jaxws支持。。大家直接贴下即可；

然后我们再导入下cxf里的一些bean配置，参考官方文档：

<import resource="classpath:META-INF/cxf/cxf.xml"/>
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>

　　（我看了cxf核心包，其实质疑偶cxf.xml，没有cxf-servlet.xml 估计是兼容前面版本）

Spring配置文件里，我加下扫描：

<!-- 自动扫描 -->
<context:component-scan base-package="com.java1234.webservice" />

　　面搞完后，我们在处理下web.xml文件 首先启动的时候，必须加载Spring：

<!-- Spring配置文件 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>
 
<!-- Spring监听器 -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

　　然后我们要定义一个Servlet，主要是处理WebService请求：

<servlet>  
 <servlet-name>CXFServlet</servlet-name>  
 <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>  
</servlet>  
 
<servlet-mapping>  
   <servlet-name>CXFServlet</servlet-name>  
   <url-pattern>/webservice/*</url-pattern>  
</servlet-mapping>

　　这里的话，我们所有的 /webservice请求，都交给CXFServlet类处理；

最后一步，我们在Spring配置文件里，定义下webservice接口发布：

<!-- 定义服务提供者  -->
<jaxws:endpoint
    implementor="#helloWorld"
    address="/HelloWorld"
 ></jaxws:endpoint>

　　

这里implementor指定webservice接口实现类

address是具体的接口路径

 

最终完整的applicationContext.xml配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <import resource="classpath:META-INF/cxf/cxf.xml"/>
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
     
    <!-- 自动扫描 -->
    <context:component-scan base-package="com.java1234.webservice" />
     
    <!-- 定义服务提供者  -->
    <jaxws:endpoint
        implementor="#helloWorld"
        address="/HelloWorld"
     ></jaxws:endpoint>
</beans>
