Spring整合CXF之发布WebService服务

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

<!-- 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><!-- 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source里添加下 applicationContext.xml spring配置文件 

<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">

然后我们再applicationContext.xml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"/>

把之前类放到项目里 并且在HelloWorldImpl实现类里 加上 @Component("HelloWorld")

Spring配置文件里，我加下扫描：

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

前面搞完后，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"> <!-- 添加in拦截器 -->    <jaxws:inInterceptors>         <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/>         <bean class="com.gcx.interceptor.MyInterceptor"/>    </jaxws:inInterceptors>    <!-- 添加out拦截器 -->    <jaxws:outInterceptors>         <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/>    </jaxws:outInterceptors> </jaxws:endpoint>

最终完整的applicationContext.xml配置文件如下

<?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: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">            <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.gcx.webservice" /><!-- 定义服务提供者  --><jaxws:endpoint    implementor="#helloWorld"    address="/HelloWorld"> <!-- 添加in拦截器 -->    <jaxws:inInterceptors>         <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/>         <bean class="com.gcx.interceptor.MyInterceptor"/>    </jaxws:inInterceptors>    <!-- 添加out拦截器 -->    <jaxws:outInterceptors>         <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/>    </jaxws:outInterceptors> </jaxws:endpoint></beans>

最后启动项目访问 http://localhost:8080/WebService_CXF/webservice/ 

访问具体的接口： http://localhost:8080/WebService_CXF/webservice/HelloWorld?wsdl
