cxf框架和spring mvc的集成

cxf和spring mvc的集成

Apache CXF 是一个开源的 Services 框架，CXF 支持多种 Web Services 标准，包含 SOAP、Basic Profile、WS-Addressing、WS-Policy、WS-ReliableMessaging 和 WS-Security。

Spring MVC是通过DispatcherServlet来加载Spring配置文件的，因此不需要在web.xml中配置ContextLoaderListener。但是CXF却需要通过ContextLoaderListener来加载Spring。 

这样就产生了一个矛盾，如果不配置ContextLoaderListener，CXF就无法正常使用。但如果配置ContextLoaderListener，又会造成Spring的重复加载（DispatcherServlet一次，ContextLoaderListener一次） 

在网上查了一下资料，只看到一个国外的程序员提出不配置ContextLoaderListener，通过写一个CXFController，来替代默认的CXFServlet。但是这种HACK的方式总是不太好 

所以我采用一种折中的方式，来解决Spring MVC和cxf并存的问题。但是也不是很优雅，希望有人能给出更好的办法 

首先是web.xml的配置 

<?xml version="1.0" encoding="UTF-8"?><web-app id="WebApp_ID" version="3.0" 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_3_0.xsd">    <!--<absolute-ordering/>-->    <!-- 配置spring-servlet的控制容器 -->    <servlet>        <servlet-name>springMVC</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/springMVC-servlet.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>springMVC</servlet-name>        <url-pattern>*.do</url-pattern>    </servlet-mapping>    <!-- 配置Spring监听 -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!-- 加载Spring主容器-->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>/WEB-INF/applicationContext.xml</param-value>    </context-param>    <!-- WebService配置CXF -->    <servlet>        <servlet-name>CXF-WebService</servlet-name>        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>        <load-on-startup>2</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>CXF-WebService</servlet-name>        <url-pattern>/webservice/*</url-pattern>    </servlet-mapping>    <welcome-file-list>        <welcome-file>/index.jsp</welcome-file>    </welcome-file-list></web-app>

在ContextLoaderListener里面，加载cxf和spring的公共配置信息。然后在DispatcherServlet中加载spring mvc所需的信息。利用Spring配置文件拆分的方式，既实现spring mvc和cxf的共存，又避免spring配置信息的重复加载

然后是spring公共配置信息：applicationContext.xml

<?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"       xsi:schemaLocation="http://www.springframework.org/schema/beans                            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd                              http://www.springframework.org/schema/context                               http://www.springframework.org/schema/context/spring-context-3.1.xsd                              http://www.springframework.org/schema/tx                              http://www.springframework.org/schema/tx/spring-tx-3.1.xsd                                                         http://camel.apache.org/schema/spring                              http://camel.apache.org/schema/spring/camel-spring.xsd ">       <import resource="cxf.xml"/>                                <context:component-scan base-package="com.webapp.service"/>                            <context:component-scan base-package="com.webapp.webservice"/></beans>

然后是cxf客户端所需的信息，cxf.xml 

<?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-3.1.xsd                              http://cxf.apache.org/jaxws                               http://cxf.apache.org/schemas/jaxws.xsd">       <bean id="propertyConfigurer"          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">          <property name="locations">              <list>                  <value>/WEB-INF/webservice_address.properties</value>              </list>          </property>      </bean>    
<!-- 客户端配置-->
    <jaxws:client id="Client" serviceClass="com.webapp.webservice.AssembleBillInterface"          address="${Client}" />        
<!-- 服务端配置
       <jaxws:endpoint id="helloWorld"             implementorClass="com.framework.webservice.HelloWorldImpl"          address="/allbillservice" />  -->
</beans> 

自定义配置信息：webservice_address.properties

Client = http://127.0.0.1:28081/datamanager/webservices/allbillservice?wsdl
springMvc 配置springMVC-servlet.xml
<?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:context="http://www.springframework.org/schema/context"          xmlns:mvc="http://www.springframework.org/schema/mvc"           xsi:schemaLocation="http://www.springframework.org/schema/beans                                  http://www.springframework.org/schema/beans/spring-beans-3.1.xsd                                  http://www.springframework.org/schema/context                                   http://www.springframework.org/schema/context/spring-context-3.1.xsd                                  http://www.springframework.org/schema/mvc                                http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">            <!--对controller包中进行扫描，完成Bean创建和自动依赖注入的功能-->      <context:component-scan base-package="com.webapp.controller"/>      <!-- 完成请求和注解POJO的映射 -->      <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>            <!-- Default ViewResolver -->      <bean id="viewResolver"            class="org.springframework.web.servlet.view.InternalResourceViewResolver">         <property name="viewClass"                    value="org.springframework.web.servlet.view.JstlView" />           <property name="prefix" value="/" />           <property name="suffix" value=".jsp"></property>      </bean></beans>
