【WebService】WebService之CXF和Spring整合（六）

　　前面介绍了WebService与CXF的使用，项目中我们经常用到Spring，这里介绍CXF与Spring整合

步骤

　　1、创建一个Maven Web项目，可以参照：【Maven】Eclipse 使用Maven创建Java Web项目

　　2、添加spring依赖和cxf依赖的jar包，在pom文件中设置依赖即可

         </plugins>
         <finalName>test-webservice-cxf-spring</finalName>
     </build>

 </project>

　　

　　3、新建一个接口，使用@WebService（SEI和SEI的实现类）注解标注接口，使用@WebMethod（SEI中的所有方法）注解标注接口中定义的所有方法，如下：

 package com.test.ws;

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

 /**
  * 定义SEI(WebService EndPoint Interface)终端
  * @author H__D
  * @date 2017年7月28日 上午11:35:34
  *
  */
 //使用@WebService注解标注WebServiceI接口
 @WebService
 public interface HelloWS {

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

 }

　　4、编写一个接口实现类，使用@WebService注解标注实现类，如下：

 package com.test.ws;

 import javax.jws.WebService;

 /**
  * SEI的具体实现
  * @author H__D
  * @date 2017年7月28日 上午11:37:43
  *
  */
 //使用@WebService注解标注
 @WebService
 public class HelloWSImpl implements HelloWS{

     @Override
     public String sayHello(String name) {
         System.out.println("WebService sayHello : " + name);
         return "Hello : " + name;
     }
 }

　　5、编辑web.xml文件

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://java.sun.com/xml/ns/javaee"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
     id="WebApp_ID" version="3.0">
     <display-name>test-webservice-cxf-spring</display-name>

     <!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 -->
     <context-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>classpath:spring/spring-context.xml</param-value>
     </context-param>

     <!-- Spring配置 -->
     <listener>
         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
     </listener>

     <!--cxfservlet的作用就是解析webservice请求 -->
     <servlet>
         <servlet-name>cxf</servlet-name>
         <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
         <load-on-startup>1</load-on-startup>
     </servlet>
     <!-- 所有前缀为ws的请求都被解析为webservice请求 -->
     <servlet-mapping>
         <servlet-name>cxf</servlet-name>
         <url-pattern>/ws/*</url-pattern>
     </servlet-mapping>

     <welcome-file-list>
         <welcome-file>index.jsp</welcome-file>
     </welcome-file-list>
 </web-app>

　　6、在src/main/resources中新建一个文件夹spring，在spring文件夹中新建一个spring-content.xml的配置文件和一个cxf的webservice配置文件（cxf-beans.xml），进行相关配置
　　　　
　　　　spring-content.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:mvc="http://www.springframework.org/schema/mvc"
     xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
     xmlns:util="http://www.springframework.org/schema/util" xmlns:aop="http://www.springframework.org/schema/aop"
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
         http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-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/util http://www.springframework.org/schema/util/spring-util-4.0.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-4.0.xsd">

     <!-- 注解注册 -->
     <context:annotation-config />

     <context:component-scan base-package="com.test" />

     <!-- 引入cxf的webservice配置文件 -->
     <import resource="classpath:spring/cxf-beans.xml" />

 </beans>

　　　　cxf-beans.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.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

     <!-- 引cxf的一些核心配置 -->
     <import resource="classpath:META-INF/cxf/cxf.xml" />
     <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

     <!-- 定义webservice服务，相当于发布 -->
     <jaxws:server id="HelloWS" address="/helloWS"
         serviceClass="com.test.ws.HelloWS">
         <!--发布服务类 -->
         <jaxws:serviceBean>
             <bean class="com.test.ws.HelloWSImpl"></bean>
         </jaxws:serviceBean>

         <!-- 输入拦截器 -->
         <jaxws:inInterceptors>
              <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean>
          </jaxws:inInterceptors>

          <!-- 输出拦截器 -->
          <jaxws:outInterceptors>
              <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"></bean>
          </jaxws:outInterceptors>
     </jaxws:server>

 </beans>

　　7、搭建完成，如下图
　　　　　　　

　　8、发布到tomcat中，并启动tomcat
　　　　　　

　　9、使用浏览器访问获取wsdl文件，或者进行webservice调用都行
