基于CXF搭建webService的实例讲解

1.导入相关jar包，具体哪些包我记不太清了

2.在applicationContext中加入相关配置信息，如下所示：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jaxws="http://cxf.apache.org/jaxws"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
              http://www.springframework.org/schema/beans/spring-beans-3.0.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">

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

    <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="OrderWS"
      implementor="com.cxf.spring.ws.OrderWSImpl"//类所在地址或者#+对应bean的id
      address="/OrderWS" > //随意命名
      <jaxws:features>
       <bean class="org.apache.cxf.feature.LoggingFeature" />
      </jaxws:features>
    </jaxws:endpoint>
</beans>

3.在web.xml文件中加入：

<!-- cxf配置 -->
   <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>/CXFServlet/*</url-pattern>
  </servlet-mapping>

4.在service层加入：

@WebService
public interface OrderWS {
  @WebMethod
  public Order getOrderById(int id);
}

5.若存在struts2，会发生冲突，则重写过滤器

5.1 写一个类ExtendStrutsFilter：

package com.nbu.retailer.filter;

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;

public class ExtendStrutsFilter extends StrutsPrepareAndExecuteFilter{
  private static Logger log = LoggerFactory.getLogger(ExtendStrutsFilter.class);
  @Override
  public void doFilter(ServletRequest req, ServletResponse res,FilterChain chain)
      throws IOException, ServletException {
      try {
        HttpServletRequest request = (HttpServletRequest) req;
        // 判断是否是向WebService发出的请求
        if (request.getRequestURI().contains("/CXFServlet")) {
           // 如果是来自向CXFService发出的请求
           chain.doFilter(req, res);
         }
         else {
           // 默认action请求
            super.doFilter(req, res, chain);
         }
       }
      catch (Exception e) {
         log.error(e.getMessage());
         e.printStackTrace();
      }
  }

}

5.2 在web.xml中改变过滤器的地址：

<!-- struts2的过滤器-->
   <filter>
    <filter-name>struts2</filter-name>
    <!--
      <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    -->
    <!-- 自定义struts2过虑器类 用于解决struts2把cxf的请求当action处理的问题-->
    <filter-class>com.nbu.retailer.filter.ExtendStrutsFilter</filter-class>
  </filter>

5.3 注意，CXF的url和struts2的url不能相同。之前就这个问题困扰了我好久才发现的。
