WebService 综合案例

1. 需求:

• 集成公网手机号归属地查询服务;
• 对外发布自己的手机号归属地查询服务;
• 提供查询界面

//1. 使用 wsimport 生成公网客户端代码
// 2. 创建 SEI 接口
    @WebService
    public interface MobileInterface{
        public String queryMobile(String phoneNum);
    }

// 3. 创建 SEI 实现类
    public class MobileImpl implements MobileInterface{
        // 公网服务客户端, 使用 Spring 注入
        private MobileCodeWSSoap mobileClient;
        public MobileCodeSWWoap getMobileClient(){
            return mobileClient;
        }
        public void setMobileClient(MobileCodeWSSoap mobileClient){
            this.mobileClient = mobileClient;
        }

        public String queryMobile(String phoneNum){
            // 调用公网服务客户端查询方法
            return mobileClient.getMobileCodeInfo(phoneNum,"");
        }
    }

// 4. 创建 queryMobile.jsp
  <form action="${pageContext.request.contextPath}/queryMobile.action" method="post">
    手机号码归属地查询:<input type="text" name="phoneNum"/><input type="submie" value="查询"/>
        <br/>
    查询结果:${result}
  </form>

// 5. 创建 MobileServlet.java
    public class MobileServlet extends HttpServlet{
        public void doPost(HttpServletRequest req, HttpServletResponse resp)
                    throws ServletException, IOException {
            String phoneNum = req.getParameter("phoneNum");
            if(null != phoneNum && !"".equals(phoneNum)){
                // 获取 Spring 框架中的内容
                ApplicationContext context =
                    WebApplicationContextUtils.getWebApplicationContext(this.getServletContext());
                // 获取 mobileServer 对象
                mobileServer = (MobileInterface)context.getBean("mobileServer");

                String result = mobileServer.queryMobile(phoneNum);
                request.setAttribute("result",result);
            }

            request.getRequest.Dispatcher("/jsp/queryMobile.jsp").forward(req,resp);
        }
    }

// 6. 配置 applicationContext.xml
    <!-- jaxws:server 发布服务 -->
    // 配置服务地址和服务接口
    <jaxws:server address="/mobile" serviceClass="cn.itcast.mobile.server.MobileInterface">
        <jaxws:serviceBean>
            <ref bean="mobileServer"/>
        </jaxws:serviceBean>
    </jaxws:server>

    <!-- 配置服务实现类 -->
    <bean name="mobileServer" class="cn.itcast.mobile.server.MobileImpl">
        <!-- 注入公网客户端 --
        <property name="mobileClient" ref="mobileClient"/>
    </bean>

    <!-- 配置公网客户端 -->
    <jaxws:client id="mobileClient" 
                address="http://ws.webxml.com.cn/WebServices/MobileCodeWS.asmx"
                serviceClass="cn.itcast.mobile.MobileCodeWSSoap"/>

// 7. 配置 web.xml
    // 参照 CXF+Spring 整合发布SOAP协议服务
    // 配置 MobileServlet
    <servlet>
        <servlet-name>mobileServlet</servlet-name>
        <servlet-class>cn.itcast.mobile.server.servlet.MobileServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>mobileServlet</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>
