CXF框架构建和开发 Services

Apache CXF 是一个开源的 Services 框架,CXF 帮助您来构建和开发 Services 这些 Services 可以支持多种协议,比如:SOAP、POST/HTTP、RESTful HTTP CXF 大大简化了 Service可以天然地和 Spring 进行无缝集成。

ServerFactoryBean来发布web服务

服务类代码如下:

// 注解是无效的
@WebService(name="Hello",targetNamespace="http://icast.cn")
public class HelloWorld {
    public String sayHi(String name) {
        return "hello---->" + name;
    }
}

发布类代码如下:

public static void main(String[] args) {
        // 发布服务的类, 类似Endpoint
        ServerFactoryBean serverFactoryBean=new ServerFactoryBean();
        // 注册服务器地址和端口
        serverFactoryBean.setAddress("http://127.0.0.1:9999/hello");
        // 注册哪个类提供服务
        serverFactoryBean.setServiceBean(new HelloWorld());
        // 发布一个cxf服务
        serverFactoryBean.create();
// 一分钟有服务终止
        Thread.sleep(1 * 60 * 1000);
        // 正常退出程序
        System.exit(0);
}

ServerFactoryBean注意事项:

这种方式没有添加webService注解,也就是说没有注解也可以发布webService服务,但是这种方式不是很规范,比如我们不可以通过注解的方式来修改WSDL的标签信息,

CXF与Spring集成发布WebService

配置开发环境:

l  建立一个web项目

l  准备所有jar包,将CXF_HOME\lib项目下的所有jar包,全部都拷贝新项目的lib目录下.其中里面已经包含了Sring3.0的jar包  其中jetty 服务器的包可以不要.因为我们要部署的tomcat服务器中了

l  在web.xml中配置cxf的核心servlet,CXFServlet

l  此配置文件的作用类 拦截/ws/*的所有请求 类似Struts2的过滤器

<servlet>
        <servlet-name>cxf</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
<servlet-mapping>
        <servlet-name>cxf</servlet-name>
        <url-pattern>/ws/*</url-pattern>
</servlet-mapping>

通过Spring配置文件发布服务

<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"
    xmlns:jaxws="http://cxf.apache.org/jaxws" 
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
        http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd
        http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">    
    <!-- 这样配置自身的服务也可以使用 -->
    <bean id="userImpl" class="cn.loaderman.i.cxf.spring.ws.UserImpl" />
    <!-- id:逻辑名  serviceClass=服务接口类  address:调用的路径  http://localhost:8888/项目名/ws/hello?wsdl> -->
    <jaxws:server id="userService" serviceClass="cn.loaderman.i.cxf.spring.ws.IUser" address="/hello">
        <jaxws:serviceBean>
            <ref bean="userImpl" />
        </jaxws:serviceBean>
        <jaxws:inInterceptors>
            <bean class="org.apache.cxf.interceptor.LoggingInInterceptor" />
        </jaxws:inInterceptors>
        <jaxws:outInterceptors>
            <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor" />
        </jaxws:outInterceptors>
    </jaxws:server>
</beans>

服务接口如下:

@WebService
public interface IUser {
    public void saveUser(User user);
    public User getUser(int uid);
}

服务类如下:

public class UserImpl implements IUser {
    private List<User> users=new ArrayList<User>();

    public User getUser(int uid) {
        for(User temp:users){
            if(temp.getUid()==uid){
                return temp;
            }
        }
        return null;
    }
    public void saveUser(User user) {
        // TODO Auto-generated method stub
        users.add(user);
    }
}

实体类如下:

public class User {
    private int uid;
    private String uname;
    public int getUid() {
        return uid;
    }
    public void setUid(int uid) {
        this.uid = uid;
    }
    public String getUname() {
        return uname;
    }
    public void setUname(String uname) {
        this.uname = uname;
    }
}

通过JSP+Servlet调用本地服务:

Servlet在web.xml中配置如下:

<servlet>
        <servlet-name>cxf</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet>
        <servlet-name>UserServlet</servlet-name>
    <servlet-class>loaderman.i.cxf.servlet.UserServlet</servlet-clas>
    </servlet>

Servlet核心代码调用如下:

public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        User user = new User();
        user.setUid(Integer.parseInt(request.getParameter("uid")));
        user.setUname(request.getParameter("uname"));
        userImpl.saveUser(user);
    }
    public void init() throws ServletException {
        // Put your code here
        WebApplicationContext springContext = WebApplicationContextUtils
                .getWebApplicationContext(this.getServletContext());
        userImpl = (IUser) springContext.getBean("userImpl");
    } 

WEB页面调用代码如下:

<form action="/demo/servlet/UserServlet" method="post">
            用户编号:<input type="text" name="uid" /><br/>
            用户名:<input type="text" name="uname" /><br/>
            <input type="submit" value="提交" />
 </form>

通过Java远程调用访问CXF+Spring服务如下:

public static void main(String[] args) {
        IUserService userService=new IUserService();
        User user=new User();
        user.setUid(1);
        user.setUname("admin");
        userService.getIUserPort().saveUser(user);
        User temp=userService.getIUserPort().getUser(1);
        System.out.println(temp.getUid() + "|" + temp.getUname());
    }

通过ajax远程调用访问CXF+Spring服务如下:

<body>
        <button onclick="mobile()">cxf+Spring测试</button>
    </body>
    <script language="javascript">
        // 1:创建XMLHTTP对象
        var xhr=null;
        function mobile(){
            // 声明在访问的ws的地址
            var url="http://localhost:8888/day01/ws/hello";
            // 书写要发送的XML文件,即 SOAP
            var soap='<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body>' +
            '<ns2:getUser xmlns:ns2="http://ws.spring.cxf.i.loaderman.cn/"><arg0>1</arg0></ns2:getUser></soap:Body></soap:Envelope>';
            // 3:打开连接
            xhr.open("POST",url,true);
            xhr.setRequestHeader("Content-Type","text/xml; charset=utf-8");
            xhr.setRequestHeader("Accept","*/*");
            xhr.onreadystatechange=callBack;
            xhr.send(soap);
        }

        function callBack(){
            if(xhr.readyState==4){
                var a=xhr.responseXML;
                alert(xhr.responseXML.getElementsByTagName("uid")[0].text);
                alert(xhr.responseXML.getElementsByTagName("uname")[0].text);
            }
        }

        function init(){
            xhr=new ActiveXObject("MSXML2.XMLHTTP.3.0");
        }

        init();
    </script>
