五、CXF WebService整合Spring

首先，CXF和spring整合需要准备如下jar包文件：

这边我是用Spring的jar包是Spring官方提供的，并没有使用CXF中的Spring的jar文件。

添加这么多文件后，首先在web.xml中添加如下配置：

<!-- 加载Spring容器配置 -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 设置Spring容器加载配置文件路径 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext-server.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>

<servlet>
    <servlet-name>CXFService</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>CXFService</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

然后在src目录中，新建一个applicationContext-server.xml文件，文件内容如下：

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jaxws="http://cxf.apache.org/jaxws"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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"

注意上面的带下划线加粗部分，这个很重要的哦！不能写错或是遗漏了。

添加完这个文件后，还需要在这个文件中导入这么几个文件。文件内容如下：

<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"/>

下面开始写服务器端代码，首先定制服务器端的接口，代码如下：

package com.hoo.service;

import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
import com.hoo.entity.User;
import com.hoo.entity.Users;

/**
 * <b>function:</b>定制客户端请求WebService所需要的接口
 * @author hoojo
 * @createDate 2011-3-18 上午08:22:55
 * @file ComplexUserService.java
 * @package com.hoo.service
 * @project CXFWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
@WebService
@SOAPBinding(style = Style.RPC)
public interface IComplexUserService {

    public User getUserByName(@WebParam(name = "name") String name);

    public void setUser(User user);
}

下面编写WebService的实现类，服务器端实现代码如下：

package com.hoo.service;

import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
import com.hoo.entity.User;
import com.hoo.entity.Users;

/**
 * <b>function:</b> WebService传递复杂对象，如JavaBean、Array、List、Map等
 * @author hoojo
 * @createDate 2011-3-18 上午08:22:55
 * @file ComplexUserService.java
 * @package com.hoo.service
 * @project CXFWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
@WebService
@SOAPBinding(style = Style.RPC)
@SuppressWarnings("deprecation")
public class ComplexUserService implements IComplexUserService {

    public User getUserByName(@WebParam(name = "name") String name) {
        User user = new User();
        user.setId(new Date().getSeconds());
        user.setName(name);
        user.setAddress("china");
        user.setEmail(name + "@hoo.com");
        return user;
    }

    public void setUser(User user) {
        System.out.println("############Server setUser###########");
        System.out.println("setUser:" + user);
    }
}

注意的是和Spring集成，这里一定要完成接口实现，如果没有接口的话会有错误的。

下面要在applicationContext-server.xml文件中添加如下配置：

<bean id="userServiceBean" class="com.hoo.service.ComplexUserService"/>

<bean id="inMessageInterceptor" class="com.hoo.interceptor.MessageInterceptor">
    <constructor-arg  value="receive"/>
</bean>

<bean id="outLoggingInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>
<!-- 注意下面的address，这里的address的名称就是访问的WebService的name -->
<jaxws:server id="userService" serviceClass="com.hoo.service.IComplexUserService" address="/Users">
    <jaxws:serviceBean>
        <!-- 要暴露的 bean 的引用 -->
        <ref bean="userServiceBean"/>
    </jaxws:serviceBean>
    <jaxws:inInterceptors>
        <ref bean="inMessageInterceptor"/>
    </jaxws:inInterceptors>
    <jaxws:outInterceptors>
        <ref bean="outLoggingInterceptor"/>
    </jaxws:outInterceptors>
</jaxws:server>

下面启动tomcat服务器后，在WebBrowser中请求：

http://localhost:8080/CXFWebService/Users?wsdl

如果你能看到wsdl的xml文件的内容，就说明你成功了，注意的是上面地址的Users就是上面xml配置中的address的名称，是一一对应的。

下面编写客户端请求的代码，代码如下：

package com.hoo.client;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import com.hoo.entity.User;
import com.hoo.service.IComplexUserService;

/**
 * <b>function:</b>请求Spring整合CXF的WebService客户端
 * @author hoojo
 * @createDate 2011-3-28 下午03:20:35
 * @file SpringUsersWsClient.java
 * @package com.hoo.client
 * @project CXFWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
public class SpringUsersWsClient {

    public static void main(String[] args) {
        //调用WebService
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setServiceClass(IComplexUserService.class);
        factory.setAddress("http://localhost:8080/CXFWebService/Users");

        IComplexUserService service = (IComplexUserService) factory.create();

        System.out.println("#############Client getUserByName##############");
        User user = service.getUserByName("hoojo");
        System.out.println(user);

        user.setAddress("China-Guangzhou");
        service.setUser(user);
    }
}

运行后，可以在控制台中看到

log4j:WARN No appenders could be found for logger (org.apache.cxf.bus.spring.BusApplicationContext).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

信息: Creating Service {http://service.hoo.com/}IComplexUserServiceService from class com.hoo.service.IComplexUserService
#############Client getUserByName##############
27#hoojo#hoojo@hoo.com#china

Tomcat控制台
  

这个server端是通过Spring整合配置的，下面我们将Client端也通过Spring配置完成整合。

首先增加applicationContext-client.xml配置文件，文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jaxws="http://cxf.apache.org/jaxws"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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"

    <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:client id="userWsClient" serviceClass="com.hoo.service.IComplexUserService"
        address="http://localhost:8080/CXFWebService/Users"/>
</beans>

客户端请求代码如下：

package com.hoo.client;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.hoo.entity.User;
import com.hoo.service.IComplexUserService;

/**
 * <b>function:</b>请求Spring整合CXF的WebService客户端
 * @author hoojo
 * @createDate 2011-3-28 下午03:20:35
 * @file SpringUsersWsClient.java
 * @package com.hoo.client
 * @project CXFWebService
 * @blog http://blog.csdn.net/IBM_hoojo
 * @email hoojo_@126.com
 * @version 1.0
 */
public class SpringUsersWsClient {

    public static void main(String[] args) {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-client.xml");

        IComplexUserService service = ctx.getBean("userWsClient", IComplexUserService.class);

        System.out.println("#############Client getUserByName##############");
        User user = service.getUserByName("hoojo");
        System.out.println(user);

        user.setAddress("China-Guangzhou");
        service.setUser(user);
    }
}

运行后结果如下：

#############Client getUserByName##############
45#hoojo#hoojo@hoo.com#china
############Server setUser###########
setUser:45#hoojo#hoojo@hoo.com#China-Guangzhou
