WebService开发笔记 1 -- 利用cxf开发WebService竟然如此简单

    现在的项目中需要用到SOA概念的地方越来越多,最近我接手的一个项目中就提出了这样的业务要求,需要在.net开发的客户端系统中访问java开发的web系统,这样的业务需求自然需要通过WebService进行信息数据的操作。下面就将我们在开发中摸索的一点经验教训总结以下，以供大家参考.

在WebService开发笔记 2 -- VS 2005 访问WebServcie更简单中作一个跨平台访问WebServcie服务的例子....

在WebService开发笔记 3 -- 增强访问 WebService 的安全性通过一个简单的用户口令验证机制来加强一下WebService的安全性....

我们项目的整个架构使用的比较流行的WSH MVC组合,即webwork2 + Spring + Hibernate;
1.首先集成Apacha CXF WebService 到 Spring 框架中;
   apache cxf 下载地址:http://people.apache.org/dist/incubator/cxf/2.0.4-incubator/apache-cxf-2.0.4-incubator.zip
  在spring context配置文件中引入以下cxf配置 
	<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" />

   在web.xml中添加过滤器: 
	<servlet>
		<servlet-name>CXFServlet</servlet-name>
		<servlet-class>
			org.apache.cxf.transport.servlet.CXFServlet
		</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>CXFServlet</servlet-name>
		<url-pattern>/services/*</url-pattern>
	</servlet-mapping>


2.开发服务端WebService接口: 
/**
 * WebService接口定义类.
 * 
 * 使用@WebService将接口中的所有方法输出为Web Service.
 * 可用annotation对设置方法、参数和返回值在WSDL中的定义.
 */
@WebService
public interface WebServiceSample {


	/**
	 * 一个简单的方法,返回一个字符串
	 * @param hello
	 * @return
	 */
	String say(String hello);
	
	/**
	 * 稍微复杂一些的方法,传递一个对象给服务端处理
	 * @param user
	 * @return
	 */
	String sayUserName(
			@WebParam(name = "user") 
			UserDTO user);
	
	/**
	 * 最复杂的方法,返回一个List封装的对象集合
	 * @return
	 */
	public 
	@WebResult(partName="o")
	ListObject findUsers();

}

由简单到复杂定义了三个接口,模拟业务需求;

3.实现接口 
/**
 * WebService实现类.
 * 
 * 使用@WebService指向Interface定义类即可.
 */
@WebService(endpointInterface = "cn.org.coral.biz.examples.webservice.WebServiceSample")
public class WebServiceSampleImpl implements WebServiceSample {

	public String sayUserName(UserDTO user) {
		return "hello "+user.getName();
	}

	public String say(String hello) {
		return "hello "+hello;
	}

	public ListObject findUsers() {
		ArrayList<Object> list = new ArrayList<Object>();
		
		list.add(instancUser(1,"lib"));
		list.add(instancUser(2,"mld"));
		list.add(instancUser(3,"lq"));
		list.add(instancUser(4,"gj"));
		ListObject o = new ListObject();
		o.setList(list);
		return o;
	}
	
	private UserDTO instancUser(Integer id,String name){
		UserDTO user = new UserDTO();
		user.setId(id);
		user.setName(name);
		return user;
	}
}


4.依赖的两个类:用户对象与List对象 
/**
 * Web Service传输User信息的DTO.
 * 
 * 分离entity类与web service接口间的耦合，隔绝entity类的修改对接口的影响.
 * 使用JAXB 2.0的annotation标注JAVA-XML映射，尽量使用默认约定.
 * 
 */
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "User")
public class UserDTO {

	protected Integer id;

	protected String name;

	public Integer getId() {
		return id;
	}

	public void setId(Integer value) {
		id = value;
	}

	public String getName() {
		return name;
	}

	public void setName(String value) {
		name = value;
	}
}

关于List对象,参照了有关JWS的一个问题中的描述:DK6.0 自带的WebService中 WebMethod的参数好像不能是ArrayList 或者其他List
传递List需要将List 包装在其他对象内部才行 (个人理解 如有不对请指出) ,我在实践中也遇到了此类问题.通过以下封装的对象即可以传递List对象. 
/**
 * <p>Java class for listObject complex type.
 * 
 * <p>The following schema fragment specifies the expected content contained within this class.
 * 
 * <pre>
 * <complexType name="listObject">
 *   <complexContent>
 *     <restriction base="{http://www.w3.org/2001/XMLSchema}anyType">
 *       <sequence>
 *         <element name="list" type="{http://www.w3.org/2001/XMLSchema}anyType" maxOccurs="unbounded" minOccurs="0"/>
 *       </sequence>
 *     </restriction>
 *   </complexContent>
 * </complexType>
 * </pre>
 * 
 * 
 */
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "listObject", propOrder = { "list" })
public class ListObject {

	@XmlElement(nillable = true)
	protected List<Object> list;

	/**
	 * Gets the value of the list property.
	 * 
	 * <p>
	 * This accessor method returns a reference to the live list,
	 * not a snapshot. Therefore any modification you make to the
	 * returned list will be present inside the JAXB object.
	 * This is why there is not a <CODE>set</CODE> method for the list property.
	 * 
	 * <p>
	 * For example, to add a new item, do as follows:
	 * <pre>
	 *    getList().add(newItem);
	 * </pre>
	 * 
	 * 
	 * <p>
	 * Objects of the following type(s) are allowed in the list
	 * {@link Object }
	 * 
	 * 
	 */
	public List<Object> getList() {
		if (list == null) {
			list = new ArrayList<Object>();
		}
		return this.list;
	}

	public void setList(ArrayList<Object> list) {
		this.list = list;
	}

}


5.WebService 服务端 spring 配置文件 ws-context.xml 
<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://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd"
	default-autowire="byName" default-lazy-init="true">
	
	<jaxws:endpoint id="webServiceSample"
		address="/WebServiceSample" implementor="cn.org.coral.biz.examples.webservice.WebServiceSampleImpl"/>

</beans>


WebService 客户端 spring 配置文件 wsclient-context.xml 
<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://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd"
	default-autowire="byName" default-lazy-init="true">

	<!-- ws client -->
	<bean id="identityValidateServiceClient" class="cn.org.coral.admin.service.IdentityValidateService"
		factory-bean="identityValidateServiceClientFactory" factory-method="create" />

	<bean id="identityValidateServiceClientFactory"
		class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
		<property name="serviceClass"
			value="cn.org.coral.admin.service.IdentityValidateService" />
		<property name="address"
			value="http://88.148.29.54:8080/coral/services/IdentityValidateService"/>
	</bean>
	
</beans>

6.发布到tomcat服务器以后通过以下地址即可查看自定义的webservice接口生成的wsdl:
http://88.148.29.54:8080/aio/services/WebServiceSample?wsdl

7.调用WebService接口的Junit单元测试程序 
package test.coral.sample;

import org.springframework.test.AbstractDependencyInjectionSpringContextTests;

import cn.org.coral.biz.examples.webservice.WebServiceSample;
import cn.org.coral.biz.examples.webservice.dto.UserDTO;

public class TestWebServiceSample extends
		AbstractDependencyInjectionSpringContextTests {
	WebServiceSample webServiceSampleClient;

	public void setWebServiceSampleClient(WebServiceSample webServiceSampleClient) {
		this.webServiceSampleClient = webServiceSampleClient;
	}
	
	@Override
	protected String[] getConfigLocations() {
		setAutowireMode(AUTOWIRE_BY_NAME);
                  //spring 客户端配置文件保存位置
		return new String[] { "classpath:/cn/org/coral/biz/examples/webservice/wsclient-context.xml" };
	}
	
	public void testWSClinet(){
		Assert.hasText(webServiceSampleClient.say(" world"));
	}
}

如果实现一个返回List类型的接口，可以获得list的大小，但是list里的对象都为空；如果用楼主的listobject来封装，在执行listobject.getList()方法时，取得的为空
不知道这个应该怎么解决，谢谢！

或者是将bus配置到JaxWsClientFactory中去

	xmlns:jaxws="http://cxf.apache.org/jaxws"

	</bean>
	
</beans>




多谢楼上回复，按照你的配置，问题已经解决。但是你这段配置有一个错误
<property name="bus" value="#cxf" />
这一行应该配置在 identityValidateServiceClientFactory 这个 bean 中，如果配置在 identityValidateServiceClient 这个 bean ，会报找不到 property 的错误。
另外，应该写成 <property name="bus" ref="cxf">
按照你的写法会出现 classcast 错误：不能把 String 转成 Bus 对象。


我修改了你的配置，如下： 

<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://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans.xsd"
	default-autowire="byName" default-lazy-init="true">
     <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-extension-http.xml"/> 
	<!-- ws client -->
	<bean id="identityValidateServiceClient" class="cn.org.coral.admin.service.IdentityValidateService"
		factory-bean="identityValidateServiceClientFactory" factory-method="create">
        </bean> 

	<bean id="identityValidateServiceClientFactory"
		class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
		<property name="serviceClass"
			value="cn.org.coral.admin.service.IdentityValidateService" />
		<property name="address"
			value="http://88.148.29.54:8080/coral/services/IdentityValidateService"/>
                <property name="bus" ref="cxf" />
	</bean>
	
</beans>
19 楼 jnn 2008-04-22  
alexma 写道
NPE 的错误似乎是由于 bus 没有被注入。但是按照楼主的帖子，并不需要注入这个才对。另外，我把 war 部署到 Jboss 4.2，启动服务器的时候，有这样的错误：
09:36:08,607 ERROR [STDERR] 2008-4-22 9:36:08 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
。。。。
09:36:09,588 ERROR [STDERR] 2008-4-22 9:36:09 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
。。。。
09:36:10,079 ERROR [STDERR] 2008-4-22 9:36:10 org.apache.cxf.endpoint.ServerImpl initDestination
信息: Setting the server's publish address to be /MoscoService

这些信息不是错误信息，这是因为CXF使用的是j.u.l 而不是Jboss使用的log4j。这样CXF的日志输出就被定向到了错误输出流里面了。 你看到这些日志应该是 INFO level的。
对于NPE，的确是楼主在配置client factory的过程中没有制定bus 而造成的。
如果不想指定bus你可以使用 来定义客户端。 
<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:jaxws="http://cxf.apache.org/jaxws"

<jaxws:client id="wsdlLocation" 
    serviceClass="org.apache.hello_world_soap_http.Greeter"
    serviceName="s:SOAPService"

    xmlns:s="http://apache.org/hello_world_soap_http"
    address="http://localhost:8080/simpleWithAddress"
    wsdlLocation="wsdl/hello_world.wsdl"/>


或者是将bus配置到JaxWsClientFactory中去

我想问下,这个要在http里怎么请求,在网上找了个HELLOWORLD的例子,但是只能在java运行,没有http请求路径(http://localhost:8080/cxf/ws/helloWorld?wsdl后面如何把参数传进去)


不明白你的问题是什么，你是问在调用的client的时候如何将wsdl 的url 传给client吗？
17 楼 alexma 2008-04-22  
NPE 的错误似乎是由于 bus 没有被注入。但是按照楼主的帖子，并不需要注入这个才对。另外，我把 war 部署到 Jboss 4.2，启动服务器的时候，有这样的错误：

09:36:08,607 ERROR [STDERR] 2008-4-22 9:36:08 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass

15 楼 alexma 2008-04-21  
我用的就是 cxf2.0.5 + spring2.5.2 ，还是有NPE
14 楼 alexma 2008-04-18  
我也考虑换 xfire 了，不知道 xfire 对 jax-ws 的系列标准支持的怎么样。
13 楼 peihexian 2008-04-17  
如果只是要开发web serivices的话用xfire就够了吧？cxf 50M的运行库吓死人。
12 楼 alexma 2008-04-17  
我也遇到了同样的问题。
p.s.我用的是 spring 2.5.2 + cxf 2.0.5 bundle

报上面错误啊，按照楼主的做的代码，Help me


有没有用annotation标注JAVA-XML映射呀?

 * 使用JAXB 2.0的annotation标注JAVA-XML映射，尽量使用默认约定.

public class UserDTO {   
  
    protected Integer id;

10 楼 java_code 2008-03-24  
我想问下,我最近看了别人的开发环境和开发录象,就是那个STP 环境下创建SOAP TOOL来做例子,遇到下面一些问题:
   每一个接口生成一个WSDL文件,发布的时候有多少接口发布多少个项目,显然是错误了,应该怎么处理.
   还有就是一般我们都是写好接口,用接口来生成WSDL ,那生成的WSDL 是怎么关联上我们的实现类,因为实现类都是我们自己的逻辑.就是在实现类的上面 + 类似这个句解吗:@WebService(endpointInterface = "com.gdcn.bpaf.service.ISysCatalogService")?

如果谁有自己写的测试项目的完整代码请给一份 非常感谢:mycart@126.com

如果一定要用Spring 2.5.2 你也可以下载CXF2.0.5 snapshot[1] 试验一下。 我记得这个bug应该是修正了的。
[1] http://people.apache.org/repo/m2-snapshot-repository/org/apache/cxf/apache-cxf/2.0.5-incubator-SNAPSHOT/apache-cxf-2.0.5-incubator-20080319.024727-10.zip

用2.0.5是通过的,但是jira上面写的是2.0.4就fixed

Spring 2.5.2 是在2008年2月底发布的，而CXF 2.0.4 是在2008年1月底发布的。 JIRA上说2.0.4 fixed 的bug 应该是与Spring 2.5相关的bug。
