Question

xfire与spring整合为什么会报serviceinterface is required

Answer 1

本文只是介绍XFire+Spring使用注解的集成，版本为Xfire 1.2.6+Spring 3.0.5，测试环境为Tomcat6.0。

1.首先建一个Web工程，引入相应的jar包，这一步不再多说。

2.修改web.xml，加入以下代码：

[html] view plaincopyprint?
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
<servlet-name>xfireServlet</servlet-name>
<servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>xfireServlet</servlet-name>
<url-pattern>/service/*</url-pattern>
</servlet-mapping>
[html] view plaincopyprint?
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
<servlet-name>xfireServlet</servlet-name>
<servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>xfireServlet</servlet-name>
<url-pattern>/service/*</url-pattern>
</servlet-mapping>
3.在classpath下加入Spring配置文件applicationContext.xml，加入以下代码：
[html] view plaincopyprint?
<context:component-scan base-package="my.webservice" />

<!-- XFire start -->
<import resource="classpath:org/codehaus/xfire/spring/xfire.xml" />
<bean id="webAnnotations" class="org.codehaus.xfire.annotations.jsr181.Jsr181WebAnnotations" />
<bean id="jsr181HandlerMapping" class="org.codehaus.xfire.spring.remoting.Jsr181HandlerMapping">
<property name="xfire" ref="xfire" />
<property name="webAnnotations" ref="webAnnotations" />
</bean>
<!-- XFire end -->
[html] view plaincopyprint?
<context:component-scan base-package="my.webservice" />

<!-- XFire start -->
<import resource="classpath:org/codehaus/xfire/spring/xfire.xml" />
<bean id="webAnnotations" class="org.codehaus.xfire.annotations.jsr181.Jsr181WebAnnotations" />
<bean id="jsr181HandlerMapping" class="org.codehaus.xfire.spring.remoting.Jsr181HandlerMapping">
<property name="xfire" ref="xfire" />
<property name="webAnnotations" ref="webAnnotations" />
</bean>
<!-- XFire end -->
4.定义WebService接口，添加相应注解：
[java] view plaincopyprint?
@WebService
public interface IBookService {

@WebMethod
public Book getBook();
}
[java] view plaincopyprint?
@WebService
public interface IBookService {

@WebMethod
public Book getBook();
}
5.接口实现类，注解中serviceName定义发布的服务名，endpointInterface定义实现的接口：
[java] view plaincopyprint?
@Component
@WebService(serviceName="BookService",
endpointInterface = "my.webservice.IBookService")
public class BookServiceImpl implements IBookService {

@Override
public Book getBook() {

Book b = new Book(1, "Java核心思想", 100);

System.out.println(">>>>>>Server: " + b);

return b;
}
}
[java] view plaincopyprint?
@Component
@WebService(serviceName="BookService",
endpointInterface = "my.webservice.IBookService")
public class BookServiceImpl implements IBookService {

@Override
public Book getBook() {

Book b = new Book(1, "Java核心思想", 100);

System.out.println(">>>>>>Server: " + b);

return b;
}
}
6.以上便是服务端的配置及实现，是不是很简单。把工程发布到Tomcat并启动，在浏览器中输入：http://127.0.0.1:8080/XFireTest/service/BookService?wsdl（BookService为上面serviceName定义的名称），如果浏览器中显示BookService相关xml信息，则表示WebService发布成功。

7.客户端调用服务端方法：

[java] view plaincopyprint?
@Test
public void testBookService() {
Service serviceModel = new ObjectServiceFactory().create(IBookService.class);
String url = "http://127.0.0.1:8080/XFireTest/service/BookService";
IBookService service = null;

try {
service = (IBookService) new XFireProxyFactory().create(serviceModel, url);
Book b = service.getBook();
System.out.println(">>>>>>>>Client: " + b);
} catch (Exception e) {
e.printStackTrace();
}
}

下面来讲客户端调用。===================

1. 加入跟server端一样的library。参考上面的第1点

2. 将serviceClass对应的接口加入客户端中。

3. 书写调用代码： PS:代码太简单，不另外注释了。

private String url = "http://10.4.1.16:8080/eccn/services/exCommService";
public String checkLicenseByOB(String obno) throws Exception{
Service serviceModel = new ObjectServiceFactory().create(IExCommService.class);
IExCommService service = (IExCommService)
new XFireProxyFactory().create(serviceModel, url);

return service.checkLicenseByOB(obno);
}

在生成接口对应的service后，用户就可以像调用本地方法一样调用远程的方法了。
