对于webservice,之前只是有一点学习,算是一知半解吧。今天项目中需要做这么个功能,对外提供接口,我装作很懂webservice一样,说没问题,小事儿。其实心里是想等周末的时候自己查查资料,学习一下,因为这东西以前弄过,的确不难。谁知周末有事耽搁了,周一来了就要交差的。查了一会儿资料,突然想起项目中也许已经有了相关的例子呢,因为项目的平台早已搭建完了的。果然不出所料,于是就简单很多了。下面先将例子贴出来,然后讲解过程中遇到的小问题。
一个简单的例子分为三步(基本环境、webservice类开发、配置文件)
基本环境: 首先spring3.0的环境要搭好,cxf相关的jar引入进来。
webservice类开发(接口和实现类):
package com.cxf.server;
import java.util.Date;
import java.util.List;
import javax.jws.WebService;
import com.vo.WorkUnitVO;
@WebService
public interface IWorkUnitInfo {
public List<WorkUnitVO> getWorkUnitByDate(Date date);
}
package com.cxf.server;
import java.util.Date;
import java.util.List;
import javax.jws.WebService;
import org.springframework.beans.factory.annotation.Autowired;
import com.service.IWorkUnitService;
import com..vo.WorkUnitVO;
@WebService(endpointInterface = "com.cslc.crius.common.ws.cxf.server.IWorkUnitInfo")
public class WorkUnitInfoImpl implements IWorkUnitInfo {
@Autowired
private IWorkUnitService workUnitService;//项目中其他的类,获取结果集用到。
@Override
public List<WorkUnitVO> getWorkUnitByDate(Date date) {
return workUnitService.getWorkUnitByDate(date);
}
public IWorkUnitService getWorkUnitService() {
return workUnitService;
}
public void setWorkUnitService(IWorkUnitService workUnitService) {
this.workUnitService = workUnitService;
}
}
配置文件1:(web.xml配置文件 加入cxf相关配置文件)
<!-- CXF Web Services 配置信息 -->
<servlet>
<display-name>CXF Servlet</display-name>
<servlet-name>CXFServlet</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/services/*</url-pattern><!--注意这里的配置/services/ 这里是生成wsdl路径的一部分,wsdl的路径:http://ip:8080/项目路径/services/spring cxf配置文件中的address?wsdl-->
</servlet-mapping>
配置文件2:(spring cxf 配置文件)<?xml version="1.0" encoding="UTF-8"?>
<!-- START SNIPPET: beans -->
<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://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.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:endpoint
id="helloWorld"
implementor="com.cslc.crius.common.ws.cxf.server.HelloWorldImpl"
address="/HelloWorld" />
<jaxws:endpoint
id="workUnitInfo"
implementor="#workUnitInfoImpl"
address="/WorkUnitInfo"
/>
<bean id="workUnitInfoImpl" class="com.cslc.crius.common.ws.cxf.server.WorkUnitInfoImpl">
<!--如果webservice中有需要加载其他类,采用注解的方式不行,需要在配置文件中显示声明-->
<property name="workUnitService" ref="workUnitServiceImpl"></property>
</bean>
</beans>
<!-- END SNIPPET: beans -->
以上几步完成以后既可以进行相关的测试了,发布到tomcat服务器中,启动服务器。第一步,测试wsdl:
访问 http://ip:8080/项目路径/services/spring cxf配置文件中的address?wsdl,例如:http://129.0.0.0:8080/abc/services/WorkUnitInfo?wsdl
第二步:测试webservice
1、WebService 客户端 spring 配置文件 wsclient-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- START SNIPPET: beans -->
<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://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schema/jaxws.xsd">
<bean id="workUnitInfoClient" class="com.cslc.crius.common.ws.cxf.server.IWorkUnitInfo"
factory-bean="workUnitInfoFactory" factory-method="create">
</bean>
<bean id="workUnitInfoFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="com.cslc.crius.common.ws.cxf.server.IWorkUnitInfo"/>
<property name="address" value="http://localhost:8080/viminal/services/WorkUnitInfo?wsdl"></property>
</bean>
</beans>
<!-- END SNIPPET: beans -->
2、调用WebService接口的测试程序
package com.cxf.client;
import java.util.Date;
import java.util.List;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.cslc.crius.common.utils.DateUtils;
import com.cslc.crius.common.ws.cxf.server.IWorkUnitInfo;
import com.cslc.crius.viminal.vo.WorkUnitVO;
public final class Client {
private Client() {
}
public static void main(String args[]) throws Exception {
// START SNIPPET: client
ClassPathXmlApplicationContext context
= new ClassPathXmlApplicationContext(new String[] {"client/wsclient-context.xml"});
IWorkUnitInfo work = (IWorkUnitInfo)context.getBean("workUnitInfoClient");
Date date = DateUtils.parseDate("2012-10-01");
List<WorkUnitVO> r = work.getWorkUnitByDate(date);
for (int i=0;i<r.size();i++) {
System.out.println(r.get(i).getWorkUnitTitle());
}
System.exit(0);
// END SNIPPET: client
}
}
基本步骤就是上面这些,对外提供的接口就是上面测试wsdl所用的url。<pre>
