契约式开发webservice实践之spring-ws+Xmlbeans

契约式开发webservice实践之spring-ws+Xmlbeans
1、开发环境
JDK1.4.2.*
Tomcat6.0.*
Spring-2.5.5
Spring-ws-1.5.4
XmlBeans-2.3

2、确定需要请求和应答的xml实例
Request.xml

<?xml version="1.0" encoding="UTF-8"?>
<wl_request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://footmarktech.com/samples">
<flights>
<flight><segment>PEK-CAN<segment><ticketNo>7841234656</ticketNo></flight>
<flight><segment>PEK-CAN<segment><ticketNo>7841234656</ticketNo></flight>
</flights>
</wl_request>

Response.xml

<?xml version="1.0" encoding="UTF-8"?>
<wl_response xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://footmarktech.com/samples">
<flights>
<flight><segment>PEK-CAN<segment><ticketNo>7841234656</ticketNo></flight>
<flight><segment>PEK-CAN<segment><ticketNo>7841234656</ticketNo></flight>
</flights>
</wl_response>

3、设置XmlBeans环境
设置XMLBEANS_HOME
并将 %XMLBEANS_HOME%/bin增加到path路径中

4、使用xmlbeans tool准备数据契约xsd
根据上一步骤请求和应答的实例xml执行如下命令
inst2xsd -enumerations never Request.xml Response.xml
将生成的schema0.xsd文件命名为 Airline.xsd

将 Airline.xsd放在 ${web-context}/WEB-INF目录下
5、使用xmlbeans tool生成OXM数据映射对象
需要说明的是这些对象是跟Xmlbeans耦合比较紧的,不是POJO
执行如下命令
scomp -out Airline.jar Airline.xsd

6、准备运行时和编译时jar包

Spring-ws1.5.4必须使用springframework2.5版本以上
其对org.springframework.core.io.Resource版本要求较高
必须加入spring-webmvc-2.5.5.jar
org.springframework.web.servlet.FrameworkServlet从2.5版本后被分到spring-webmvc.jar包,并不包含于主spring包内

注,可能有些jar包没有用到
7、书写web.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name>Web</display-name>

<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>ws-spring-ws</servlet-name>
        <servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class>
   </servlet>

<servlet-mapping>
        <servlet-name>ws-spring-ws</servlet-name>
        <url-pattern>/spring-ws/*</url-pattern>
    </servlet-mapping>

</web-app>

8、书写业务实现

package demo1;

public class Order {
private String id;

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}
}

package demo1;

public interface OrderService {
Order getOrder(String id);
}

package demo1;

public class OrderServiceImpl implements OrderService{
public Order getOrder(String id) {
  Order order = new Order();
  order.setId(id);
  return order;
}

}

书写spring配置放在classpath下
applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC
"-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">

9、书写Spring-ws EndPoint

package demo1;

import org.springframework.oxm.Marshaller;
import org.springframework.ws.server.endpoint.AbstractMarshallingPayloadEndpoint;

import com.footmarktech.samples.WlRequestDocument;
import com.footmarktech.samples.WlResponseDocument;

public class SampleMarshallingEndpoint extends
AbstractMarshallingPayloadEndpoint {

private final OrderService orderService;

public SampleMarshallingEndpoint(OrderService orderService,
   Marshaller marshaller) {
  super(marshaller);
  this.orderService = orderService;
}

protected Object invokeInternal(Object request) throws Exception {
  com.footmarktech.samples.WlRequestDocument ab = null;
  ab = (WlRequestDocument)request;

  //TODO invoke orderService

  WlResponseDocument rs = (WlResponseDocument) WlResponseDocument.Factory.newInstance();
  rs.addNewWlResponse().addNewFlights().addNewFlight().setTicketNo(ab.getWlRequest().getFlights().getFlightArray(0).getTicketNo());
  return rs;
}
}

10、书写ws-spring-ws-servlet.xml
放置于${web-context}/WEB-INF目录下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 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-2.0.xsd">

</beans>

11、开发客户端

配置applicationContext1.xml放置于 classpath demo1.client包内

</beans>

package demo1.client;

import java.io.File;
import java.io.IOException;

import javax.xml.transform.Source;

import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlObject;
import org.jdom.JDOMException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.Resource;
import org.springframework.ws.client.core.WebServiceTemplate;
import org.springframework.ws.client.core.support.WebServiceGatewaySupport;
import org.springframework.xml.transform.ResourceSource;
import org.springframework.xml.transform.StringResult;

import com.footmarktech.smscenter.webservice.SendSMDocument;
import com.footmarktech.smscenter.webservice.SendSMResponseDocument;
import com.footmarktech.samples.WlRequestDocument;
import com.footmarktech.samples.WlResponseDocument;

public class EchoClient {
public static void RequestSpring() {
  ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext1.xml", EchoClient.class);
  WebServiceTemplate webServiceTemplate = (WebServiceTemplate) applicationContext
    .getBean("webServiceTemplate1");
  WlRequestDocument request = WlRequestDocument.Factory.newInstance();
  request.addNewWlRequest().addNewFlights().addNewFlight().setTicketNo(new Long(1231235555).longValue());

  WlResponseDocument response = (WlResponseDocument)webServiceTemplate.marshalSendAndReceive(request);
  System.out.println(response.getWlResponse().getFlights().getFlightArray(0).getTicketNo());
}

public static void main(String[] args) throws IOException, JDOMException {
RequestSpring();

}
