最近一直使用XFire做WebServices方式使用，總結一些相關經驗，本文以具體例子進行XFire開發過程分析
1、首先定義一個Interface,具體包含簡單類型傳值、返回自定義對象、返回集合三個接口方法
import java.util.List;
import com.gresoft.commons.core.exception.BusinessException;
import com.gresoft.sanitation.model.dictionary.Hospital;
public interface WebServicesInterface {
public String savePutXml(int i,String typecode) throws BusinessException;
public Hospital getList(int p);
public List getAll();
}
2、實現上述接口，實現業務邏輯
public class HospitalService extends HibernateEntityDao<Hospital> implements
WebServicesInterface {
private HospitalManager hospitalManager;
public void setHospitalManager(HospitalManager hospitalManager) {
this.hospitalManager = hospitalManager;
}
public String savePutXml(int o, String typecode) throws BusinessException {
// TODO Auto-generated method stub
Hospital h = new Hospital(o, typecode);
super.save(h);
System.out.println("ccccc");
return "gggg";
}
public Hospital getList(int p) {
// TODO Auto-generated method stub
Hospital h = hospitalManager.get(p);
System.out.println("name:" + h.getHospitalName());
return hospitalManager.get(p);
}
@SuppressWarnings("unchecked")
public List getAll() {
List list = hospitalManager.getAll();
System.out.println("size:" + list.size());
return hospitalManager.getAll();
}
}
定義自定義對象Hospital
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;
/**
* @author wuxj:
* @version 創建時間：2007-10-15 上午11:31:39
*/
@Entity
@Table(name = "HOSPITAL", schema = "DB2ADMIN")
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
public class Hospital implements java.io.Serializable {
private int hospitalId;
private String hospitalName;
public Hospital() {
}
public Hospital(int hospitalId) {
this.hospitalId = hospitalId;
}
public Hospital(int hospitalId, String hospitalName) {
this.hospitalId = hospitalId;
this.hospitalName = hospitalName;
}
@Id
@Column(name = "HOSPITAL_ID", unique = true, nullable = false)
public int getHospitalId() {
return hospitalId;
}
public void setHospitalId(int hospitalId) {
this.hospitalId = hospitalId;
}
@Column(name = "HOSPITAL_NAME", nullable = false, length = 20)
public String getHospitalName() {
return hospitalName;
}
public void setHospitalName(String hospitalName) {
this.hospitalName = hospitalName;
}
}
3、編寫XFire的描述文件
描述文件為WebServicesInterface.aegis.xml，一定要與Interface接口類在同一個目錄，否則會出錯誤
只需要描述返回是集合的描述，getAll方法返回是List集合，需要對集合中的元素進行定義，在這里是Hospital對象
<?xml version="1.0" encoding="UTF-8"?>
<mappings>
<mapping>
<method name="getAll">
<return-type
componentType="com.gresoft.sanitation.model.dictionary.Hospital" />
</method>
<property name="hibernateGenericDao" ignore="true" />
<!-- 在HospitalService中這個文件可以不用，主要是為了定義返回為對象或集合 -->
<!--
<method name="savePutXml">
<parameter index="1" componentType="java.lang.String" />
</method>
-->
</mapping>
</mappings>
4、編寫xfire-servlet.xml文件
xfire是跟spring結合一起使用的，所以用到了spring相關內容。
注意：位置一定要在WEB-INF目錄下
key="/echo"中的echo為你在客戶端訪問的地址,具體看client內容
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- START SNIPPET: xfire -->
<bean
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="urlMap">
<map>
<entry key="/echo" value-ref="echo" />
</map>
</property>
</bean>
<!-- Declare a parent bean with all properties common to both services -->
<bean id="echo"
class="org.codehaus.xfire.spring.remoting.XFireExporter">
<property name="serviceFactory" ref="xfire.serviceFactory" />
<property name="xfire" ref="xfire" />
<property name="serviceBean" ref="hospitalService" />
<property name="serviceInterface"
value="com.gresoft.sanitation.service.WebServicesInterface" />
</bean>
<!-- END SNIPPET: xfire -->
</beans>
5、編寫客戶端測試
import java.net.MalformedURLException;
import org.codehaus.xfire.XFireFactory;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
public class HospitalServiceClient {
public static void main(String args[]) {
Service srvcModel = new ObjectServiceFactory()
.create(WebServicesInterface.class);
XFireProxyFactory factory = new XFireProxyFactory(XFireFactory
.newInstance().getXFire());
// XFireProxyFactory factory = new XFireProxyFactory(getXFire());
String helloWorldURL = "http://localhost:8080/sanitation/service/echo";
// String helloWorldURL ="xfire.local://echo";
try {
WebServicesInterface srvc = (WebServicesInterface) factory.create(
srvcModel, helloWorldURL);
Hospital h = new Hospital();
h.setHospitalId(11);
h.setHospitalName("測試");
// System.out.print(srvc.sayHello("wuxj")+"\n");
// RegisterApply apply = new RegisterApply();
// apply.setOperateDate("20071221");
// apply.setRegisterId("1000");
// srvc.savePutXml(apply);
System.out.println(srvc.savePutXml(11, "測試"));
srvc.getList(1);
srvc.getAll();
// System.out.print(((MsdpUser)srvc.getUser().get(0)).getUid());
} catch (MalformedURLException e) {
System.out.println("wrong");
e.printStackTrace();
}
}
}
6、定義web.xml的xfire
紅色字體一定要加上，而且是固定格式，這是xfire需要加載的文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring/*.xml,
classpath:org/codehaus/xfire/spring/xfire.xml</param-value>
</context-param>
<!--Spring ApplicationContext 載入 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- XFire WebServices的入口 -->
<servlet>
<servlet-name>xfire</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>xfire</servlet-name>
<url-pattern>/service/*</url-pattern>
</servlet-mapping>
</web-app>
