MyEclipse中和許多網(wǎng)站的WebService教程以HelloWord為例,內(nèi)容比較簡(jiǎn)單,在實(shí)際的項(xiàng)目應(yīng)用中大多都是對(duì)象和集合,現(xiàn)在我們擴(kuò)展下,使用webservice傳遞對(duì)象,字符串,集合;
下面是我們?cè)O(shè)計(jì)的webservice的接口:
1
package com.test.service;
2
3import java.util.List;
4
5
public interface IPerson {
6
//根據(jù)用戶名獲取密碼
7 public String getPassword(String name);
8 //根據(jù)用戶名獲取Person對(duì)象
9 public Person getPersonByName();
10 //獲取全部成員
11 public List<Person> getAllPerson();
12
}
其中有三個(gè)方法包含了傳遞:String,Object,List集合;
2,這里我們實(shí)現(xiàn)接口中定義的業(yè)務(wù)邏輯
package com.test.service;
import java.util.LinkedList;
import java.util.List;
public class PersonImpl implements IPerson {
public String getPassword(String name) {
return "Password";
}
public Person getPersonByName() {
return new Person("ObjectName","ObjectPass");
}
public java.util.List<Person> getAllPerson(){
List list = new LinkedList();
list.add(new Person("One","PassOne"));
list.add(new Person("Two","PassTwo"));
list.add(new Person("Three","PassThree"));
return list;
}
}
在實(shí)際應(yīng)用中比較復(fù)雜,可能用調(diào)用持久層的Dao,返回需要的結(jié)果,這里我們直接創(chuàng)建一個(gè)模擬數(shù)據(jù),下面是實(shí)現(xiàn)類中用到的對(duì)象
1package com.test.service;
2
3public class Person {
4 private String name;
5 private String password;
6
7 public Person() {
8 super();
9 }
10 public Person(String name, String password){
11 super();
12 this.name = name;
13 this.password = password;
14 }
15 public String getPassword(){
16 return password;
17 }
18 public void setPassword(String password){
19 this.password = password;
20 }
21}

3,編寫(xiě)XFire要求的WebSevice定義描述文件，如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>
<name>Person</name>
<serviceClass>com.test.service.IPerson</serviceClass>
<implementationClass>
com.test.service.PersonImpl
</implementationClass>
<style>wrapped</style>
<use>literal</use>
<scope>application</scope>
</service></beans>
本文件的放置位置很關(guān)鍵,此文件放在src/META-INF/xfire/services.xml，如果使用MyEclipse新建的不是webapplication,而是webservice項(xiàng)目,這一步就省去自己編寫(xiě)了,編譯時(shí)會(huì)自動(dòng)編譯到classes的相應(yīng)目錄下面。web.z
5,編譯xml,定義XfireConfigableServlet
1<?xml version="1.0" encoding="UTF-8"?>
2<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">
3 <servlet>
4 <servlet-name>XFireServlet</servlet-name>
5 <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
6 <load-on-startup>0</load-on-startup>
7 </servlet>
8 <servlet-mapping>
9 <servlet-name>XFireServlet</servlet-name>
10 <url-pattern>/services/*</url-pattern>
11 </servlet-mapping>
12 <welcome-file-list>
13 <welcome-file>index.jsp</welcome-file>
14 </welcome-file-list>
15</web-app>

所有的工作都已經(jīng)作完，接下來(lái)在部署在tomcate下，啟動(dòng)服務(wù)器，在地址欄鍵入：
http://127.0.0.1:8080/MyWebService/srevice/Person?wsdl
如果出現(xiàn)xml描述文件就成功了；
