三、 複雜物件類型的WebService

1、這次我們編寫複雜點的WebService方法，返回的資料是我們定義屬性帶getter、setter方法JavaBean，一維數組、二維數組等。

看代碼：

代碼import java.io.File;import java.io.FileOutputStream;import java.io.IOException;import java.util.Random;import data.User;/** * <b>function:</b>複雜類型資料的WebService：位元組數組、返回一維int數組、二維String數組及自訂JavaBean對象等 * @author hoojo * @createDate 2011-1-13 下午03:34:52 * @file ComplexTypeService.java * @package  * @project Axis2WebService * @blog http://blog.csdn.net/IBM_hoojo * @email hoojo_@126.com * @version 1.0 */public class ComplexTypeService {public String upload4Byte(byte[] b, int len) {String path = "";FileOutputStream fos = null;try {String dir = System.getProperty("user.dir");File file = new File(dir + "/" + new Random().nextInt(100) + ".jsp");fos = new FileOutputStream(file);fos.write(b, 0, len);path = file.getAbsolutePath();System.out.println("File path: " + file.getAbsolutePath());} catch (Exception e) {e.printStackTrace();} finally {try {fos.close();} catch (IOException e) {e.printStackTrace();}}return path;}public int[] getArray(int i) {int[] arr = new int[i];for (int j = 0; j < i; j++) {arr[j] = new Random().nextInt(1000);}return arr;}public String[][] getTwoArray() {return new String[][] { { "中國", "北京" }, { "日本", "東京" }, { "中國", "上海", "南京" } };}public User getUser() {User user = new User();user.setAddress("china");user.setEmail("jack@223.com");user.setName("jack");user.setId(22);return user;}}

上面的WebService服務分別是傳遞位元組完成資料上傳，返回一維int數組和二維字串數組，以及返回User JavaBean對象。

下面看看User Bean代碼：

代碼package data;import java.io.Serializable;/** * <b>function:</b>User Entity * @author hoojo * @createDate Dec 16, 2010 10:20:02 PM * @file User.java * @package com.hoo.entity * @project AxisWebService * @blog http://blog.csdn.net/IBM_hoojo * @email hoojo_@126.com * @version 1.0 */public class User implements Serializable {private static final long serialVersionUID = 677484458789332877L;private int id;private String name;private String email;private String address;//getter/setter@Overridepublic String toString() {return this.id + "#" + this.name + "#" + this.email + "#" + this.address;}}

值得注意的是這個User對象的package是data，如果是其它的package，你就需要在tomcat目錄下的webapps中的axis2的WEB-INF目錄下建立一個data目錄，和你的User對象的目錄保持一致。否則你的WebService將會出現ClassNotFontException異常。然後重啟你的tomcat，雖然axis2支援熱部署。

2、編寫調用上面WebService的用戶端代碼，代碼如下：

代碼package com.hoo.service;import java.io.File;import java.io.FileInputStream;import java.io.IOException;import javax.xml.namespace.QName;import org.apache.axis2.addressing.EndpointReference;import org.apache.axis2.client.Options;import org.apache.axis2.rpc.client.RPCServiceClient;import com.hoo.entity.User;/** * <b>function:</b>複雜類型資料WebService用戶端調用代碼 * @author hoojo * @createDate 2011-1-13 下午03:36:38 * @file ComplexTypeServiceClient.java * @package com.hoo.service * @project Axis2WebService * @blog http://blog.csdn.net/IBM_hoojo * @email hoojo_@126.com * @version 1.0 */public class ComplexTypeServiceClient {public static void main(String[] args) throws IOException {RPCServiceClient client = new RPCServiceClient();Options options = client.getOptions();String address = "http://localhost:8080/axis2/services/ComplexTypeService";EndpointReference epr = new EndpointReference(address);options.setTo(epr);QName qname = new QName("http://ws.apache.org/axis2", "upload4Byte");String path = System.getProperty("user.dir");File file = new File(path + "/WebRoot/index.jsp");FileInputStream fis = new FileInputStream(file);int len = (int) file.length();byte[] b = new byte[len];int read = fis.read(b);//System.out.println(read + "#" + len + "#" + new String(b));fis.close();Object[] result = client.invokeBlocking(qname, new Object[] { b, len }, new Class[] { String.class });System.out.println("upload:" + result[0]);qname = new QName("http://ws.apache.org/axis2", "getArray");result = client.invokeBlocking(qname, new Object[] { 3 }, new Class[] { int[].class });int[] arr = (int[]) result[0];for (Integer i : arr) {System.out.println("int[] :" + i);}qname = new QName("http://ws.apache.org/axis2", "getTwoArray");result = client.invokeBlocking(qname, new Object[] {}, new Class[] { String[][].class });String[][] arrStr = (String[][]) result[0];for (String[] s : arrStr) {for (String str : s) {System.out.println("String[][]: " + str);}}qname = new QName("http://ws.apache.org/axis2", "getUser");result = client.invokeBlocking(qname, new Object[] {}, new Class[] { User.class });User user = (User) result[0];System.out.println("User: " + user);}}

上面的代碼運行後的結果是：

upload:D:\tomcat-6.0.28\bin\28.jsp int[] :548 int[] :201 int[] :759 String[][]: 中國 String[][]: 北京 String[][]: 日本 String[][]: 東京 String[][]: 中國 String[][]: 上海 String[][]: 南京 User: 22#jack#jack@223.com#china
