三、 复杂对象类型的WebService

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Random;
import data.User;

/**
* function:复杂类型数据的WebService：字节数组、返回一维int数组、二维String数组及自定义JavaBean对象等
* @author hoojo

* @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[][] { { "中国", "北京" }, { "日本", "东京" }, { "中国", "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服务分别是传递字节完成数据上传，返回一维int数组和二维字符串数组，以及返回User JavaBean对象。

下面看看User Bean代码：

[code]package data;

import java.io.Serializable;

/**
* function: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

@Override
public String toString() {
return this.id + "#" + this.name + "#" + this.email + "#" + this.address;
}
}

值得注意的是这个User对象的package是data，如果是其它的package，你就需要在tomcat目录下的webapps中的axis2的WEB-INF目录下

创建一个data目录，和你的User对象的目录保持一致。否则你的WebService将会出现ClassNotFontException异常。然后重启你的tomcat，

虽然axis2支持热部署。

2、编写调用上面WebService的客户端代码，代码如下：

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;

/**
* function:复杂类型数据WebService客户端调用代码
* @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);
}
}

[code]上面的代码运行后的结果是： 
upload:D:/tomcat-6.0.28/bin/28.jsp

int[] :548

int[] :201

int[] :759

String[][]: 中国

String[][]: 北京

String[][]: 日本

String[][]: 东京

String[][]: 中国

String[][]: 上海

String[][]: 南京
