<DIV id=cnblogs_post_body>
1、这次我们编写复杂点的WebService方法，返回的数据是我们定义属性带getter、setter方法JavaBean，一维数组、二维数组等。
看代码：
<DIV class=cnblogs_code><IMG id=Code_Closed_Image_973618 .click="this.style.display='none'; document.getElementById('Code_Closed_Text_973618').style.display='none'; document.getElementById('Code_Open_Image_973618').style.display='inline'; document.getElementById('Code_Open_Text_973618').style.display='inline';" height=16 src="http://www.cnblogs.com/Images/OutliningIndicators/ContractedBlock.gif" width=11 align=top><IMG id=Code_Open_Image_973618 style="DISPLAY: none" .click="this.style.display='none'; document.getElementById('Code_Open_Text_973618').style.display='none'; getElementById('Code_Closed_Image_973618').style.display='inline'; getElementById('Code_Closed_Text_973618').style.display='inline';" height=16 src="http://www.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif" width=11 align=top>代码import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Random;
import data.User;

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;
for (int j = 0; j < i; j++) {
arr = 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;
}
}</DIV> 

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：
<DIV class=cnblogs_code><IMG id=Code_Closed_Image_465653 .click="this.style.display='none'; document.getElementById('Code_Closed_Text_465653').style.display='none'; document.getElementById('Code_Open_Image_465653').style.display='inline'; document.getElementById('Code_Open_Text_465653').style.display='inline';" height=16 src="http://www.cnblogs.com/Images/OutliningIndicators/ContractedBlock.gif" width=11 align=top><IMG id=Code_Open_Image_465653 style="DISPLAY: none" .click="this.style.display='none'; document.getElementById('Code_Open_Text_465653').style.display='none'; getElementById('Code_Closed_Image_465653').style.display='inline'; getElementById('Code_Closed_Text_465653').style.display='inline';" height=16 src="http://www.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif" width=11 align=top>代码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;
}
}</DIV> 

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：
<DIV class=cnblogs_code><IMG id=Code_Closed_Image_161176 .click="this.style.display='none'; document.getElementById('Code_Closed_Text_161176').style.display='none'; document.getElementById('Code_Open_Image_161176').style.display='inline'; document.getElementById('Code_Open_Text_161176').style.display='inline';" height=16 src="http://www.cnblogs.com/Images/OutliningIndicators/ContractedBlock.gif" width=11 align=top><IMG id=Code_Open_Image_161176 style="DISPLAY: none" .click="this.style.display='none'; document.getElementById('Code_Open_Text_161176').style.display='none'; getElementById('Code_Closed_Image_161176').style.display='inline'; getElementById('Code_Closed_Text_161176').style.display='inline';" height=16 src="http://www.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif" width=11 align=top>代码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;

/**

* @author hoojo
* @createDate 2011-1-13 下午03:36:38
* @file ComplexTypeServiceClient.java
* @package com.hoo.service
* @project Axis2WebService

*/
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;
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);

qname = new QName("http://ws.apache.org/axis2", "getArray");
result = client.invokeBlocking(qname, new Object[] { 3 }, new Class[] { int[].class });
int[] arr = (int[]) result;
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;
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;
System.out.println("User: " + user);
}
}</DIV> 

上面的代码运行后的结果是：
<TABLE cellSpacing=0 cellPadding=0 border=1>
<TBODY>
<TR>
<TD vAlign=top width=568>
upload:D:\tomcat-6.0.28\bin\28.jsp

String[][]: 南京
