创建webservice 用service.xml配置(复杂点的方法)

用Axis2实现Web Service，虽然可以将POJO类放在axis2/WEB-INF/pojo目录中直接发布成Web Service，这样做不需要进行任何配置，但这些POJO类不能在任何包中。这似乎有些不方便，为此，Axis2也允许将带包的POJO类发布成Web Service。

看网上的一些例子都比较简单,就是些打印之类的方法.看了些例子动手建了一个,下面把步骤贴上:

另附源码：http://download.csdn.net/detail/liweifengwf/5762875

一、新建一个web程序 webservice01

二、把官网的 axis2.war 中的 conf、modules、services、和lib中的jar包考到WEB-INF中

在services中新建文件夹 META-INF 中新建 service.xml

这个文件中写 关于服务类的配置

结构如下图：

services中的文件夹要和服务类相同，不知道为什么，这点理解的不够，肯定还有其他的方法。

三、修改web.xml文件，添加以下内容

 <!--Axis2 config start-->
	<servlet>
	    <servlet-name>AxisServlet</servlet-name>
	    <servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>
	    <load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
	 <servlet-name>AxisServlet</servlet-name>
	 <url-pattern>/services/*</url-pattern>
	</servlet-mapping>
  <!--Axis2  end-->

四、实体类 User

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 [e-mail]
 * @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

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public String getAddress() {
		return address;
	}

	public void setAddress(String address) {
		this.address = address;
	}

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

五、建服务类：

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

/**
 * <b>function:</b>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
 */
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("[e-mail]");
		user.setName("jack");
		user.setId(22);
		return user;
	}
}

六、service.xml文件配置

<?xml version="1.0" encoding="UTF-8"?>
<service name="ComplexTypeService">
    <description>
        ComlxexTypeService Service Example
    </description>
    <parameter name="ServiceClass">
       com.cn.ComplexTypeService
    </parameter>  

    <operation name="upload4Byte">
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
    </operation>
     <operation name="getArray">
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
    </operation>
     <operation name="getTwoArray">
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
    </operation>
     <operation name="getUser">
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
    </operation>  

</service>

其实operation元素不用每个方法都去配置的，也可以加上一个通用的

<!-- 也可以全部通用一个配置 -->
      <messageReceivers>
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
            class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
            class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
    </messageReceivers> 

七、客户端

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 data.User;

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

八、重启tomcat 访问http://localhost:8080/axis2/services/ComplexTypeService?wsdl，看到wsdl页面说明配置成功。

运行客户端得到如下：
