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:
代码 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 * @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:
代码 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 @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:
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; /** * <b>function:</b>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); } }
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 User: 22#jack#jack@223.com#china |
