当多个WebService的时候,我们要管理它的Session。这个时候我们得依靠ServiceGroupContext保存session信息;然后在发布WebService的时候,services.xml文件的的service表情的scope就不再说request或是transportsession了,而是application;最后同样要开启对session的管理,即options.setManageSession(true);
1、 首先多个WebService的session管理的代码如下:
代码package com.hoo.service;
import org.apache.axis2.context.MessageContext;
import org.apache.axis2.context.ServiceGroupContext;
/**
* function:管理多个会话Session信息
* @author hoojo
* @createDate 2011-3-9 下午05:11:07
* @file LoginSessionService.java
* @package com.hoo.service
* @project Axis2WebService
* @blog http://blog.csdn.net/IBM_hoojo
* @email hoojo_@126.com
* @version 1.0
*/
public class LoginSessionService {
public boolean login(String userName, String password) {
MessageContext context = MessageContext.getCurrentMessageContext();
ServiceGroupContext ctx = context.getServiceGroupContext();
if ("admin".equals(userName) && "123456".equals(password)) {
ctx.setProperty("userName", userName);
ctx.setProperty("password", password);
ctx.setProperty("msg", "登陆成功");
return true;
}
ctx.setProperty("msg", "登陆失败");
return false;
}
public String getLoginMessage() {
MessageContext context = MessageContext.getCurrentMessageContext();
ServiceGroupContext ctx = context.getServiceGroupContext();
return ctx.getProperty("userName") + "#" + ctx.getProperty("msg");
}
}
和上面的Session一样的操作,只不过是用ServiceGroupContext上下文来存取session信息
另外还需要用一个Service来查询session的信息,SearchService的代码如下:
代码package com.hoo.service;
import org.apache.axis2.context.MessageContext;
import org.apache.axis2.context.ServiceGroupContext;
/**
* function:查找多服务Session会话中的消息
* @author hoojo
* @createDate 2011-3-9 下午05:22:39
* @file SearchSessionServcie.java
* @package com.hoo.service
* @project Axis2WebService
* @blog http://blog.csdn.net/IBM_hoojo
* @email hoojo_@126.com
* @version 1.0
*/
public class SearchSessionServcie {
public String findSessionMessage(String key) {
MessageContext mc = MessageContext.getCurrentMessageContext();
ServiceGroupContext ctx = mc.getServiceGroupContext();
if (ctx.getProperty(key) != null) {
return "找到的数据<" + key + ", " + ctx.getProperty(key) + ">";
} else {
return "没有找到<" + key + ">的数据";
}
}
}
2、 编写services.xml来发布这2个服务,还以前不一样的。这一次是用一个services.xml文件配置2个service,同时发布2个服务。Xml代码如下:
代码<serviceGroup>
<service name="LoginSessionService" scope="application">
<description>
Web Service Session例子
description>
<parameter name="ServiceClass">
com.hoo.service.LoginSessionService
parameter>
<messageReceivers>
<messageReceiver mep=""
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
<messageReceiver mep=""
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
messageReceivers>
service>
<service name="SearchSessionService" scope="application">

<messageReceiver mep=""
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
messageReceivers>
service>
serviceGroup>
3、 发布完成后,可以通过查看发布的WebService服务,编写客户端的测试代码,code如下:
代码package com.hoo.service;
import javax.xml.namespace.QName;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
/**
* function:多会话Session管理,WebService客户端请求代码
* @author hoojo
* @createDate 2011-3-9 下午05:17:15
* @file LoginSessionServiceClient.java
* @package com.hoo.service
* @project Axis2WebService
* @blog http://blog.csdn.net/IBM_hoojo
* @email hoojo_@126.com
* @version 1.0
*/
public class LoginSessionServiceClient {
public static void main(String[] args) throws AxisFault {
String target = "";
RPCServiceClient client = new RPCServiceClient();
Options options = client.getOptions();
options.setManageSession(true);
EndpointReference epr = new EndpointReference(target);
options.setTo(epr);
QName qname = new QName("", "login");
//指定调用的方法和传递参数数据,及设置返回值的类型
Object[] result = client.invokeBlocking(qname, new Object[] { "admin", "123456" }, new Class[] { boolean.class });
System.out.println(result[0]);
qname = new QName("", "getLoginMessage");
result = client.invokeBlocking(qname, new Object[] { null }, new Class[] { String.class });
System.out.println(result[0]);
target = "";
epr = new EndpointReference(target);
options.setTo(epr);
qname = new QName("", "findSessionMessage");
result = client.invokeBlocking(qname, new Object[] { "userName" }, new Class[] { String.class });
System.out.println(result[0]);
qname = new QName("", "findSessionMessage");
result = client.invokeBlocking(qname, new Object[] { "msg" }, new Class[] { String.class });
System.out.println(result[0]);
qname = new QName("", "findSessionMessage");
result = client.invokeBlocking(qname, new Object[] { "password" }, new Class[] { String.class });
System.out.println(result[0]);
}
}
运行后结果如下:
true
admin#登陆成功
找到的数据
找到的数据
找到的数据
4、 如果将services.xml文件"SearchSessionService" scope="application">的内容改成scope=transportsession,看看什么情况。是不是找不到session中的内容。
