Flash 與后臺(tái)交互方式包括了：

1. LoadVars(xml) 實(shí)際上就是flash里面一個(gè)對(duì)象，類似一個(gè)連接器。新建之后，通過(guò)sendAndLoad獲取、設(shè)置值。和httpposter一樣
var data_lv = new LoadVars();

2. flash remoting. flash需要安裝components；后臺(tái)服務(wù)器需要OpenAMF。
gateway_conn = NetServices.createGatewayConnection(); myService = gateway_conn.getService("myservice", this);

3. webservice 也是在flash里面初始化一個(gè)ws的對(duì)象，然后調(diào)用。var ws:WebService = new WebService(ws_url);

4. XMLSocket 主要是即時(shí)通訊 var socket:XMLSocket = new XMLSocket();

5. 直接開flash的socket

http://androider.javaeye.com/blog/268933
在一個(gè)AMF交互的例子中，服務(wù)器建立一個(gè)MAP對(duì)象，例如：

HashMap map=new HashMap();

map.put("Event", "人物移動(dòng)");

map.put("user", "閃刀浪子");

map.put("x", 100);

map.put("y", 100);

這樣flash就可以獲取這個(gè)對(duì)象：var obj:Object=new Object();

Spring 技術(shù)小結(jié)

1. Spring IoC容器的意義

使用BeanFactory，根據(jù)制定的xml，動(dòng)態(tài)生成對(duì)象然后加載。

只要是從BeanFactory獲取的對(duì)象，都會(huì)根據(jù)xml進(jìn)行裝配。

2. Spring MVC

在web.xml配置了DispatcherServlet，讓所有請(qǐng)求都被這個(gè)servlet攔截。同時(shí)配置了這個(gè)servlet的初始化對(duì)象。
。init-param = /WEB-INF/Config.xml ->
。viewResolver：：org.springframework.web.servlet.view.InternalResourceViewResolver
。urlMapping：：org.springframework.web.servlet.handler.SimpleUrlHandlerMapping

這個(gè)urlMapping的目標(biāo)，可能是被spring接管的對(duì)象，例如SimpleFormController

當(dāng)配置了DispactcherServlet之后，通過(guò)設(shè)置合適的初始化對(duì)象，能夠?qū)崿F(xiàn)某種MVC模式。

3. spring + blazeds 集成
http://static.springsource.org/spring-flex/docs/1.0.x/reference/html/ch02s02.html

在web.xml配置了2個(gè)dispatcherservlet
。*.service === /WEB-INF/remoting-servlet.xml
。/messagebroker/* === /WEB-INF/flex-config.xml 表示把blazeds的請(qǐng)求映射到messagebroker

。第一個(gè)servlet繼續(xù)配置了urlMapping
==HessianServiceExporter可將一個(gè)普通bean導(dǎo)出成遠(yuǎn)程服務(wù) 這樣這些被映射出來(lái)的service可以通過(guò)url訪問。
問題：這些service有固定的方法，比如execute，那么這些方法如何被調(diào)用了？代碼上看，是被command調(diào)用了。
回答：見第二個(gè)配置

。第二個(gè)servlet同樣配置了urlMapping；還包括
..MessageBrokerHandlerAdapter
..RemotingDestinationExporter -> callDisptacherService -> CallDispatcher -> Command.execute
問題：那么CallDispatcher的Call是如何調(diào)用的？
回答：在Flash的xml文件里面指定調(diào)用了。

這樣故事就全部被串起來(lái)了。

首先blazeds是個(gè)servlet，被封裝過(guò)后，能夠解析flash傳輸?shù)腶mf格式。

通過(guò)spring的配置，flash的請(qǐng)求被轉(zhuǎn)移到了messagebroker = blazeds，同時(shí)這個(gè)messagebroker依賴了特定的bean，例如callHandler. 這些handler又依賴了service 的屬性，這個(gè)屬性就是我可以控制的，同時(shí)被flash調(diào)用的。

例如

what is web.xml :: listener
它能捕捉到服務(wù)器的啟動(dòng)和停止! 在啟動(dòng)和停止觸發(fā)里面的方法做相應(yīng)的操作!
一定是httpServlet
http://zhidao.baidu.com/question/39980900

如何加載services-config.xml

MessageBrokerFactoryBean將會(huì)去尋找BlazeDS的配置文件(默認(rèn)位置為/WEB-INF/flex/services-config.xml)

Oops! Spring Quick Start

本文講解一個(gè)不規(guī)范的spring quick start.

1. 下載spring的插件包，什么版本之類的不用管了。反正能用。
spring.jar http://www.boxcn.net/shared/yg306zac1h
common-logging.jar http://www.boxcn.net/shared/ix93ziqljv

2. 進(jìn)入eclipse，F(xiàn)ile - New - Java Project.
projectname = spring001 ===> Next
在新建導(dǎo)向的第二頁(yè)，是Java Settings, 選擇Libraries -> Add External JARS -> 添加上面2個(gè)jar
finish

3. 進(jìn)入Package Explorer, 在src下新建一個(gè)class.
Package = com.java114.spring.test
Name = HelloWordSpring
再?gòu)?fù)選框：public static void main(String[] args) 鉤上

4. 在HelloWordSpring.java 輸入以下的代碼

package com.java114.spring.test;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;

public class HelloWordSpring
{
    private String msg;

    public void setMsg(String msg)
    {
        this.msg = msg;
    }

    public void sayHello()
    {
        System.out.println(msg);
    }

    public static void main(String[] args)
    {
        Resource res = new ClassPathResource("com/java114/spring/test/bean.xml");
        BeanFactory factory = new XmlBeanFactory(res);
        HelloWordSpring hello = (HelloWordSpring) factory.getBean("helloBean");
        hello.sayHello();
    }

}

5. 在和HelloWordSpring.java 相同目錄下面，再新建一個(gè)xml文件，名字是bean.xml, 內(nèi)容如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
<bean id="helloBean" class="com.java114.spring.test.HelloWordSpring">
<property name="msg" value="simple spring demo"/>
</bean>
</beans>

為什么這樣寫，我也不知道，不管他。

6. 鼠標(biāo)右鍵選擇HelloWordSpring.java, 選擇Run As - Java Applications，得到結(jié)果：

2010-6-16 21:39:47 org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions
信息: Loading XML bean definitions from class path resource [com/java114/spring/test/bean.xml]
simple spring demo

Oops! Axis quick start ! part 3 -- stub

比較難的一部分

前提條件：
axis安裝路徑 C:\ericsson\javaextend\axis-1_4
項(xiàng)目名稱：axisdemo
已經(jīng)有的類：com.service.myService.java
配置文件：server-config.wsdd

1. 在項(xiàng)目添加java2wsdl目錄

2.目錄下面添加build.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project name="Generate WSDL from JavaBeans as Web Services" default="j2w-all" basedir=".">
    <property name="build.dir" value="../build/classes" />
    <property name="axis.dir" location="C:\ericsson\javaextend\axis-1_4" />
    <path id="classpath.id">
        <fileset dir="${axis.dir}/lib">
            <include name="*.jar" />
        </fileset>
        <pathelement location="${build.dir}" />
    </path>
    <taskdef name="axis-java2wsdl" classname="org.apache.axis.tools.ant.wsdl.Java2WsdlAntTask" loaderref="axis">
        <classpath refid="classpath.id" />
    </taskdef>
    <target name="j2w-all">
        <antcall target="j2w-JavaBeanWS" />
    </target>
    <target name="j2w-JavaBeanWS">
        <axis-java2wsdl classname="com.service.myService" classpath="${build.dir}" methods="getusername" output="myService.wsdl" location="http://localhost:8080/axisdemo/services/myService" namespace="http://localhost:8080/axisdemo/services/myService" namespaceImpl="http://localhost:8080/axisdemo/services/myService">
        </axis-java2wsdl>
    </target>
</project>

注意：build.dir / axis.dir / j2w-javabeanws幾個(gè)地方的內(nèi)容要修改。

3. 右鍵點(diǎn)擊build.xml，運(yùn)行ant，就可以看到生成了myService.wsdl

4.現(xiàn)在要把這個(gè)wsdl轉(zhuǎn)化成為java，新建目錄：wsdl2java

5. 新建一個(gè)build.xml，內(nèi)容：

<?xml version="1.0" encoding="UTF-8"?>
<project name="wsclient" default="all" basedir=".">
    <property name="axis.home" location="C:\ericsson\javaextend\axis-1_4" />
    <property name="options.output" location="../wsdl2java" />
    <path id="axis.classpath">
        <fileset dir="${axis.home}/lib">
            <include name="**/*.jar" />
        </fileset>
    </path>
    <taskdef resource="axis-tasks.properties" classpathref="axis.classpath" />
    <target name="-WSDL2Axis" depends="init">
        <mkdir dir="${options.output}" />
        <axis-wsdl2java output="${options.output}" url="${options.WSDL-URI}" verbose="true" />
    </target>
    <target name="init">
        <echo>Warning: please update the associated WSDL file(s) in the folder wsdl before running the target!</echo>
        <echo>Warning: Just run the target(s) related with your developing work!</echo>
        <echo>
        </echo>
    </target>
    <target name="all">
        <antcall target="myService" />
    </target>
    <target name="myService">
        <antcall target="-WSDL2Axis">
            <param name="options.WSDL-URI" location="../java2wsdl/myService.wsdl" />
        </antcall>
    </target>
</project>

注意修改的地方：axis.home

6.build ant，在wsdl2java目錄下面多出來(lái)了4個(gè)類：
myService.java
MyServiceService.java
myServiceServiceLocator.java
MyServiceSoapBindingStub.java
全部拷貝到src目錄下面

7.在src目錄下面添加類：

package com.axistest;

import localhost.axisdemo.services.myService.MyService;
import localhost.axisdemo.services.myService.MyServiceServiceLocator;

public class myServiceTestorByStubs
{
    public static void main(String[] args) throws Exception
    {
        MyServiceServiceLocator Service = new MyServiceServiceLocator();
        MyService port = Service.getmyService();
        String response   port.getusername(鄒萍");
        System.out.println(response);
    }
}

8.最后運(yùn)行java application就完成了

Oops! Axis quick start ! part 2 -- wsdd

reference:
part1

1. in package explorer, change myService.java:

package com.service;
public class myService {
public String getusername(String name){
return "Hello "+name+",this is an Axis Web Service";
}
}

and ctrl+1 to solve the package problem( or you can create dir and move file yourself)

2.in WebContent/WEB-INF/, create server-config.wsdd

3. in src/, create myServiceTestorByWSDD.java

import java.net.MalformedURLException;
import java.rmi.RemoteException;
import javax.xml.rpc.ServiceException;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
public class myServiceTestorByWSDD {
public tatic void main(String[] args) throws ServiceException,MalformedURLException, RemoteException {
        String endpoint = http://localhost:8080/oopsaxis1/services/myService;
        Service service = new Service();                // 創(chuàng)建一個(gè)Service實(shí)例，注意是必須的！
        Call call = (Call) service.createCall();   // 創(chuàng)建Call實(shí)例，也是必須的！
        call.setTargetEndpointAddress(new java.net.URL(endpoint));// 為Call設(shè)置服務(wù)的位置
        call.setOperationName("getusername");              // 注意方法名與JavaBeanWS.java中一樣！！
        String res = (String) call.invoke(new Object[] { "pixysoft" });       // 返回String，傳入?yún)?shù)
        System.out.println(res);
}
}

4. open tomcat, and :http://localhost:8080/oopsaxis1/servlet/AxisServlet,you can see:

And now

Some Services
myService (wsdl)
getusername

5. right click myServiceTestorByWSDD.java, run as java application.

done!

Oops! Axis quick start ! part 1 -- simple demo

reference:

http://www.cnblogs.com/cy163/archive/2008/11/28/1343516.html

pre-condition:
1.install eclipse
2.install tomcat plugin

process:
1.download axis lib: http://ws.apache.org/axis

2. set classpath:
1．AXIS_HOME
D:\Java\axis-1_4（這是我的Axis路徑）
2．AXIS_LIB
%AXIS_HOME%\lib
3．AXIS_CLASSPATH
%AXIS_LIB%\axis.jar;%AXIS_LIB%\commons-discovery-0.2.jar;%AXIS_LIB%\commons-logging-1.0.4.jar;%AXIS_LIB%\jaxrpc.jar;%AXIS_LIB%\saaj.jar;%AXIS_LIB%\log4j-1.2.8.jar;%AXIS_LIB%\xml-apis.jar;%AXIS_LIB%\xercesImpl.jar;%AXIS_LIB%\wsdl4j-1.5.1.jar;%AXIS_LIB%\activation.jar;%AXIS_LIB%\xmlrpc-2.0.jar
4．CLASSPATH
.;%JAVA_HOME%\lib\tools.jar;%JAVA_HOME%\lib\dt.jar; %AXIS_CLASSPATH%;
5．在你的%TOMCAT_HOME%\common\lib下需要加入三個(gè)包 activation.jar、mail.jar、tools.jar，注意這三個(gè)包是必須的，盡管tools.jar很常見，但這也是運(yùn)行Axis所必須的包。

3.FIle - new - dynamic web project
projectname: oopsaxis1
target runtime: apache tomcat V5.5

4. oopsaxis1/WebContent/WEB-INF/lib,add lib from %AXIS_HOME%\lib
axis.jar/axis-ant.jar/commons-log.jar...

5.oopsaxis1/WebContent/WEB-INF/web.xml, replace by %AXIS_HOME%\webapps\axis\WEB-INF\web.xml

6.oopsaxis1/src, add java file:

public class myService
{
    public String getusername(String name)
    {
        return "Hello " + name + ",this is an Axis DII Web Service";
    }
}

7.copy myService to oopsaxis1/WebContent, and rename to myService.jws

8. right click myService.jws, run as - run on server, you can see:
http://localhost:8080/oopsaxis1/myService.jws

There is a Web Service here
Click to see the WSDL

click the link, you can see the wsdl

9. in eclipse - package explorer - src, new class:

package com.oopsaxis;

import java.net.MalformedURLException;
import java.rmi.RemoteException;

import javax.xml.rpc.ParameterMode;
import javax.xml.rpc.ServiceException;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;

public class myServiceTestorByjws
{
    public static void main(String[] args) throws ServiceException,
            MalformedURLException, RemoteException
    {
        String endpoint = http://localhost:8080/oopsaxis1/myService.jws;
        String name = " pixysoft";
        Service service = new Service();
        Call call = (Call) service.createCall();

        call.setTargetEndpointAddress(new java.net.URL(endpoint));
        call.addParameter("param1", XMLType.XSD_STRING, ParameterMode.IN);
        call.setOperationName("getusername");
        call.setReturnType(XMLType.XSD_STRING);
        String ret = (String) call.invoke(new Object[] { name });
        System.out.println("返回結(jié)果：" + ret);
    }
}

10. right click myServiceTestorByjws, run as java application,you get:
返回結(jié)果：Hello pixysoft,this is an Axis DII Web Service

done!
