资源描述

Mule学习笔记作者：郑先全 msn: 1. 原理请参照《Using JBI for Service-Oriented Integration (SOI)》 2. Mule简介 2.1. 架构 2.2. 核心概念请参照《Architecture Guid》 2.3. repository 如果想保持新鲜，访问她们CVS是最佳办法。 cvs -d :pserver::/scm/mule login (no password) cvs -d :pserver::/scm/mule co mule 注意：从4月14日开始，不再使用cvs，而采用svn，途径如下： 2.4. IDE 有自己IDE: Download: Eclipse update site: 3. Mule使用 3.1. Mule安装我JDK为1.4.2_05。下载后，解压缩，并设立MULE_HOME为解压缩目录测试：提供echo例子程序是个比较好测试工具，放在%MULE_HOME%\samples\echo下，cmd并切换到改目录bin下，执行mule-echo.bat，即可看到如下窗口：恭喜，阐明安装成功。 Tip: 事实上，在我环境中会提示一种关于缺少一种sax文献错误，郁闷，通过到sax王张并下载sax2r3.zip后，把里面xml-apis.jar解压缩到%MULE_HOME%\lib下，可以解决该问题。 3.2. echo例子分析参照这个地址（+Example）简介，应当会有一种比较好开始。 3.2.1. 过程图示描述为： 1、通过两种方式接入（红色标记）：一为System.in，另一为Soap(http)方式； 2、每种接入都可以通过接入器(Connector)通过NMR路由转发后，进行输出，当前通过两种方式输出：一为System.out，另一为Soap(http)方式可以通过Mule提供工具生成配备图，如下： 3.2.2. 有关代码（The Echo Service） The echo Service is a POJO that implements an EchoService interface - public interface EchoService { public String echo(String echo); } The implementation (i.e the POJO to be managed by Mule) looks like - package ponents.simple; public class EchoComponent extends LogComponent implements EchoService { public String echo(String echo) { return echo; } } 3.2.3. 配备和阐明 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mule-configuration PUBLIC "-//SymphonySoft //DTD mule-configuration XML V1.0//EN" "  <mule-configuration id="Mule_Echo_Sample" version="1.0">  <description>描述</description>  <connector name="SystemStreamConnector" className="org.mule.providers.stream.SystemStreamConnector"> <properties> <property name="promptMessage" value="Please enter something："/> <property name="messageDelayTime" value="1000"/> </properties> </connector>  <model name="echoSample"> <mule-descriptor name="EchoUMO" implementation="ponents.simple.EchoComponent"> <!—接入点设立，当前为stream和axis两种类型--> <inbound-router> <endpoint address="stream://System.in"/> <endpoint address="axis:http://localhost:8081/services"/> </inbound-router> <!—输出点设立，当前为stream类型--> <outbound-router> <router className="org.mule.routing.outbound.OutboundPassThroughRouter"> <endpoint address="stream://System.out"/> </router> </outbound-router> </mule-descriptor> </model> </mule-configuration> 3.3. Webapp例子分析这个例子其实是对原有几种例子在webapp集成，通过使用MuleClient进行基于编码调用。 Tips: 1、可以通过干预web.xml，逐个加载需要揣摩例子，便于分析； 2、开始时，使用默认加载方式。 3.3.1. echo例子略 3.3.2. Hello例子 3.3.2.1. 简介本例子重要用于演示两个transformer、两个UMO之间信息转换和事件交互。 Transformer： StringToNameString Transformer： NameStringToChatString GreeterUMO ChitChatUMO 3.3.2.2. 代码分析几种java文献，阐明如下： POJO/javabean: NameString.java ChatString.java SERVICE: Greeter.java ChitChatter.java Transformer: HttpRequestToString.java NameStringToChatString.java StringToNameString.java ChatStringToString.java 3.3.2.3. 配备 Web.xml <param-value>/WEB-INF/mule-config.xml, /WEB-INF/mule-echo-config.xml, /WEB-INF/mule-hello-config.xml </param-value> Mule-hello-config.xml  <mule-descriptor name="GreeterUMO"

</outbound-router> </mule-descriptor> <mule-descriptor name="ChitChatUMO" implementation="org.mule.samples.hello.ChitChatter"> <inbound-router> <endpoint address="vm://chitchatter" transformers="NameStringToChatString"/> </inbound-router> </mule-descriptor> Tips: 1、 endpoint address并没有实际意义，但由于在整个Mule实例里面必要唯一，故可以理解为命名空间 2、 Transformer必要继承AbstractTransformer，重要实现doTransform接口办法 3.3.3. loanbroker 3.3.3.1. 简介异步实现：同步实现： 3.3.3.2. 配备图请参照：+Broker+Example 3.3.3.3. 类图 3.3.3.4. 配备文献详细分析 <mule-configuration id="Loan_broker_Sync" version="1.0"> <!—定义EndPointà <endpoint-identifiers>
