mule：轻量级的ESB消息框架，可以和spring集成，支持seda架构。
seda：分段式事件驱动架构，可以在每个stage上施加不同的thread，来确保程序的最大吞吐量。
几个名词解释
Connectiors：支持不同协议的连接器，屏蔽有不同协议带来的复杂度
EndPoints Address：终端地址，类似于jms等消息机制
UMO：统一消息对象，在mule里面他们是一些POJO，负责解释消息，处理消息，然后再发送给下一个UMO，形成一个UMO处理链。

下载下来并解压缩打开examples文件夹，里面有很多例子，最初级的例子是echo
D:/mule/mule-standalone-2.2.1/examples
1.运行echo项目，初次体验mule
执行echo.bat批处理文件，有三种选择，你可以在命令窗口下输入1，2或者3选择不同的模式1是基本模式，2是Axis模式，3是CXF模式
对应着D:/mule/mule-standalone-2.2.1/examples/echo/conf文件夹下的三个配置文件，根据你的选择加装不同的配置文件
2.自己动手写一个echo程序，代码如下
EchoService接口
package com.zxgllhh.testMule;
public interface EchoService {
??? public String echo(String echo);
}
EchoComponent实现类
package com.zxgllhh.testMule.impl;
import com.zxgllhh.testMule.EchoService;
public class EchoComponent implements EchoService {
??? public String echo(String echo) {
??? ??? System.out.println("Echo Component start....");
??? ??? return echo;
??? }
}
加装配置文件的主动类
package com.zxgllhh.run;
import org.mule.api.MuleContext;
import org.mule.api.context.MuleContextFactory;
import org.mule.config.spring.SpringXmlConfigurationBuilder;
import org.mule.context.DefaultMuleContextFactory;
public class EagleMuleMain {
??? public static void main(String[] args) throws Exception{
??? ??? try {
??? ??? ??? String configFile = "com/zxgllhh/run/mule-config.xml";
??? ??? ??? String[] configFileArr = new String[] { configFile };
??? ??? ??? MuleContextFactory muleContextFactory = new DefaultMuleContextFactory();
??? ??? ??? MuleContext context = muleContextFactory
??? ??? ??? ??? ??? .createMuleContext(new SpringXmlConfigurationBuilder(
??? ??? ??? ??? ??? ??? ??? configFileArr));
??? ??? ??? context.start();
??? ??? } catch (Exception t) {
??? ??? ??? t.printStackTrace();
??? ??? }
??? }
}

发布成webservice应用，有webservice驱动程序运行代码修改如下
接口
package com.zxgllhh.testMule;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
@WebService
public interface EchoService {
??? //定义返回参数节点
??? @WebResult(name="responseResultByzxg")
??? //定义请求参数节点
??? public String echo(@WebParam(name="requestResultByzxg") String string);
}
实现类
package com.zxgllhh.testMule.impl;
import com.zxgllhh.testMule.EchoService;
public class EchoComponent implements EchoService {
??? public String echo(String echo) {
??? ??? return "Hello,"+echo;
??? }
}
