MULE2.1.2系列学习(一)

最近很闲只好学点知识，我们公司又用到soa，不过也是很少的部分，不过这块看来是趋势，就像EJB一样，只要有一些大商在哪顶着，什么技术都可以流行，在中国更是这样，领导一拍脑袋，方案就定下料。废话少说，来点实际的。

?

?

第一步：我们要去官方去下载2.1.2版本，不过现在的最新版本好像是2.2了，不过今天我的例子是2.1.2的，说真的mule在版本控制方面真够差劲，2.02的竟然跑不通1.3的例子，兼容性不好，（扯远了）下载地址http://www.mulesoft.org/display/MULE/Download

下载下来解压缩到D:/Downloads/java

第二步配置环境变量MULE_HOME=D:/Downloads/java/mule-2.1.2

???????????????????????????path = %MULE_HOME%/bin

?

第三步：就是写程序了

在eclipse里面新建一个工程mule，加入%MULE_HOME%/lib 下的opt和mule下的jar包 网上很多都是这样加的，不过在2.1.2环境下启动会报异常。因为这里少了endorsed下的jar

?第一个就是简单的接口类MuleService.java

??? package com.eagle.mule.test;

??? import javax.jws.WebParam;
??? import javax.jws.WebService;

??? @WebService
??? public interface MuleService {
?
??????? public String testMule(@WebParam(name="str")String str);
??? }

第二个就是实现类MuleServiceImpl.java

??? package com.eagle.mule.test.impl;

??? import javax.jws.WebService;

??? import com.eagle.mule.test.MuleService;

??? @WebService(serviceName="eagleMuleService",
??? endpointInterface="com.eagle.mule.test.MuleService")
??? public class MuleServiceImp implements MuleService {

???????? public String testMule(String str) {
?????????? ? System.out.println("----service---");
??????????? ?return "hello--"+str;
?????? ?}
?? }

第三步启动服务器：

import org.mule.api.MuleContext;
import org.mule.api.MuleException;
import org.mule.api.config.ConfigurationException;
import org.mule.api.context.MuleContextFactory;
import org.mule.api.lifecycle.InitialisationException;
import org.mule.config.spring.SpringXmlConfigurationBuilder;
import org.mule.context.DefaultMuleContextFactory;

public class EagleMuleMain {
?public static void main(String[] args) throws ConfigurationException,InitialisationException {
??try {
???String configFile = "mule_config.xml";
???String[] configFileArr = new String[] { configFile };
???MuleContextFactory muleContextFactory = new DefaultMuleContextFactory();
???MuleContext context = muleContextFactory
?????.createMuleContext(new SpringXmlConfigurationBuilder(
???????configFileArr));
???context.start();
??} catch (MuleException t) {
???t.printStackTrace();
??}
?}
}

?

第四步：配置mule_config.xml放在src下

<?xml version="1.0" encoding="UTF-8"?>??
<mule xmlns="http://www.mulesource.org/schema/mule/core/2.1"?
????? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"?

?????????????? ">??

??????????? </inbound>??
??????????? <component class="com.eagle.mule.test.impl.MuleServiceImp">??

??????? </service>??
??? </model>??
??? </mule>?

就可以运行EagleMuleMain得到线面这个就说明运行成功了

在浏览器里访问

如果出现xml文说明成功运行服务器。

ps：一定要加上endorsed下jar哦 这个很容易给忽略掉的，不知道别人怎么运行通过的额。
