Dubbo的配置及启动，provider是以jar形势打包，脚本启动很大部分内容是借鉴了dubbo官方脚本
Tomcat+Dubbo安装
1.将tomcat的webapps目录下的所有文件清空，讲Dubbo管理控制台的程序dubbo-admin-2.5.3.war放
到webapps中，并且解压命名为ROOT。
unzip dubbo.war -d ROOT
2.配置dubbo.properties
将以下地址改为你Zookeeper注册的地址。前提：已经安装过Zookeeper。
dubbo.registry.address=zookeeper://192.168.137.128:2181
3.启动tomcat
浏览：http://192.168.137.128:8080/出现以下界面
PS：JDK最好使用1.7版本，因为dubbo使用的Spring版为2.X 具体原因也说不清楚，我最早部署时也是使用JDK1.8 启动tomcat时报错：
RROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'uriBrokerService': Cannot create inner bean '(inner bean)' of type [com.alibaba.citrus.service.uribroker.impl.URIBrokerServiceImpl$URIBrokerInfo] while setting bean property 'brokers' with key [0]; nested excepti on is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#25': Cannot create inner bean 'server' of type [com.alibaba.citrus.service.uribroker.uri.GenericURIBroker] while setting constructor argument; nested exception is org.springframework.beans.fact ory.BeanCreationException: Error creating bean with name 'server': Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'URIType' of bean class [com.alibaba.citrus.service.uribroker.uri.GenericURIBroker]: Bean property 'URIType' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?解决方案可以参考：https://github.com/alibaba/dubbo/issues/50
为了省事我是将JDK降到1.7 。

ps :spring-context.xml文件中对其他xml的引入地址要写成：
<import resource="classpath:spring/spring-mybatis.xml" />
<import resource="classpath:spring/applicationContext.xml" />
原因是我们在打包配置时将spring-context.xml文件复制到META-INF/spring下，如果还是使用相对地址配置就出错了找不到文件
OK打包部署。

ps:Dubbo是通过JDK的ShutdownHook来完成优雅停机的，所以如果用户使用"kill -9 PID"等强制关闭指令，是不会执行优雅停机的，只有通过"kill PID"时，才会执行。
