dubbo的启动方法

Dubbo服务的运行方式：

1、使用Servlet容器运行（Tomcat、Jetty等）----不可取 缺点：增加复杂性（端口、管理） 浪费资源（内存）
2、自建Main方法类来运行（spring容器） ----不建议（本地调试可用） 缺点： Dobbo本身提供的高级特性没用上 自已编写启动类可能会有缺陷
3、使用Dubbo框架提供的Main方法类来运行（Spring容器）----建议使用 优点：框架本身提供（com.alibaba.dubbo.Container.Main） 可实现优雅关机（ShutdownHook）
注意点： spring-context.xml <import resource="classpath:spring/spring-xxx.xml" />

一、服务的启动方式：servelet容器过于庞大，占用资源。
二、main方法在本地用的比较普遍，本地开发调试，单元测试，要掌握，不建议生产使用。
三、dubbo提供的启动类：建议使用dubbo服务自带的启动类，好处是优雅关机，避免强行关闭导致数据丢失。

以下是dubbo服务的打包及启动配置，打出jar包的服务：

  95.             </plugin>  
  96.         </plugins>  
  97.   
  98.     </build>  



五、启动jar包，定位到相应的目录下，执行  java -jar edu-service-user.jar &

修改spring-context.xml文件中对另外两个文件的引用路径：前面加上classpath:spring/spring-mybatis.xml

六、当然了，我们的服务是war包，直接部署在tomcat就ok了。配置如下：

    1. <build>  
    2.     <finalName>****-service</finalName>  
    3.     <resources>

    5.             <targetPath>${project.build.directory}/classes</targetPath>  
    6.             <directory>src/main/resources</directory>  
    7.             <filtering>true</filtering>  
    8.             <includes>  
    9.                 <include>**/*</include>  
    10.             </includes>  
    11.         </resource>
