Dubbo（七）------服务运行的三种方式

缺乏、安全感 2023-07-01 08:58 37阅读 0赞

**1、使用Servlet容器运行（Tomcat、Jetty等），不推荐**

即把工程做成web工程，在web.xml里面启动spring，然后在spring中启动dubbo服务。dubbo服务随着tomcat启动而启动了。但是这种方式并不推荐使用，因为它增加了复杂性，浪费了内存资源。

**2、自建main方法来运行，这种方式适合本地调试**

[Dubbo（三）------Dubbo入门示例(基于XML配置)][Dubbo_------Dubbo_XML]

**3、使用dubbo框架提供的main方法来运行(推荐使用)**

优点：框架本身提供（com.alibaba.dubbo.container.Main），可是实现优雅关机（ShutdownHook）

现在介绍第三种方式如何使用的

主要利用maven的maven-jar-plugin和maven-dependency-plugin插件，前一个插件是配置可运行jar的manifest清单文件，该清单文件主要配置主程序main所在的位置还有依赖的jar包的位置。由于dubbo启动类 com.alibaba.dubbo.container.Main 默认自动加载META-INF/spring目录下的所有Spring配置，所以我们还需要把spring的配置文件通过maven拷贝到指定目录。除此之外，packaging的构建包类型修改为jar
