1　　　　重点关注

1.1　　　　本节内容

使用dubbo内置main打包jar启动

1.2　　　　主要改动点

涉及父项目，common项目，service和api项目共4个，

涉及

a　　service的 pom文件引入build

b　　service的 pom文件修改打包方式为jar包

c　　上述操作完成后 右键service子项目，maven ->update project ->选中service子项目，点击ok，进行pom文件依赖的jar包更新

d　　右键父项目，run as maven install,注意：这个方法生成了api jar包，解决了昨天一直生成不了apijar包的问题

e        进入service子项目生成的target路径下，cmd  运行 java -jar imooc-dubbo-item-service.jar

f　　  等待运行完成即可

  • a　　service的 pom文件引入build

pom.xml引用以下build

--<targetPath>${project.build.directory}/classes</targetPath>  可以将资源文件打进包里

--<targetPath>${project.build.directory}/classes/META-INF/spring</targetPath>  spring-context.xml已经聚合了所有的spring相关的配置文件（可以参考上节，也可以看下spring-context.xml）

--<artifactId>lifecycle-mapping</artifactId>   可以排除运行时的一些小问题，注意，首次加载要下载

--<artifactId>maven-jar-plugin</artifactId>  打包的方式，打完包，依赖都会有

--<mainClass>com.alibaba.dubbo.container.Main</mainClass> dubbo内置容器的container进行打包

  • b　　service的 pom文件修改打包方式为jar包
<packaging>jar</packaging>

1.3　　　　使用dubbo内置main打包方式的时候，线上如何处理？

需要把target 拷贝出来到你的服务器，文件夹名字根据自己公司规范写即可

    <import resource="classpath:spring/applicationContext-dao.xml"/>
    <import resource="classpath:spring/applicationContext-dubbo-provider.xml"/>
    <import resource="classpath:spring/applicationContext-service.xml"/>
