dubbo提供者打包,解决jar不能正常运行(不能注册到注册中心)

这几天打包发布dubbo提供者,出现了各种问题.

今天记录的是直接在Eclispe是运行Main方法时正常使用服务.打包成jar在服务运行时不能正常使用问题.

我写的Main方法:

public class BannerProvider {    public static void main(String[] args) {        com.alibaba.dubbo.container.Main.main(args);    }    }

查找了几天,翻了N文档.后来死心了..一行一行看看控制台的每一行log找到了解决方案(发现自己以前老是说别人不看控制台,我现在也懒了不想去看控制台信息..看到得好好反省反省了)

这个是直接运行jar包控制台所输出的信息.

其中日志显示加载到0个配置信息. 

 Loaded 0 bean definitions from location pattern [classpath*:META-INF/spring/*.xml]

记得以前运行dubbo的demo时是正常的.

这次重新去看了dubbo的打包配置.

=================

解决方案

=================

再pom.xml中添加了这几行

<build><plugins><plugin><artifactId>maven-dependency-plugin</artifactId><executions><execution><id>unpack</id><phase>package</phase><goals><goal>unpack</goal></goals><configuration><artifactItems><artifactItem><groupId>com.alibaba</groupId><artifactId>dubbo</artifactId><version>2.5.3</version><outputDirectory>${project.build.directory}/dubbo</outputDirectory><includes>META-INF/assembly/**</includes></artifactItem></artifactItems></configuration></execution></executions></plugin><plugin><artifactId>maven-assembly-plugin</artifactId>                <configuration>                    <descriptor>src/main/assembly/assembly.xml</descriptor>                </configuration>                <executions><execution><id>make-assembly</id><phase>package</phase><goals><goal>single</goal></goals></execution></executions>            </plugin></plugins></build>

还需要在添加一个xml src/main/assembly/assembly.xml,一开始我是直接复制了dubbo下的.但是本人有强迫症把文件改了.你可以自己去下载原来的dubbo原来的点这下载

PS:为了修改这个我还去apache查看了Assembly怎么配置(主要是添加了单个文件的拷贝)  官方文档

重新打包 在target下生成了hequ-banner-provide-0.0.1-assembly.tar.gz 解压重新在bin正面运行对应有脚本.程序成功运行
