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)

[2015-05-25 15:17:39] Dubbo service server started!
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
