maven打包dubbo服务接口（maven-assembly-plugin）--zip

dubbo 服务只需要提供service层接口，并不需要用servlet容器。完全打成其他的包直接去跑，dubbo接口性能就不会因为tomcat的限制。

dubbo 容器的加载内容可以扩展，内置了spring, jetty, log4j等加载，可通过Container扩展点进行扩展，参见：Container Spring Container 。

dubbo 容器自动加载META-INF/spring目录下的所有Spring配置。 所以spring 及dubbo 的相关配置要放在/META-INF/spring 目录下。
也可以在启动参数中配置：(配在java命令-D参数或者dubbo.properties中) dubbo.spring.config=classpath*:/META-INF/spring/*.xml  ----配置spring配置加载位置。

打包配置如下：

配置中指定了打包使用的 src/main/assembly/assembly.xml 配置文件：

[html]  view plain  copy

1. <assembly>  
2.     <id>assembly</id>  
3.     <formats>  
4.         <format>tar.gz</format>

10.             <outputDirectory>bin</outputDirectory>  
11.             <fileMode>0755</fileMode>  
12.         </fileSet>  
13.     </fileSets>  
14.     <dependencySets>  
15.         <dependencySet>  
16.             <outputDirectory>lib</outputDirectory>  
17.             <scope>runtime</scope>  
18.         </dependencySet>  
19.     </dependencySets>  
20. </assembly>  

assembly.xml 配置文件指定了bin目录和打包后的jar 存放的位置lib目录。

dubbo 服务工程目录结构如下：

使用maven 命令打包，打包后为tar 包，解压后，运行start.bat（start.sh。相关的脚本请到上传是资源中下载）即可启动dubbo 服务。如果要在本地测试，可以写一个main 方法，直接加载spring 及dubbo的相关配置即可启动dubbo的服务

测试工程说明：

dubbo-api            dubbo 服务接口定义及数据传递的类的定义。定义了接口TicketApi和传递数据的类 TicketDTO。被dubbo-service 和 dubbo-test 依赖

dubbo-service     dubbo 服务接口实现。maven打包的配置及assembly.xml 配置文件在这工程。包含了DubboServerMain ，直接加载spring 及dubbo 配置，对外提供服务，用于测试

dubbo-test            测试。直接加载配置文件， 订阅zookeeper 中提供的服务

工程使用 spring+dubbo+zookeeper ，把服务注册到zookeeper中，相关配置不再说明。

如上面工程打包后为：dubbo-service-1.0.0-assembly.tar.gz 文件，解压后有bin和lib 两个文件夹。bin中放的是脚本，lib 放的就是jar包。使用脚本启动（zookeeper 要启动），运行测试代码即可。

说明：

要把dubbo-api 工程install 到本地maven仓库，dubbo-service 、dubbo-test 才能编译通过。

assembly.xml 配置文件中有  STDOUT_FILE=$LOGS_DIR/stdout.log ，说明了日志文件的路径。 也指定了打包的文件格式tar.gz
