dubbo框架提供Main方法运行容器的几种方式（转）
2024-10-18 16:47:14
本文使用的是dubbo提供的主类com.alibaba.dubbo.container.Main启动容器。
主要区别是提供不同插件的的启动方式。
目录
一、项目内容
1.1、目录结构图
1.2、相关文件配置
二、运行容器方式
2.1 使用Java命令启动（手动）
2.1.1 使用maven-shade-plugin 插件打包运行
2.1.2 使用 maven-jar-plugin 插件和 maven-dependency-plugin 插件打包运行
2.2 使用脚本启动
2.2.1 windows启动脚本start.bat
2.2.2 linux启动脚本start.sh
2.2.3 linux停止脚本stop.sh
2.2.4 linux重启脚本restart.sh

二、运行容器方式
2.1、使用java命令启动（手动）
2.1.1 方法一：使用maven-shade-plugin 插件打包运行
pom主要使用如下配置
<build>
<resources>
<!--主要是把src/main/resources下的所有的文件中的变量替换-->
<!--如：dubbo.properties 中的prop.log.dir=${pom.log.dir}，pom.log.dir配置在pom.xml文件中-->
<resource>
<targetPath>${project.build.directory}/classes</targetPath>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.*</include>
</includes>
</resource>
<!--dubbo 容器配置-->
<!-- 把 directory 下的 include 文件 复制到 targetPath-->
<resource>
<!--dubbo 默认指定的容器启动目录-->
<targetPath>${project.build.directory}/classes/META-INF/spring</targetPath>
<directory>src/main/resources/cconf</directory>
<filtering>true</filtering>
<includes>
<include>application.xml</include>
</includes>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.1.0</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.alibaba.dubbo.container.Main</mainClass>
</transformer>
<transformer
implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.handlers</resource>
</transformer>
<transformer
implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.schemas</resource>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
打包完成后target如下
在jar包的目录打开cmd,运行命令 java -jar hello-provider-1.0-SNAPSHOT.jar，如下图即启动成功
在dubbo-ammin 也能看到对应的注册信息
2.1.2 使用 maven-jar-plugin 插件和 maven-dependency-plugin 插件
pom主要使用如下配置
<build>
<resources>
<resource>
<targetPath>${project.build.directory}/classes</targetPath>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.*</include>
</includes>
</resource>
<!--dubbo 容器配置-->
<!-- 把 directory 下的 include 文件 复制到 targetPath-->
<resource>
<!--dubbo 默认指定的容器启动目录-->
<targetPath>${project.build.directory}/classes/META-INF/spring</targetPath>
<directory>src/main/resources/cconf</directory>
<filtering>true</filtering>
<includes>
<include>application.xml</include>
</includes>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<!-- <classesDirectory>target/classes/</classesDirectory>-->
<archive>
<manifest>
<mainClass>com.alibaba.dubbo.container.Main</mainClass>
<!-- 打包时 MANIFEST.MF文件不记录的时间戳版本 -->
<useUniqueVersions>false</useUniqueVersions>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
</manifest>
<manifestEntries>
<Class-Path>.</Class-Path>
</manifestEntries>
</archive>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<type>jar</type>
<includeTypes>jar</includeTypes>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
打包完成后target如下图
打开target目录，运行 java -jar hello-provider-1.0-SNAPSHOT.jar 即可，是否注册成功参照2.1.1图
注：该方式jar包和lib包必须在同一目录下运行java命令才能启动spring容器
2.2 使用脚本启动
dubbo也提供脚本启动方式，在dubbo-2.5.9.jar中的META-INF/assembly.bin下有提供模板文件。
使用脚本启动容器只需要使用 maven-assembly-plugin 插件即可。主要配置如下：
<build>
<resources>
<resource>
<targetPath>${project.build.directory}/classes</targetPath>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.*</include>
</includes>
</resource>
<!--dubbo 容器配置-->
<!-- 把 directory 下的 include 文件 复制到 targetPath-->
<resource>
<!--dubbo 默认指定的容器启动目录-->
<targetPath>${project.build.directory}/classes/META-INF/spring</targetPath>
<directory>src/main/resources/cconf</directory>
<filtering>true</filtering>
<includes>
<include>application.xml</include>
</includes>
</resource>
</resources>
<plugins>
<!--脚本启动使用的插件-->
<!--该插件可以做额外的文件打包，比如bin目录，conf配置文件夹。使用java 命令启动可忽略该插件-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>3.1.0</version>
<executions>
<execution>
<id>make-binary-pacakge</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<!--打包后的报名-->
<finalName>deploy-jar</finalName>
<!-- 包名是否追加assemble-descriptor.xml中的id-->
<appendAssemblyId>false</appendAssemblyId>
<descriptors>
<descriptor>src/main/resources/assemble/assemble-descriptor.xml</descriptor>
</descriptors>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
重新编译打包项目，在target下会出现两个文件：deploy-jar.zip和deploy-jar.tar.gz。windows使用deploy-jar.zip，linux使用deploy-jar.tar.gz。再上传到对应服务器上解压内容如下：
进入bin目录，windows启动使用bat，linux使用sh脚本
2.2.1 windows启动脚本start.bat
内容如下,双击start.bat即可运行，验证方式如方法一
@echo off & setlocal enabledelayedexpansion
set LIB_JARS=..\cconf
cd ..\lib
for %%i in (*) do set LIB_JARS=!LIB_JARS!;..\lib\%%i
cd ..\bin
echo Starting the server [服务名] ......
java -classpath %LIB_JARS% com.alibaba.dubbo.container.Main
endlocal
2.2.2 linux启动脚本start.sh
进入bin目录，执行./start.sh，验证方式如方法一
