基于dubbo从传统MVC架构转向SOA架构分布式设计4--（服务部署集群搭建及负载均衡）

这篇文章接着下一步是建我们的服务进行打包发布；

我就不去过多开那么多虚拟机了，还是上次那两台

1.把soa-user-core打包成.tar.gz

1.1找出我们下载的源码dobbo-demo-provider,添加assembly，因为打包tar.gz需要用到这个;

在soa-user-core下的pom.xml添加如下内容：

<build>
		<plugins>
			<!-- <plugin>  
		        <groupId>org.apache.maven.plugins</groupId>  
		        <artifactId>maven-war-plugin</artifactId>  
		        <version>3.0.0</version>  
		        <configuration>  
		            <failOnMissingWebXml>false</failOnMissingWebXml>  
		        </configuration>  
		    </plugin>   -->
		    <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>2.5.7</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>

说明：build就这些就行了，其他不要
然后接着复制dobbo-demo-provider项目下的src/main/assembly下的所有文件，然后把conf下的dubbo.properties替换成我们的，结构如下：

说明：assembly.xml就不需要修改了，我们路径弄一样就好了

2.把soa-user-web打包成war

2.1修改pom.xml

<packaging>war</packaging>

<build>
  	<plugins>
  		<plugin>  
	        <groupId>org.apache.maven.plugins</groupId>  
	        <artifactId>maven-war-plugin</artifactId>  
	        <version>3.0.0</version>  
	        <configuration>  
	            <failOnMissingWebXml>false</failOnMissingWebXml>  
	        </configuration>  
	    </plugin>  
  	</plugins>
  </build>

注意：如果不修改上面的build的话会报这么个错：

Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.2:war (default-war) on project soa-consumer-web: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode)

如果WebRoot/WEB-INF/web.xml文件不存在，则按上面的方式配置。如果存在着按以下配置：

<plugins>  
    <plugin>  
        <groupId>org.apache.maven.plugins</groupId>  
        <artifactId>maven-war-plugin</artifactId>  
        <version>3.0.0</version>  
        <configuration>  
            <webResources>  
                <resource>  
                    <directory>WebRoot</directory>  
                </resource>  
            </webResources>  
        </configuration>  
    </plugin>  
</plugins>

3.打包开始
3.1右击soa-parent项目，run configurations,输入clean install执行即可

3.2打包后我们看下soa-user-core/target里：
