maven打包dubbo

以前剛開始學習dubbo的時候，曾寫過一個入門的小例子，當時生產者也是用tomcat去跑的，其實dubbo只須要提供service層接口就行了，並不須要和http相關的東西，因此其實並不須要用tomcat去跑，咱們徹底打成其餘的包直接去跑，這樣dubbo接口也不會tomcat性能的限制，而打包能夠說是maven最擅長的事情之一，今天就記錄一下咱們公司的實際項目中使用maven-assembly-plugin打包的方法。

1. 首先在pom文件中，添加maven-assembly-plugin插件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<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>

在該插件的第四行咱們指定了一個assembly.xml文件，下面咱們就看看assembly.xml的內容

2. assembly.xml文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

<assembly>     <id>assembly</id>     <formats>         <format>tar.gz</format>     </formats>     <includeBaseDirectory>true</includeBaseDirectory>     <fileSets>         <fileSet>             <outputDirectory>/</outputDirectory>             <includes>                 <include>README.txt</include>             </includes>         </fileSet>         <fileSet>             <directory>src/main/scripts</directory>             <outputDirectory>/bin</outputDirectory>         </fileSet>     </fileSets>     <dependencySets>         <dependencySet>             <useProjectArtifact>true</useProjectArtifact>             <outputDirectory>lib</outputDirectory>         </dependencySet>     </dependencySets> </assembly>

該文件的第四行中的tar.gz指的就是打包的文件格式，對於Linux用戶，對這個格式必定很是熟悉，固然你們也能夠指定爲zip格式，另外在該文件的第十五行，指定了一個scripts文件夾，那麼這裏面放的又是什麼呢？咱們知道打包以後的系統咱們要跑起來才能用，那麼這裏面放的就是對咱們的系統操做的一些腳本，打包以後，咱們的系統都是一些jar文件，放在了倒數第四行指定的lib文件中，而這些腳本則放在了和lib同級的bin文件中，下面就讓咱們一一看看scripts中幾個文件的內容

至於這些文件是幹嗎的，相信做爲一個程序猿不用老夫一一解釋了，聰明如您，必定一眼就能看出來了，若是您的shell水平目前還不夠，能夠先看看老夫的這篇文章，看完以後再看這幾個腳本能夠說徹底無壓力。
