maven打包dubbo接口之最佳实践
之前刚开始学习dubbo的时候,曾写过一个入门的小例子,当时生产者也是用tomcat去跑的,其实dubbo只需要提供service层接口就好了,并不需要和http相关的东西,所以其实并不需要用tomcat去跑,我们完全打成其他的包直接去跑,这样dubbo接口也不会tomcat性能的限制,而打包可以说是maven最擅长的事情之一,今天就记录一下我们公司的实际项目中使用maven-assembly-plugin打包的方法。
1. 首先在pom文件中,添加maven-assembly-plugin插件
<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>
在该插件的第四行我们指定了一个assembly.xml文件,下面我们就看看assembly.xml的内容
2. assembly.xml文件
<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>
该文件的第四行中的tar.gz指的就是打包的文件格式,对于Linux用户,对这个格式一定非常熟悉,当然大家也可以指定为zip格式,另外在该文件的第十五行,指定了一个scripts文件夹,那么这里面放的又是什么呢?我们知道打包之后的系统我们要跑起来才能用,那么这里面放的就是对我们的系统操作的一些脚本,打包之后,我们的系统都是一些jar文件,放在了倒数第四行指定的lib文件中,而这些脚本则放在了和lib同级的bin文件中,下面就让我们一一看看scripts中几个文件的内容

至于这些文件是干嘛的,相信作为一个程序猿不用老夫一一解释了,聪明如您,一定一眼就能看出来了,如果您的shell水平目前还不够,可以先看看老夫的这篇文章,看完之后再看这几个脚本可以说完全无压力。

具体怎么将接口打包啊???不懂啊
就用maven命令打包,和其他的没有区别。用这种方法打包之后,会出现一个tar.gz文件,解压之后有一个bin和lib,bin里面就是这几个可执行文件,直接运行就好了
