【maven】-001用maven assembly插件打jar包实现依赖包归档

服务化代码层次结构

一、采用mvn生成对应的包

自动将项目依赖的jar包打到web-inf 下的lib文件夹中

jar， 使用 maven的 assembly插件， 会在${project}/target 文件夹下发现新生成的 {artifactId}-jar-with-dependencies.jar 这个文件

二、如何配置assembly插件

                   < groupId   > org.apache   </ groupId   >
                   < artifactId   > zookeeper   </ artifactId   >
                   < version   > 3.4.5   </ version   >

      </ dependencies   >
      < build   >
              < plugins   >
                   < plugin   >
                        < groupId   > org.apache.maven.plugins   </ groupId   >
                        < artifactId   > maven-compiler-plugin   </ artifactId   >

                              < source   > 1.6   </ source   >
                              < target   > 1.6   </ target   >
                              < encoding   > UTF-8   </ encoding   >
                        </ configuration   >
                   </ plugin   >
                   <plugin >
                      <artifactId >maven-assembly-plugin </artifactId >
                      <version >2.2-beta-5 </version >
                      <configuration >
                            <descriptors >
                                 <descriptor >src/main/assembly/src.xml </descriptor >
                            </descriptors >
                      </configuration >
                 </plugin >
              </ plugins   >
      </ build   >
</ project >

（2） 在 main/assembly 下创建 src.xml文件，其中src.xml中的内容

< assembly
      xmlns = "http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
      xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation = "http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd" >
      < id   > jar-with-dependencies   </ id   >
      < formats   >
              < format   > jar   </ format   >
      </ formats   >
      < includeBaseDirectory   > false   </ includeBaseDirectory   >
      < dependencySets   >
            <dependencySet >
                 <unpack >false </unpack >
                 <scope >runtime </scope >
            </dependencySet >
      </ dependencySets   >
      < fileSets   >
              < fileSet   >
                   < directory   > ${project.build.outputDirectory}   </ directory   >
              </ fileSet   >
      </ fileSets   >
</ assembly >

（3）命令行输入mvn assembly:assembly

      会在 ${project}/target  文件夹下发现新生成的  {artifactId}-jar-with-dependencies.jar  这个文件

 （4） 下载对应的依赖包并查看
