使用maven将项目打成jar包

               

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <parent>  <groupId>wusc.edu.common</groupId>  <artifactId>edu-common-parent</artifactId>  <version>1.0-SNAPSHOT</version>  <relativePath>../edu-common-parent</relativePath> </parent> <groupId>wusc.edu.service</groupId> <artifactId>edu-service-user</artifactId> <version>${edu-service-user.version}</version> <packaging>jar</packaging> <name>edu-service-user</name> <url>http://maven.apache.org</url> <properties>  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  <log4j.leve>debug</log4j.leve>  <log4j.ale>debug</log4j.ale> </properties> <build>  <finalName>edu-service-user</finalName>  <resources>          <!-- 把src/main/resources下的包括xml和properties的文件复制到target/classes下 -->   <resource>    <targetPath>${project.build.directory}/classes</targetPath>    <directory>src/main/resources</directory>    <filtering>true</filtering>    <includes>     <include>**/*.xml</include>     <include>**/*.properties</include>    </includes>   </resource>   <!-- 把src/main/resources/spring下的spring-context.xml   文件复制到target/classes/META-INF/spring下 -->   <resource>    <targetPath>${project.build.directory}/classes/META-INF/spring</targetPath>    <directory>src/main/resources/spring</directory>    <filtering>true</filtering>    <includes>     <include>spring-context.xml</include>    </includes>   </resource>  </resources>  <pluginManagement>    <!--这个插件没看懂  似乎和eclipse与mavan生命周期冲突相关  -->   <plugins>    <plugin>     <groupId>org.eclipse.m2e</groupId>     <artifactId>lifecycle-mapping</artifactId>     <version>1.0.0</version>     <configuration>      <lifecycleMappingMetadata>       <pluginExecutions>        <pluginExecution>         <pluginExecutionFilter>          <groupId>org.apache.maven.plugins</groupId>          <artifactId>maven-dependency-plugin</artifactId>          <versionRange>[2.0,)</versionRange>          <goals>           <goal>copy-dependencies</goal>          </goals>         </pluginExecutionFilter>         <action>          <ignore />         </action>        </pluginExecution>       </pluginExecutions>      </lifecycleMappingMetadata>     </configuration>    </plugin>   </plugins>  </pluginManagement>  <plugins>    <!--打jar包范围是rarget/classes  启动类是 com.alibaba.dubbo.container.Main  -->   <plugin>    <groupId>org.apache.maven.plugins</groupId>    <artifactId>maven-jar-plugin</artifactId>    <configuration>     <classesDirectory>target/classes</classesDirectory>     <archive>      <manifest>       <!-- 不记录版本号 -->       <useUniqueVersions>false</useUniqueVersions>       <addClasspath>true</addClasspath>        <classpathPrefix>lib/</classpathPrefix>       <mainClass>com.alibaba.dubbo.container.Main</mainClass>      </manifest>      <manifestEntries>       <Class-Paht>.</Class-Paht>      </manifestEntries>     </archive>    </configuration>   </plugin>   <!--打jar包 项目本身的依赖包放在lib文件夹下   (lib与生成的jar在同一目录)  -->   <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>       <useUninqeVersions>false</useUninqeVersions>       <outputDirectory>        ${project.build.directory}/lib       </outputDirectory>      </configuration>     </execution>    </executions>   </plugin>  </plugins> </build> <dependencies>  <!-- dubbo 需要的jar start -->  <dependency>   <groupId>org.jboss.netty</groupId>   <artifactId>netty</artifactId>  </dependency>  <dependency>   <groupId>com.alibaba</groupId>   <artifactId>dubbo</artifactId>   <exclusions>    <exclusion>     <groupId>org.springframework</groupId>     <artifactId>spring</artifactId>    </exclusion>   </exclusions>  </dependency> </dependencies></project>

</pre>如果这个项目本身还依赖另一个项目A,那么我们就得先把项目A打成jar包使用上面的pom,然后在myeclipse中右键,run as maven install最后结果<p>如下图</p><p>lib下存放着edu-service-user运行所需要的jar</p><p>另外,我们之间在命令行下,使用java -jar edu-service-user.jar 即可调用</p><p>com.alibaba.dubbo.container.Main这个类</p><p><img src="https://img-blog.csdn.net/20160502222634711?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" />

第二种方式

<pre name="code" class="html"><plugin>      <groupId>org.apache.maven.plugins</groupId>      <artifactId>maven-shade-plugin</artifactId>      <version>1.2.1</version>      <executions>          <execution>              <phase>package</phase>              <goals>                  <goal>shade</goal>              </goals>              <configuration>                  <transformers>                      <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">                          <mainClass>com.juvenxu.mvnbook.helloworld.HelloWorld</mainClass>                      </transformer>                  </transformers>              </configuration>          </execution>      </executions>  </plugin>  

运行mvn install 后 会在target下生成两个jar包

original-xxx-0.0.1-snapshot.jar 这里面只有我们自己写的java代码的class文件

xxx-0.0.1-snapshot.jar 这里面我们依赖的jar包(会抽出里面的class文件)会和我们的代码放在一块

如下:

toyprogram里面放的是我们自己写的java代码的class文件

spring就放在org里面

还有一种方式

<plugin>              <artifactId>maven-assembly-plugin</artifactId>              <configuration>                  <appendAssemblyId>false</appendAssemblyId>                  <descriptorRefs>                      <descriptorRef>jar-with-dependencies</descriptorRef>                  </descriptorRefs>                  <archive>                      <manifest>                          <mainClass>abc.ef.sdf</mainClass>                      </manifest>                  </archive>              </configuration>              <executions>                  <execution>                      <id>make-assembly</id>                      <phase>package</phase>                      <goals>                          <goal>assembly</goal>                      </goals>                  </execution>              </executions>  </plugin>  

然后在pom文件上右键 run as->maven assembly:assembly
之后在pom的同级目录里会生成你所需要的jar

不知道怎么回事,我的myeclipse里没有maven assembly:assembly

不过可以这样run build... 然后
