一、用maven-shade-plugin打包

  在pom.xml文件中加入如下信息,利用Maven的maven-shade-plugin插件进行打包。

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>1.4</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                        <configuration>
                            <filters>
                                <filter>
                                    <artifact>*:*</artifact>
                                    <excludes>
                                        <exclude>META-INF/*.SF</exclude>
                                        <exclude>META-INF/*.DSA</exclude>
                                        <exclude>META-INF/*.RSA</exclude>
                                    </excludes>
                                </filter>
                            </filters>
                            <transformers>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                    <!-- 程序主入口 -->
                                    <mainClass>net.test.HelloWorld</mainClass>
                                </transformer>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                    <resource>META-INF/spring.handlers</resource>
                                </transformer>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                    <resource>META-INF/spring.schemas</resource>
                                </transformer>
                            </transformers>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

  其中<mainClass>net.test.HelloWorld</mainClass>标签中配置的是项目程序的主入口,加入插件信息后的最终pom.xml文件如下:

<?xml version="1.0" encoding="UTF-8"?>

                                </transformer>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                    <resource>META-INF/spring.handlers</resource>
                                </transformer>

                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

    <dependencies>
        <dependency>
            <groupId>com.googlecode.log4jdbc</groupId>
            <artifactId>log4jdbc</artifactId>

        </dependency>
    </dependencies>
</project>

  然后就可以执行以下Maven命令进行打包了:

mvn clean compile //清除之前target编译文件并重新编译
mvn clean package //对项目进行打包(因为配置过插件,所以jar包是可执行的)
mvn clean install //安装项目,然后就可以使用了

  也可以使用IDEA自带的maven管理工具代替执行上面的命令,如下图所示,依次点击蓝色的部分即可打包成功:

测试:

  打好包后,找到jar包位置,在jar包所在文件夹空白处 Shift + 右击——在此处打开命令窗口,通过 java -jar 包名.jar 命令即可运行,如下图所示:

  即将Maven项目打包为cmd可执行jar成功!

二、用maven-assembly-plugin打包

  在pom.xml文件中加入如下信息,利用Maven的maven-assembly-plugin插件进行打包。

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
        <archive>
            <manifest>
                <mainClass>net.test.HelloWorld</mainClass>
            </manifest>
        </archive>
    </configuration>
    <executions>
        <execution>
            <id>make-assembly</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>

  其中<mainClass>net.test.HelloWorld</mainClass>标签中配置的是项目程序的主入口,然后就可以执行以下Maven命令进行打包了:

mvn assembly:assembly

  也可以使用IDEA自带的maven管理工具代替执行上面的命令:

技术图片

  测试如上!!!

   注:成功后的jar包中META-INF 目录中的 MANIFEST.MF,内容如下(下列属性冒号后有一空格):

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Built-By: BigBoss
Created-By: Apache Maven 3.3.9
Build-Jdk: 1.8.0_131
Main-Class: net.test.HelloWorld
