1、用maven-shade-plugin打包

　　在pom.xml文件中加入以下信息，利用Maven的maven-shade-plugin插件進行打包。html

<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>標籤中配置的是項目程序的主入口，加入插件信息後的最終pom.xml文件以下：java

                        <configuration>
                            <filters>
                                <filter>
                                    <artifact>*:*</artifact>
                                    <excludes>

                                <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">

                                </transformer>
                            </transformers>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

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

        </dependency>
        <dependency>
            <groupId>oracle</groupId>
            <artifactId>ojdbc7</artifactId>

        </dependency>
        <dependency>

        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>

            <version>2.7</version>
        </dependency>
        <dependency>

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

　　而後就能夠執行如下Maven命令進行打包了：mysql

mvn clean compile //清除以前target編譯文件並從新編譯
mvn clean package //對項目進行打包(由於配置過插件，因此jar包是可執行的)
mvn clean install //安裝項目，而後就能夠使用了

　　也能夠使用IDEA自帶的maven管理工具代替執行上面的命令，以下圖所示，依次點擊藍色的部分便可打包成功：spring

測試：sql

　　打好包後，找到jar包位置，在jar包所在文件夾空白處 Shift + 右擊——在此處打開命令窗口，經過 java -jar 包名.jar 命令便可運行，以下圖所示：apache

　　即將Maven項目打包爲cmd可執行jar成功！json

2、用maven-assembly-plugin打包

　　在pom.xml文件中加入以下信息，利用Maven的maven-assembly-plugin插件進行打包。api

<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>標籤中配置的是項目程序的主入口，而後就能夠執行如下Maven命令進行打包了：oracle

mvn assembly:assembly

　　也能夠使用IDEA自帶的maven管理工具代替執行上面的命令：maven

　　測試如上！！！

　　注：

　　成功後的jar包中META-INF 目錄中的 MANIFEST.MF，內容以下（下列屬性冒號後有一空格）：

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
