maven项目打包成可执行jar

打包成可执行的jar

方法一：使用maven-jar-plugin和maven-dependency-plugin

<build>
    <plugins>
        <!-- maven-jar-plugin的作用是配置mainClass和指定classpath -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>3.2.0</version>
            <configuration>
                <archive>
                    <manifest>
                        <addClasspath>true</addClasspath>
                        <classpathPrefix>libs/</classpathPrefix>
                        <mainClass> <!-- mainClass替换成实际的 -->
                            com.test.App
                        </mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
        <!-- maven-dependency-plugin会把所依赖的jar包copy到指定目录 -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <id>copy-dependencies</id>
                    <phase>prepare-package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>
                            ${project.build.directory}/libs
                        </outputDirectory>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

方法二：使用maven-assembly-plugin

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>3.3.0</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                    <configuration>
                        <archive>
                            <manifest>
                                <mainClass> <!-- mainClass替换成实际的 -->
                                    com.test.App
                                </mainClass>
                            </manifest>
                        </archive>
                        <descriptorRefs>
                            <descriptorRef>jar-with-dependencies</descriptorRef>
                        </descriptorRefs>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

方法三：使用spring-boot-maven-plugin

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>2.7.9</version>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                    <configuration>
                        <classifier>spring-boot</classifier>
                        <mainClass>
                            com.deri.App
                        </mainClass>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

总结

使用上述任一方法，通过mvn clean package命令打包后, 可以直接java -jar xxxx.jar运行程序.
