maven工具引入lib下的jar文件

​

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <executable>true</executable><!-- 直接运行，注册服务 -->
                <fork>true</fork> <!-- 如果没有该配置，devtools不会生效 -->
                <includeSystemScope>true</includeSystemScope>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

1、配置includeSystemScope

2、添加依赖：

        <groupId>jave</groupId>
        <artifactId>jave</artifactId>
        <version>1.0.2</version>
        <scope>system</scope>
        <systemPath>${project.basedir}/lib/jave-1.0.2.jar</systemPath>
    </dependency> 

3、bulid添加配置：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>${java.version}</source>
                <target>${java.version}</target>
                <encoding>${project.build.sourceEncoding}</encoding>
                <compilerArguments>
                    <!-- 打包本地jar包 -->
                    <extdirs>${project.basedir}/lib</extdirs>
                </compilerArguments>
            </configuration>
        </plugin>
    </plugins>
</build>

4、打包即可；

使用jave.jar读取视频时长：

public static String readVideoTime(File source) {
    Encoder encoder = new Encoder();
    String length = "";
    try {
        System.out.println("开始解析视频时长："+source.getAbsolutePath());
        MultimediaInfo m = encoder.getInfo(source);
        long ls = m.getDuration() / 1000;
        int hour = (int) (ls / 3600);
        int minute = (int) (ls % 3600) / 60;
        int second = (int) (ls - hour * 3600 - minute * 60);
        length = (hour<10?"0":"") + hour + ":" + (minute<10?"0":"") + minute + ":" + (second < 10?"0":"") + second + "";
        System.out.println("解析视频时长结束："+length);
    } catch (Exception e) {
        length = "-";
        System.err.println(e.getMessage());
    }
    return length;
}
