maven导入本地jar包

<dependency>
            <groupId>com.qrcode</groupId>
            <artifactId>qrcode</artifactId>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/webapp/WEB-INF/lib/QRCode.jar</systemPath>
            <version>1.0.0</version>
</dependency>

groupId、artifactId、version随便写，systemPath写对就ok
