“ Java.lang.UnsatisfiedLinkError：java.library.path中没有opencv_java320”

请在下面找到有效的代码段。您需要适应您的需求。

假设以下文件结构

libsopencv_java320.dllpom.xmlsrctestjavasuboptimalOpenCVTest.java

pom.xml- 测试部分

<build>    <plugins>        <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.20</version> <configuration>     <argLine>-Djava.library.path=${project.basedir}/libs/</argLine> </configuration>        </plugin>    </plugins></build>

子最优 OpenCVTest.java

package sub.optimal;import org.junit.Test;public class OpenCVTest {    @Test    public void someOpenCVTest() {        System.out.printf("java.library.path: %s%n",     System.getProperty("java.library.path"));        System.loadLibrary("opencv_java320");    }    }

运行测试

mvn compile test

输出
