java使用opencv处理图片，idea运行程序，报错异常信息：

Exception in thread "main" java.lang.UnsatisfiedLinkError: no opencv_java490 in java.library.path: /Users/carter/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:.

 at java.base/java.lang.System.loadLibrary(System.java:1989)
 at org.jeecg.test.PanoramaStitching6.<clinit>(PanoramaStitching6.java:16)

Process finished with exit code 1

异常情况如下图所示：

1、异常情况分析
需要加载opencv库，看很多资料给出建议是System.loadLibrary(Core.NATIVE_LIBRARY_NAME)，但是任然出现错误异常。

    static {
        System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    }

2、解决方案
引入maven依赖，加载opencv java库Loader.load(opencv_java.class)。

         <dependency>
            <groupId>org.bytedeco</groupId>
            <artifactId>opencv-platform</artifactId>
            <version>4.9.0-1.5.10</version>
        </dependency>


    static {
        Loader.load(opencv_java.class);
//        System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    }
