我正在尝试生成具有以下特征的 docker 映像所以--> 免费：18.04Java --> openjdk-11-jdkOpenCV --> 3.4.2 版本我能够成功生成图像，但 lib 文件夹中未生成 java342 文件，我收到此异常：java.library.path 中没有 opencv_java342我使用以下命令作为入口点启动我的应用程序：java -Djava.library.path=/var/lib/opencv-3.4.2/build/lib -jar Application.jarDocker 文件FROM ubuntu:18.04RUN apt-get updateRUN apt-get install -y antRUN apt-get install -y openjdk-11-jdkARG JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"ENV JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"RUN echo $JAVA_HOMERUN apt-get install -y wgetRUN apt-get install -y cmakeRUN apt-get install -y g++RUN apt-get install -y unzipRUN apt-get install -y vimRUN java -versionRUN wget https://github.com/opencv/opencv/archive/3.4.2.zipRUN unzip 3.4.2.zip -d /var/lib/RUN mkdir /var/lib/opencv-3.4.2/buildWORKDIR /var/lib/opencv-3.4.2/buildRUN cmake -DBUILD_SHARED_LIBS=OFF ..RUN make -j8所以我想知道我是否在docker文件或openCV编译过程中遗漏了一些东西。注意：如果我在本机计算机中执行相同的进程，一切都会按预期进行有什么建议么？

使用 Java 打开 CV 4.8
此 Docker 文件下载源代码并在 Debian 容器中构建 OpenCV
映像包含 Java Jar (opencv-480.jar) 和相应的共享库 (libopencv_java480.so)。Java <> OpenCV 互操作需要这些
所有传递依赖的 .so 库都被复制到该
opencvlibs目录中。如果您在 Debian Linux 上部署，请将 的内容复制opencvlibs到您的libs目录。Linux 将按照惯例找到它们
使用Java运行：
Jar 必须位于类路径上
.so 必须通过指定
java.library.path
Docker 文件：

我遇到了类似的问题，我从您的帖子中注意到缺少两件事
在 OpenCV 编译过程文件中，在“OpenCV 模块：要构建：”部分中，我没有看到 java.lang. 根据官方文档java肯定是有的。
检查 CMake 的输出并确保 java 是“待构建”模块之一。如果没有，您可能缺少依赖项。
我在你的 Dockerfile 中没有看到 Python，但你需要它。这是官方文档中提到的要求。
为了使用 Java 绑定构建 OpenCV，您需要安装 JDK（Java 开发工具包）（我们建议 Oracle/Sun JDK 6 或 7）、Apache Ant 和 Python v2.6 或更高版本。
我用了这条线
RUN apt-get install -y python3.8
奇怪的是，当我添加 python 时，java 包含在“要构建的 OpenCV 模块”中

将libopencv_java342.so文件从复制/usr/local/lib到/usr/lib。
如果.so未生成文件，请尝试以下操作：
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr ..
