Docker + Java + OpenCV，java.library.path中没有openc

Question

我正在尝试生成具有以下特征的 docker 映像

• 所以--> 免费：18.04

• Java --> openjdk-11-jdk

• OpenCV --> 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.jar

Docker 文件

FROM ubuntu:18.04

RUN apt-get update

RUN apt-get install -y ant

RUN apt-get install -y openjdk-11-jdk

ARG JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"

ENV JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"

RUN echo $JAVA_HOME

RUN apt-get install -y wget

RUN apt-get install -y cmake

RUN apt-get install -y g++

RUN apt-get install -y unzip

RUN apt-get install -y vim

RUN java -version

RUN wget https://github.com/opencv/opencv/archive/3.4.2.zip

RUN unzip 3.4.2.zip -d /var/lib/

RUN mkdir /var/lib/opencv-3.4.2/build

WORKDIR /var/lib/opencv-3.4.2/build

RUN 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.pathDocker 文件：FROM debian:11 AS opencv-libs# Install minimal prerequisites (Ubuntu 18.04 as reference)# Build tools for OpenCV# libavcodec, libavformat, libswscale, libavutil, libswresample are needed by ffmpeg.

Answer 2

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.&nbsp;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&nbsp;apt-get&nbsp;install&nbsp;-y&nbsp;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&nbsp;-D&nbsp;CMAKE_BUILD_TYPE=Release&nbsp;-D&nbsp;CMAKE_INSTALL_PREFIX=/usr&nbsp;..
