人类的天性是容易忘记感激别人，所以，如果我们施一点点恩惠都希望别人感激的话，那一定会使我们大为头痛。——戴尔·卡耐基
首先是下载：
下载 - 云信令（原实时消息） - 文档中心 - 声网Agora
Agora_RTM_SDK_for_Linux_Java_v1_5_1.zip其中有个samples/Agora-RTM-Tutorial-Java，我们将
libs/libagora_rtm_sdk.so
libs/agora_rtm.jar
复制到samples/Agora-RTM-Tutorial-Java/lib下
然后在samples/Agora-RTM-Tutorial-Java下执行命令：
mvn install:install-file -Dfile=lib/agora_rtm.jar -DgroupId=io.agora.rtm -DartifactId=agora-rtm-sdk -Dversion=1.0 -Dpackaging=jar
然后注意修改代码中的AppId和token
这里我的token采取服务端生成，因此我们还需要这一个jar
<dependency> <groupId>io.agora</groupId> <artifactId>authentication</artifactId> <version>2.0.0</version> </dependency>
代码：
String token = new RtmTokenBuilder2().buildToken(appId, appCertificate, userId, 3600);
其次是Dockerfile，我放在Agora-RTM-Tutorial-Java下
# 使用基础的Java 8镜像（包含编译工具）作为基础 FROM openjdk:17-jdk # 设置工作目录 WORKDIR /app # 复制示例代码和Agora RTM库文件到容器中 COPY . /app # 暴露所需的端口，如果需要的话 EXPOSE 8080 # 编译示例代码 RUN javac -cp lib/agora_rtm.jar:lib/agora_rtm.jar:lib/authentication-2.0.0.jar:lib/commons-codec-1.11.jar -d . src/main/java/io/agora/RtmJavaDemo.java # 定义入口命令来运行示例代码 CMD ["java", "-cp", "lib/*:.", "-Djava.library.path=/app/lib", "io.agora.RtmJavaDemo"]
然后是构建镜像、运行
docker build -t agora-rtm-demo:java17 . docker run -it --rm -p 8080:8080 agora-rtm-demo:java17
然后杯具了，不支持mac的AARCH64架构芯片
