java - 有没有更简单的方法将 mysql 驱动程序加载到类路径？

Question

我正在尝试命令行类路径方法，但 docker run 不断给出类未找到错误？有没有更简单的方法将 mysql 驱动程序加载到类路径？

错误:

Error:Error: Could not find or load main class com.smartworks.client.RDSConnectionTest
Caused by: java.lang.ClassNotFoundException:

我的 Dockerfile:

FROM openjdk

COPY src src

WORKDIR src

RUN mkdir -p target

COPY target/mysql-connector-java-8.0.20.jar /target/

RUN javac ./com/smartworks/client/*.java

ENTRYPOINT ["java","-cp", "mysql-connector-java-8.0.20.jar:target/*","com.smartworks.client.RDSConnectionTest"]

Answer 1

FROM openjdk
COPY src . 
COPY target/mysql-connector-java-8.0.20.jar libs/
ENV CLASSPATH=libs/mysql-connector-java-8.0.20.jar:${CLASSPATH}
RUN javac /*.java
ENTRYPOINT ["java","RDSConnectionTest"]
