                            nothing
                        
                    
                
                
            

mvn dependency:copy-dependencies -DoutputDirectory=F:templib  -DincludeScope=runtime

java -Dloader.path=lib/ -jar myproject-0.0.1-SNAPSHOT.jar

FROM openjdk:11-jre-slim
VOLUME /tmp
ADD myproject-0.0.1-SNAPSHOT.jar app.jar
RUN echo "Asia/Shanghai" > /etc/timezone
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime
COPY lib /lib
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Dloader.path=/lib/","-jar","/app.jar"]

注意:
1, COPY lib /lib 表示复制项目依赖到docker
2, -Dloader.path=/lib/ 表示项目启动需要依赖lib目录下的包
