在本地部署没有问题，但是通过docker-compose部署到docker环境中就出现以下异常：
Caused by: java.lang.NoClassDefFoundError: Could not initialize class sun.awt.X11FontManager
或
com.alibaba.excel.exception.ExcelGenerateException: java.lang.UnsatisfiedLinkError: /usr/local/jdk-11.0.11/lib/libfontmanager.so: libfreetype.so.6: cannot open shared object file: No such file or directory
经过排查是由于docker环境中缺少字体文件造成的
修改dockerfile，增加以下配置：
COPY dejavu /usr/share/fonts
全部dockerfile配置文件如下
FROM harbor.minexiot.com/base/jdk:11.0.11
# 设置环境变量为 UTF-8 编码
ENV LANG C.UTF-8
ENV LC_ALL C.UTF-8
ARG JAR_PATH=./
ARG APP_NAME=svc-icp
ENV JAVA_OPTS ""
ENV NACOS_SERVER_ADRESS "nacos"
ENV NACOS_CONFIG_NAMESPACE "docker"
WORKDIR /services
COPY "${JAR_PATH}${APP_NAME}.jar" "/services/${APP_NAME}.jar"
COPY run.sh /services
#COPY wind /usr/share/fonts/
#RUN fc-cache -fv
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
RUN echo 'Asia/Shanghai' > /etc/timezone
RUN apt update
RUN apt install fontconfig -y
COPY dejavu /usr/share/fonts
EXPOSE 8080 5004
CMD ["sh", "run.sh"]
