码头集装箱中的spire.pdf

Question

我创建了一个处理pdf并将它们转换为pdfa3的应用程序，并将文档转换为facturX。我使用Springboot开发了我的应用程序，它运行得很好。现在我在尝试修改我的申请。我对数据库连接有问题，现在我遇到了以下问题

facturx_1  | 2022-03-21 16:20:55.565 ERROR 1 --- [nio-8080-exec-2] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is class com.spire.ms.System.Exception: No 'Arial' font found!

facturx_1  |    at fr.company.app.ui.controller.FacturXController.createFacturXOutoutStream(FacturXController.java:54) ~[classes!/:0.0.1-SNAPSHOT]

我的代码如下：

public static PDDocument loadPdfA3(String pdfData) {
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

    byte[] decoded = Base64.getDecoder().decode(pdfData);
    InputStream inputStream = new ByteArrayInputStream(decoded);

    PdfStandardsConverter converter = new PdfStandardsConverter(inputStream);
    converter.toPdfA3B(outputStream);

    byte[] pdfBytes = outputStream.toByteArray();
    InputStream pdfInputStream = new ByteArrayInputStream(pdfBytes);

    try {
        return PDDocument.load(pdfInputStream);
    } catch (IOException e) {
        throw new AppServiceException(e.getLocalizedMessage());
    }
}

返回异常的行是以下converter.toPdfA3B(outputStream)

我实现了以下docker文件：

# Build stage
FROM maven:3.8.4-openjdk-11 AS build
WORKDIR /app
COPY . /app
RUN mvn clean package -DskipTests

# Package and Run stage
FROM openjdk:11.0.14.1-jre
COPY --from=build app/target/facturx-ws.jar /usr/local/lib/facturx-ws.jar
EXPOSE 8092

ENTRYPOINT ["java", "-jar", "-Dspring.profiles.active=docker", "/usr/local/lib/facturx-ws.jar"]

这里也是我的船坞组合：

version: "3"
services:
  facturx:
    container_name: facturx
    image: facturx
    restart: always
    build:
      context: ./
      dockerfile: Dockerfile
    ports:
      - "8081:8080"
    environment:
      MYSQL_HOST: mysqldb
      MYSQL_USER: root
      MYSQL_PASSWORD: root
      MYSQL_PORT: 3306
    #    depends_on:
    #      - mysqldb
    networks:
      - appnetwork

  mysqldb:
    container_name: mysqldb
    image: mysql:8.0.28-oracle
    command: ['mysqld','--character-set-server=utf8','--default-authentication-plugin=mysql_native_password']
    volumes:
      - dbstore:/var/lib/mysql
    ports:
      - "3309:3306"
    environment:
      MYSQL_DATABASE: facturx
      MYSQL_ROOT_PASSWORD: root
    restart: unless-stopped
    networks:
      - appnetwork

volumes:
  dbstore: {}

networks:
  appnetwork:
    driver: bridge

Answer 1

我更改了我的Dockerfile：

# Build stage
FROM maven:3.8.4-openjdk-11 AS build

WORKDIR /app
COPY ../../facturx-ws/. /app
COPY ../../facturx-ws/src/main/resources/xsd /app/xsd
RUN mvn clean package -DskipTests

# Package and Run stage
FROM openjdk:11.0.14.1-jre
COPY --from=build app/target/facturx-ws.jar /usr/local/lib/facturx-ws.jar
COPY --from=build app/xsd /usr/local/lib/xsd
#COPY app/facturx-ws/src/main/resources/xsd /usr/local/lib/xsd
RUN echo "ttf-mscorefonts-installer msttcorefonts/accepted-mscorefonts-eula select true" | debconf-set-selections
RUN sed -i'.bak' 's/$/ contrib/' /etc/apt/sources.list
RUN apt-get update; apt-get install -y ttf-mscorefonts-installer fontconfig
RUN fc-cache -f -v
#EXPOSE 8092
ENTRYPOINT ["java", "-jar", "-Dspring.profiles.active=docker", "/usr/local/lib/facturx-ws.jar"]

我通过运行ttf-mscorefonts installer来安装windows字体。

Answer 2

例外情况是:没有找到“Arial”字体。请注意，当使用spire.pdf在非windows系统上转换pdf文件时，需要确保文件中所有已使用的字体都已安装，否则应用程序可能会抛出此类异常。这是一个关于尖顶论坛的类似职位。
