使用docx4j 实现word转pdf（linux乱码处理）

使用docx4j 实现word转pdf

1.引入maven依赖

		<dependency>
            <groupId>org.docx4j</groupId>
            <artifactId>docx4j</artifactId>
            <version>6.1.2</version>
        </dependency>
        <dependency>
            <groupId>org.docx4j</groupId>
            <artifactId>docx4j-export-fo</artifactId>
            <version>8.1.1</version>
        </dependency>

2.代码实现

            fileOutputStream.close();
        }
    }

3.docx4j部署linux乱码处理

​ 3.1 复制windows的C:\Windows\Fonts\下的所有字体库，放在桌面的fonts文件夹里。

​ 3.2 使用xshell 将桌面上的fonts文件夹里的字体库，全部放入 /usr/share/fonts/chinese 文件夹下，如果文件夹不存在，手动创建。

​ 3.3 给文件夹下的文件授权

chmod 775 /usr/share/fonts/chinese

3.4 建立字体缓存库

cd /usr/share/fonts/chinese
 
sudo mkfontscale
 
sudo mkfontdir
 
sudo fc-cache -fv
