通过spire.doc.free将word转换成PDF时存在缺陷：只能获取前3页

一、通过word模板填充生成word文件

使用poi-tl实现word模板配置：poi-tl官网
在这里插入图片描述
2.添加pom依赖

		<!--生成word-->
        <dependency>
            <groupId>com.deepoove</groupId>
            <artifactId>poi-tl</artifactId>
            <version>1.10.0</version>
        </dependency>
        <!--工具类-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>5.8.23</version>
        </dependency>
        <!--word转换为pdf-->
        <dependency>
            <groupId>e-iceblue</groupId>
            <artifactId>spire.doc.free</artifactId>
            <version>3.9.0</version>
        </dependency>
        <!-- 无法引入时是因为maven的配置文件settings.xml配了阿里云镜像加速，这时我们需暂时将settings.xml中的镜像给剪切掉-->
        <repositories>
	        <repository>
	            <id>com.e-iceblue</id>
	            <url>https://repo.e-iceblue.cn/repository/maven-public/</url>
	        </repository>
    	</repositories>

注意：对于spire.doc.free依赖还是无法下载时，可以去下载对应jar通过手动添加jar至项目中：maven手动添加jar包

二、spire.doc.free实现pdf转换

1.将word文件转换为pdf本地下载
