Java 使用jacob 工具 实现excel 转 pdf （仅适用于windows）

前期准备：

　　我的环境：jdk1.8,  maven 3.3.9，  office2010

　　工具下载： jacob.zip   

　　下载地址： https://pan.baidu.com/s/15ro6zlpfCgo0mopOJkWXMg 提取码：BRr8

　　　　　　　https://files.cnblogs.com/files/onop/jacob_1.19.zip

环境配置：

　　下载完jacob解压后：

将上图画圈的（电脑是64就用64那个，32就用86那个）复制到jdk  bin目录下：

然后将解压后的 jacob-1.19 文件复制到maven的库里面：

最后就是pom.xml文件的配置：

        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>19.0</version>
        </dependency>

        <dependency>
            <groupId>com.jacob</groupId>
            <artifactId>jacob</artifactId>
            <version>1.18-M2</version>
            <scope>system</scope>
            <systemPath>E:/data/maven_repository/jacob-1.19/jacob.jar</systemPath>
        </dependency>
