Java 使用jacob 工具 實現excel 轉 pdf （僅適用於windows）

前期准備：

　　我的環境：jdk1.8,  maven 3.3.9，  office2010

　　工具下載： jacob.zip   

　　下載地址： https://pan.baidu.com/s/15ro6zlpfCgo0mopOJkWXMg 提取碼：BRr8

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

環境配置：

　　下載完jacob解壓后：

將上圖畫圈的（電腦是64就用64那個，32就用86那個）復制到jdk  bin目錄下：

然后將解壓后的 jacob-1.19 文件復制到maven的庫里面：

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>
