关于使用jacob+poi插件实现编辑Excel转PDF操作！

最近在项目中，出现了Excel转PDF的需求，找了很多方法都不尽人意。今天就将我实现的方法分享出来，所需下载，都已备好，放心实验！

1.需要的jar包和控件

jacob-1.19.jar

poi-3.13.jar

poi-ooxml-3.13.jar

poi-ooxml-schemas-3.13.jar

jacob-1.19-x63.dll或者是jacob-1.19-x86.dll(根据电脑系统选择)

上述jar和配置文件链接：https://pan.baidu.com/s/1pGEgN-Q8s4TV4h6shmcGPw 提取码：vkxf

2.配置控件

将jacob-1.19-x63.dll或者是jacob-1.19-x86.dll放到jdk的bin目录下。（一般这样就好）

有的电脑，如果报Comthread的错误，将dll文件放入对应的

jar包放到jdk/jre目录下

例：%JAVA_HOME%\jre\jacob.jar 配置环境变量，jar包放在对应的位置C:\Windows\System32或者C:\Windows\SysWOW64（全都放更放心）

导入jar包即可

如果是maven工程参考下方pom文件，（build标签根据自己创建的类选择）。

}

代码主要是jacob调用office的组件实现转PDF，像“Excel.application”和“Word.Application”分别是excel和word的组件，另外wps的组件也是支持的，如“KET.Application”调用Excel功能。

因为在项目中，需要实现删除sheetName为“数据输入1”和“数据输入2”的sheet页，然后进行转换。我使用了poi实现Excel修改操作，另存转换。（转换时会出现一个转换进度条，如果项目在Windows环境下部署，是不会在前台出现的，放心）
